How much should the engine mount flex? The engine mount on my DPM Ultimate 40 can be flexed about 1/16" in up and down measured at the nose cone. I know this isn't much, but I don't recall any of my others moving this much, nor as easily.

By up and down I mean the head is moving fore and aft. The engine is mounted on it's side to the right, so the movement is really sideways to the airframe, but it cannot be flexed at all the other way. The firewall is not moving. The arms of the engine mount are definitely flexing a bit. The plane has not yet even flown. I have finally gotten a smooth reliable idle under 3k rpm after 2/3 gallon. It's ready to fly other the engine mount concern.


TIA
