Cat 777D Mining Truck

[modelman]

Thanks for the comments guys-I decided to make the hinge pins since I could not find shoulder bolts with long threads. Some of the pins are going into aluminum so I need lots of thread engagement. I am making these now and I have a few other small parts to make. Some of the small detail work I have been putting off has to be done before painting. I need to get a radio and ESC to check out the operation of all systems and I need to put limit switches on the dump bed and that is going to be a major pain because there is no room left. I have not decided what type of battery to use so I am open to suggestions.

I have used Tamiya shoulder bolts for their kingpins with some success.
Their thread is M4 and about 5mm long - maybe not enough for you?
If interested, check parts# Tamiya 50100 and 84175.

For the limit switches, maybe keep in mind that you can have the switch either actuated by the sliding "nut" or the dump box.

Battery: Sorry, cannot really help. I'm still using my old NiMH packs and have neither made the switch to LiPos nor bought new packs in ages.

Cheers
