ok i have 2 planes Nexstar select .46 and a Hobbico Avistar. My question is this Can i take the o.s .46 from my nexstar select and put it in my avistar.

this ist the engine that tower recommends for my avistar http://www3.towerhobbies.com/cgi-bin...?&I=LXFMD5&P=M

and this is the engine in the select.

Engine: Pre-installed O.S. Max .46FXi (7.5cc) with High-Speed
Needle Valve extender/limiter that limits the movement of the
High-Speed Needle to prevent engine from being run too lean.
Engine is mounted on IsoSmooth Mount to isolate airframe and
radio gear from damaging vibration

on my avistar since its a slightly smaller plane I would change Props to the avistar Prop Correct?

yes you can use the engine and same prop. the prop helps control the rpm of the engine but in most cases you could go up or down 1 size.
