Just finished putting together a Venus and mounted the engine 4 15/16 in from the firewall just as the intructions state,I have yet to fly the plane, but I see in the new M.A.N. that the engine should be 4 1/2 in from the firewall. Outside of making an adjustment for a more nose heavy plane how will this affect the flight performance? I really don't want to remount the engine at this point since It's ready to fly.



Thanks

As long as your CG comes out to where it's supposed to, and the cowl fits, I wouldn't think it would make any difference.

Did you check the CG?

I also have a Venus that I'm building. I went with an OS FS-70. What are you using? Let us know how it flies.

will a o.s. LA 65 fit????
