gjeffers, Sorry, I didn't see your post of how you did it. I won't make you go through the agony of posting it again. But, do you still have a UCD?
Also, I noticed both you and raideron mentioned stalling engines at least to partial reason of crash. Just a thought to both you guys that may help. On the non pumped engines (Saitos) I always shim the fuel tank to slop approx 5 degrees toward the tail. Sometimes this seems odd but my theory is the clunk is in the back of the tank and when you get low on fuel you can have a pick up problem especially flying a little nose down (flat spin) and you have little forward speed. The fuel simply goes to the front of the tank because of gravity and nothing for the clunk to pick up. But if you slope the tank to the rear of the plane, this helps keep the fuel to the back of the tank. Also, another thought, you could just land a little sooner?!?!?!? Anyways, that has helped me experience less in flight stalls.
Thanks,
Barry
