I have a question about the DP Super cub. I am finally starting to put mine together. I am installing a YS 140 sport on DuBron mounts.
After mounting the engine to the firewall, it came out with less down thrust than the front of the cowel. The cowel is pre drilled and we have to match the engine to the cowel. I had to add down thrust to get the prop to match the angle on the front of the cowel. My question is do your super cubs have some down thrust as well as fight thrust?
