LMH Pilots - Collective Question

Post by KFG » Sat, 11 Mar 2000 04:00:00



Hi Folks,

I have my LMH 110 almost all ready to go. Quick question for the group:

My collective seems a little tight. It moves smoothly, but does have
some
resistance. I have isolated this to the plastic ball link connections,
as the rest of the assembly moves very freely. The resistance is not
great, and the servos move it easily (though on return to neutral I do
get a little hum from them).

I'm reluctant to try to loosen the balls up by "sanding" them because I
know I'll go to far and end up needing a new lower swash.

How much resistance is OK? Will it break in? Will the hum hurt my
servos? I'm running micros with about .35 oz/in at 4.8v.
Wish me luck, if all goes well I'll have the training gear on and be out
burning some fuel tomorrow!!!

(being the eteranl optimist, I put a sticker on the nose that reads "EAT
DIRT!")
;-)

Was wondering if you used the collective setup that is posted on the
internet or devised a system of your own.???  Thanks for your time

You probably mean cyclic, as collective is not stock on the LMH. I would
lube the ball links and ground run it for a few tanks(2x4 thru skids).
Exercise the cyclic while it runs and see if the ball joints break-in.

If the servos are humming, it means they are using extra current, and the
current use skyrockets when micro-servos are bound. You risk losing the
battery if you fly with humming servos.

What you call collective is actually cyclic. The LMH has no collective, but
that's part of it's charm :)    The resistance is fairly normal in new ball
links, but please do yourself a favour and don't sand the balls, that will
make them like sandpaper to the inside surfaces of the links (you'll end up
with sloppy controls in no time flat).
You can relax the links by GENTLY squeezing them with a pair of pliars, and
then just enough to make them move easier on the ball. Your mileage may vary
of course, but be aware of what you're doing.

I learned with an LMH and once you're into comfortable and controlled flight
with it, you're ready for a bigger machine. The LMH is actually pretty hairy
in comparison, but I've crashed mine at least a dozen times and only had to
wipe the dirt off the blades and start it up again.

    Best of luck, and have fun.

Dan:

He  does mean  collective they have been modifing them to have it a
collective machine.

Hi All,
True...mis-term on my part (I knew what I ment!) Cyclic!
Thanks for all the input. I'll try "relaxing them a little with pliers
and break them in by use a couple times.
Hopefully if this rain holds off until this afternoon I can get a few
tanks in and see if the resistance is decreased. If it keeps up I
need to explore others, as I'm worried about the servos based on some
ofthe replies I've gotten.
Thanks Again
