Nice job George. It does like to be flown all the way to the ground doesn't it? I've mixed in a touch of flaperon on mine.
Could I ask what prop/motor/batt you are running? I've got a 10x6/Turnigy Park 480/3S 1800mAh, and it feels like it could be more fun with something beefier
Formation flying soon? Might have a squadron of these soon (you listening Chris M? )
Thanks for posting the video and comments. Second flight was better, did some knife edge and spins, but again the landing was off. I'll upload the video when I have a chance.
Yes you are right Claudio she doesn't like muddy/soggy grass for an instant stop and the wind certainly was pushing it off the runway. It’s not a glider and will tip stall at any loss of air speed. Must be landed with reasonable speed and power all the way home.
Ok first thing guys don't use the small short clevises that came with the plane. They are weak and too short to lock the horns in, any little pressure and they pop out, even with a tube/ring. I changed them all.
I also coated/brushed the firewall and all the balsa under the cowl with thin CA to toughen it up (read this on RC groups).
I used a 3542 1000kV motor (Aeolian branded). Fit perfectly. 40A FMS ESC I have from my B25. Prop was 11X5 and nanotech 4S 2200mAh pushed all the way forward to get the CG right. Lots of Expo 60%+ on all to tame it down.
Flies well on half throttle hardly used full power in both flights. Should get 6-8miniuts out of the 4S 2200mAh easily.
I think with the smaller motors (480), use a bigger prop 12x6 and a heavier 3S or would be better on 4S.
See you at the field next Saturday for 3 X Sbach air show.
