203mph wing

this is my 170mph wing, 1.3m span, 1.5kg AUW, Kontronik Mini Pyro, APC 7x10 and an old 4s Kokam 4000, the wing is foam planked with 0.8mm ply. It's built after this one here: http://www.rc-network.de/forum/showthread.php?t=198639 .
The plan was to go at least 250kph on 5s with the possibility to go to 6s if necessary. Seems I have to up my target to 300kph.

Fricken Awesome!! Looks fun to fly. That link to the other one looks super fast too. Thats definately interesting. I guess you could call it a "pylowing" !! Is it capable of 200mph?

I love tractor wings and Deltas! Great looking plane and seems to be very efficient (fast) as well. Congratulations!

5s should be enough, even a new 4s should bring it close. But not sure if I'm up to it.

200mph wing

I put a new slimmer fuselage on it and a new 5s/3800 pack. It now goes 327kph / 203mph. In-air current is about 95A on average or 1.5kW.
Had some aileron flutter at around 300kph, cured by taping the outside ends solid.

not much more than the one on post #1. It's really hard to catch on tape.

I did tape the tips fot the next flight where the 203mph were recorded. Reduced elevator authority quite a bit though, need more space to bring it down.
