Thanks a lot for the responses! This is a .40 sized Aero-Works Edge 540. I talked with the owner of the local hobby shop with a lot of experience. His son competes in the tournament of champions etc., it's the Hobby Barn here in Tucson. He said that if the gear gets too far forward the airplane will have a tendency to bounce and if it gets too far aft the airplane will have a tendency to nose over. I fly off of a dirt field. I'm still not sure which direction I will put it.
