Rationale

Summer 2020 I installed a FrSky ASS70 airspeed sensor for test in my foam Parkzone Ka8b glider. I choose that one because the initial idea was to use it mainly in gliders and that one didn’t have a solid lead nose, and behind the foam was ample empty space (for the factory recommended hook servo that is very dangerous to use because it doesn’t allow release during failsafe conditions). After a few testflights I was convinced of the advantages of such a system if programmed to provide airspeed figures through my earphones to help me judge the speed in the pattern and thus enhance control of my touchdown points in the various gliders I operated. With age I noticed I was getting difficulty judging the speed of the various sized gliders and that cheap system could easily compensate that. GPS modules only provide groundspeed and that is utterly unusable in a moving air-mass (which we call wind). To measure airspeed you need to measure the amount of air that flows around your wings at any given time, independent from the air-masses’ movement versus the earth.

system description

The FrSky ASS70 is a so called low velocity/low precision system (still up to 270km/h) that costed only 34 euro and included a scale looking fighter-type pitot-static tube of 7cm protruding length, a lightweight sensor unit, a long flexible tube to connect total and static pressure between both parts, a male to male electric connector to the FrSky Smart-port entry in the receiver, and an...Continue Reading

Rationale

In 2014 I stumbled upon an advertisement of a second-hand Fly-Fly F100 in flying condition for what seemed a reasonable price. Some time before that I already had purchased one of the last original kits of that brand because I ever wanted to make a nice model of the French Air Force two-seater I had the chance to fly just weeks before it was phased out. Even as the second-hand one was in a sorry state, I bought it to use as a trainer and eventual source for spares if the need aroused. All of that laid dormant together with other kits and aircraft on my attic for years. End of summer 2020 I had a two week lul in my program and thought that getting the second-hand one ready for some test-flying with various EDF’s I had collected would be a useful way of filling that time. Once in my workroom I was very disappointed about the way that model had been very grossly assembled and decorated. The guy I bought it from had been a firefighter at the airbase of Beauvechin and should at least have been familiar with the fact that the USAF star stood on two legs instead of on its head!

Pic 0017c


Speaking of legs, when you see how the nose-gear had been fastened to the fuselage you get an idea about the craftsmanship? of that modeller. I think he used a complete jar of Gorilla type glue on that model. Furthermore duct tape had been used to cover other atrocities before being painted, and during sticker application he had not followed the deep crease...Continue Reading

Motivation
End 1972 after coming back from the USA with my silver wings military pilot qualification on T41/T37/T38, I flew five rides with the already at that time venerable (since 1953 in Belgian Air Force) Lockheed T33 for familiarization with the Belgian environment and procedures before I started my conversion on the Lockheed F104G Starfighter. Although its official name was Shooting Star, most pilots always refer to it as a T-bird. Years later I also had an aerobatic ride in its Canadian counterpart, the Rolls Royce Nene powered CT133 named Silver Star.

Pic FT14 filtered


Soon after starting EDF model flying I was looking out for a T33 R/C model but either they were large and intended for real jet engines, or didn’t look the par. When Freewing marketed one with an 80mm fan in 2019, it immediately got my attention. That model is a bit small but makes it be easily transportable even fully assembled, and the relatively large diameter wheels allow it to also operate from well-cut grass. Straight-wing airplanes are more forgiving and can be flown slower in tighter airspace. Mid 2020 I ordered one from Motion RC Europe and within days I had it home, together with one of their admiral 6S4000 batteries that claims 60c output! (I need that to get airborne from grass without rolling too long and stressing the retracts).

Analysis
The model was nicely packed and could have been assembled in a matter of hours, just a straightforward affair. The...Continue Reading

My original orange two-seat version V41 OO-LUK overturned at the end of the landing during a demo for kids at Tongeren in 2018. The only apparent damage seemed to be a broken rudder top and its hinges. Being the end of the season I put the model aside but had other priorities for (re)building. I always hated the shiny flimsy Monocote that had been patched up many times during its previous lives, sometimes even with transparent Scotch tape. Instead of only repairing the rudder, I decided to completely restore the model with Oratex/Solartex and give it another livery for which I already ordered the artwork through Calie. Instead of the standard Belgian Air Force trainer livery I opted for the black/white/red livery that was used by the period famous aerobatic team “Les Manchots” who pioneered close mirror flying acts with Stampes (V28 and V18) that had the front cockpit covered and a single pilot canopy installed.

