Hey fellow RC'ers!
I am in need of some help. I have RealFlight G2 and I am trying to get one of the airplanes to flat spin. I have seen a couple of guys do this at the field and it looks wonderful. I just don't have the cajones to do it with a real (model) airplane. Can anyone give me suggestions as to control input, etc. or a book perhaps that describes control inputs required?

From: gone,
While learning to flat spin... SLOWLY move the ailerons. often you need less then 1/3 of full opposing direction. Excess aileron can snap you into an opposing directionspin, or snap you into a dive. You can't reverse the ailerons too slowly (except you can run out of altitude...)
When learning to recover... plan on 4 rotations of normal spin on getting out of the flat spin. (If you allow that much room... you should have plenty of time to recover) Remember... the normal spin loses altitude much faster than the flat spin.
With enough power you can climb in a flat spin. You won't ever see a full scale do it... but I have seen models do it.
If CG is back far enough for flat spin to work... and the engine dies... its going to hit the ground.

CS, I also have the real flight G-2. I can flat spin every model I own. However I cant get anything to flat spin on Real Flight.
I wish I could tell you the trick. The planes on the G-2 seam to fly through the spin and never really stall out. Except when I am going into a hover at 3'. Then they stall all the time. Just practice at 500' with your model. It's not hard to get out of one. It's a lot harder to get a plane onto one.
There are some great flyers in your area. I know some of them would be glad to help you at the field. Torks, Westside and Baxter have people that can help you.

I agree with Dave that G2 does not allow a good flat spin. But, I have had some luck with the AT-6 (of all planes!) in various configurations. It flat spins the best inverted. The trick with it is to really get it spinning FAST and then slowly cross control the ailerons. It rotates around its central axis. There are some others that flat for a little while, but not like the AT-6. It is even hard to get out of the spin if you are too low. Good Luck.

You shouldn't just arbitrarily go to full opposite aileron. Many planes with wide and powerful ailerons will roll out of the flat spin at full opposite. Get into the normal spin and go to full power. Then ease the aileron over watching the plane. You should see the wings leveling out and the nose raise. Find the amount you can take without kicking out of the spin and stop there.
Many planes won't get really flat, but they will enter a "flat spin mode" with the wings more level and the nose higher than in a regular spin.

The problem with the stock G2 planes is the CG is to far forward to flat spin properly. You can download some custom planes from http://www.realflight.com/swap that will spin anyway you want to. One thing you need to keep in mind... After you enter the spin add a few clicks of power... If you don't it can be very hard to get out of the spin! Also practice all spins from a very high altitude. I find one of the easiest spins for me to get into and get out of is a knife edge flat spin… Try this get very high flying level at about ½ power… Then cut power and add full down elevator, full left rudder and aileron. The plane will do an inverted snap and then fall into a KE spin, hold these inputs for about three rotations add a few clicks of power then when you are ready neutralize the controls and recover. A cool twist to this is to cross the ailerons to the right and then move them back to center slowly and enter an inverted flat spin. Remember a when in a KE spin the plane will fall very fast so have plenty of altitude to play with!
Good Luck!

Dave, I setup the downloadable CAP for RF Deluxe with the CG so far back it barely flew and it wouldn't flatspin

I have one I downloaded called "CAP232TOC Best" and it will Flatspin or just about anything else you want it to do... This is for RealFlight G2 not Deluxe... Email me and I will send it to you if you have G2

Planes with lots of control surface area are relatively easy to get flat. It does take some finesse when using aileron. Rolling into the opposite direction occurs frequently.
Planes with scale sized control surfaces sometimes prove the foresight of building the garbage bag into the airplane. Makes carrying the parts back to the pits easier!
