has anyone ever thought of making a plane that allready flies well have negative stability to increase manuverability. you could calm the plane down with a gyro so that it flies like a normal plane then when manuvering it is crazy. i might try this with my mig 29v1, any thoughts would be apreciated.

Why, yes!

And you can add in a gyro too.

This is a common trick with real jets.
They're tail heavy with gyro and computer controlled stabilization.
Tail heavy is inherently unstable and should only be tried by seasoned pilots. This makes the jet very reactive to the point of being squirrelly. The nose will pop up very easy. If the center of balance is way tail heavy, you're all over the sky, hoping you can land it without crashing.

cool gonna outfit my mig with the 3 axis gyro and try it out. first a little tail heavy moving more and more until it is as manuverable as i want.

Well, you really need a plane with canards to do that safely. You need cg to be aerodynamically moved forward (squishy used the proper word) for it to fly. A parkjet without the help of canards will most likely not reach aerodynamic stability before an unplanned landing changes the aerodynamics for good! But, the fun is in the testing!

I tested my RCP F-22 with my new Guardian 2D/3D Inertial Stabilizer from Eagle Tree Systems. it worked amazingly well as long as I had it turned on ... as Luke says, with the CG so far back, it becomes a challenge to fly without a stabilizer. I prefer to have control even without help. But it was a fun thing to properly move back CoG when there is technology available. Attention! Big difference between Eagle Tree Guardian and cheap orange stuff from HK...

yeah the reason i am chosing the mig is that it is the airframe 2 years old and starting to fail in numerous places so if it crashes, no big deal. i know the orane rx gyro is very cheap but it is all that i have and it works to my knowledge.

oh i am so amped right now! it worked! i set the cg back on the mig v1 about a half inch back( i know, it sounds small) and the difference was night and day. i had the gyro control on a switch so i could feel the difference when flying and what a difference it was. the only problem was i did not have my battery secure enough during flips so it tore out and i got a pendulum effect a couple of times. i am gonna make all of my planes this way now it was so effective. if you guys out there have a gyro i would suggest using it for this, it is worth it.

I did that without a gyro, how do you think I made that "fly it like you stole it" video? It's super fun, just make sure you build the airplane for the rigors of what you're doing. I had a lengthy build thread detailing what I did to mine. oh, and I also shortened the length of the whole airplane about 1.5 inches..

very true, very true. this weekend i am gonna move the cg back even further and see how fast it will really flip around. and squishy i opted to put the gyro because i wanted it to be stable in slower flight also and not just for the aerobatics.
