I've been drooling over this plane for a couple years.

I intended to use a 40cc gasser as well.

I think 2 servos about 50--70oz in the tail for the elevators. 1 rudder servo--probably 100oz. You could mount it either pull/pull up in the fuse--or if you need more tail weight put it in the back as a push/pull off just one side of the rudder.

Mount the elevator servos up high and the rudder servo towards the bottom if you have to stick it in the tail.

Keep the engine box strong and don't drill any lightening holes in it.

The only thing thats kept me from getting the plane is that it's a kit. I build 2 or 3 kits per year. I just finished a 4*120 a few weeks ago and I'm kinda burned out on building right now.[sm=drowning.gif]
