Skyraider Mach II engine mounting problem
I am installing the engine on my mach II and ran in to a couple problems. First, the throttle rod is not long enugh to reach the carb. Second, it seems the OS .46 I'm putting on is bigger than what they figured so I can't install it as far back as they reccomend. The instructions say 4.3 inches from the inside of the firewall to the back of the spinner backplate. Well with the hole they provide for the Mixture adj I can only get it to 4 1/2 and it won't go in any furthe. will that make a difference in how it flys?

Probably not, but you can always enlarge that hole so the engine will go back farther. Just cut it with a razor blade or hobby knife, then hit the exposed wood with a film of epoxy to fuel proof it.

I mounted a GMS .47 in mine and it fit perfect!
You will want to mount that engine as far foward as possible,also loosen the screws that hold the engine mount to the firewall and spread the 2 mounts apart so the engine fits.
With the engine about 3/16 from front of the mount I still had to add some lead.
As for the throttle linkage it was about 1/4 in to short so I had to add a different rod.
I hope this helps!
Oh bye the way I did have to carve the needle valve hole on the fuselage as you can see in the pic and you will love this plane,it is a dream to fly and a lot of fun I had a 40 size engine in mine at first and didn't have the power for what I like, this .47 is PLENTY!
