RE: CAP 232 / OS FS70II combo
Hi,
I had a Kyosho CAP 232 with an OS 70 surpass and it flew great. Not sure how experienced you are, but as it has a tapered wing, you'll need to keep your airspeed up a bit, but dont get too panicky.
Try and do a reasonable take off run to let her gain speed, rather than yanking off the deck too soon, and then take her up high and slow down to find the stall.
I flew with APC 12x8 and 13x6, the 12x6 will be fine for the break-in.
The motor should pull just fine, much better than a 52 4st.
Enjoy!
Wes
