Tom,

If you don't want to spend the money on a 4 stroke, we understand. They are expensive.
So if you do go with the 2 stroke I would agree with most of the other people here that a plain bushing engine like the OS.40 or the TT GP.42 would be a good choice.
BTW Tower Hobbies is now offering $25.00 off of an order of $199.00 or more.
