I am a small planes planes freak. Nevertheless, this last months, wind is always strong! Too strong for my foamies.

Thus, I decided to build a bigger plane...
Kit arrived yesterday.... Never seen such a quality from them!

SAM association made a gathering in our club...
http://www.sam-belgium.net/chapter20...ex.php?lang=fr
Our club is in Belgium somewhere "in the middle of our small" country

Some pictures of balsa, tissue covering etc. A lot of them were "new builds electric powered". A pleasure for the eyes and the ears, for those remembering the noise of a Cox Tee Dee or an Enya 0.9 without exhaust... I used to fly mainly with cox 30 yers ago.... I know what I mean....

Show was superb: congrats guys ! ...Continue Reading

Flite Test presents a very nice small plane: FT Mini Speedster. Available as a kit or as a plan. The kit seems me extroardinary and very inventive.
I used the free download plan in order to build mine lighter mainly from 3mm depron and cardboard.
http://www.stonekap.net/ftplans/FT-M...ILED-PLANS.pdf

This small RET plane is currently one of my favourites. I am sure the original kit is stronger than my version but I am always searching for very light planes even if weaker.
http://flitetest.com/articles/ft-mini-speedster-build
I fly this plane indoor: a real pleasure. She is very neutral and distinctive from other RET planes I tested. Speed range is wide and she remains very precise from low to high speed.
Design is brilliant and other pilots found this plane very nice.

Being completely noob on this subject, I elected to start by buying a ready to use full set, avoiding searches and tweaks.

It's a blast: you unbox with care as f.e. camera micro antenna is fragile, you put the glasses on, connect the camera with a micro battery and it works!
Beware: According to the manual, always install antenna's before powering on or you could fry some electronics.


Installing them on my trusty Magnum Reloaded indoor plane took some minutes. My installation permits to adjust position and orientation on the fuse by just moving the 4 pins.

First Indoor flights and first FPV experience:
- I tried first a full battery taxying... It's safe and a good way to observe the "room"
- First fly: I was standing and after 2 minutes was as drunk!
- Second flight: I sat on a bank and it was a lot better
- Camera drains a lot of current and I made last flights with a Walkera 260 mah battery and an adaptative harness because camera stops in a second when battery is low.. Not fun at all.
- Googles strap is made to hold the battery but it's not strngh enough: I added a velcro around and it solved the problem
- I reduced the travels on all commands in order to soften the reactions of the plane and it was very funny!...Continue Reading

I built this plane according to a plan found here...
Andy Whitehead's design
http://www.rcgroups.com/forums/showt...6#post29544018

Bigmig indoor depron Profile jet (1 min 5 sec)


- Wing span: 58 cm
- Mean chord: 16.4 cm
- Wing area: 9.5 dm▓
- 102 grs with batt
- 10.7 grs/dm▓ wing loading
- 4 x 4.4 grs servo's
- 3 grs reveiver
- 6 a esc
- Turnigy 2 s 300 mah batt,
- Turnigy 1230, 12mm diameter Inrunner 4500 KV & GWS 3x2 prop


First flights with a 3 x 3 GWS: nice to watch, "realistic" but missed some power, needed to be piloted as an edf outdoor: keep speed,
Motor was very warm!
After discussion on RC Groups forums, I got advice to test on the bench with a 3 x 2 and low timing ESC: result is a 88 grs trust & 3.7A consumption!
Second flight session was a blast: nothing to compare! Power, nice to watch, not necessary to use 100% power and as a result a more pleasant sound as full power indoor "screams".

It's one of the most famous antique planes meeting in Europe I attended the 7th June, 50 km south of Paris.
Around 150 antic planes displayed and flying... I share with you just some pictures to motivate you to attend such an event!
Hearing in true life the sound of the 2480 hp of a Sea Fury, seing 2 Junkers 52 flying side by side, a B 25 taking off in front of you or a Rafale making an inverted low pass at 800 km/h is not to compare with watching the same on Youtube...

I bought this EPP kit from Staufenbiel in Germany. 40Ç.
http://www.modellhobby.de/MINIPROP-S...rodNr=232F7160
The kit contains EPP pieces and some hardware.
You need to buy motor, esc, servo's, receiver and battery.
This is my first vector jet.
Pieces are well cut and fits nicely.
Building as usual from EPP and inserted carbon strips and rods glued with Cyano.
I used big square hardwood blocs as templates and weight to ensure flatness and squareness.

Motor: Turnigy D2822/14 Brushless Outrunner 1450kv ,48 grs with backplate and propmount
Esc: 25A turnigy
Servo's:HXT 900 9 grs servos
Battery: 3s 800 mah
12 A full throttle => 144 w
Ready to fly: 379 grs all inclusive.
Balance: 47 cm back from the nose tip
Ailerons and elevator throws : 20░ up and down.

Seems me possible to save 5 grs on receiver, 10 grs on esc and wiring.. not more.
6 grs servo's seems me too weak (gears mainly)
I maidened with a 8 x 4.3 but current prop is a 7 x 4.
Consumption on the 8 x 4.3 was too high at 17 A. The 7 x 4 drops consumption at 12 A thus perfect for this motor and reduces torque effects.

