Here's done pics of the plastic gears with about 3-4 3s packs through them in my super. Kinda hard to see but there's barely any sign of wear. I only took pics of the 2nd large gear.

Erik, You think the Large 2nd gear is gonna rub in the case? Is this the case mod you speak of?

I dont see any issues with the large 2nd except for clearance with the adapter on the small 3rd. That was taken into consideration with your new adapters so that should not be an issue.

Here are some pics of the case mod. I will also update the 5th post in this tread everytime there is a change so that way you can always count on going back to that post for the most up to date info.

You need to modify the motor side of the case. The large 3rd and large 2nd ended up getting pushed further towards the motor.

You will need to drill a hole in the small 2nd bearing pocket. Put the bearing in and then use the drill. This will ensure you drill accurately. If you have a 5mm drill bit, perfect. If not, a 3/16 or 13/64 will work just fine with some work. If you use a 13/64, you wont be able to use the bearing as a guide. Use the 3/16 as a pilot hole and then step up to the 13/64.

The large 3rd needs to have the case ground. You can do this a lot of different ways. When I try to do things the first time, I make sure I dont use fancy tools such as my mill so I can be sure you guys can do the same. I ended up using an exacto knife for the most part and then cleaned up with my dremel.

Thats it for the case mods.



The bearing/gear/adapter setup is different now. Here is the current configuration, motor side to non motor side:

2nd
5x10x3 bearing, gears, adapter for 2nd, 6x10x3 bearing, .5mm shim

3rd
.5mm shim, 5x10x4 bearing, gears, adapter for 3rd, 5x10x4 bearing, .5mm shim.

I sent out 5x10x4 bearings along with the corrected adapters for the 3rds yesterday. As soon as this gets set in stone, I will modify the adapters so that we can eliminate the .5mm shim on the non motor side bearings. No matter what, we will still need that shim on the motor side for the 3rd

Here is a picture of my gear contact. If this does not work, I think we are screwed LOL. I think it will be just fine.

Erik,
How close are your screws to the edges on those tubes? I haven't done mine yet and looked and it dosnt seem like there is much that will hold them on.

They will be somewhat close to the edge but you should be able to work it out. My holes on the Berg tube have .060 between the edge of the hole and edge of the tube. The MT is .030 (radius) wider so you should still have .030 to work with and maybe more if you feel like cheating it a bit when you drill your hole.

This brings up another point about mounting the tubes. After looking at it some more, I wouldnt use one of the standard Berg holes to mount on the MT case. I would notch the bearing pocket on the tube a touch and then do 4 brand new holes.

Got my replacement adapters.Thanks Erik! I have a comp Saturday, so I wont be trying these until after. My plan it to run plastic cases front and rear with drilled berg gears in front and plastic out back. That should get me into the 3lb range. With a delrin T1e ss.

I should be putting together a front axle this weekend, it's just going to be the cases and tubes though, no axle shafts or gears yet. I'll post up a pic though

Just started on my rear axle today. I used the dlux adaptors with all the berg gears for now.

That looks great! Have a weight on it as pictured? What type of motor is that...a standard 540 or some lightened version?

Nice axle, I'm waiting for the MT gears to come back in stock. Gotta try them before doing berg gears

I will get some weights tonight, didn't remember to get before and after shots of the rear, but I will with the front. Standard motors too, I'll get a weight without motor too for comparison

Nice 13.122oz with berg gears. I can't wait to see this case and tubes with MT plastic gears. What axle shafts are you running?

Did you have to modify that dlux upper link mount so that it is centered on the axle?
