I cannot send it back anymore- too late now. I do not now what a 'çan' is. But a gearbox with lower turns was not advised since it makes this big and heavy Leo too slow.General Jumbo01 wrote:Personally, l wouldn't use the HengLong metal gearboxes as they are rather low on material quality. The Taigen boxes use better metals, reflected in their prices, but l guess you can always be unlucky and get a defective one. Why not send it back?
The HengLong nylon geared boxes run quite well and, unless you can't live with their gear ratios, I'd suggest you use them until they break. The Taigen model names, although they sound like gear ratios, are not (yes, l was fooled too).
Generally, all of the HL/Taigen/Torro motor and gearbox units are of basic quality. It may be possible to simply replace the motors with a quality 'can' with lower turns that would provide lower speeds and more torque but l'm not yet familiar with smaller sized units yet.
Always add a tiny spot of oil on both ends of the armature shaft bearings and then feel free to grease liberally the gearbox gears. Try to use a light weight grease that doesn't attack plastics - if you can find a Teflon grease this will be perfect but otherwise some model train greased do a good job.
Unfortunately, cheap brushed motors without ball races will always be noisey but l don't know the smaller brushless cans yet so cant recommend one, but with two brushless escs you'd have to get an 'open' spec MFU. Hope this helps.

My Taigen gearbox comes with ball bearings: https://www.rctank.de/Leopard-2A6-31-PR ... -axles-low
I have put a liberal amount of Teflon grease on the gears. I will also do that to the armature shaft bearings. Thanks for your advice.
I agree the nylon geared boxes that came with the tank did a better job- no wobbling at all. And that for a much cheaper price. So I will swap later the Taigen 380 motors to my plastic Heng Long gearbox and see if that goes well. The problem with that gearbox is that one of the electricity cables is loose and has to be soldered - I am not handy in soldering but a nephew of me probably can do it.
For the moment I will continue to use this Taigen box until it breaks. It is too expensive to to throw it away after one month of use
Probably after all, it is this what caused the excessive wear and later the track breaking: viewtopic.php?f=33&t=26504
And it was probably augmented by the fact that this Taigen box had already defects when it arrived to my home brand new.
I am fairly new into RC tanks and this adventure into the swamp was not my best move. But then again the plastic gearbox was abused too and hold its own. So I have become weary to buy expensive gearboxes which have loose drive shafts even before they are used. And I will never ride again in this abysmal sort of clay
To be honest I have learnt the hard way that this wet swamp clay is just not suited for my tank.
All of you , thank you very much for the time and effort you made to help me!
