RE: Inverted Flatspin
I do mine like this. point the nose down with full left aile. After it spins two or three times add full down and full right rudder. Some planes will go into it right here. If it needs some help. Start adding throttle and moving the aile to the right. Every plane is different. Some like no aile some like full right aile. You will have to try different aile and throttle settings to find the sweet spot. Also the way I told you to start is more of a blender. I said it that way because the plane will go into the flat spin easier.You can start straight and level with the plane almost stalled. Some will go right in some wont. A word of CAUTION. Some planes will come right out of a flat spin some wont. Make sure you are plenty high. Lastly a rearward CG is a must. If you can't get it into one ease back the CG a liitle at a time.
