Bigger isn't always better when your just starting out. The Tactic 650 is the best bang for the buck plus this radio will fly several transmitter ready planes from tower hobbies not to mention it also makes a great buddy box when teaching others down the road. I bought the latest Spektrum DX7 and other than the sticks being a little smoother it doesn't fly any different than the Tactic. The Spektrum has a lot of programing features such as mixing but  that's something a trainer shouldn't need. The more basic your setup is the better off you'll be until your a semi seasoned flyer. </p>
