Huges 500 with OS37

[Gasser Steve]

Thinking of getting the Funkey 50 size jet ranger. I have a Hawk mechanics with an OS37 in it. Has anyone tried this combination? Is there enough power? Or should i just get a 50 size engine and mechanics

I have a TT MD500E on a Raptor 50, and live/fly at 5000ft. An OS 37 wouldn't fly here...

You may get away with it at sea level, but it would be marginal. I'd go with the 50 mechs if you're going to run a 50 size fuse...
