hey, well i was just checking over my heli, and i found out that i managed to miss 2 collars (d3xD4xL4) on my raptor 30 pitch control arm.

Ive looked all over midland helicopters site and i cant seem to be able to find the collars? does anyone know where they are sold, or if midland helicopters do them??

Do you mean the sleeves that go over the bolts?
If so, you can make them from brass tubing, carefully cut to the proper length. Most hobby shops and hardware stores sell K&S tubing in short lengths.

ive just figured i actually have 2 spare collars, BUT they are 2mm too long (from old washout base)

Any ideas on how to shorten them down a bit without damaging them?

If you can put a bolt through the collar and fit a nut to clamp it up, you can the put this assembly in a drill. Fix the drill firmly and turn on and use a hacksaw to do the cutting at the right point. This will ensure the cutoff is straight across. You may need to file a little to square it off.

Webhost, it's VERY easy to make your own spacers. I'm all for getting the right parts, but we're talking about a silly spacer here. I'm in the same boat as you right now, I'm trying to get 2 Raptors build by this weekend, and I had to make a few of them. Only takes a few moments. I use a mitre box and a razor saw to cut the brass tubing. Try to cut it a mm or so long, then use a file to get the exact length.

Hiya, midland is shut tomorrow, try skyline helis, they're pretty quick. I understand your urgency and would strongly advise making your own up out of brass tube which you can get from most model shops. Am I correct in thinking these are the pivot points for the pitch control arm ?.

Are you talking about BK0076 and BK0078 or BK0076?

Whatever you have got, cut/file it down to size right now. It will be OK.

DON'T PANIC, Sunday is just 5 days away !

im travelling to midland heli's on thursday. BK0078. IF midlands dont have a pitch arm set ill squeal at them and ask WHY NOT! lol then ill remember what you said and ask them if they have any brass tube.

I did try cutting one down that was 2 MM too big, but it went horribly wrong.

I see that nobody has heard of a tubing cutter.


Are you on the list?

to shorten them, sand them using fine sandpaper. Move the part in a figure-8 pattern rotating it occasionally. This will result in a nice square end

keepin' it real
