I have been in this hobby for a few years now and I have all the equipment I need and then some. I presently fly an eagle II trainer with an OS 40 La on it that runs beautifully. I still have not soloed yet as this pass summer I could hardly fine the time to go out and fly my plane. I find now that it makes more sense to go with an OS engine as it will allow me more customizing options as in the exhaust dept. I just wanted some input on the Super Tiger engines thanks guys. Lou.
