Jambo Tungsten carbide loses to a fatty basher...

[american0831]

When I noticed my fatty boy like to break the Stainless steel pivot pin, then I know its time to try the new material what I found - Tungsten carbide rods. it was a very hard works, but it makes me excited, I look forward to the results I want. really extreme stiff.
yeah, today is the first time for first jump, this is a nice 3 circle backflip, not bad landing, then it fall down. it was my turn to stiffen this time.

(next pic)almost 8.5 kilogram

Iis that result what was meant to happen,? or Its just wrong material?

8.5KG!? A stock Jambo is 4.8KG. What did you you do to it?

Well...actually I'm not sure, here are my parts: 6+2s 6200mAh Li-po, HW MAX6 G2 + 4990SD motor, 63v 4700uF*2 capacitor pack, F/R diff metal gearbox, and some upgraded aluminum parts (shock towers, turnbuckles F/R CVD, etc...), the wheel part is ZD racing MX07 188*103mm, thats all. I think mabye that problem from battery and ESC?

My guess is that the wear there is in the A-arm (see pic) lead to the breakage of the pin. If with a new A-arm and hinge pin does not resolve the problem I’d try to make your Jambo less heavy.
With all that substantial additional weight you should also check if your shocks or not way to loose (heavy chassis slaps after jumping) or stiff (hardly any movement).

Maybe I found a possible direction to solve this, about shocks setup that eliminates bottoming, the vehicle never bottoms out when I flat throwing, I thought that was ideal setup before, so maybe I should to try different setup about soft shocks.

In such a heavy vehicle, what do you expect?
