Default MCD plastic gears

Hello,

After yesterdays race where we ( we was two MCD) was several times changing two melted plastic gears( from 4) we are thinkink of changing to metal ones, but we are suspicioos that maybe it not a good idea

Please help with some ideas....

Thanks

P.S. Also track "helped" a lot it was sooo sandy with many small rocks and dry, and some Baja was faster due that in finals we needed to change gears ..[:@]

just as long as you leave a week point ....like the palstic spur gear with a alloy carrier.


one of the first upgrades for any 1/5 vehicle... a steel pinion


I dont know if MCD has steel gears yet

I'd second this, I also am on the original gears.

It sounds like there's drag somwhere, that's causing a build up of heat, do as Whizzy said, check over the transmission.

With the car off the ground, and the brake off, rotate the 2 front wheels together (clockwise) and you should hear some gear noise, and both rear wheels should spin at the same rate. If not something is binding.

yeah but it is known that gears melt when covered bearings get too hot etc causing stress on all moving parts best thing we found was velcro tound the side guards and round the bottom of shell keeps all the crap out

I'm running steel together with the original plastic gears and it works fine. In the matter of stones come in between, only the plastic one ist hurt.
I once tried comletly steel on all four gears and it cost me one of the pinions (missing teeth) and the clutch bell (bent), when i got a stone or whatsoever in between
I got them from the german site truckmonster.de , but I am not sure if he speaks english.
