Yep a big one, REDUCEYOURRATES! Ihave mine set to 50 and an expo on the elevator at +30. I kept the rudder at full rate. This plane has a rather large elevator which can quickly put this plane into a vertical on take off. At full rate it will do a 10' loop. Mine has the metal case motor, but the prop shaft came loose, something to check. Ihave the same issue with grass takeoffs, landings arent too bad, as long as the prop has stopped by the time it touches down. Iset the brake on the ESC. Take offs though, if the prop catches grass, it will pull the plane into the ground due to the down pitch of the motor.

I dont know what Ican use though to clean the grass stains off the plane without harming the foam. Ididnt want to modify anything on the plane, so Im putting on a 3" nose wheel and 2 1/2" mains, and will see how she does, that 1/2' difference in nose wheel that Ihave on now may make up the difference. Iam also considering a smaller prop once I determine the pitch.

Reason I set expo on the elevator is that Ifound that it can pitch up quickly with just the slightest touch on the up, usually when I am bringing it around for a flyby or landing it would pitch up when leveling off, it was very sensitive to pitch, adding the expo smoothed out the stick center and now she flies great. My last landing was picture perfect, came in over the soybeans, my friend was sure I would nail them, but I didn't, it flared out nicely, where I had problems before, Iusually stalled it here, and it touched down gently and rolled about 2 feet.

The previous landing before this was a disaster. Ijust couldnt get it down to the ground where I wanted it to be, and it just floated past the barn where the cross wind caught it, hit that big tail on it and pointed the nose right at us, so between trying to straighten it out and land at the same time Icaught a clump of grass and spun it around on its wing and tail tips. Munched the trailing edge of the left wing and wrinkled the tail feathers. I had to make some large trim adjustments on the next flight due to the elevator now being warped, but after that she flew great. So two minor haphazard landings out of 7 flights, and the plane is holding up great.
