Rationale

Pic FX65TAM78 Wild


After having clocked 1200 flying hours on the mythical F104 Starfighter during the seventies, I was eager to also have one in my model collection. Knowing how tricky the real one was to land, I kept a 2018 model of the Freewing 1:12 scale 70mm EDF PNP Deluxe kit in the attic during years. After having flown my Freewing T33 in Belgian Viet-Nam colors I wasnít afraid anymore of applying such a color scheme to the diminutive F104 (only 66cm wingspan). The choice of a particular scheme then was a no-brainer, I opted for the FX65 that I had the privilege of flying exclusively during the 3 month training and actual NATO Tactical Air Meet 1978 at Wildenrath (RAFG). It was a rare opportunity during which BAF F104ís wore the name of the pilot and crew chiefs below the cockpit during the competition week (not during the tactical week).

[U]Analysis/U]

The early EPS kit was light and its parts needed minimal time to assemble to obtain a USAF model of dubious flat colors (the tan looked much too brown) with glossy decals all over it. It was still preferable to the silver kit version because rubbing that off created even more of a mess in house. Although the fuselage measures 140cm long, the wingspan is a diminutive 66cm and calculates to only 7,03dm≤ wing area (compared to 25cm≤ for the T33), keeping the model light seemed paramount. As with the rest of their models, Freewing (labeled FNRC on the box) delivers good...Continue Reading

Waco E Series Cabin: While weíre on the subject of Wacos, hereís one of the highest performance ships they built.

The HRE, ARE and SRE cabin biplanes from Waco came onto the market in 1939 as competition to the Howard DGAs, Stinson Reliants, Spartan Executives and Beechcraft Staggerwings. It had a series of big radials up front from 300 to 420hp. The SRE was top of the line with a P&W R-985 up front. It had sleek lines and slim wings giving it a competitive cruise speed of 195mph. Itís wide stance, long fuselage and large flaps also gave it docile ground characteristics that some of its competitors didnít have.

The E series was unusually configured for a biplane. Itís upper wings were so much larger than the lower wings, it technically qualifies as a sesquiplane. It also had a very rare feature of having both the flaps and ailerons on the upper wings. It had comfortable room for four inside itís plush interior and it delivered its passengers in speed and style. And at a hefty price.

Being the high performance and complex airplane that it was, the E series came with a large price tag. With such a high price came a limited clientele, as only 30 E series cabins were produced. With big names like Lycoming and Goodyear tires being the purchasers of the airplanes, they were mostly used for high class executive jobs. But when the war rolled around, half of them were impressed into the military as UC-72s.

With a cursory count, there are six of these ships still...Continue Reading

Since one of the first questions asked when I created a thread about EdgeTX was "who is pfeerick", I thought I'd let you know.

I'm a beginner-intermediate multicopter and beginner plane flier, based in Australia. My main interests are actually in IT and electronics, so I'm often more interested in the electronics of flying, rather than flying of itself. My real interest really got peaked with FPV though, and I've since been flying several packs of a weekend, progressing from angle to full acro flight... from a KK2 board on a Hobbyking 250 quad frame to a F4 Omni running Betaflight on a timber flighttest h-frame ... adding GPS, telemetry, etc. I've also built two folding tricopters, and next up the agenda is a folding hexcopter or octocopter (not sure which yet) with full pan and tilt camera assembly ... maybe folding landing gear... GPS navigation capabilities, naturally...

I started off with OpenTX with a Turnigy 9X, having to hard-wire a socket so I could reprogram the Atmega chip. Then it was the 9XR-PRO (I skipped the 9XR). I was happy with these for a long time. Then I got the Radiomater TX16S, fitted the touchscreen, and waited for OpenTX to catch up. I'm currently still waiting. In the mean time, I was given a FrSky Taranis Plus (X9D+), and also got a Jumper T-Lite. I then heard about EdgeTX, a project being started by a developer frustrated with how long it was taking for touchscreen support to be added to OpenTX (18 months and counting) and jumped on board. Is it going to replace OpenTX? Not yet. Could it? Maybe... time will tell. But my TX16S now has a working touch screen, and there is a small thriving community starting, and everyone is talking about what can be done to make things better... no better place to be!

So there you have it... long-winded cliff notes about what's in a name.

Volantex Sport Cub 500 ( 60 grams flying weight )
Priced from $140 AUS to $180 AUS with or without free shipping . In oz expect about $20 for shipping . ( 180 is the banggood price )
It is a RTF and I dont think a BNF is available .
Protocol is V761 - 4ch

Hobbyzone Sport Cub S 2 ( Weight around 57 grams less battery )
Got mine for $160 AUS with free shipping ( Ebay discount voucher )
Usual BNF price is $200 AUS

So from a price perspective , they are very close .
The S2 is the larger of the two with larger control surfaces .
I will re-plug the S2 for batteries I have in large number , so flying weight might end up closer to 70 grams for the S2
Yet to do anything to the S2 , so consider this a quick and dirty comparison of two popular Micro sized Sport Cubs .
In the US you can have the S2 RTF for $140 USD , and the Volantex should be considerably cheaper .
Butt ? What about the flight experience ?
Which is better to fly ?
Im thinking it might go to the S2 as just looking at it - it looks a little more serious .

So I have to solder a new battery plug to the S2 , then bind it to the TX16s and set up the functions .
Then go fly .
It's raining again here ( Winter ) , but Sunday might be ok ?

