You are flying a pretty good second plane right now. The Avistar can be turned into a serious hot rod that can entertain you & keep teaching you.

Remove the dihedral, & clip the wings by ~ 2" each side.

Convert to a tail dragger.

Install a BB .46, like a TT .46 Pro, with an APC 11-6.

Crank up the control throws.

Launch it & Hang on tight.

This will save you a bunch of $ and still let you have a blast while you are deciding on which direction you want to take your RC flying career.
