Hey guys
I have a Great planes Super Sportster. Can i make it flat spin?
If i can...How do i get it to do it and how do i get out of the spin???
Hope somebody can help!

1. Enter a conventional upright spin with a lot of altitude. (Make SURE it is spinning and not doing a spiral dive.)
2. Slowly reverse the ailerons (direction). This may take all aileron control out or reverse.
3. If this doesn't work you will need to move the CG aft. Do this a little at a time. If you go too far and get the plane in a flat spin too deeply it might not recover.
4. To recover release all control inputs. If it still is not recovering add opposite rudder and then add power.
5. Elevator throw needs to be more than normal in most cases.

I dont know how in the world I did it... but today I was screwing around, absolutly zero wind, and somehow got into an inverted PANCAKE FLAT flat spin twice! I was flying my 4*60. I was doing snaprolls, full right aleron and rudder w/ full up elevator and then changing the elevator to full down. This made the plane do a neat tail over nose once or twice... it was pretty fun... but two times... I got it to do this absolutly pancake flat inverted spin... it was the coolest thing I've seen! the first rotated 5 times and the seccond rotated 7 times. Does this happen just by chance??? Or is there a certain set of key movements to make this happen again... it sure was good lookin!

snaught,
When you input for negative "g" forces the rudder reverses. Most likely what happened is you input down elevator with ailerons and rudder in the same direction which is the transition for an inverted flat spin. Then changing the elevator to down puts it into a knife edge spin. This makes for great fun when you change from one to another kind of spin.
To better understand what happens with the rudder try this:
1. Place the plane in a stand inverted. Stand behind the plane to observe the control inputs.
2. Input down elevator / left ailerons / left rudder
Observe the elevator is "Up"
the rudder is "Right"
the wing on your left has the aileron "Up" (so roll is
still to the left)
3. To correct the above "negative g" just reverse the rudder (in
the case above use right rudder which will move it to your left)
Additional control input information:
Positive spin or snap roll: Up elevator and ailerons/rudder in the same direction.
Negative spin or snap roll: Down elevator and ailerons/rudder in OPPOSITE directions.
The above information is given as a basis for learning these maneuvers. There is much more information regarding this (literally volumes). Start with this and keep looking in here at RC Universe.

Super Sportsters have been known to get "stuck" in inverted flat spins with an aft CG. Be on the reverse rudder just after centering the sticks for recovery.
Upright spin: Fly straight up to a huge altitude. Stop the plane on an upline by reducing throttle. When if falls backwards, put both sticks in the bottom same (right or left) corners. After a revolution or 2 slowly reverse the aileron and add a click or 2 of power at the same time.
Inverted spin. All the same but use down elevator.
Again, be on the reverse rudder and power just after centering the sticks incase it gets "stuck". I've flown for only 5 years and have already seen (with my own eyes) two Super Sportsters go in on their backs, because the pilot did not know how to stop the spin.
After you've done it several times, start to experiment with moving the sticks around. What happens if you start the spin, then, without changing the ailerons, add 3 or 4 clicks of power. After that throw the rudder opposite and hold the power. Start real high with that one!

One day at the field I made a low pass and pulled up into a 60 deg clime. Did an out side snap. I have done a hundred times, but It looked so great I held on for one more revelotion and thats all she wrote. Not enough altitude to pull it out. She did a slow spinning spat right in the middle of the field.

What snaught did was a lomcevak. Most of the time when it is done correctly (timing) it will end up in an inverted flat spin that is very flat. I have been doing this with my kyosho 40 Sukhoi and it is a blast...... Spectators just love it as well....

Yep, It looks very good. You just need sufficient altitude with a plane like my Hots. Even in a upright spin it takes a while to recover. And if it spins fast enough you have to throttle out of it.
