I was considering switching to a servo heater valve, but it would be nice to do a servo on the heater door too. Has anyone adapted the servo in a valve to a push rod that could control the door? Gets rid of those Morse cables and stiff knobs.

............... and the fresh air vent door should the roller assembly be absent. I think that Herb Adler was looking at something along these lines some time back.

I was thinking of the internal door. Spruce Aircraft has a kit, but over $200. I was wondering if a heater valve could be cut off and a lever welded on, but force is an issue. Not sure model airplane servos have the force.

Scott,
If you mean the door at the bottom of the heater assembly, I've done it. I used a 9 gram servo motor from evil bay as well as a servo tester and a 5V UBEC ( universal battery eliminator circuit). The UBEC will step down voltage from a 6S LiPo for a RC airplane down to 5V volts for the servo (6S is 22 volts). I up graded my heater with the bigger core and a three speed fan motor, I was also going to do the servo water valve, I have it I just haven't installed it yet. Other domestic things got in the way. I'll take some photos of the door servo and post them.

Just what I was thinking. I'll await the pix, "servo tester" I gather would be the controller. I'll do some googling.

When I was playing around with using remote locking motors to operate the flaps and central door flap, I think it was you who suggested lawn mower accelerator handle and cable. It would need some lever design to get the correct angles.
