Landawg131,

If your getting the RTF version all you have to do is unplug the AFS. You don't need to remove the sensor because that will leave a hole in the bottom of the fuselage. I learned on one and now I'm about to train my son. I think it is a great flying trainer. If you get the RTF version and take all the stuff off be sure you put a lot of up elevator trim in it because without the speed brakes off it you will try to go up and it just won't go. It will take off with ground effect and then come back down unless you hold the stick all the way back just to keep level flight.
