Frist Try

​Here is the general layout of collective 1. Trying to make all of this by hand and Dremel  pretty much broke me down into getting my machines! Now I wish I had bought them 10 years ago! The mainshaft is slotted and a washout unit that I made runs the collective. Its a scaled down version of a Kyosho model. Its not worth the hassle, go CCPM!! Keep it simple.

Here is the washout unit I made, this was the second version as the first was out of plastic. Man I love these machines already! It was never used but is on "display" as one of my first parts hehhee :)  5-31-00

CCPM Flybarless

Picture
Here is the beginning of the CCPM. A new layout for the servos taking into account pushrod placement and weight distribution. Its made out of plywood just like the original and cut on a Dremel scroll saw. 7-11-00

​Here is a picture of the servo layout with gyro placement.  Looking good :)

I then made a new lower portion for the swashplate. I used the existing LMH top part. You will need to do something as the kits swash is not make to pivot. Also consider 90 CCPM (see the 3 pics).

​I turned an eyelet for the tail and got rid of the mechanical gyro. If you love the LMH, get a piezo gyro for it, you won't ever go back! You can now buy this same piece I made for around $7 through Lite Machines. Its worth it, or make your own.

Here is the main head. I cut the blade holders in half and stuck a bolt through it. I used a piece of fuel tubing as a cushion but I don't think its needed do to the blade flexure. Currently I am using a 3 mm bolt with locking nut. Use the 4 degree blade holders.

Here is the right side of the heli with new gas tank placement. I bought a back-plate pressure thingy for the engine and have a normal chunk style tank for those inverted flights :)

Here is a picture of it flying. No, the tail slide was not meant but I later found the elevator servo had one chipped tooth. Made for an interesting flight hehehe!

Here is the most current version. Its pretty stable, and I was able to land it on all 3 takeoffs. Its getting there. Make sure you grind flats and grind the setscrews flat for maximum hold. Use blue loctite. 7-8-02

Here is another view. Note that I am using a anti-rotation for the swashplate from the existing LMH piece. Also, you will need a anti-rotation for the entire swashplate which is simply made out of wood here.

I think the design and experimentation on this project is coming to an end. Sadly, I am "burned out" with this particular project, engine and general design.

 No more work will be done on the LMH as far as I can tell :) It is in a little box right now.

​To make a good flybarless design you need a stiffer head (teetering) and weighted blades are a must!
