I fixed my post, the prop is actually a 12x4 I was thinking 6 pitch because i usually use 11x6
The guy at my Lhs said that would be the max length for that engine.
The engine is well broke in and has about 25 flights on it, and ive only used 11x6 on it.
I hope the 12x4 will work well, as im looking for a little added torque, and willing to sacrifice some speed.

Ive seen the cap 40 flown before, and it really is capable of about any sport aerobatic maneuver you can throw at it.
Its going to be a fun plane

RVman: The high torque servos are definitely more than this plane would need. I had them on hand before i bought this kit,
I bought 6 of the s3010 and three of the s3305 from tower hobbies a while back.
I got a discount for buying a group of three, plus free shipping, i couldnt resist.
Id like to buy a 60 or 90 size kit later, if so ill probably use these servos in it and put standard bb servos in the cap 40.

Alfredbmor: The 6 volt battery will more than cover the draw of these servos, as far as longer flights, im not sure.
they draw more current than the standard servos.

Im switching to 6 volts on my planes and future planes, mainly for insurance. In the event one cell goes bad, the battery still has
4.8 volts remaining to operate the receiver/servos. If a cell burns out on a 4.8 volt battery, its good bye plane.
A friend lost two planes due to a burned out cell
