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


  55 mm

  1.485" OD

  Here is a web site that will do conversions inches to mm

  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 cm 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.

  Hey Paul,

  I'm pretty sure your dimensions are mislabeled.  1 inch = 25.4 MM by
  definition.  23.5 mm = 0.925 inches.  Are you really saying the
  dimension is less than 1 inch?

  Right Mark. It was centimetres. We got to the Moon on inches

  Boy, that was a lot of inches, one at a time:-))
