ok, I pushed the expensive button... it's on it's way

Av8tor, or anyone that flies a large stick in a "spirited" fashon, what servos should I use? I looked at an online manual and it said standard, but is that really enough? I was thinking something around 100ozin and faster than a standard servo... opinions?

I'm going to wait on the engine choice for a little bit, but I'm leaning twards the mac, I started porting it a long time ago (it was my first conversion), need to go over it again and see where it sits... the muffler needs to be redone, I only put on one 1/2" tube, I now have some thinner wall stock and need to put two on...
