Limitless Dual Motor Limitless tp motors scorched full length chassis

[vwturbowolf]

Made some really good progress today on this car. Made the two pieces for the front diffuser. Both esc mounts are made and battery strap hold downs are on. Made the front shock deletes so they are just tie rods.

Went back thru and remeasured the weights of everything. All in the cars weigh 18lbs with. Let and batteries.
11.3 for the car with tires(not shaved down)
1.2 body
5.5 batteries

I was hoping to keep this damn thing around 16lb but it’s still a tank.
But I also remeasured my buddies dual 1100kv castle motor setup and his car actually weighs 22.8lbs with everything in it, so comparatively I’ve got a huge weight advantage. 22% lighter.


Tomorrow I will route the wires and receiver

 

[vwturbowolf]

trying to keep the wires as clean as possible I decided to run both esc wires up front and put the y harness to connect both esc’s together inside the body mount pieces. Actually made a very clean setup this way keeping wires hidden away.


Few items left on the to do list:
Adjust esc settings and calibrate esc’s
Set servo arm at 0 point and connect to linkage
Cut down new foams

Looks amazing, I love the ESC wiring layout!
If I may advise something.... The speeds that this car will go, you should look into the aluminum body mount pieces from GPM. That plastic one will flex.

It is really funny you mention that. As we speak I am mocking up a piece of carbon to replace the stock pieces that would hold them more rigid. Plan to use a flat piece then glue parts of the holders trimmed down to the underside of the carbon sheets. I wanted to see how this worked out before ordering the aluminum pieces.

I’ll post a pic soon.
Great minds must think alike

Working a few ideas around still but it’s getting there

Alright so more work last night completed:

All bullets soldered on esc’s and second motor

Both esc settings programmed(I may have to reverse one when I set the throttle)

Tonight’s project will be to calibrate each esc then hook them to the y harness to confirm they are linked good.
Tomorrow night will be the first run with it

Ran the car on the bench and it is ready to rock.

Super excited to see if my hard work pays off with this.

Tomorrow I’ll be running this, my hobao, and possible my carbon vendetta if I can get it back together. Should be a good day

Here’s the first test runs

4s pass with Onyx packs
144mph

7s pass cnhl packs, let out at 97% throttle

I heard it...but I damn sure didn't see it!! LOL That thing was moving...

Just gonna put this here, to show a few things.

This was the full throttle portion of my 4s pass using the Onyx 8000 packs.

Few things to note.
I made a 144mph pass requiring just 3966w out of each motor.
Average voltage during the full throttle is 15.4,
The batteries were charged to 16.8( 91.7% efficient)
Lowest drop the batteries had at the peak amps/load was 14.9 before quickly recovering to gain up to the 15.4 average.

This setup as a whole is so much more efficient then I could have ever imagined.

Beautiful build bro, I too am in the process of doing something similar twin motor setup with my Hobao GTB. So far I've switched to a scorched carbon fiber chassis and made a custom made twin motor mount... still long way to go! Just one question, was load evenly distributed on both motors? Did you notice any temperature differences between them?

Pretty much the same. I noticed one set of batteries were topped off a little more then the other set.

One motor 383 amps 29.5start/ 25.4 min 9737 watts
Second motor 370 amps 29.2start/ 25.1 min 9403watts

Awesome results man! The dual motor setup is the way to go
Pretty sure I'll be doing a dual motor build over the winter...

My main goal was building it as lightweight as possible and everything seems to have worked out well. I spent a ton of time planning this build. I think the power to weight is keep so it doesn’t require as much power to move the car

Weight certainly is a consideration. Seems to be no replacement for power given how well these dual motor builds run....

At some point having 20k combined watts will do it

I see that you ended up using the new monster servo instead of an AGF.
Also, I was wondering where you got all your carbon fiber parts other than the chassis.

I make everything else.
And yea the Agfrc servos are great, I figured I would try the PP one for like 15$ more, I’ve gone thru a couple servos lately with crashes,

Even the shock towers?

They were scorched ones. I usually make most of my wings and diffusers

Here’s some Videos from the last session and numbers from the last two sessions out with this car. Slowly progressing to higher speeds.