Pic Stampe V28-18


When the Belgian Air Force sold their Stampes in 1971, V18 first was sold to a Canadian (based at Sollingen in Germany) and in 1978 to the UK, where it flew as G-BRMC. In 1993 the Antwerp Stampe en Vertongen museum at Deurne Antwerp acquired this historic valuable aircraft and registered it OO-GWC. They restored it to the exact configuration in which it flew during the 1960’s. It was rarely flown and in 1996 I had the honor and privilege to ferry V18 from Brustem airshow (for the 50th anniversary of the Belgian Air Force) to a commemoration...Continue Reading

First steps in 2014

Pic 5660cr


After flying indoor toy helicopters for a while I desired to purchase a serious secondhand helo to fly outdoors. Jan 2014 my eyes fell on an electro scale Hugues 500E in unattractive Danish Army colors, completely ready to fly and equipped with a Helicommand Rigid ground and air stabilizer, plus five 6S3300 batteries. I trusted that my skills with the Blade 120 and like, augmented by the quality stability system, would be sufficient to get it in the air to teach myself. The deal was concluded and after coming home I knew the first thing I wanted to do was to transvestite it into the colors of the famous Hugues 500D that was used in every episode op the worldwide popular eighties television series: Magnum. As painting gloss yellow over matte dark green would be very difficult, I opted to cover it in vinyl and purchased lengths of yellow, orange and brown. I couldn’t refrain from first making a picture of my acquisition next to a Blade 130X helicopter that I hand-painted as a German police BO105 instead of the omnipresent Red-bull dress-up.

I quickly regretted my decision to work with vinyl, applying parallel angled stripes shoulder to shoulder over angled and double-curved surfaces proved very challenging but I never gave up. In the end I started by first using see-through paper that I pushed in place hugging the surfaces, then marked where the previous strip ended, put the paper flat on the table and drew a new...Continue Reading

The choices
After building the Ka2b OO-SZD, Gö4-3 OO-SZC and Foka4 OO-ZEU in their historical Sabena livery, only one glider was missing to have them all, the 1958 Bocian 1c OO-SZE serial P311.

Pic Bocian HFI 2018(19)


For years I compared the available quarter-scale (short)kits, one from the UK, one from Germany and the one from the well-known Polish OldGliders. End 2019 I choose the latter and ordered all their available options (except the oleo gear) including a scale pilot. The reply I got asked me to transfer 805 euro, also covering the shipping to Belgium. Three weeks later DPD delivered a 8,8kg package. It had been extremely well packed with liberal use of triplex-wood around both cartons, then many layers of black plastic to protect all sides during handling. Don’t panic after opening the box, just as with any 1000-piece jigsaw puzzle, it only takes patience to assemble the awesome mess of single loose pieces. After unpacking I roughly amassed similar looking parts in heaps and took following picture of the complete delivery.

End 2017 I acquired a brand new (never flown) secondhand relatively cheap Taft Viperjet for its electronic components. With still to be assembled FlyFly kits of a Hawker Hunter and an F100D Super Sabre in the attic, I was in need of quality high-blade good 90mm EDF assemblies and that Viper happened to have been upgraded with a E-Jet EJ90-9 nine-blade 90mm fan on a HET700/60/1865 motor with a Phoenix edge HV120 12S EDF and Savox SH0255MG servo’s. That factory-balanced EDF set is advertised as producing 2030W with 91Amps at 22,3V: 3,1kg thrust! With the withdrawal of my FlyFly MB339 EDF trainer I decided to fly the Viper for a season before cannibalizing it.

