I have a kit for an original PDQ Baby Clown in my stash. The box is destroyed, so it has no collector value. I would like to build it, but I remember the first one I built. I put a McCoy .098 on it and it was underpowered. I then put an OK .149 on it and it was still underpowered. The OK would catch fire when starting and one day it burned to the ground. I have a much better selection of engines today. Which do you suppose would work best?
TD .049, Fox .07, Queen bee .074, TD .09, Medallion 15, Fox 15 steel fin, Fox 15x?
