Can anyone help me with the best way to get out of an inverted flat spin? I can do them fine with any foamy, but got into trouble with my mini edge today. Being this plane has an airfoil, it is totally different in this move. Going in is no problem and the plane does the trick great but when I went to pull out, none of the controlls respended. I finnally got the plane out at around 10-15 feet off the ground(and that was from at least 100' up!) by giving full throttle and down elevator(the plane was inverted). It was very slow to respond, but finally pulled out.

BTW, I've been flying RC for well over ten years now but just got into the 3D stuff and electrics around 10 months ago. The ME is my first electric 3D plane with an airfoil.

I add full up elevator, full left rudder and full throttle.

I try to give myself enough altitude so I can point the nose straight down and do a couple of spirals, this gets the airspeed back up and lets you control the exit better. Looks good too.

Yea, nose down, 1 aileron roll and exit in the flight pattern direction. Very smooth looking.

AHHHHH....welcome to aerodynamics theory applied while in flight.

Flat spins both right side up and inverted can be difficult to recover from in certain types of aircraft, and impossible in others.

Here are the proper steps for flat spin recovery.

Remember the acronym P.A.R.E.

Power - reduce power to "idle"
Ailerons - return ailerons to neutral
Rudder - Apply full rudder opposite to direction of spin
Elevator - return to neutral

If your in a left spin, with a right turning propeller, adding full power will flatten the spin due to gyroscopic effect - this means the nose will raise up. If the nose gets higher than the tail in the spin....kiss the plane good-bye, because its gonna be real hard to recover from if not impossible.

Same thing for a right spin with a left turning propellor.

Once your spin has stopped, reduce the rudder input, and adjust elevator so that the plane exits in level flight. Then increase power to fly out.


Here is a good video of a full-scale extra 300 inverted flatspin and recovery using PARE

I had a problem with that plane recovering from anything very well. I don't have it anymore!

This isnt excusively a problem with flat spins, some planes require a nudge of down(up if inverted) ele to unsettle them from a normal spin. Did you try full opposite rudder?

Thanks for all the tips everybody. I can now get the both inverted and upright with no problems at all. I just needed to get a good feel for the airplane.

Here's my standard answer to recovering from just about everything, more power. With enough power you can yank a plane out of anything I have gotten them into the last 17 years. I tend to run double the recommended engines, the only exception being the new 3D designs for which the recommended power is often enough.

I have never had a flat spin that I couldn't get out of with a touch of opposite rudder and full power.

Another good idea out of an inverted flat spin is into an outside snap. Doesnt look good but works, just switch the ailerons and gun the throttle
