Emaxx Tranny Keep It Two Speed or Go Single
 

Im going to biuld my self a crawler useing a Emaxx tranny I have and was wondering what you guys do with them.
The land that I will probably be using it on isnt all rocks so I though of keeping the two speed for a bit more wheel speed between rocks. But first I thought I would ask what you guys do about the two speed.

Thanks Tupers

I think that you should go with a single speed. You can gear it to have enough wheel speed and also to keep it slow in the rocks. The change in the 2 speeds isn't very much anyway. So I say go single speed.

It would be cool to be able to shift to 2nd and nail it when you wanted some more speed.

but...

the problem with keeping the 2 speeds is there is a TON of slop.
Way to much slop for a crawler in my opinion.
If you let off the throttle on an uphill climb, it will roll back about a foot before all the gears get lined up and engaged again.

Id keep it locked into one gear or another.
Its a stout tranny.
I run one, but mines locked into gear.

Single speed is all you need. Check out GorrillaMaxx for a clean single speed conversion and a single motor mount...

Funny I have three rigs with e-maxx trannies in them and once you stop on a uphill they dont roll back. They do however have about 2-4 inches of roll on a level surface, and that's depending on your tire size.

The gears are already engaged when climbing uphill. If the amount of slop you say is true then it could roll forward (uphill) for about a foot untill the gears engage. Gravity wont let it do that.

roll down
 

i still have the two speed tranny i like the idea or a little burst of speed . I to have the freewheelen under no power i just set the trim up or down bepending on going up or down hill ,

Thanks for all the help guys.
I've decided that Im going to keep it two speed for the moment,but lock it in one gear useing a colet on the gear change shaft. That way I can test it in both gears to see wich one is better for my kind of terrain.
Thanks again for all the help. Hopfully I will be able to do a biuld thread once I have a few other things done and out the way.
