A G1 Single Speed kit and a RC-Monster idler gear should do...

Even with a two speed the steel idlers really beef the trans up.

I'm running a G2R with a 9XL mamba max combo, with a single speed and stock plastic idler, and i tore up the rear diff and the tranny is still runnung smooth

What battery packs are you using?

How well is the MM/9XL doing?

I went trough all the stock idlers on 3 runs or so. But I was bashin pretty hard. Even stripped a second gear clean smooth. went to the single speed and same thing, plus broke the wimpy pin that holds the gear on the top shaft several times.

Larry is running 2 x 2s2p 8000mah lipos.

Hows that 1950/7 & 9920 combo working out? I was considering that combo for my Supermaxx Emaxx.

Actually, i havent ran my truggy yet, waiting on a servo/receiver and have to make 1 last bracket.

Just at looking at the new 9920, compared to the older one (with smaller black heatsink) i doubt and have a very good feeling about it, since when i ran a revo on 14 cells, 1950/7 9920 and they both ran cool, the 9920 did get to average temps of 140F but it wasnt bad, the lehner made it run ALOT cooler than the old 10L i was using...

The new heatsink is alot bigger, so i wont be using a fan.

Cut a hex wrench as a pin they are strong. or pic up a stronger slightly bigger pin and freeze the pin and put the top shaft in the overn the pin will shrink(or it is the other way around) and the shaft hole will get biger slide the pin and when they cool back down the pin will expand and the gear hole will shrink assuring that the pin will never come out. Of course i am not familiar with the top shaft so this may not be necessary or they might sell and aftermarket pin.

You are part right.

Don't use a hex wrench, use a piece of drill rod or a shank of a drill bit.

Freeze the pin and heat the shaft & gear (minimally the gear).

I can provide the right size pins for a minimal fee. I'm installing them in my HSR Slipper Kits. (To be released in the near future)

you're right for now Sylvester, got a couple 3s 8k packs coming to try 5s setups

Procharged5.0, I have not had a lick of trouble out of it. I'm going to 5s and hope it will be ok, according to BrianG's calculator I'll be close to 40 then

I did that, it's an old trick, it's the easiest to do when the stock one breaks though. I don't run the tranny anymore. When I did, I had the single speed Ultramaxx gears.

Are you going to supply Mike with these slippers to sell for you?

Still waiting on pics Pro!!! LOL

been waiting on the pics for several months now....hmm...
