I also saw the belt drive, but I didn't think about it.

You can curve the track so belts stay, or maybe they have another way. Also, if set up correctly, you have a belt that is a little bit stiff, so that it won’t stretch off. Just my.02That was my first observation as well. Is a belt drive as reliable at high speeds? I’d worry about the belt stretching and/or falling off track.
Belts can have less resistance I believe.I noticed that as well. What are the advantages/disadvantages of belts v. drive shafts?

@LibertyMKiii knows way more than me though.
You may be aware that the differential input bearings on any current 1/7 car die after 1-3 runs in the 180+ range. This is because of the loads they are seeing under those power levels over 18 kW.
The differential is take the power and turning it 90 degrees from the center shafts out to the axles. There is some efficiency losses there. The advantage of a belt drive system is that you are not turning the power a different direction and the loads on the bearings are different. Overall it is the most efficient way to do it. (unless you could put motors in the wheels or axles themselves and get they synced perfectly)
You will see on a belt car the motor, pulleys and axles are all turning in the same direction:
Nic Case's SR11 car based on 1/10 parts:

Yes Nic Case ended up doing 202 mph with a single-motor setup.Was that a single motor set up?
What tires was he using? Material and compound etc
I had sets and sets and sets of bearings in my RC trailer. Some got replaced in between heats (clutch and wheel bearings) all got replaced before the MAIN and at the end of the race day.Yes Nic Case ended up doing 202 mph with a single-motor setup.
His car is very narrow, which reduces the aero drag significantly. He could take that same car with today's high-power XLX2 and better batteries and go substantially faster.
But the real problem still remains. Tires that don't blow up at 190+ speeds.
Guys doing 190+ say they go through an $80 set of BSR foams per run. On average they like to go out and make 4-5 runs so you are talking about $400 for one day to run your car. + a set of bearings and any other wear items they might find.
Have you folks seen these being hocked in the facebook groups?
Looks phenomenal. I bought one more as a shelf queen because I already had a stock limitless V2 sitting around.
Little bit too spendy to consider putting it on the street.
What do you all think?

Looks like to have this body running you are looking at $500 plus shippingCool body but it really should be sold with the wing, splitter and other parts needed to run it.
Holy mother of body covers .I need this cover it's beeeeutiful when is it ready for sale?Holy Ba-gesus..
That's a Whole lot of "Potential" Custom Aero bodies..
I'm Very curious if he's really able to mass produce these and all those other bodies...
Holy mother of body covers .I need this cover it's beeeeutiful when is it ready for sale?
Or I'll have save a lot of laundry soap container s and make one
