I am getting ready to mount the engine on my roo. I am using the mount from jet cat. I am just going to set it up "0-0" Is this correct?? Also should I be worried about the fore aft measurement??? How far the tail pipe is from the end of the fuse? Thanks for all the help

PS The engine is a jet cat p-120

Just center the mount, or engine can, on the surface. A little for or aft is not critical. Set the mount level on the Roo, but put shims under the back of the engine at the end to raise it 1/16". This is a good starting place from which you work to get the ideal setup. Don't forget the 1/8 " reflex in the elevon when you set up the radio.

How tight should be screws be on the jetcat mount (purple) for the p120? Mine is setup in a way where the clamps DO NOT touch each other...they are quite a distance apart.
