Hi Paul, I am interested in your Rotary engine mount adapter
plate. I have 13B Rotary Renesis Engine (2004) and a Tracy Crook's
RD1C PSRU.

What is the length (in milimeters Please) between the two engine
mount fixation bolts ? I have to Check this regarding to the
firewall fixations of the engine mount. What is the reference of
the center axis seal? Thank you Regards. Philippe Izard

Thank you Paul. It should be 550 mm : about 21 1/2 inches ? Is that
right ? Please, if it is right, I want to know now the length between
the central axis and the right fixation bolt on the engine mount, and
the same for the left side. So I can check  if it will fit with the
central fixations of my firewall. Best regards Philippe


23.5 mm from the right side from the pilots view.

It is asymmetrical for several reason. Keeps the motor mount tubes
away from the hot exhaust and allows mounting a heat exchanger vertically on
the right side the cool side of the engine.

Here is a picture of Tracy Crook's 3 rotor powered RV8.

Our universal motor mount will fit all firewall configurations and is totally adjustable.
