Default To show clearance between metal gear and servo using paper (pics)

Just want to show clearance between the metal using a piece of paper to show the clearance. There is clearance . You should give this a try with your plastic gear or metal gear. Just something you can try.

Did the paper slide freely through or did you have to turn the gear to feed it in? just got mine and i have to feed it in... think that means i may need to get the sandpaper out..

Got the metal gear installed a few days ago and it's a fraction smaller the plastic one and doesn't touch the servo

When I called HH last week this was the method he taught me and it does work really good in achieving good gear mesh. I remember the old RC days this how I set gear mesh on my buggies. Thanks TNT

It doesn't have anything to do with gear mesh. It's for checking to see if you have clearance between gear and elevator servo..

I tired the paper pass this mornig and it came out with little holes in it. After looking at it thought a magnifying glass, I can see the gear rubbing the servo. Is there any other way to fix other than sanding the gear down? I fear if I do that, I will have to do that every time I need new gears. The other option is to send it back to HH, which I may do if it eats the servo.

I don't think so.

I had mine wipe out the servo in one flight and can say I even was able to get a piece of paper between where it looked like it had enough room.

Personally while it would great if this could be relied on, I think there is some flexing here that would allow a piece of paper to go in there, but that doesn't mean its not going to hit.

For me I took mine and found the ID of the gear section was 14.40. Then I took it and shaved it down to 14.25mm and I can also tell you, if it's the metal one, it's going to take way more then just sand paper to get it down as that metal is hard.

Also I had to replace the servo so I don't know if that had anything to do with it, but since then I haven't had any issues and have took the helo apart several times since the three weeks its been this way and I see nothing happening to the servo.

But all in all, you could also try another plastic gear if that is what you are using, and or even the same if its the metal one as it been getting found that they are not all the same.

Either that, if you are using the plastic, just get the metal one and shave it down as just saying with that, you probably will never replace the gear again so it should be a one time job.

It's easy to sand. I just fed a piece of rough (maybe 200-300grit?) through and once it was between the gear and the servo I just turne the blades by hand both ways for a minute or so. Allowed just enough clearance (Any clearance is enough clearance really). Easy peasy.

I will probably do just that, once I can find a metal one. Until then I'll try the sandpaper trick.

There is clearance for sure, I've had the chance to check mine, and another 2 of my friends, and never seem to have the rubbing described here in other threads, not denying anything but 0 out of 3 so far in my case.

Yeah at least for me, I don't think I have ever seen a helo with so much variances of the problems it has had.

For sure seems to be a crap shoot on how it will be so I think it definitely is one of those helos that will be hard to say when you read from 3 or 4 people, oh mine never did that, and think, that means it won't on yours.

Would probably be a really good idea to check over all the stuff in that before you fly it sticky and verify everyone of them is OK.

As per someone suggestion on this forum, mine had a high spot on the A gear that was rubbing on the FET. I managed to get some wet & dry 320 sandpaper (used dry) into the low spot and kept turning the rotor head by hand until it freed up the high spot. Then I double the sandpaper (not exposing the rough side to the FET) and repeated the process until I could see some daylight between my A gear and the FET. Before I ever flew my bird, I read all the suggestions on this forum and I can tell you it really paid off for me.

I just run over the heli three or four times with my SUV and then it drops easily into an envelope. Costs over a dollar in stamps, but it sends the message that HH needs to hear.

I am just checking my new 130 per some of the posts here, and right away I noticed the gear is mighty close to that servo. I can get the paper through by turning the main gear. Is the consensus to go ahead and try the sandpaper fix first ? Thanks
