I have just bought a 25 size CAP232 3D but I'm having trouble deciding on the engine.

The kit says that the flying weight (I assume) will be around 3.5lbs - 3.7lbs. I assume that is with the .25-.30 recommended engine size.

What engine would I need to put here to get it to hover and pull out with authority?

I'm considering

Saito 30 - Don't recommend bigger Saito... no stock until never
O.S. FS-30S
O.S. FS-40S
O.S. FS-52S
O.S. 25 FX
O.S. 32 SX
TT36Pro
O.S. LA .46 with pitts muffler

I'm leaning toward a FS-30S... but with a measly 0.5bhp, don't know if that will be enough to hover the CAP.

The second choice will be the LA.46 with the pitts muffler (slimline) but I'm afraid that it's just too big and the tank will last 4 minutes only...

What do you think? Or other recommendations?

It's almost done and I haven't chosen the engine yet!!!
