Traileater, the worm drive dosn't free wheel like a ring and pinion.

So no freewheel front dig. But if the dig works smooth with power on and off it may not be an issue. Driver preference I guess.

Worm gears are ineffeciant by design. Lots of sliding friction going on which can get real high with a lack of lube.

Smaller pumkin for better under axle clearance.

Also it makes it easier to get more gear reduction in the axles which help to get rid of tourqe twist.

the gear jelly works great on this rig, I know Jake loves it and plans on getting more (and I plan on stealing some once he does ).

Gearjelly has worked wonders in my other rigs, and sounds like I was making the right move putting some in this one!

Don't know what all is in there, but it just flat out works great!

May be worth opening up your axles and checking the worm gears for lube. Rich had mentioned they use the "smart diff" grease. He also said a good marine grease would work as well. I guess the main point is make sure they are lubed well.....very well.

Hope that helps.

Just did a tear down of the axles and trans on my rig.
Axles are lubed, but its like a silicone grease.
Trans was near dry, some type of liquid type lube in there.

Rebuilt with gearjelly in both axles.

Trans lubed with gearjelly on the gears only, black grease used on the shift forks and engagement dogs lubed with a very small amount of black grease. Do not use gearjelly on the dogs as it doesnt allow it to fully engage as gearjelly is to thick.

After looking in this rigs internals, I am freakin highly impressed with the design!
Major Kudos to the people who designed this rig!

Pics and how to' to be posted later today

Thanks all for the comments. It should be noted that you do not need grease on the internal transmission gears. You can run it if you want, but it is not necessary. As for the gears, we did find that our smart grease worked well, but we have tried marine type grease as well.

As for the body sides, you can literally bend the side with your fingers along the body line.

I'll try to answer and view posts as often as possible over the weekend.

It should be cranked down and only slip under a severe tranny shock. I have read a few saying they are slipping, they really should not.

I just tightend up my slipper, waiting on the batts to recharge. I'll let you all know how mine holds up.

Well, after adjusting the shocks, goin thru the axle and trans, this thing is freakin phenominal. I dont even have tires weighted yet and this thing performs better than the old rig.

Installed a 17t pinion with the 45t brushed motor and she does pretty good now.

Heat?

Im awaiting mine and gonna do a complete teardown to rebuild just to get myself familiar with everything about the truck.



@ Rich - when you say the tranny internals dont need grease is that because of the material used? I cant recall what it was technically labeled as but I slightly remember something back in the XX days about the trannies on them. The gears were made with some type of self lubricating material. I cant recall exactly but if its something like that I remember running them dry and flawless.

one last question that the directions probably answer but could you tell us what weight oil the shocks are from the factory?


thanks for everything you and the Losi have done on this.

The Sidewinder will run brushed with a 3S.

Can't wait to get mine and check it out.

I have to say at this point there is no way in hell I would trust this thing to comp with. Mine may be for sale soon! Got mine and haven't taken it out of the box...what a colossal disappointment. Long live the BERG!