Although the seller told me I just had to install a receiver to get it flyable, I spent more than a week getting it ready during fall 2019. The ESC had been screwed to a plywood plaque that had been glued within the fuselage, no way to unscrew it anymore in those confines. Since that ESC had no battery connectors I had to solder my EC5 plug within the fuselage, not an easy task considering the very thick wires and required heat within that foam environment. The wires also still had to be connected to the motor, necessitating the opening of the taped-over access hatch. That revealed that the fan-housing had been mounted with only two small screws, I upgraded that to six.

After mounting the receiver I discovered that none of the flight controls deflected properly. The previous builder/owner did cut the standard...Continue Reading

Chapter 1: Introduction to the Schemp-Hirth Gouvier gliders

Black and white picture of the real 1953 Sabena gouvier in flight


During the thirties, soaring became popular but the basic period single-seaters only allowed slow student progress by short hops along slopes. Some two-seaters were developed but in 1937 the first flight of a side-by-side two-seater (developed from the Gö3 Minimoa) opened up a new way of introducing more people to soaring, and offering a better way of teaching. The Göppingen 4 (abbreviated by many to Govier/Goevier/Gouvier but with different pronunciation in German, Dutch and French) had flight characteristics similar to the popular Grunau Baby but at 92cm width, the seating felt rather cramped. Space had been maximized by the wing to fuselage blending root-shape to accommodate shoulder and elbows. That part could be ordered in resin impregnated jute (sackcloth), the very first use of ‘plastic’ parts in gliders. The Gö4 was very successful and used by the Germans to train candidates before they joined the Luftwaffe. After the war the factory developed and built the shorter aft-fuselage version Gö4-3 that didn’t need as much balance weights when flown solo. Of the more than hundred Gö4’s built, as of 2015, only 3 remained airworthy in Germany and 2 in the Netherlands.

In 1952 Belgium’s national soaring centre acquired Werk-nr 415, one of the 21 factory produced Gö4-3 and flew it unregistered till 1954. It then was registered OO-SZC by Sabena...Continue Reading

Part 1: Prefabrication by French hobby builder Jean-Pierre Voisin

After a stupid priority choice following an unfortunate combination of events, my 4m span Fliegerland Foka 4 plummeted vertically in the ground minus its port wing during the September 2018 BiGGS meet at St-Truiden (illustrated story here) https://www.rcgroups.com/forums/show...02&postcount=3. As Fliegerland was out of Foka kits for a minimum of 6 months I shopped around and had to go for a 5 meter span version which I ordered from JPV, a Normandy retired builder (he has no website). A few months before that, I saw a fellow BiGGS pilot maiden one at Pottes and the quality of flight and the model seemed very good. The weekend after the crash I got in touch with the builder and within days I order a pretty much prefabricated kit consisting of a molded fuselage, styro wings with Samba (Abachi type) sheeting over 100gr glass-fibre ready for finish, ailerons and 400mm spoilers installed. Wings and tail rigging made, wheel installed, clear canopy without frame included. Removable rudder with built-in servo installed. That is a lot of work this amateur but very capable builder delivers (halfway via a trucker) for about €1500, after 10 weeks of intense labor. Basic fuselage and foam wing cores can be ordered for less than 500 euro if desired (or for repairs).

Regarding the choices I made: I...Continue Reading

Chapter 1: Introduction to the Tipsy Nipper

Pic at cox

How can you squeeze a person of normal height and shoulders into that tiny cockpit?

Aircraft history

In 1952 designer Ernest Oscar Tips started designing his diminutive T66 in the Fairey aircraft factory in Gosselies Belgium. As the Hawker Hunter license production ran down he started building prototype OO-NIP that was testflown with open cockpit on 2 december 1957 by Belgium’s famous test pilot Bernard Neefs. In 1959 production started on the closed canopy Mk2 that were powered by a 45hp Volkswagen, Stamo or Hepu engines with exposed cylinder heads, 64 were built till 1962 (+78 kits delivered). Because Fairey started producing the F104 Starfighter, the Nipper production was then taken over by Cobelavia that produced 18 Rollason cowled-engine Mk3 Nippers in a hangar in Kortessem (just a few km from my town and model airfield) till 1966. From then on production of complete aircraft (and kits) was transferred to the U.K. Slingsby built them till in 1971 the Donington based firm went bankrupt (after producing 32 complete aircraft). Later kit produced variants even boosted a 85hp Jabiru engine. Nowadays many still are airworthy in the UK, Belgium and the Netherlands.

