Ive filmed a vid myself just haven't had time to edit/post yet... three things ive noticed in yours...
1.the CF ring is a bearing spacer, the flange on the front 10mm bearing goes outside the tranny and the spacer sits behind to keep the bearing from going into the gears (it give good clearance for the gears)
2.your right the extra standoff is there incase guys strip a thread or drill the hole in the wrong spot.
3.the standoff at the top that has the motor screw is best drilled out to 3mm so you can screw down tight on the motor.

Thanks for taking the time man Im sure there are guys keen to hear how you go with it in the MRC too.

yeah in the end i did drill that standoff out i may end up removing it entirely and just running a long screw with a couple nuts.

Ok guys ive hit my limit again, can't believe how quick these are going!

Good news is bearings and screws are what I'm waiting on and they are already on order... 1-2weeks and we'll be in business again.

I'll honor the $55 pricing until the end of January also

Ive had people ask about ordering just the CF plates so they can swap to another style.. answer is yes $30 posted in a STD envelope..

Cheers
Dan

What's the benefits of using right or left versions?

Its really just for setup allowing the builder to have the setup he is looking for...

For eg if the builder wants the motor on the right and reverse the GB having it at the back bring the motor forward then he would need a left side tranny... And the great thing about the way I designed the long output shaft is you can have a reversed tranny and not need a long tailshaft up front

With the flange on the outside is there concern of the bearing walking out?

If the flange is on the inside the gear can stop it from walking.

Its a snug fit and the outside bearing is on the short side and the drive shaft would keep it in.. atleast on mine and how its set up.

yeah what winner123 sai, once you put on the driveshaft if it does try to walk, the driveshaft will hold it in... also the bearings are such a tight fit on the shaft i had to use a vise to get them on, i don't see it walking.

Yup. Didn't think about the front drive shaft.

Yep there is close tolerances in it all, I have a pet hate for sloppy parts, how ever I cant be 100% sure what driveshaft people will use and if ALL of them will work, I did design it and used 3 makes of tailshaft for testing.. Junfuc, MIP & Axial WB8.. I got it as close as I could to work with these (even test fitted a losi LCC one which was good too)..... OK so the point im getting to is with the front bearing (flange out) it is sandwiched nicely between the pinned gear and the d/shaft BUT with different d/shafts it MAY require a little tweek which i'll detail now for those that might be new to building rc's.

If the front driveshaft is too snug on the bearing pull off the CF bearing spacer and sand it down to fit the d/shaft on, little bit at a time, don't get too carried away (this was the reason behind the CF bearing spacer, so the builder with a bit on sandpaper can build with no issues)
Now if you find after you fit the driveshaft that there is a little slop between the d/shaft & bearing then use some wheel bearing shims (5mm ID) to shim it to a nice fit.


There was a lot of work gone into thinking the GB design out, it looks basic at first but once you start to see the detail you can start to see how much time it took me to get it working right to make it suitable for a beginner (with a bit of know how) to a pro builder

here's my two pennies right side torque steer or blipping throttle lifts truck up and gives more steering but can destabilize the rig if not careful of camber or climbing.

left side torque sends rig downward creating more grip or traction on throttle no gain in steering at all. down fall if stuck it will bury it self into the rocks

I like both ways 6 of one 1/2 of another

Thanks for the tips Hulksta, got my tranny all assembled properly now, just have to figure out driveshaft for the fornt of the mini though, not easy sourcing (or making) a durable driveshaft that's like 45-60mm... i just wish MIP would quit being stupid and just spline their stuff all the way through so i can cut it to whatever length i want.

this is pretty awesome. i think this would be pretty killer in a scaler too. i could do lots better on the scale interior with something like this.

I have a scaler GB ready for testing... it very outside the box, was designed months ago and shared with my team but time restraints has held it back from production... hopefully not much longer till I can share the killer scale setup

cool dude. my main concern is how to box it all in to keep the grit out of the gears.

us scalers really like to get things dirty.

i was thinking you could just put a screen material around it, should be easy to wrap around and secure it between the standoffs and the CF plate, that would keep out the junk, while letting through air and water, no biggy as long as you wash with clean water and let it dry well after... i dont think there would be any good way to seal it up completely.

This is what mine will be going in once it shows. I have had a few scalers with trans wedged up front and they seemed to stay cleaner than when in the stock location.
