A Thunder Tiger Pro .36 is a nice, powerful engine. It should be able to produce power similar to the .46 LA you have on your Cherokee ARF. You can use it on most any .40-size ARF that doesn't require a heavy engine to balance the plane. It is similar in weight to the .40 LA/.46 LA and will work well on most any airframe that works well with those engines.

Pair your TT Pro .36 with a 9x7 prop for speed or a 10x5/10x6 prop for sport flying, and you could enjoy it on the nose of a:
