Transmission

[GorillaMaxx360]

what a decent trans for the maxx 3.3 or a E-Maxx. Well here is a list for everything you would need for a bullet proof Emaxx tranny.

1. E-Maxx Gear Box Stock $10 (stock will defiantly hold and will cut down on weight) Here
2. GorillaMaxx Single Speed Conversion Kit $75 (this will lock your trans in second gear, and you want this because the Brushless motors these days are so powerful it just blows right past first gear and it becomes useless) Here
3. OPTIONAL -if the G-Maxx single speed is more than you want to spend than you can use the stock trans case and just buy the coupler that they make that is only $12 Here
4. E-Maxx input shaft $7 Here
5. Modify Input shaft and replace roll pins $0 a half an hour working with your hands removing the pin and making minimal grinding to a hex wrench or drill bit and then pressing it into the hole where the roll pin is (this upgrade greatly helps because the roll pins usually snaps under high power Brushless systems.
6. RC monster Steel Idler $15 (not much to say here just put it in and go) Here
7. Second gear for Emaxx trans $3 (plastic holds pretty good so metal in not necessary) Here
8. E-Maxx Idler shafts $4 Here
9. Bearings = (4) 5x11 (3) 6x12 $9 at your local hobby shop to get these in sealed bearings
10. Motor Mount Stock $8 Here Hopup $17 Here
11. Misc screws for Assembly

That is pretty much everything to bullet proof and lock and emaxx tranny into second gear for brushless. I am not sure about the other trans but they would probably be much more expensive because there are whay more gears, shafts, bearings, ect... for example look here and thats just how much a stock 2.5 trans costs and the 3.3 is bigger.
Hope I helped
