Nope, nothing at all wrong with excess power. My concern is prop size/clearance and having to redo the firewall and engine mounting if the CG is now too far forward with this configuration. I would have to do a major rebuild of the firewall and engine mounting if the CG is too far forward to be able to move the batteries back at all. I should be able to run a 20 inch prop, but any larger may be an issue. If its drastically overpowered, I would rather have less weight and buy a smaller motor if needed.
