Oh, thanks for the reply. I know what it is from your description. They do make solid spinner nuts that hold the pro on the engine that look just like that 'bullet', I have one! I"ve read where it should be positioned just aft of the CG which is not practical since it would be on top of the wing. I assume you beefed up the area pretty good.

My next project isthe Dynaflite with a Super Tiger 3250. I have the engine and a G38 as well but the ST is compact, lightand a wicked strong! I will run larger wheels and pants. I'm building it as a tow, so I'llbash scale a little bit. Thanks again.
