 I just received the new plate mount from Jeff this morning, and it is
 very
 impressive. You have to hold it in your hands to really appreciate its
 lightness compared to the original adapter plate.

 Add in the fact that it is also the engine mount, and will accept
 whatever
 starter you have, wow! If you are going with a TC PSRU, this is the
 way to
 go. Truly amazing.

 Those "cups", are they replacements for the stock engine mounts?

 Yes. Most people don't use the stock mounts. They are very heavy
 and the 900 foot pound torque from the 3 rotor prop must be reacted by
 the mounts so putting them on the PSRU adapter plate mount is the best
 place.

 We use the low cost (under $10) Barry Controls 2200 series industrial
 rubber
 bushings. This is the same mount used in the TIO 550 Questair Venture.
 Lycoming rubber bushings are $100 each.

 How much does it weight compared to Tracy's stock plate?

 Brian Trubee

 I don't know exactly but I think it is a couple of pounds lighter.

 Jeff have you weighed the plate?

 Paul Lamar


 Paul
 Tracy's plate weighs a little over 8 pounds, mine weighs about 5 1/2
lbs.
 Don't forget my plate has a larger frontal surface area.
 If Tracy's were the same over all size it would weigh at least 10 lbs
 maybe more.
