I've got evolution 36 engine on this and the plane weighs 3 lbs 7 oz. The quandary is to get any where near the cg I will have to add 6 oz more weight to the nose. I also have a evolution 46 that weighs 8 oz more then the 36. So do I add the 6oz of dead weight with the 36 or put the 46 on it. My theory is if I gotta add weight I'd rather it be usable. I think the 36 will be plenty of power for the 4 lb plane I think the 46 will be over kill but I hate to just add dead weight. What do you guys think

Are you sure you need the nose weight? I had built many of these and a rearward balance point is okay. What is the current balance point?
