I have a HLTiger S & S with the plastic gears/track and whenever I put too much stress on the gearbox (turning on a "grippy" surface, steep inclines) the gears slip. I've opened it up & can see the sprocket gear & the one that drives it are the culprits. I've tried shimming the gears a bit between the sprocket driver & the edge of the tank so that they mesh tighter but it still slips under pressure.

Will a Matos metal gearbox solve this once & for all?

I might be off track on this one, but I'm pretty sure that someone has previously mentioned that the Heng Long gear boxes have a clutch mechanism concealed in one of the gears so as not to overload the motor if binding occurs. This could bne it.

Cheers Mario

hi downtown most people opt for the metal gearboxes as well as the tracks as IMHO it helps a lot the clutch is in the first large gear after the motor some people have C.A.d the clutch with mixed reports works for a while hope this helps

Thanks, yes, I tried using super glue on the clutch first and when I continued to have the problem I opened up again & could see the gears slipping. I guess I'm not clear on this one. Will the metal gears set from Matos end this once & for all? Cheers.

yep as theres no clutch in the metal gears just make sure you loosen them up following richards faq at the top of the page and all should be well

You have spare boards right? The reason for the clutches is to save the electronics. That being said, I run all metal gears. The boards are cheap enough to keep changing them.

So those are my choices? To hear the gears slipping or to burn out boards? Seriously, I don't run the thing that hard. Mainly futzing around the house for 10 or 15 minutes at a time. Am I still going to be burning out the boards? Thanks.

No those are not your only choices..
If your clutches are locked with cyanoacrilate and the gears continue slipping, it is likely your last gear slipping over the final driveshaft.
First ensure all your gears are aligned, if not, align them putting washers in their axles. Sorry no pics. Then you should drill a small hole (1-1.5 mm) through both the plastic sleeve and final driveshaft (the big one, where the sprockets are inserted), and insert and glue a piece of wire, steel wire, paperclip wire, anything relatively hard with an adequate diameter. No more slips and, of course, not necessarily burned boards at all...
In my first HL Tiger I've encountered this sort of problem and once corrected it never slipped again.
I'm going to look for some old pic of my "corrected" old HL gearboxes.
Hope it helps

Jose,

Thank you thank you thank you! That's the info I needed. Yes, it is definitely the last gear slipping. Cheers.
