OK, everything went well, thanks for your input every one. " got started from the first flip, what an engine!! "
Came to the engine installation point and i reached to a dead end!!
On the manual of my SU31 made by black horse models
http://www.americanpioneerhobbies.com/sukhoi120.html, they've installed an OS 160 at a 45 degrees angel. The Q. is,
could I install my MVVS 1.6 upright or inverted instead, since i have a pitts type muffler "insinde the cowl"?
Appreciate the input.
Regards
Moe
