After many years of wanting to pull this off. And finally actually starting on it. I am now to a point to where I feel like I can show you what I've had envisioned in my head. I'm still a little ways out. Couple more pieces to fabricate. More parts in the mail still. Temporary hardware just holding it in shape. The reason I chose FWD for a top speed car goes back to my experience with my old Tamiya FWD new beetle. After getting bored with the car I would stick two stick packs in there wired in series, throw in a 10t mod or whatever it was. That thing was a missile that was so easy to go fast in a straight line with. As long as I was on the throttle it went straight as I wanted it to. So that leads me to this car. But ill let the pictures do the talking.
And some of the behind the scenes that I've been holding back on posting till I had more to show. The cardboard rectangles represent the battery placement. I will have a litte holder and Velcro that hold them in. The plan is start on 4s and move up to 6s.
And the chassis cutout. I've cut little parts with a dremel before and it was kinda time consuming. Not this time
Thanks for looking guys. I'm really excited about this project. Just wish I didn't start on it so late in the year.
Looks great! If you ever get bored with fwd just add another trans and motor
I always wanted to build this:

It's time to stand up to the bully. Support the companies that support the industry, not the ones that tear it down. Say no to Traxxas Factory Works website
The motor is a 4600kv. It's max rpm is 100,000 rpm and 6s technically achieves higher. But I know the aerodynamics will be holding the car back before I reach those kinds of RPMs.
And when I was cutting this, I can't tell you how fast and smooth the cutoff wheel went right through this stuff. I would guess it took less than 5min to cut the chassis out. I do still need to do a little filing inside the front suspension openings. But the long cut looks and feels just as smooth as the factory outer edges that the sheet came with. I also was expecting a little chattering or hopping. It literally slid right through like it was cutting butter.

I hope you were wearing a mask when you cut that carbon! Not that I really have any right to talk, I don't wear one as much as I should.
I held my breath as I was making a cut. That works the same right
4S is gonna toast that can in short order, 6S even faster. Per a conversation with the manufacturer, those Castle 540 motors are designed for 2S, can handle 3S in lightweight applications. ESC is irrelevant.

I knew the can was technically a 3s max. Guy I got the advice from when purchasing the combo ran his on 4s all the time with no issues at all. The 6s was a plan if the 4s doesn't achieve the speed I'd like. I honestly don't know much about these motors but I don't plan on bashing like some would in a big heavy vehicle with big tires. My temps should stay relatively low making 10 second runs every 10 min or so. Ill be surprised if the car goes past the 4lb range. With the higher gearing on 6s the load will also be less. We'll see I guess but you may be correct.
The problem of using a higher voltage than the motor is rated at is nothing to do with the load on it from the gearing and chassis weight, but entirely due to the maximum speed the motor can run at. Spin the motor at a faster speed than it is designed for and you can end up with the rotor magnet attempting to escape the can by going through the motor windings. It is why Castles 5700 motor is their 'fastest', because while they also make a 6900 and 7700 motors, running those on 3S like you can with the 5700 would destroy them.
The 4600 motor on 6s is 102,120rpms. The can has a max rpm of 100,000. I highly doubt I would max spin the motor while the car was driving. On 4s it would only be running 68,000 RPMs
Been slowly working on the front end over the past couple days. Got a couple packages in the mail today. The body came from an ebay seller who does all the work, I absolutely hate trimming and painting bodies. But he applied every decal too so I have to remove the residue still. Here's a couple updated pictures of what she'll look like for the most part.
No clue what standard 1 battery touring cars weigh but I threw it on the scale to see about where ill be. After its all said and done it will still be under 4lbs
I have never actual weighed it, but I think my TC5 is about 4 lbs, give or take. That's with a 5800 2s2p and a fairly heavy body. Body is probably half pound by itself.

Just wondering how I can either measure or estimate my top speed? I have a mamba max pro, 8400 mah ni-Mh battery and a 4600 kv motor, full bearings.

I honestly don't know because all the top speed runs I've done were without a shell OR a wing. I'm wondering if I took off the springs and just let the car sit lower to the ground if that would help too. Hmm...
I found my cobalt 12T motor for my voggard T10 on road project. I want to get the most out of it top speed with out going lipo. Can I get some info on what would be a good esc and battery combo to go 45mph or more. I was thinking of a novak T4 and a...
A friend and I started building a car for top speed runs. While researching esc's I noticed most of them have a 3.5 limit on motors using 2s or 6.5 limit if using 4s.
My question is if everything else is the same (gearing, tire size, etc) would a...

Regardless of gearing, horsepower as it relates to electric RC cars is a function of motor & battery. How much power you create is dependent on motor & battery. The most powerful motor will be a gutless wonder with insufficient voltage pumped into...

Ahh yes, that was part of my plan but you beat me to it.
I knew the standard shocks and tower wouldn't fit under this style body so I had a few alternative designs in mind. The car doesn’t really need suspension, just a little flex in my opinion....
Will the top shaft of the B4 transmission fit in the Team Car? I want to use the B4 top shaft and B4 slipper setup in my team car. Does anyone know if this will work?

no, get the shaft and the slipper setup and ti works, no problem.
