Why wouldn't the T5M just roll out with the 3 gear transmission?

Joe, it is still unclear if it will be any good. It has been tried before by xfactory and durango with poor results. Maybe AE got it right, but time will tell. The word on the street is that the 3 gear will loosen up the rear of the car. How much? We will see...if/when it actually comes out. I suspect that AE designed the 3 gear for European style track....like the up and coming worlds. It would not be the first time AE has designed parts for the worlds. Plus it would be good maybe on carpet and astro track. Maybe even SRS. Cav has given no clear indication that it is good yet. I am not sure if Rivkin has been running it or not at SRS

My B5m kit from almost a year ago came with those improved gears.
I bought a mid motor conversion kit for my B5 mid-summer and it has the grey idler gears. I just broke open my B5M kit over the weekend, bought it in October (I think - maybe September) and it has the grey idler gears as well.

Because it is a tuning aid for a specific type of traction. In MM, the 4 gear will work best the vast majority of the time.

Was this a result from a different chassis, or have you tested the 3 gear already in the b5m to draw this conclusion?

What's interesting, is I still haven't heard if it's badass or not. Just that a MIP guy has won with it.

The stuff on facebook that Cav posted, didnt seems to make a glaring upgrade. All he really said is that he was still working on setups wit hit. Most people are going off the past results of the MM 3 gear. Maybe AE got it right. Time will tell. IMO, this is a high bite option part created for the worlds.

The three gear top shaft just came in to stock.

It changes the direction the motor rotates/torques against the chassis. In a RM car, you want the motor's rotation direction to put pressure on the front tires, so the dang thing can turn, because there is so much weight out back. It gives the car a balanced feeling. RM car's accomplish this with a 3 gear trans.

In a MM car, because all of the weight of the car is inside the rear axle, the balance sits the other way. On-throttle, they CAN lack REAR bite, instead of front bite. So you run a 4gear trans, so that the rotation of the motor torques the chassis to put pressure on the rear tires instead. If you run a 3 gear trans in a MM car, you have the potential to really limit weight shift to the rear of the car.

This is stuff I learned 20 years ago, and still have modern day experience with when I was running the DEX and Cougar (which only had 4gear option). It's published info you can go look-up yourself. As a matter of fact, Durango has a GREAT little graphical diagram that teaches the whole thing.

I will venture to say that MOST tracks, the 4gear will be better. On SOME tracks that have high enough traction... the 3 gear will be better. Either way, releasing the truck stock with a 3 gear would be a mistake, as it certainly won't be the way to go for most tracks. So in conclusion, it is my opinion that it will be a tuning option for those that want the most amount of on-throttle steering as possible, which will usually only be tracks with the highest levels of traction.

I will certainly be buying to try out.

Just ordered a B5M, can't wait until it gets here, this will be my first venture into the kit world (all RTRs in the past).

Thinking of going with the Turnigy TrackStar combo, the 120A 'turbo' ESC and a TrackStar red-can motor. Any recommendations on size? I was thinking 17.5T until I start racing on a regular basis. How about gearing?

How bout we ditch both the idler gears?
Less rotating mass, stiction, weight, etc. I know it's easier said than done, but why isn't it being done?

Direct drive offroad? I'm not sure if the spur gear could handle it...but hey, it's worth a shot

You propose replacing them with a belt?
Think it has been done before.

I've been using the track star ESC and 7.5 motor for several weeks and both have been great.unless your going to run stock class I would get a lower turn motor maybe a 9.5 or 10.5.in the manual is a gearing chart thats generally close.
