i just got a tf cessna 182 gold edtion with cockpit kit and plan on making it a scale plane but here is my question i'm at about 4500' and i would like to know what engine i should use perferable 2stroke to hide in the cowel with out having any thing sticking out of the cowl???????

The Super Tiger .90 will do you nicely. And it should fit inside the cowl fairly well. I've seen a fellow club members with a ST .90 that had more then adequate power.You may look at the MVVS .90 as well. It's just a bit taller the there .60 and if it runs as well as my .77 it should work very well also.

what about themixture needle sticking out thats the problem i'm facing right now i'm leaning towards a sato 120 mounthed inverted

My three cents, I have built three planes with the older Italian S/T's and have not been able to get anyone of them to run correctly inverted (lot's of dead stick's). I live at 5000' have an OS 90 FS inverted in it, run's absolutely beautifully. If you look at the opening you must have for the exhaust for the S/T inverted it is probably more than the head opening you need for the OS90. You can twist the exhaust on the OS so it requires very little opening.

Doug, If you can get a S/T to run inverted, would seriously like to know how? Iv'e had no luck. Any Info would be appreciated. Thanks
