Intresting info about the counterbearing

[Flybar-less]

I saw this on RR. So it sounds like it is a must on the Orbit.


Hi smartguy,

you don´t need the counterbearing for your LOGO 600 with Tango motor. The counterbearing is only for outrunner motors

Definitely interesting. Anyone tried this with a Neu 1912/1Y/H?

[Flybar-less]

I use it with the Neu 1910 and 1912, thought being, it's got to help the motors bearing life, or a least is some insurance if one of the 3 goes.

I'm running one on my 1915-1Y and havent stripped a gear since installing it, before that i managed to chew up a few!

[Mercuriell]

Can vouch for the outrunner - my Z80 chewed up one pinion and 2 main gears before fitting - none since

All I can tell you is why not use it regardless of which motor? Personally I find it a nice peice of mind as it keeps everything in line perfectly. Do note that I found on the Orbit motors and the NEU that the shaft went all the way through which was nice to have to cut and fiddle with. I know Ralph says not needed and well,,, maybe it is not for some but I like the idea myself. Each to their own, :wink:

Sorry for being such a thread spammer, no chance of flying where I live for awhile, -48 degrees celcius outside right now, pretty dam chilly!:bawl:Chair

iiiiihhhhhh... Your forgiven!

It seems strange that he would state that his Tango motor shaft is too short to use the counter bearing. Normally you would have to cut it down so you could use the counter bearing. Maybe that is what he meant?

[Ticidytoc]

Actro/19T .7, still have not taken the counter-bearing out of the package. I guess if your not running 1.21 jiggawatts or a 690/710's on it it works fine without it using the big boy pinions :wink:. Of course I only do some mild aerobatics with mine, none of that hard-core stick banging stuff for me.

[fogger]

from what I have understand from chatting with "Mr. Aeromodel", it is not whether the motor is an outrunner or not, it's whether it has a nice strong hardened shaft and good bearing support to prevent shaft flexing. The tangos are high quality, so are the neu's. Apparently even Actro's have (or had up until now) non-hardened shafts (or not hardened enough) as they never were faced with this issue before. That and some of the "cheaper" alternative motors out there are why this whole bearing block came about.

[OICU812]

Exactly true fogger, it is about the quality of the motor shaft more so than anything.

Hey guys,

We never had the counterbearing on our 600s with Orbit 30-12 Heli Expert.
Works out perfect without the counterbearing. Still have the same Maingear in it since IRCHA. :)

Take care

My heli was making a clicking noise when I rotated the main gear backwards. Fearing that the pinion might have been coming apart I took the counterbearing and motor off to find that the counterbearing shaft was getting galled in both the pinion and the bearing that it rides in. I felt the bearing and it was not terrible but not great either so I just left the whole mess off and remounted the motor. The motor has very little play and I am hoping that my style of flying will be ok without the counterbearing. The motor is a Z50A-800 on 10s-3700. The pinion appeared to be in fine shape.

[Mercuriell]

The Z50-800 has a lot of axial play in the shaft - I had two pinions separate and one gear strip before I fitted the counter bearing - no probs since - let us know how you get on !!

Is that like the shaft being scored? After about 12 flights I found mine to have a ring where the counterbearing slipped on the shaft! Is more of a discolouring/polishing than actual wear. Strange.

Yes, you are correct. It is discolored to a rusty brown where the little 5mm shaft rides in the counterbearing. It is also discolored about the same at the upper 5mm or so even though approx 8 or 9mm rides in the pinion. I don't think that it has worn very much but I did try wiggling the shaft after inserting the long end in the pinion where it normally rides and it is sloppy.

I was worried about that so I checked the axial play on this motor and fortunately for me it has very little. I have seen other Zpower motors that have at least 3 or 4 times as much brand new.

Hey guys, sorry to sound like an ignoranus here, but what is a counterbearing and what's it for. Any pics of it? I'm planning on getting a Logo5003D soon and i've never ran across anything like this on my previous helis.

Thanks

[3secondsToImpact]

Well i just happen to have those pics for you.

As the pics show it's a small housing with a stub shaft and a bearing - the idea is the stub shaft goes in the end of the pinion and stops it from floating sideways so much - not necessary on the 500 but good for some motors on the 600 like the Z Powers

[3secondsToImpact]

Some motor shafts are long enough to have it work without the included stub.
In my case that was not an option, had to cut motor shaft to a length of 14mm which allows the shaft stub to go up inside pinion to capture.Another positive is battery protection( fast spinning pinion + Lipo, not good)
