Well fella's, I swore I'd never come back to helicopters, but alass..... I was sucked in again. Last year I went completely electric, and gave up all things gas. Aftre burying $2000 worth of high-end futaba/fury equipment in an unfortunate crash related fire, I gave up heli's for Good. Last week, I was at the LHS store and they had a trex sitting on the counter. 45 minutes later, I owned one. Over the last week, I have been on this sight quite a bit readng about all the mods you guys have come up with. I have to tell you how fantastic the brain-trust is in this group. I have some shots of my new trex, but I have 1 problem left to sort out. I need to know how to make a better anti-rotation guide for the CCPM swash. I tried to bash one together from plastic, but it is less than perfect. what have you guys done to insure create/rig an anti-rotation guide for your cccpm coversion heli's?

if you have a box of spare feathering shafts lying around, take two countersinking screws from the mechanical mixing hardware you got rid of when you converted to eCCPM along with two of the longer brass inserts and mount two feathering shafts to a flat piece of plastic left over from the frame. screw this to the top of your sero carrier. chop the spindles down to size if you want to or if you are a bit tail heavy leave them to fix COG.

by the way.....
Since R/C heli's are roughly equivilent in cost to a crack addiction, and since they are infinately more fun to share with friends, is there anyone flying a trex in the Northern Virginia area?

I've just used a brass strip from the hobby shop. It works just fine and looks pretty nice.

JJsaratogaNY, Funny you should mention using Hummingbird parts. My eccpm frame is almost done. Using the 120 degree mast from my old C.P. hummer. Bored out the center, shaved the top and bottom and it fits nicely between the main bearings. Will put up some pics monday. The anti-rotation bar is too short to get full pitch though. Will have to make one. I like AnnihilaT`s idea with the feathering shafts.

How did THAT get in there?

My anti-rotation plate is made from 1/16th inch birch aircraft ply.

The anti-rotation pin is made from a 2-56 pan-head machine screw and one of the spare long aluminum bushings supplied in the Trex kit.

I ran 2-56 tap through the aluminum bushing, then threaded the bushing onto the screw. I then took a Dremel cutoff wheel and ground the head of the screw down to be the same diameter as the bushing. Finally, I ran my 2-56 tap through the lug on the swashplate, then screwed the screw into the swash. I locked it down with a shot of CA on the screw, on the back side of the swash lug. I used the cutoff tool to cut the screw to the correct length.

There are more conversion pics in my gallery.
