Does it have a gear box? Very nice work.

No gearbox in this one. That's not needed.

It has an adjustable slider clutch and the engine originally is built to move around 150 kilos in go-kart with driver. This one weighs approximately little over one third of that.

Started this one late last summer. I didn't do it at all during December and January. Not so long, I had it clear in my head once I had decided to build it. I first fitted it with a 50cc tuned engine but figured that to be too tame and upgraded to this engine (downside to that was that I needed to completly redo the driveline). 50cc got off the car with no use at all. The car has never been driven yet.

Very nice! Definitely a quarter scale legend!

I cant believe how much of this thing you fabricated literally from scratch: the entire frame, the chain drive train, the pipe, and even the body!
(BTW, can I bum a smoke?)

gorgeous rc

you must have spent loads of time at that.

i would have to see a vid of it running to be convinced about the running gear though and how the complete package works together..

any vid in action?

besto luck.

Thanks again guys.

Dc2 man; no videos just yet. Will get there eventually and post vid when I have the footage. Still some preliminary preparations, like breaking in the engine.

WICKED! that thing is beautiful [X(]

Love the paint scheme too [8D]

Just wondering, what material did you make the rear drive cups and axle pins from?

Absolutely stunning craftsmanship! As a former metal fabricator I can safely say your way better than I ever was ! It might seem redundant, and I dont know if youve installed one or not ,but I would highly recommend a killswitch. It would bring me to tears to see this beast damaged because of a runaway.

Thanks again guys.

Sam, the cups are machined straight out of a kart rear axle so I do not have exact knowledge of the material itself. It does have some spring steel characteristics in it, yet also some softness. Axle pins and driveshafts are made out of weldable acid stainless steel. Very hard material but according to material certificate, not prone to crack easily.

Obeast, failsafe is there and very soon there also will be a remote controlled kill switch, now there's only a manual one.

sam123, these are links to the vids, just click them and the videos should start playing. If you're still having issues, then it's probably a plugin issue or something.

You have got to post that vid once you actually run it on the ground!