The journey began as the apartment weather station showed 112F. The more accurate weather stations showed 104-106F. It was the hottest weather a lion ever ran in & the longest distance in such weather. The average speed had to be reduced to 5.4mph for the lion, yet the lion was still wiped out after 8 miles. There were some brief 6.6mph segments. Amazingly, the traction motors didn't die. What did die after 2.7 miles was the trackstar brushless servo. After power cycling it a few times & letting it rest, it managed to complete the run. It might have overheated.

It managed to outdo the mighty lunchbox. The lunchbox tires expanded & slipped off in heat.

The AeroScout S 1.1 is a nice trainer for those re entering fixed wing flying from glow power or new flyers with out any experience. The AR631 receiver and DXe transmitter are just about perfectly matched for stabilized flight or for aerobatics. With a talking DX gen 2 transmitter like the DX6,7,8 or the new NX6,8,or 10 the combination canít get any better. Horizon knows that the cost must be down to attract buyers so they chose to include an electronic speed control (30 Amp ESC) that does not have telemetry. This saves the buyer $20.

I train every Tues, Thurs and Saturdays (for non retired pilots) and have experience in the Apprentice and Mini, Valiant, Commander, Timber, UMX Timber, Conscendo A and E models, Extra 300 and various warbirds with retracts. The design of the AeroScout is the most forgiving and versatile designs so far.

I donít like pusher designs as they are inefficient, noisy and are not scale looking. The Multiplex Easy Star started the revolution of low cost foam trainers and is still a good design that has been copied and modified over the last 20 years. However the AeroScout seems to have the best features to date.

The RX (AR 637 or newer 631) is programmed by E flite test pilots that is perfect for beginners or experienced pilots.

Have had another light wind session with the AHI, same slope, but a hot sunny summer day this time with some booming thermals coming through. Was accompanied by a couple of hundred Crows and four Buzzards, made thermals much easier to spot, and my Ahi spent a lot of time circling at the bottom of the stack with those four Buzzards above , kind of cheating really, but did enjoy my session. Stopped of at the DS ridge on the way home, still had a bit of charge left in the second Ahi battery, and have seen a few videos of people DSing Ahi`s, what could go wrong? The main slopes are 80-100m high, but the ridge is about half that, so lift was a bit light, but once I had a bit of height, dived down the back and punched out into the lift at the front again a few times, needed to convince myself that it is possible to DS in this light of a wind. Then began a few circles and punching out on the first signs of slowing down, got up to 30 or 40 consecutive circuits before the inevitable happened, cross wind brain fart incident of some description sent the plane into the hill, now the rudder is detached. Damit, no willpower, just had to do it, but learnt my lesson, get some epp planes in the air for that, still, impressed it works in such a light wind though, and only have to tape up the rudder and its good to go.
In the workshop, have made a little progress. Forgotten just how sticky things get with a lost foam lay up. Think sticky the stick insect stuck on a sticky bun kind of sticky....Continue Reading

TX16s and the Volantex Sports Cub 500 (4 min 13 sec)


Ok , I was really pleased with the result of the 30% Rudder to aileron mix in beginner mode , so I did the same mix for intermediate mode . I wanted the Cub 500 to turn tighter for smaller spaces . I mean really tight . So If I tried real hard , I might be able to turn it inside a 2 meter square box now .
I like the ability to turn tight .

That TX16s really does fly the Cub 500 smooth .

Waco A Series: Speaking of confusing Waco names, the A series consists of the following models, BBA, KBA, PBA, RBA, IBA, TBA, UBA, ICA, KCA, PCA, RCA, TCA, UCA, PLA, and ULA. And the only differences between those models was the engines and minor changes to the wings and canopies.

The A series is extremely similar to the F-2 series with one major difference. What set the A series apart from the F-2, and the vast majority of other biplanes as well, was the fact that it was two seats side by side in the same cockpit. The wings, landing gear and tail feathers were otherwise essentially the same as the F-2 series.

This arrangement is extremely unusual for biplanes but it carries a few advantages. Firstly, this opens up a huge space in front of the cockpit for a very large baggage compartment that you would be hard pressed to find on any other open biplanes. Secondly, this allows for a single canopy to easily cover both pilots without being some large contraption with multiple sliding sections.

Another neat feature of the A series was itís brakes. The A series has a very large throttle handle on either side of the cockpit. Pushing this handle forward and back actuates the throttle as normal, but pulling it inward actuates the brakes. If you use the handle to actuate the brakes while also pushing one rudder pedal it gives you differential braking.

The A series saw a fairly decent production run but I would have a brain aneurysm if I tried to add up the actual number....Continue Reading

I may have found the solution to the A2 reading for our DLGs which are using a single cell LiPo and voltage booster as the A2 or Ain2 analog voltage input needs a reduced voltage to be able to determine the LiPo voltage. No one wants to install the FrSky Battery Voltage Sensor (FBVS-01) sensor from Aloft Hobbies as most DLGs just don't have enough room for this device which is a simple voltage divider capable of from 1-3 cell LiPo. We only need to cut the voltage in half, from 4.2 to 2.1 and use the correct multiplier in the OpenTX Sensor menu.
I went to American Science and Surplus this morning after flying and purchased some 10K ohm resistors 25 cents each and made a super tiny voltage divider for a 1 cell application and so far the test on the ELF is spot on.
So far the prototype seems to be exactly what we are looking for, a sub-miniature voltage divider of 2 10K ohm resistors soldered onto the booster weighing .5 grams and .085" thick by .186" wide.
