Thanks Aki,
I am wondering how you managed to get the weight down to 5.1 grams?
The best piece of balsa I could find for the motor stick still weighed 0.85 grams. I did build the wing a bit heavier by using 1.0 mm ribs instead of 0.8, but I thought the stab was Ok at 0.4 covered and fin at 0.2 covered. Do you recall any of the masses on yours?
4.0 minuites is a very impressive time !! It must be close to the record time for a hangar rat surely?
Best regards
Tim
