Greetings,

 

The Dominator gyro is on order, to arrive around the first part of April (I hope).  The gear drive is still on order from Autoflight, and hopefully, will be shipping soon.  All I can do in the mean time is get the engine as ready as possible, which mostly means making a new engine mount plate of some type.  

 

Question one- If I were to make a sandwiched plate, similar to what CCI does (did ?) with their mounts, how thick would it need to be for a single rotor?  The CCI plate was 1/2" thick for the two rotor, and I made my first single rotor mount that thick as well.  Since I'd like to reduce some weight, I'm wondering what I can cut this down to.  I'm guessing 3/8" at least, and maybe 1/4".   Any suggestions?

 

Second question, how much oil bypasses the primary regulator (in the front cover) under normal operation?  Does any bypass at all?  I know it's there primarily to prevent overpressure of the oil cooler in case the lines get blocked, but I wonder if it's actually needed for normal operation.  In other words, can I plug up the primary regulator, and be OK as long as nothing in the oil lines gets plugged up?  

 

Thanks,

Rusty,

I like the mount plate for simplicity - however it does move, and move enough to get leaks. Since this is a perceived problem with the 2 rotor, I would leave it 1/2" for the one rotor, with the required internal holes.

Just my opinion Matey!
