I've been wanting to scratch build a large scale buggy for some time and have made a small start.

Inspired by VassilisG's diff;




I made one of my own;

We will see how it holds up without the thrust bearings.

Eventually I hope to end up with a buggy that looks a little like a cross between these two, which are my main inspiration;





Cheers,

Kevin

Fantastic work!!

Vass has moved to Vancouver then!!
Wondering why he was so quiet!!

In case you're wondering, it's a compliment, as Vass has been doing some equally astounding engineering work on other threads.

I vote you build a Monster Jam truck!!

Thank you very much for the kind words.

Mooman, I didn't cut the gears, they are pretty reasonable from https://sdp-si.com/eStore/ But I'd be happy to help you out with whatever I can.

Al, yes, Vaas has set the bar pretty high and has been a huge inspiration for me. I'll be happy if it turns out half as nice as his projects. I thought about a monster truck, but 4x4 would be quite a bit more work.

It was finally being able to get a cheap and powerful servo going which really allowed me to go for the build. As shown here; https://www.largescaleforums.com/showthread.php?t=17345

I'm in the middle of some renovations at home so it will be hard to find the time to devote to a new project. But we will get there, one piece at a time.

Thanks!

Thank you Vass!

I have been following your projects for a long time and finally can get going on my own.

The turning was done manually but the pocket in the housing was machined with a CNC.

Scratch Built Buggy

Thanks WoodiE!

I've been playing with the front end design a bit. Below is a 3-d pdf.

If anyone has some advice or could point me to some good literature regarding steering geometry, IE; avoiding bump steer, Ackermann angle etc, I would really appreciate it.

For a servo saver I was think of having a shaft, free to slide in a housing, mounted to the horn, centred by some springs...

Edit; The pdf is too big, here are some pictures;

Here is the general layout so far. Maybe shorten the front swing arms and widen the frame a bit?

top%2520render%25202%2520RC%2520Buggy%2520.jpg

The wheel centre's are 48 inches long and 33 inches wide. I've got a 70cc Honda copy for it but it will be a while before I can do any cutting and welding...

Cheers, KB

Al, I thought my mechanic in my avatar would want to go for a ride, but after printing out a full scale drawing, I'm thinking I could ride it!

I think you would have to call this half scale. This might be a bit ridiculous for size but will be fun to build. There could be some liability issues if it ever went out of control...

That's a T-Maxx for scale;

What you you think?
