Thank you for the info guys
My actual plans is to put my eagle II on floats with the os 72a , my thinking is if i have more torque to compansate for the float weight and the resistance of the water.  I think the floats will add more clearance for a bigger prop as well.
I have built and flown this plane for a long time already and i master it prety well , it is a very nice trainer , it can glide for quite a long time if you ran out of fuel , lol .
I have already the os 72a engine and the os 46 ax who is already in it.
thank you .
