Hi
22 years of flying RC more than most20 plus planes flying
A 60 size stik now with an OS 75 AX -strongest 75 I have foundturns a 13/8 APC
Have slight anheadral built into the wingflys better
Great second and lifetime Keeper
I will never be without one
I have at least 1500 flights on her and is always an enjoyable day at the field
One of the very few planes that was designed just for RC flight
The original 40 size was designed by KRAFT to test his radio equipment decades ago
The 40 size STIK is another keeper but bigger flys better
They fly GREATlooks and being different are a different storybut planes that fly the best are why we are in the hobby
Regards Tony
