Yes, I got another Lazer ZX, MOTHER...

Unlike the other two, this one looks and feels like somebody actually took care of it. Suspension doesn't bind, differentials are smooth, hinge pins don't appear to be bent, not all gritty.

The amp draw goes hand in hand with temperature increase , its easy to wind on a lot of timing to make a motor run faster but it gets very hot therefore inefficient and the motor cooks and dies , there's a sweet spot with timing where it increases rpm without drastically increasing amp draw , the tr...

Finally got around to restoring this....body still has to be done. Went with a new vintage Parma wiper speed control with brake and scored and original M480RS motor....this was me and the Diamond One's 1st ever rc back in 86' so it's way up there on our list Resized_20220717_130613.jpeg Resized_2022...

15mm longer arms and the gearbox is free floating :D need to make a panhard rod to stop lateral movement , top right arm is pretty close to the motor so I'll move it outward 4mm at the axle end , the arms came out more parallel than I planned anyway , the JRX2 arms flare outward more and that's the ...

Got some Crusher parts from Germany today, and upon removing the body from the box I noticed it was quite heavy. Someone made a fiberglass body and did an amazing job. From the outside you can’t tell at all

A little silent movie of the rear suspension , the Panhard rod is some old butchered parts I had laying about but I'll model one up for Thingiverse . There is a little lateral movement that I tried to show at the end of the clip , it's caused by the arm flexing , as this is home printed I kept the i...

Just thought I would park this here heh.

Got the hopper body fitted , needed the cutout for the motor elongated , also got some temporary front shocks fitted , really crappy WLtoys A959 shocks but the fit is good as is the spring rate . Just got to fit some electronics and I can give her a whirl. :D IMG_20220725_210131_218.jpg IMG_20220725...

Little video , still hopping I'm pretty sure its just over sprung , it bounces on a static drop , could be the tires as well , the front is working well though .

The design of these buggies with the motor and gearbox hanging from the shocks does result in a lot of the buggy weight being unsprung weight. The shocks really can't do anything to help with it. The rear tires are the shock absorbers for handling the bouncing due to the motor and gearbox weight, an...

On eBay, there's a set of Parma carbon rear axles, but I don't know that it would give enough weight reduction to make much difference. I think the gearbox configuration is the limiting factor. Maybe something could be done with softer compound rear tires to absorb bumps better. . Screenshot_2022072...

Another video with the WLtoys A959 motor , think this is the sweet spot .

That seems like a proper Hopper. Nicely done!

But if it had that brushless motor....

There may be one coming next month on the slow boat from China
