Phil, what kind of scale did you weigh your Cap with? Did your Cap have standard servo's in it? How much does your friends weigh?

I think there are two different agendas with this airplane.

1) Put a heavy 2 or 4 stroke on it and have a brick that will sequence well, have unlimited vertical, but will not 3D worth a hoot.

2) Be weight conscious, put a light 2 stroke 50 or a saito 72 have unlimited vertical and 3D like a 35% airplane.

Rickys Cap in post #17 fly's like a TOC bird. He has 50 degrees of throw on the elevator. I have flown it and it does every 3D move in the book.

Incredible walls and parachutes at full elevator (50 deg) with no snap. This is due to wing loading. Put a 91 four stroke on it and all you get is a snap.

So I agree with you Phil, if 3D is not your game, put a chunk up front.

If you want a serious 3D capable bird, an OS 50sx is the perfect powerplant. DO NOT put a 90 four stroke in this .40 size kit.

JMHO
