The Tower Trainer .40 MkII ARF is a wonderful airframe. The GMS .47 is a very powerful engine, it will require a little extra run time before it breaks in, but you will be rewarded with tremedous power and instant throttle response.

I just hope you remembered to order a radio system w/ servos if you didn't get the RTF version of the Tower Trainer. Your reference to the GMS engine rather than the Tower Hobbies .46 led me to believe you've ordered seperate components.

Congratulations on your excellent choices for engine and airframe!
