RE: FOAMIE WIND LIMITS?
The Alfa and F/Styro scale warbirds handle wind no problems when flying high.
The trouble is trying to land them in windy conditions. Down near the ground, dirty air caused by ground turbulence just flips and flings them around all over the place. Landing becomes a matter of "hope for the best!"
They are best flown in winds UP to 5 knots, no more.
I have flown my Aerobird in stronger winds than my Alfa's. Not as good penetration (lack of power) but much easier to land in choppy conditions. (I don't have the undercarriage installed on it by the way)
Now an Aerobird with a Brushless motor. That would be good.
