New Throttle - WAS - Tonight's Dumb Idea...

[Bob Pastorello]

What looks to be the "firewall" is actually the rear plate of the motor mount.  THAT plate is soft-mounted to the real firewall using the rubber washers/well nut method that Lee Davis shows on the Piedmont website, and many are using.  Mine is an adaptation, intended to move the anchor points for the "soft mount" to the extreme edges.  Look here, Roberto

Toward the bottom are detail photos of the ply plate, and how it is isolated from the actual firewall.

  Hi Bob,

  I saw the pictures of your servo arrangement.
  My opinion is that such installation is not so good, because the servo is not connected to the engine DIRECTLY, but to the engine mount.
  Being a fixed installation (not soft mounted), there is a relative motion among the engine (that wants to rotate) and the engine mount (that is secured firmly to the firewall). In this way you cannot say that the servo is connected to the engine.
  I don't know if this way is safe or not, but of course it is WAY less safe and precise than the servo connected to a soft mounted engine.
  I supposed that you was referring to an Hyde mounted engine. On your installation, my advices are not appliable.

  Best Regards

      Okay - since you've opened it, read on :)

      Thinking of mounting an adequately-sized micro/mini servo directly to the beams of a motor mount to control my OS 1.60 on my experimental Arresti III....

      Anyone ever done this?
