All of this is done for "pure love of the hobby!" Its about Sharing :)
| :: Time Project began: 3-29-00 :: 1st Collective Flight date: 4-00 :: CCPM Flight date: 6-9-02! The LMH flew! Man it was unstable and all over the place but it lifted! Its surprising how little input you need on a flybarless system. It crashed 3 times and finally stripped a servo. Gonna add some wheel collars for stability and need to get some new gears, check back soon for updates! :: CCPM flight: 7-8-02 The lmh is acting much better with the wheel collars. I landed all 3 short flight. Still need to work a little more on the stability part. :: LMH has been retired as of this time. |
FIRST TRY 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 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 :) |

FLYBARLESS
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. |
Here is a picture of the servo layout with gyro placement.
Looking good :) |
Swashplate Overview |
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 left side of the heli. Fully redone. |
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. |
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! Check out my ECO 8 Goes Flybarless Page for my
next flybarless attempts! |
