I fix the problem, The problem was the air file, this air file was the IS4G, I put the original and the model run OK.
Is ugly fly with the original air, for this reason in the V2 ,I put the IS4G, but it has the engine problem.
So I have to go back to the original, could someone create one using the original but with the IS4G parameters?,
or improve the original in some way that the plane does not pitch?.
We have a perfect model thank to The b-24guy, only need a air file.
