With the new 21.5t motors(200000kv) hitting the market today, the 5.8fdr might be too fast to control without traction rolling everywhere....Hopefully the tracks will stay short, and give the diehard brushed guys a chance when club racing....lol..

The 4 pinion options listed are just thBeer Delivery Car Works On Land & Sea | Incredible Thingse 'new' ones. They already make a 20T so it doesn't need to be listed as one of the new options.

But...I don't think the gearing will just LEAP from 18T to 22T.
However, Tamiya every now and then do something REALLY stupid.
i.e. TA05 M-Four. LiFe battery and 380 motor. What were they thinking?

M07 is on the way!

58647 M-07 Concept Chassis Kit
– full model change !! new chassis [M-07 CONCEPT] appeared!
– to pursue a nimble driving performance of the front-wheel drive unique, high-performance electric RC car chassis assembly kit of which stuck to maintenance.
– mainframe a monocoque type of vertical split, better maintainability while ensuring the rigidity.
– in particular, the exchange of differential gear is reduced as much as possible the degradation point of the suspension, accessible from the bottom.
– suspension is double wishbone 4-wheel independent of CVA oil damper maintenance.
– arm and ringeji in the long of the specially designed products, setting wider to also feature.
– the drive system is configured without a loss, such as using a full ball bearings, oil-filled gear diff or universal shaft.
– monocoque type chassis with excellent maintainability by the vertical division.
– adoption of a broad long suspension arms of the setting width.
– full ball bearings, oil-filled type gear diff, universal shaft, standard equipment, such as high torque servo saver.
– M = 225mm, L = 239mm, 2 kinds of wheelbase can be selected.
– full length: approx 332mm.
– full width: approx 164mm.

Hey guys!! I wanted to ask if I could possibly get some M-chassis advice. I am a retired M racer and haven't owned or had my hands on one since about 2005-06 when our track and LHS closed down, so I am out of the loop when it comes to anything to do with them now. I really, really miss owning one so I would like to buy another. What I want to do is build something really fast for wide open fun running in parking lots, BL powered and of course lipo. Now when I raced them I had an M-02 and M-03, and my biggest gripe with them is that you could only run shotgun style packs in them. Have they come as far nowadays for you to be able to run lipo packs in them? Also, what is the maximum KV motor that the most recent chassis diff/trans can withstand? Sorry for coming off as a noob, but as I said I have been away from the M chassis for a loooooong time.

Racing is rarely defined by KV, but by turns. I ran my M05 with a 17.5 and it was spectacular. It's got a 21.5 in it now, and it's still mighty fast. The biggest gear that it's designed for is a 20 tooth pinion. Now, the car is FWD, so it's hard to load up the drivetrain. I don't think there's any limit I'd really put on the KV I'd put in there. It'll just spin tires.

Don't lock the diff though...

.... I have a M05 for sale. If you want it, PM me. It's brand new, and has never seen a set of electronics. Then you get your choice of body and wheels. Upgrading it to M05 v2 spec is $10 or something.

Yes, I know about the shotgun style packs, but they are difficult to find in the amount of MAH that I want. I want at least 5000 mah, which is what I have plenty of in rectangle style. What I want is a RWD M chassis

The Hobbywing 13T ezRun combo is a great powerplant for these cars, but if you're going insane you can go bigger. I've heard of people putting in hot modified motors for velodrome runs, but they went easy on launch and didn't use brakes otherwise the gears shredded.
The M05 v2 R spec is cheap right now from rcmart so use that as your starting point. It even accepts standard lipo packs.

Thanks for the motor recommendation!! I'm not looking to do insane top speed runs, but would like to put together something that can at least get close to 40-50mph or so LoL. I want to go RWD this time around so it's looking like it will be the M06 for me.