The design philosophy had been to produce a lightweight single seat aircraft that was cheap to produce and operate, and easy to fly. Although not the smallest nor prettiest, it was the smallest practical aircraft and even had aerobatic...Continue Reading

Part 1: Introduction and choices

Purchased unfinished on a second-hand website in 2015, that 1988 Rödel kit had been lying dormant in its box and only assembled after 2010 by a new owner who didn’t complete it. That very rare standoff scale 1:5 model was larger than I had in mind (2m11 wingspan) and was too heavy for the AXI 4163/20 that I had purchased for a conversion of a 1:6 PC9 into a PC7. I sold the PC9 but this PC7 model still had no engine mount nor flaps, aileron servos were missing, and too long legged brand-less electrical retracts with dubious electro brakes installed. Upon inspection I saw that the assembly quality was ok, the model being of period traditional build with balsa or Abachi planking over a foam core for most surfaces. Although it weighed only 5,5kg as acquired, everything was made of strong quality wood with the fuselage painted and wings in Solarcover. White being a good base color for the yellow I was going to apply over it, we quickly agreed on an acceptable price before I loaded the model in my camper. Back home I had to rearrange the hobby room to stock that relatively large model, in the meantime I kept it in the living room in its partially finished Martini display team scheme. This was Jaques Bothelin's lead airplane HB-HMA in which I sat but never flew.

Disaster in Pottes

Last week of July 2017 BiGGS held its week-long gathering near the French border in Pottes/Celles. As I was the event coordinator I was kept busy all week and flew little. The almost constant force 3 to 4 crosswind also made things tricky and restricted the type of gliders that could be flown. Saturday had to be the highlight with the celebration of 40 years of the Waloon model association AAM with official speeches by representatives. Although I was reluctant I got a bit pushed to fly my historic Ka2b for the public event and assembled it for its 5th flight. This would be a short one because at only about 50 meters during the climb, the nylon snapped in the hook and I declared an emergency, joined a low downwind and settled down in a smooth landing.


I immediately joined the cue and rapidly found myself behind a new German tow-pilot who had lots of challenging practice that week. At around 200 meters he messed up a turn by turning too sharp but I was able to follow. At that time he spoke something to me in German but as I...Continue Reading

History

In 1960 the Polish factory SZD made another throw at high performance gliding in an attempt to break the German hegemony in this domain. Although still of wooden monocoque construction, their radical Foka (seal) design was extremely pure and streamlined (laminar flow over wings and fuselage), still looking futuristic more than 50 years later. It not only looked good, but after a couple of months gained 3rd place in the 1960 standard class world championship. It later astonished the glider community when the 24 year old Jan Wroblewski entered such 15m Foka4 in the open class and became world champion during the 1965 UK held championship, the one and only time a standard class glider won the open class title, and this in an aerobatic capable (+6 -3G) production glider. Production of the SZD 24 Foka4 ended in 1968 after 204 gliders, of which only 137 found an export customer. It acquired 7 world records with a 1:34 glide ratio, a maximum takeoff weight of 322kg and an initial speed range between 62 and 250km/h. Some are still flying nowadays but are limited in speed to 160km/h and G’s after some disastrous in-flight structural wing breakups.