First flight revealed impossible to turn to the right! I adjusted side trust to the right and inserted a small 6 grs weight in the right wing tip!
My mistake was a motor mount slightly glued with a left side trust, maybe one degree but in addition with the torque was a big hint!
Flies now great, I did already 10 packs with great pleasure! I even manage cobra's !
It's already...Continue Reading

Hydravion Magnum on floats (1 min 8 sec)



Magnum reloaded on floats.
280 grs ready to take off with 24 grs HK outrunner, 2 s 450 mah, 8x 4.3 GWS prop, 2 pces HXT 6 grs servos. Floats consume a lot of power in flight because of their weight and drag while taxying thus flight time is limited but a real pleasure as I can nearly stop the plane in the air...
I am unable to count the pleasure I got from Martin Muller design planes. My first one was a "Magnum Double" with a brushed motor some 10 years ago.... Fuse was an insulation pipe tube.

I build according to a plan this version some 3 or 4 years ago. Plan from all4's found here on Rcgroups. I test flew it in a bare minimalist version. From transformations to improvements, the current one (always the first and alone one I build transformed and painted) is a well maneered plane, predictable, reactive, very sane... One of my prefered indoor plane.
Turnigy 1818 outruner, 3.7 grs servo's, 6 A esc, 3 grs indoor receiver, 2S 300 mah bat. Ready to fly weight is 88 grs. Lighthess of my indoor planes is an obsession I am proud as it's one of the success keys.

I build the Scooter from a plan found here:
http://modell-aviator.de/modelle/kur...er-aus-depron/
This German mag place each month online a free to download pdf plan.
Designer is Lutz Nńkel

I was seduced by its uncommon shapes !
To be honnest, fuse building is not that easy!
HK10 grs outrunner, gws 7 x 3 prop, 6 grs servos, 6 A esc and a 2 S 300 mah lipo
Rtf at around 140 grs.

I modded the plans in order to make the wings removable for storage.
Therefore, I made as from the plans recesses for the wing profile but added a second layer of 3 mm depron and vertical 6 mm depron strips. This was made on the fuse innersides before assembling. I beveled the cuts for the wing resesses as dihedral on this plane is quite high.
The plan indicates a one piece 3 mm depron top but I prefered to make it in 2 pieces. First the aft portion, installing tails pieces, making the control linkages and second closing all the top.
Wings were cut in 3 mm depron, curved by hand on a plastic tube. I always cut my wings with the "smooth" depron side on the underside. Wings reinforcement are made by fiber tape strips on the underside. Wing struts are attached to the wings thanks to HK lightweight control horns.

Wings are inserted in cutouts and retained by bamboo wing struts and clips made from paper clips and some aluminium tubing. See pictures.

Micro indoor 30 cm wing
I found on the net some years ago a basic plan for an A4 size flying wing. I kept it on my HD disk just in case...
I build one to celebrate the opening of our indoor season and I am pleased. Some adaptations but basic scheme is kept: sory for the original designer I don't find anymore.
No carbon strip to reinforce but under the wing 2 strips of fiber reinforced tape.
All 3 mm depron except fuse out of a 6 mm EPP scrap.
0.5 mm piano wire pushrods
1.7 grs servos, a micro receiver and a micro brushed ESC from HK.
Mustang motor on a 4 x 4 gws prop.
31.1 grs with a s 160 mah lipo
Flies nicely but more like a butterfly than a jet: lacking of vertical power but I will try to boost it. First test with a 3 x 3 prop, changed for a 4 x 4 gws slightly cut but will try to change again for a better prop...

After my son build one with a KFM 2 wing section (see below) I was jalous and build my own with a KFM 4.
Great opportunity to compare flight character.
More neutral inverted with KFm4, astonishing flight for such a "stupid" wing section! I understand only from now the comments I red around those KFM wings! Congrats all the creators behind Funbat and KFM!

Build from a kit found here http://www.napolskimniebie.pl/.
The seller "Marek" is very easy to deal with and sympathic.
Kit arrived in no time in 2 separate box. I asked for a sanded and shaped version.
The pieces were perfect for someone who knows what shaping EPP is.

Building is mainly assembling and reinforcing with carbon strips engraved in the EPP. Up to you to carve the nose for battery.
Result is above my expectations. I took example on Marek in refining decoration and I don't regret it! In flight the wow effect is fabulous. At least in my eyes...
3s 1300 lipo, orange receiver, 4 HK 9 grams servos.
First flights with 19 gr Turnigy 2204 14 T were underpowered. Replaced by two HK 2205A 1350 Kv and 8x4 GWS and it's a lot better.
560 gr rtf with battery.
Flights are very good and predictable, just some more top speed could be appreciated! But the more I fly this plane, the more I thing the available power is realistic ans as the true one you have to "pilot" the throttle.

Here my son build of a Funbat: well done, precise, straight! Pleased and proud to test fly it for him.

All out of 6 mm depron, 5 mm carbon tube spar
Weight 259 grs with a 3 s 800 lipo and a Turnigy 2205A 1350 KV, a 8x4 prop, 18 A Esc and 2 HXT 900 servos.
First flights revealed a very well maneered plane:
- Slow flight able due to the light weight
- Vertical take off able !
Not as fast as a racer but funny
I observe what i think is a "snaking tail attitude" at some speeds and I will try tails extensions.

I miss rudders but we will soon ad them.

Thanks to "Der Frickler", a very active German Modeller sharing a lot on his blog http://der-frickler.net/modellbau I build my first boat!
From now I live along a river and this boat is intended to recover my hydroparkflyers in case of problem ;-)

Design is "simple stupid" and re using a lot of laying around parts... speed 400, gunthers, not anymore at the top servo, a DX5 i use for training people to fly, a small lunch box :-)

Thank you to you "Der Frickler"
