Tonight I started deburring the parts for the cowl flap, which is a modification for the EXP119 engine I am going to install.
The cowl flap has a door that can be rotated into an open position to help cool the engine. The door mounts onto a sheet of thick aluminum that covers up the original exhaust channel. The exhaust is re-routed so it comes out of the engine compartment forward of the channel. At least, I think that’s how it works, we’ll find out.
