Then you could put in a sound system to sound like a real engine.

Ifly Magnum, OS, and Saito four strokes, from a 45 saito to a 180 Saito. All are fine. The best value for your dollar is the Magnum. It weighs a little more that the O.S. and Saito, but dollar wise it is a very good buy. Or, you can go off shore, IEHobby King and get an ASP, which is a Magnum with a differen badge. Shipping is a hit, both from the cost and the length of time. Also you are basicly giving up any customer service going that route. The price almost makes up for that loss though. Hobby People gives good service on the Magnum, Tower on the O.S. and Horizon on the Saito. Your choice.
