a stupid idea
 

this is either an extremely STUPID idea or a good one. you know how jets use thrust vectoring to direct their thrust to do certain meneuvers. what i thought about is some how modifying a magic to let the firewall or engine mount move either up and down or make it to where it will move side to side. (can't think of how to make it move up/down and side/side both) yall think there is a way to do this? if there is that would be some ungodly harriers and flat spins and all kinds of other stuff.

well I would think that it could be done using servos to move the firewall like moving the controls on helicopters. It would take some doing to work out the problems with it but maybe it could work. Might need a gyro too.

There was a guy at one of my clubs who did that with a big stik .60 and four servos holding the firewall on a pivot point that went up/down and right/left. It would do some neat stuff, but he kept stripping out high torque servos and crashing the plane.

why not put some rudders close to the prop ?

You would be better off using a modified swash plate and heli like head system.

i figured there would be alot of doing that would go into it but if it kept stripping out high torque servos then i aint gonna do it then.

Some years ago I bolted a 3-inch metal hing between engine mount and firewall of an own-designed funfly-type model. The system created much amusement at the field when my flying pals at first thought the engine was about to "fall off" when I tested it with the enging running in the pits - they promptly named it an "engine-wobble system." It was servo-operated, giving varying side-thrust up to a maximum of around 20 degrees to starboard. The throttle lever was on the hinged side so the varying angles made very little difference to the throttle cable. The only thing I remember about flying with this system is that the model could knife-edge with the port wing down for as long as I wanted because the off-set thrust just held the model in knife-edge. All I had to do, after rotating the "engine-wobble's" switch, was adjust the engine speed to prevent the model climbing or diving. Once set correctly it would maintain its attitude and altitude without any "fiddling needed. Then I was free to concentrate on steering it around with the elevator - it was "so" easy to do. Knife-edge loops (from port-wing down only of course) could be made very tight real easy too. It was a lot of fun and it produced some amusing-looking effects on aerobatics too. Writing about it here makes me think I should try it again!
