4WD Lunchbox drift van project

Recommended Posts

Hi all

Had a Lunchbox shell left from my “Mini Lunchbox” build, and have been interested in building something more custom. I also have some impulse purchases in need of a home. I have seen a build using TA02 drive trains and M03 suspension, also videos trying to fit a Lunchbox shell to an M08 I think and a great M03 4WD conversion doing awesome drifting. So all that leads me to this.

Still working on the mock up of front and rear, front is done. Still tinkering with the rear. Shock towers are custom aluminium as will be the chassis plates as they need to be 207mm wheel base for the body. Going to give engine turning a go on the aluminium as I now have a pillar drill 😀

Finished mocking up the bottom plate for the chassis today, just the top plate to do. It’s going to have to be larger than planned as I still need to place the esc and battery (a shorty hard case Lipo I have on order).

Made a few more pieces today, top deck to hold the battery. Body mounts, wanted to use the alloy lunchbox mounts as I can then make use of the holes already in the shell, still need to mount the front bar. Ordered a motor from hobbyking too. TURNIGY TRACKSTAR SCT 5T SENSORED BRUSHLESS MOTOR 4150KV.

That's a very beefy motor! What pinion are you going to be using for the 5mm shaft?

Lol, plan B cos motor is a lot bigger than I thought. Put it aside for a future project (possible monster truck build or crawler ) going back to the 13.5 I already have.

Finally finished mock up, body is mounted using lunchbox mounts, still needs a bit of tweaking. Front is a little to high and need to trim the front wheel arches a bit, front edge and bumper are in the way.

Top deck is finished it will hold the shorty battery. Next step is to tidy up all the aluminium plates I have made and give them a brushed finish.

Trimmed the body today, trying to cut as little as possible as it’s a hard body. Don’t want to cut too much. Going to wait to cut any more until she’s running clears atm. Made some bump stop for the rear as chassis bottoms out, not that it will, suspension is quite hard on purpose.

I have finished chassis plates, now to start final assembly. 
although still need to make a drive shaft, still deciding on steel alloy or carbon fibre. Not sure the first 2 will be strong enough.

Really happy with the fit, even happier that I didn’t c@ck it up 😀

Soldering also done, not a bad effort for a first try.
