Every brand of car should have its own class also.

In the future there shouldn't be any scoring, just driving.

Maybe for trophy races everyone can get the same trophy the just says "Participant" instead of the place that you finished...lol

Sometimes I think that is the direction the world is heading.

yep, I looked at the xx4 manual and they were keyed. My guess... tlr was lazy and just left it that way with no real reason, other than to save time and money.

the Picture of the new B5 gearbox tells that the top slipper axle/gear is 20. (same as B4 ?)

The idler gear is 31 on B5 (was 28 on B4?)

the Diffgear is 52 (same as B4?)

Why on earth did they use 4 gears in the transmission? Considering they needed a new case anyhow, it would have been easier to keep the motor orientation and use a single idler just like older designs. You could use the same motor plate on both the mid and rear motor configurations if they did that.

The only reason I could see for this is to make slipper adjustment easier with tires on, but it puts weight higher and adds unnecessary parts.


As for me, I'll wait until an FT or .1 kit comes out... So much has changed that there will definitely be bugs to work out. Don't want to go back to plastic rear hubs, either. Aluminum and CF for me back there.

I would imagine that plenty of companies tried out a motor orientation to use a 3-gear transmission instead of 4 and found that the 4 gear box was better. Why? I have no idea.. It might even be because it pushes the motor forward just a tad bit more than 3 gears would.

I'm in the same boat though, no B5 for me until bugs have been worked out. I can't afford getting new 'needed' upgrades and not to mention new batteries that will fit

When considering the transmission gears you might want to think about motor torque...

EricJ

I thought they did it because all they needed to do was essentially slap a Centro gearbox on it. Not that idlers are heavy, but every gear is adding some drag and complexity. The Centro had to be made like that because they reused the rear motor plate/cover. It looks like AE did some additional machining and mold making, so I can't fathom why they just reused it.

Luckily, I have batteries that fit because I've been running shorties since soon after they became popular. No squares yet, though.

The original X-6 used a 3 gear box.
The new X-6 box is 4-gear.

The rotor rotation is why 4-gear is mostly used.
The rotor in motor is rotating in same direction as in a RM car with a 3 gear box.

In very highgrip track on carpet ,astroturf maybe a 3 gear box is better.?

There are 3 gears in a RM transmission, so I don't see how the motor's torque would make a MM car require 4 gears. But I never took more than a semester of physics and have never taken an engineering class so it might just be my lack of knowledge

See, examples like this make me wonder why the 4gear transmission is better. They obviously switched from a 3gear to a 4gear box for a reason. I almost wonder if we should be switching motor orientations on RM cars to fit 4 gear boxes in RM instead of 3 gears

What do you guys think this is? To me, it looks like a location for a steering stop screw. Thoughts?

didnt the sc10 4x4 have a screw like that.

4 gears are used because of motor torque. Not that you need an additional gear to handle the AMOUNT of torque...but that additional gear allows for the ROTATION and TORQUE effect on the chassis during acceleration and deceleration to be the optimum direction for handling.
