I have owned the .40 GP 182 and it flies extremely well. It tracks well on the ground also. I had a .46FX and it was enough power for it. The plane is build pretty light. it stall really well, in some situation it will tip stall but on slightly and it's recoverable. other than that it stalls without any heading deviation. I made sure that it was laterally balanced also and it helped prevent major tip stalls. I did however change the nose gear and went with a Fults dual strut steerable nose gear. the one that GP offers is pretty weak. On my first landing the nose gear bent back. It is very fast on landing so I had to cut the throttle on the downwind leg of the approach. I have head of people doing modifications so that it will have flaps. I didn't do this to mine but I know it can be done, also it's easier to install the flaps before the wings are glued together. There is plenty of room inside the cabin. It looks really good in the air also.
