hanger 9 cessna 182
You'll find many kits and ARF's that have the firewall angled for basic right-thrust of the listed (recomended) size engine(s) This has the motor mount bolted flat to the firewall (no shims) and the engine mounted straight on the bearers.
On the GP Fokker Dr1 ARF, there's about 7 deg right thrust built into the firewall. That's 1/2 inch difference in clearance of the prop on the right and left sides of the cowl.
( A reminder to check the engine monting with a prop {and spinner...} on and the cowl in place...)
I don't know about the H9... The GP C182 neded a 3/4 inch spacer between firewall and engine mount to bring the prop forward of the cowl. Measure several times before cuting the first hole in the cowl... We had a relative beginner partially mess up his fiberglass, cutting for the engine mounted too close to the firewall... then finding out a prop wouldn't clear the cowl at all.
