Right Steve, but when are you going to get in trouble with a tail heavy model?? It aint gonna be when you are going mach .9 and you have plenty of elevator authority. It will bite you when you slow down. When do you slow down? When you get in landing configuration. What do you do to get in landing configueration? Extend the gear. ALWAYS balance your models in landing configuration and especially when the gear extension will cause a rearward CG shift. Scotty
