Is going to be fun lining up box to centre the prop adapter through the cowl. "Instructions" remotely allude to securing the box to the existing firewall by blind nuts & screws. Presumably in lieu of epoxy so can be removed if later converting to gas. Intend screwing motormount to new firewall with woodscrews (not supplied with plane or motor accessory pack).
On most of the models I've set up there is a big hole in the center of the firewall. I screw the motor to it's mouint, then I put a bolt through that and the firewall with a couple of decent washers to hold the engine mount and motor in place while I fit the cowl. Then once I get it all in the right place like that, I spot the mounting holes through from the motor mount to the fire wall and remove the bolt and washers.
