Gary,

My Long Ranger is a TSK46 with an OS 46 engine in it. It is just a 30 size machine with a longer boom extension and pretty much the same size otherwise as a 30. The Funky 46 kit fits the Raptor just right from what I understand. I wouldn't hesitate to put in a 46 or 50 engine and you will really appreciate the extra power.

Even though it is thin fiberglass the fuse, paint, and accessories add a noticeable amount of weight. I have 2 other TSK 46s and it's like comparing sports cars to a 75 Caddy limo on performance. It flies heavy and sluggish. I had a few hard bouncy landing as it doesn't have the power in reserve coming down like most machines do.
