Another build tip for the Tango:

For the holes in the wings where the 1/4 nylon screws go through, I used thin CA to harden up the wood, then GENTLY smoothed the hole with a round file. I found that the balsa was getting damaged each time I put on, and took off the wing. Now its holding up great.

Flew it in some gusting wind up to about 8 mph, and it did fine. Great aerobatics and it didn't get tossed about any. Flaps set at 20% for take off and 45% for landing works great (flap settings are in percent, not degrees of deflection). I also like the power of the Power BL 46. Vertical capability, but not over kill.

My expo settings are 40% rudder, 50% elevator, and 60% aileron. After about 4 flights, this works good for me.
