Any suggestions for a good 40 size ARF??
The Thunder Tiger Stick is an excellent second plane. I have one that I have flown for several years. After a couple of tangles with some bushes, the covering looked ragged so I stripped it off. I was surprised at the quality of the construction compared to other ARFs that I have seen. I was ready to reglue all the joints and only found one minor spot on a rib that needed touch-up.
It is an excellent performer with a Thunder Tiger Pro46 on it. Everyone in our club who has flown it has been surprised at the performance. The one thing that amazed me the most about it was that it is actually easier to land that the trainer that I have.
