Looks like a fun build!

You've got a great imagination - your Gmade R1/Capra and this both are very interesting...

Thanks! Wraith RB project was very quick work because there is almost no material work for cutting or bending. Only body panel work and battery tray working is remaining!

That's a really sweet rig.
Seems very well thought out.
I love the battery location.

Just curious, how does the battery come out? Through the front?

For high speed drive stability, I installed sway bar and also purchased Vanquish AR60 axle to make open differential. All for speed driving

Yes. Like this.
But I will make battery box lower section by cutting the current batt plate to realize low center of gravity as much as possible.
Lipo 4s power is crazy therefore set up is quite severe.

My kind of rig dude....

Very well done and thought out.

I have cut off original battery plate and made a new plate for relocation. It was a little bit tough work. I can put 1500mah 4s x 2 on this tray.

I made some modification because stability over 25mph was not good and handling under high speed range was difficult.

1. Add front sway bar

2. Front open differential/Rear spool diff
VP axle is temporary use. I’m ordering SSD diamond axle. VP axle to be used for another project

3. Longer wheel spacer (16mm) for stability at high speed range.

I also changed the skid plate and link arm to HR because previous one was like junk product (threw away!)

That looks like quite the beast! When do we get video of 4s sand spray action? Keep up the good work.
