Is the Main/Idler Gear Really THAT Weak?

I have an Overland on the way with a PN Racing SO2 motor and GPM V2 Turbo and was wanting to know if the idler can hold up to the power for at least a while, til an alloy idler becomes more widely available.

I just drive around the house and nail jumps, I rarely get on the breaks hard and never do reverse to forward wheelies. I also drive outside sometimes on a dirt track or concrete. I want to know if it can hold up for a while in these conditions. Thanks, i just don't want to screw up my idler after a few days, that really is disappointing.

i had your exact same idea, to wait for it to become more available. I only ran indoors only, hit small jumps but used the overland alot. I never did any reverse to foward wheelies and rarely use reverse or braking in general. I thought i would be the last one in the world to break it b/c i kept it so clean and i was so careful b/c i know how easy it is to strip. Well one day i take , maybe a 3 inch up jump on to carpet and believe it or not, the thing wouldnt move as soon as it landed. i checked everything and it was that 1 tooth on the idler gear stripped. honestly , its really not worth it to save a few bux for shipping on e.b.a.y from japan then to be out of commision for over a week b/c you wanted to wait. so do yourself a favor and order it. Im sure you will be more at risk with a upgrade motor, i was only using a stock OL. this is one of the easiest things to break especially if you keep your diff locked and it hurts the most b/c w/o it you cant run your OL.

just my .02

I've had my stock idler in my overland and have been running it since new years day, it runs fine...no wear on it at all.

yes I pop wheelies a lot, yes it has a ton of runtime on it (just look at any of the pictures I've posted) and I run on dirt, short spotty grass, cement, hardwood, and carpet.

I also jump mine a lot, but I didn't learn to jump with the overland, I raced 1/10th scale stadium trucks for several years so I know not to land on power, that's how gears are stripped.

My hunch is mines lasted because I've never run my overland without the bearings on the idler gear

oh yea, I also have monster size tires on it, and I still pop wheelies with the truck setup like that, and no wear. I do have a GPM delrin/alloy idler gear in my toolbox in case it ever chips a tooth, but I see no need until it actually happens!

I guess I'll be getting some bearings and order that idler off ebay sometime, i just don't like ebay as much as something like d****** or tower or MZR.

I have been watching the bearing battle go on for a while but don't know which to get, i would like to have all 9 bearings in one thing but i heard the only ones like that weren't very good.

I have raced 2WD nitro trucks for 2 years and bashed an electric for 1 year. After blowing out i couple diffs you learn not to land full throttle.

By the way, what is the deal with the alloy/delrin on the gear? Is it half and half?

yep, the larger portion of the idler gear (part that contacts pinion) is delrin.

the smaller gear, that goes to the *spur* gear on the differential, is alloy.

Do youself a favor and get the Delrin Ilder Gear. i'm scared as sh*t to strip it but my Overland is out of commision anyways. I fried the whole controller because i put the batterys in wrong ONCE. OL's are good and all, but its too much of a pain to get reaplcement parts or anything. I have to now go on ebay and pay 36 for a TX. Its not fun. Make sure you get every part you can this way your not out of commish like me and OverlandPajero.

PS - Get knuckles too...those go fast. One of mine is already clearly bent but my OL also went down a few flights of steps .

you dont have to buy a perfex transmitter to replace it!

get a futaba 2pcka transmitter on ebay (AKA magnum junior). Should be about 20 bucks, MUCH better unit than the kyosho one if you have to replace it!

just look for 27mhz AM and get one with dual rate.


the easiest way to tell it has dual rate, is the steering wheel itself is chrome on that model, the cheap model without dual rate has a black wheel on it.

just make sure to get 27mhz AM and not anything else!

yea there's more brands, but the quality of those 4 is the best you can get.

heck, if you can find the JR XR2 in 27mhz AM, it comes with a computer screen and has tons of do-dads to play with

any would work just the same, get one that you like the looks of mainly, and next time you race some mini-z's with newbies you'll get a lot of confused looks
