Spitfire Mk V throttle problem

[spreckair]

I was just flying the Spitfire Mk V and found that the throttle was not being responsive and was moving on its own.  This occurred during the Achtung Spitfire scripted campaign and in quick combat mode.  I switched to a Spitfire Mk IX in quick combat mode and did not have this problem; also, have not seen this problem with any other plane that I have flown.

I was just flying a Spitfire Mk V in the Achtung Spitfire scripted campaign and the throttle was not responding to inputs and was moving by itself.  I switched to Quick Combat and experienced the same problem with the Spitfire Mk V.  I then switched to a Spitfire Mk IX and could not replicate the problem.  Also, all other planes that I fly are working correctly.