History and acquisition

In 1968 shortly after becoming solo on a towed Ka4 Rhönlerche, I took place in the frontseat of a Belgian Air Cadets Schleicher Ka2 Rhönschwalbe glider for my first winch launch. By that time their surviving 1955 acquired Ka2's weren't used much anymore and I was glad to have had that ride in one of the 75 Ka2b airframes that were produced between 1955 and 1957. This also explains why the Ka2b figured on my dreamlist of model gliders since years, especially when I found out that a traditional wooden kit was available from Schneider Models in scale 1:3. The size of that model, 5m33 span and a 2m75 fuselage length was as attractive as scary to me. The kit consists of only the plans and some precut wood and canopy mold, building it would require the living room table to be neutralized during about two winters because the wings and fuselage are too long for my hobby room. The existence of Ka2b OO-SZD on the Belgian register, after half a century still wearing extremely attractive SABENA (former Belgian World Airlines) colors, was also a strong incentive to “ever” possess and fly a Ka2b model in this scheme.



A fellow member of the BIGGS (large-glider association) built one in 3 years time and it flies like a charm, I was hooked but that model is rarely found secondhand and often the painting prevents an easy switch to the Belgian desired scheme. Early summer 2016 one was advertised on a popular German model forum but the price was too steep and...Continue Reading

1) the search for a Twin II and a first analysis.

After having neglected the Belgian Air Cadets for decades, a friend of mine suggested I came along with my models for a courtesy visit. Instructors and cadets were very interested and they offered me some time and space to perform demonstrations on the vast Nato reserve airfield of Weelde. An even better deal was that they offered me a couple of winch launches in a Twin Astir, their standard trainer. I try to renew that visit every summer and got the envy to make a model of a Twin I flew in. Because theirs were purchased secondhand on the German market, not 2 of them are painted the same. For ease of seeing it in the air, I opted for the PL91 which in 2013 still sported all-orange flight controls and wingtips.



All BAC Grob 103's are of the Twin AstirII type. A search for a glider model in the 4meter class only came up with Twin Astir III types which have a much different wing shape. Early 2014 I saw an old second hand Twin II for sale by a Dutch modeler and purchased it. Luckily I did because I have encountered none since. That was the good news, the bad news was that the old yellowish model sported rough repairs on the tail and a canopy that held together with Scotch tape over numerous long cracks. The wings were in a nice custom linen bag that also contained wingtip extensions. The 350 euro I had to pay for it was steep considering the overall condition of the 3m55 span model and the very old servo's that were...Continue Reading

Part 1: The assessment

The Cub was never on my list of favorites to buy, but after a PC9 got ruined during delivery due to exposure to a storm on the Tarmac of Vienna, the E-flite Super Cub 25e was close to the reimbursed value and I took it as a compensation. Somewhere it fitted my desire to learn aerotow and fly the Super Cub as still used nowadays by the Belgian Air Cadets as towships . Pilot in picture below is Polle, former F104/F16 colleague who amassed 3000hrs of towing in these Super Cubs and presently flies a civilian one restored by his father in law in the yellow early colors of the Belgian Army AOP's. Although I performed some towing (gliders and banners) in a 135hp Super Cub (OO-VZL), most of my 200 hours Cub flying was done as an instructor (from the back seat).



Being scale 1:6,2 it will be a good match to tow my 1:6,6 scale Parkzone Ka8b that I also vinyled in period Air Cadets colors https://www.rcgroups.com/forums/show....php?t=1959173 . Although a quarter scale Super Cub must be better suited for towing, I really didn't feel like assembling and disassembling a strut equipped airplane on the field each time I'd go fly. This 187mm span model can be stocked home and transported fully assembled in my camper, a major advantage. It also is a nice field companion for my recently restored 1:6 scale Fournier RF5b Sperber motorglider in period Air Cadet color scheme https://www.rcgroups.com/forums/show....php?t=2565923

Although I had made up my mind not to buy any other model before I finished all the ones awaiting in the attic, my eyes popped when I saw the picture of an ultra-rare 2m80 span Fournier RF5b Sperber advertised for a reasonable price on a well-known German RC forum.



Besides having met an old friend who bought a full size RF5 and promised me a ride in 2016, I also remembered how often there had been suitable soaring weather but nobody to tow during the summer months. I had hoped to fill that void with the foam Hype DG1001M with retractable engine, but it proved too much of a toy and after selling it I was on the lookout for a a suitable traditional material powered glider with a motor in the nose, preferably in the 3meter class that I also could use it on the slopes, and representative of a real motorglider. I immediately wrote a mail to the seller and he rapidly agreed to sell it to me although he had two more offers. Two days later I drove to Germany to pick it up amidst a cellar full of other models young and old.

