took the pro yak with the 55ax out today and the wind was around 10 to 20 mph whet a blast,last flight doing a water fall went to pull out and had no elevator control so i cut the power and used rudder to try to slow it down as it went in.only danage was the elevator and stab ripped off will be in the air again this weekend

Dang that stinks! Sounds like she was pretty tough bird and you did a heck of a job getting her down relatively safe. Good job!

will a 75ax be too much for the pro yak?if so will it fly the razor yak and do 3d or will it be under powered?

the 75 would be fine for the Razor Yak...

what size prop like a 15x4?

I'd say a 14-4 for the 75. We run a 15-4 on the 91FX.
