Default RE: Great Planes Extra 300 GP/EP


ORIGINAL: mach2

I looked into the rear of the fuse and didnt see any lead, but the belly of the plane was recovered because the original owner broke the landing gear out of it, so i guess it could be hidden. If not i just dont see why my plane is so tail heavy. Its flying good, but Id feel better if I had more power at this CG.

The rudder servo is in the bottom rear, but I looked up the manual and thats the way it should be for the GP set up.

Ive never used EP, but after looking at some videos on youtube of the Rimfire 80 that is recommended, that looks like a crazy powerhouse for this plane!!!

EDIT - hey frankeldan, you are in the Revolver thread too arent you? Anyway, Yeah, sounds like that rimfire is the way to go for all out power. I kinda want to sell the 55ax i just put in it and try electric. I hate how you cant hear anything but the prop (and only when its pretty close), but wow, that motor has got juice! Do you know what batteries the guy was using?

Im using a 12x5 apc at the moment because that's what the LHS had. I have a few xoars coming in a couple days from tower. Ive got some 12x4, 12x6, 12x8 and 13x4s coming. Ive got a couple 11x7s but im sure thats too small for it.

As stated after this post, move your rudder servo to the tray for balance, but DON'T trade out the metal gear servo for a nylon gear. It isn't enough weight to worry about and if you bash the rudder, you'll run a risk of stripping / chipping a gear tooth or several. I started using MG servos on both rudder & elevator on aerobatic planes because I stripped a rudder servo when I was doing wild-***** stuff. When I landed, yes I saved it, the elevator hit and chipped two teeth on that servo. I changed both out to MG servos and haven't had any probs on any of my aerobatic planes since.
