Another Cal-Grafix order for numbers? I just got my quote back for $36.50 for the 416 number set, will be confirming the order. I purchased a TruTurn 3" Cub Style Hub for use with a 3-blade prop. It sits on the prop face and can be used with different props. I have a Mejzlik 3-blade 20 x 10 already, but will look for a XOAR WWII painted version. I may have to add weight to the tail, so am considering elevator servo mounting methods, one per stab.
