leedees,
Did you try the CG at the max of 4 1/8''? The 3 3/4'' is just a starting point. If your like me, once the plane has been flown the CG will need to be ajusted anyway. I'll be glad to get my engine in and see what mine is going to do with the CG.
Zippi,
I wanted to be very conservative with the CG at first and you're right, a little adjustment may be needed after we see how it flies. I have several options to move the CG back a bit. I can move the receiver battery or take off some of the weight in front of the prop or add some tail weight as Old Fart favors. I have to fly them a long time before I can decide where the CG should be.
Unfortunately, it's going to be another week or more before I can fly this beauty as the bigger of the two flying fields we have is still partly under water.
