That's my bad Red. I meant 6" not 6'. Thank god I fly better than I type. Also the wing loading on a model is so light compared to full scale the groud effect is a lot different. Example, on a slow & low pass with my Pizzaz
on a sunny day the plane will sometimes gain a liitle air when it crosses from the grass to the black surface of the runway. The thermals really get a hold of these little planes. The missing Ultracoat on top of my rudder
can atest to that. later daveo
