okay, bravogulf, the plane heard you. it did not come back.
well what happened was it flies real nice like, but gets a nose up/waaay to much up elevator (not my doing). it did this a few time and the last time it did not recover. did a very nice half loop into the ground.
all in all, it was a very nice plane. i think the elevator linkage came undone.
got to build another one. the oversized wing was great!
right now im building a glider to tow behind it.

i got a 50% fuse hanging, i think im going to finshed it the same low wing. 1S, will need more than 2 motors, tho!

i think a 5 inch chord, 30 inc span should look good.

This is my version of FT twin used to launch a shuttle. Noticed I redesigned the tail so that I can use it with ducted fan wing given it a "2fer1" transport. Only bad feature I found is the main gear is not wide enough to prevent tipping over when it is windy or gusty.
Built another transport based on FT having a swing wing to investigate STOL capabilities. That is a lot of fun to play with.

Great flights and Vid editing !

I especially like the T-Tail / Starlifter treatment.

I really enjoyed that. I was thinking c-17esque, at any rate the t-tail looked great!

I've looked around the different threads and the use of counter rotating props doesn't seem to be something that is required. I'm wondering if having the props turn opposite each other is a requirement? Can they turn the same?

counter rotating props (contra?) is mostly for torque roll and single engine flight. having a single prop rotate (one a twin with only one engine) a certain way helps to counter act the adverse roll when flying single engine and lets you have a greater power setting. (at least on the full scale planes)

many planes did not have this. IIRC british P-38 had same rotation, while american had counter rotation props. the Mossie had same rotation.

back to the twins...
the bigger ones seem to not need it.
i built a DD 25% with twin 44mm props with waaay over powered motors (1:1 or close) and i did have some torque roll, not bad, but noticable. this was a verry light plane, very small. other than that, ive never needed counter rotation, tho i have used it many times and many times without and it seems to me, at least at the 35% scale, to not need it.

i talk too much.

The video was done by a member of our club whose does this for a living.
The T-tail was incorporated to duplicate the YC-14 turbofan that they experimented with. Here is the way I set this up.

Yes. My transport is a scratch built and is a cross between FT and Mikey's. This is an earlier picture of the set up using 64mm EDF's.

Only problem with T-Tail is you have to gather speed before it comes alive.

Great job on the starlifter and shuttle ... I and another club member did one with balsa planes back in the early 90's ... We did the same shuttle lift off nose high the first few times and soon found out that it was better to let the mother ship go into a slight dive and then release the shuttle in a slight dive worked better so as not to stall out the shuttle right over the mother plane . Our heavy balsa shuttle could only make a 90 degree turn from 200 feet up and then it was pretty much time to land ... can anyone say flying brick

maiden tonight i hope!

edit: AUW is 69 grams, 5 lighter than the Pz mosquito, LOL. i built a piece of crap and its still lighter than the parkzone plane!
It might needs some refinement but it looks cool...a little bit of paint and you build yourself a very cool cargo version...nice work man

Some landings


So this is my first flight since my first big crash! plane turned out better this time 2nd scratch ever. I redid my battery box to allow the use of 2x 5000mah 45c 3s batteries. close to 6 lbs this time lol flys very nice, slow flight is way cool high alfa flight is ok likes to wagg the wings. one vid has some flybys next has a landing and a very steep pull out.