The seller had bought the model years ago from a German living in the alps, but had no idea if it was a kit or homebuilt because you never saw another one although the fuselage was in strong polyester/fiber. The model was more than complete and ready to fly except for a battery. It had an expensive engine in the nose, an ESC, Graupner servos, yellow, blue and clear canopies, two horizontal tailplanes and two different wingspar joiners. The gear was...Continue Reading

June 2011 I purchased a secondhand 1400mm FMS Spitfire from a club member who had only flown it once and found it much too challenging for him. I wasn’t a hero either at that time, but I definitely didn’t want to miss this opportunity because on the scrapheap of the clubhouse I had seen an almost complete but total loss identical model for takes. Having performed aerobatics in the back seat of the real PV202 (G-TRIX) Spitfire two-seater during the Oostmalle warbird meet of 1993, I wanted to fly that as a model as well.



A flight by an RC shop owner confirmed it was very unstable in pitch and dropped a wing during the flare. Inspecting the model I noted the elevator to be anything but rigid. The foam couldn’t handle the torsion caused by the control horn only on the starboard side, and the aerodynamically correct outboard balance sections twisted much too easily, thus exaggerating any elevator input and making the model very twitchy in pitch. I resolved the problem by cutting off those outboard sections from the elevator and gluing them with some carbon rods to the fixed horizontal stabilizer surfaces. It thus didn’t alter the overall shape, but drastically reduced the torsional forces on and between both elevator halves.



Because the model continuously ended up on its nose, I also increased the forward rake of the retractable landing gear. I unscrewed the gear from its mount and added triplex plates under the aft attachment screws. By doing that...Continue Reading

Having had a ride in the back seat of the leader of the Frecce Tricolori during the 1984 Sanicole airshow, the FlyFly/TopGun 90mm EDF Aeromacchi 339 model had been on my wish list for some time. I saw somebody else in the club fly this relatively large but seemingly docile model , and when I decided to get rid of my smaller EDF’s and standardize on 90mm fan models, I immediately thought of this as a proficiency trainer. End of June 2015 I saw a completed yet unflown one for sale on the secondhand market and purchased it for 200 euro.



The assembly and finish quality was atrocious, but the value was the Typhoon HET EDF 650-58-1760 Motor with an 11 blade TAFT fan, the rest was for the model with servos and replacement electric retracts and battery. I figured all those items later could be used on my still dormant FlyFly F100 Super Sabre as well.



The first detailed inspection at home did not make me happy. Servos seemed to be the cheapest HK variety, summarily glued into the recesses and covered by painted-over sticky tape. The reliability didn’t bother me too much because there were separate servos for each elevator and aileron, thereby allowing for half the control in pitch or roll even after a servo failure. The drag produced by the thick Christmas decoration letters with rough sparkles would have been enormous, and these were quickly peeled off.

When I started flying indoor during the winter of 2013 I had no envy to buy the traditional aerobatic generic Depron models that are so popular. My penchant for scale led me to buy a micro Spitfire from Parkzone. Changing the delivered UK colored model into the Belgian markings MH434 like it flew during summer 1991, added much more weight and caused the minimum airspeed to increase so much that it became difficult to fly in our limited dimension sports hall, its small size also made it difficult for me to estimate its real distance from the walls. An internet search for a more suitable model made me search for a larger biplane. It thus became the E-flite Nieuport 17 which I ever dreamed of building as a full-size replica and for which I ordered the Redfern plans in 1983. I never realized that dream (due to the lack of suitable engine at a reasonable price) but decided to at least fly a model of it in my chosen finish of a Nieuport 23 flown by the famous pilot Edmond Thieffry during the first world war. Removal of the colors and decorations on the original model caused so much damage that I had to use too much filler on the tail, necessitating additional weight in the nose, and the additional paint coats and decorations didn’t help keep the weight down.
