The Thunder Tiger Trainer 40 that is shown in the pictures is not the same as the one that Ken posted the link for. The one pictured is the original model. I have one of those and it is still in flying condition after about 15 years. The original had a cowling and the upper half of the fuselage was plastic. I believe the engine is a Thunder Tiger GP40 or possibly a GP42 is it is a newer model. It is a great flying trainer and is very well built.
