Hello All,

I'm fairly new to giant scale. I have just purchased a used Dave Patrick Extra 330l and I need some help with some questions I have. Any help would be greatly appreciated.
1. I want to put a gas engine in this plane. I just dont know what to put. I'm not really into 3d. So I need an engine that will be good for aerobatics and maybe a litte 3d once I learn how to do it. What would be a good size gas motor to put in this airplane? The Dave Patrick website says a moki 1.8 glow is too much. And the guy at the hobby shop said anywhere from a g38 to a 45cc motor. Would that be too much?
2. What type of servo's should i use? Some one told me I needed 170oz torque on 6 volts.
3. I found recomended throws on this airplane but not the cg range. Could someone help with the cg?
I would really apreciate any help you could give me. I've tried 2 or 3 other sites and have not gotten alot of help. Thanks in advance.
