My quest balances at 165mm with a 5cell 6volt in the tank compartment with the throttle servo and the receiver towards the trailing edge of the wing,almost at the wing mount. I have the elevator servo in the stock location with a pull, pull and the rudder servo in the rear.

Question: It is balancing at neutral, meaning the nose is neither up or down it is straight and level. If I nudge it either way that is the way it will end up. Down pressure send the nose down all the way and also for upward. I have never encountered this, is it correct?
