Hi all I was woundering if aynbody has a small cap with a wing span of 43 1/2 inchs I have a K&B 45 on it and I have about a pound and 1/2 weight in the nose to balance it the battery is as far forward as it can go. The cg is between 75mm to 85mm i have it set at 80mm the problem is it wont get off the ground I must have run it at least 100 feet at full power I think there is to much weight up front for the elevator to rotate the nose up any help would be nice michael
