2 speed

I've seen this asked a couple of times so I thought I'd share how I put a 2 speed in my Traxxas Rustler. Some background: This was my first nitro RC. I've been working on cars all my life but my background is IT and Engineering. I got the stadium truck from my dad. He bought it probably close...

So I’ve already converted a few 2.5 tmaxxes and they all have been pretty good but I’ve been wanting to do one with one of my 3.3 chassis and have really wanted to keep the two speed gearing, since in all the 2.5s I’ve single speed converted them. Other than having to still use the servo brake...

Hey community, I was gifted this amazing car, I know it is very old/vintage RC car, but it's practically new since was only ran a couple of times, not even a quart of Nitro has ran through the engine, and I would like to use it to intro myself to the hobby. I see there were a couple of...

Hi, i'm using my mp9e Evo to build a speed runner. Currently i'm only getting to 120km/h(mamba monster on 6s), because I can't put bigger gears as the motor mount can't be moved further from the center diff. What are the options to solve this? A smaller gear on the diff is also not possible...

I am looking for someone who can help me out with a little issue I’m having. I have the tmaxx 2.5 w/ a TRX 3.3 engine swap. But here’s where my problem is. It was running fine with the 3.3 through break in and for a few tanks of running and now it will not shift into second gear if there’s any...

In the past week I've put a new clutch and two speed tranny on my acme cyclone and it doesn't seem to shift in to second, so I was looking at the tranny to try and adjust it, but I can find the screw in the clutch anywhere and it came with no instructions, so if anyone has any ideas, some help...

Hey guys going to be replacing the crap plastic gears in my jato tranny. I've found two sets one is all hardend steel and one is Aluminum. Both by hot racing weight really isn't a concern considering my jato is 100% aluminum. I'm just wondering if there is any advantage to either. I'm assume the...

Hey guys, I have managed to smoke my 2 speed again. The first time, it blew the wide ratio gear set. I replaced it along with the primary clutch. Second tank in and it blows again. This time the wide ratio gear set stripped, the pins flew out of the primary clutch and the bearings on the...
