Break in?

[tp311]

My gear mesh seemed extremely, extremely tight when I got it. I put a little oil on the main gear and it helped a bit but its still tight. I only got to fly two batteries though, does it break in more? Has anyone else even had this problem?

Thanks, Tyler

Mine the motor is real tight the gear mesh seems ok
I think the motor is the deal
I have not gotten to spin it up yet so I will see what happens
Hope it is ok

I thought I was the only one. There doesnt seem to be a way to loosen it either.

I was reading some posts that the aussies put up a few days ago, someone recommended taking a dremel wire wheel to the pinion to burnish it down some and relieve the tightness..Mine seems to be fine..5 min flight times doing mild acrobatics..

[tp311]

Yea mine was so Tight when I got it that as I landed and powered down the pinion and main gear would bind and the rotation of the blades would spin the heli 3-4 times on my hardwood floor. Its better now, only spins about once when I land, but still seems tight. Does the msr main gear fit? On HH the part listing says msr/mcpx main gear and I have a spare one of those, maybe I'll try swapping them out. Oh and I am 99% sure it can't be adjusted.

I've got about an hour of flight time on mine, and the blades spin for about a second or two after landing. The heli makes about a 1/4 to 1/2 turn on a tile foor.

Yea, so far I only have 2 batteries through mine. Anyone other than CA having this problem? Just wondering bc everyone that replied is in CA.

I'm a little worried. I have to throttle about 50% just to get my main blades to start spinning. Basically I get a lag from when my tail blade spins to when my main blades spin. I feel like the tight mesh is robbing me of power. On normal mode I have to throttle about 75% just to keep a hover and I'm using the dx7 settings from the manual.

[tp311]

Mine wasn't quite that bad, at first it was about 25% throttle now I think its down to maybe 15%. I think I'm going to email horizon. My servos also twitch extremely bad while waiting to spool up, anyone else have that happening?

And Vader, what charger are you using? Do you have and old msr multi battery adapter hooked up to a good charger with a bunch of the old to new adapters on it?

Thanks Tyler

Mine also has a tighter mesh. Some of yours sound tighter than mine, but mine is still tighter than I'd normally set it. I'm in WI, not CA.

My servos are also chirping away after the bird initialized. I too was wondering if this is normal.

Oh well good at least I know the servos are semi normal. But the gear mesh still seems weird.

[LiqrSicc]

My servos buzz too. I guess it's normal but I didn't realize it until you guys mentioned it.

After polishing my pinion with a dremel wire wheel my heli runs smoother and the blades turn a few more revs when I hit throttle hold (and the heli does not do a little stop-and-spin now). Worthwhile doing if your mesh feels a little too stiff imho.

Did you dremel it with the motor still installed or did you pull it out?

I pulled off the main gear, put a bit of sticky tape over the motor and dremeled it inplace, spinning the pinion around to get it all polished up nice and shiny.

Cool, I'll give that a try, thanks.

One of the issues that is causing the motor/ pinion to be tight is that the mCPX is using a brushed motor. The cordless motor in the MSR turns much freer. Nothing really wrong with the mesh just how hard a brushed motor turns. Just like the motor on the 120SR or the CX2. It will always be tighter than the MSR.

I've got the same two problems with mine.

The mess is SUPER tight and the servos sound like a bunch of angry bees.

I thought it was defective but I see I'm not alone.
