I have been thinking of converting my Align Trex 450 to a nitro heli. But Im not sure what kind of snags I could run in to. I don’t want to try and make an advance flying machine. I only want to do scale flying, no 3D stuff
Please help

If you mean to install a nitro engine on a 450 the result simply would not be worth the effort.

The size of the engine that you would have to put in would need to be less than .15

From my experience, those really tiny IC engines are very loud, anoying, and all around unreliable.

Look this over, I don't have one or know who does but is tempting

We have one at our field, its nickname is the Pigasus. About the best thing to be said for it is that it flys.
