But I've got other projects in line ahead of that.

Re: Bolink Digger sort of
I did some wheels a while back for F1 tires. They work well with the 21t brush motor

The wide 5 pattern wheels looks cool, and scale.
Always looking for new and interesting ways to waste money.

Re: Bolink Digger sort of
Yea I had to replace it with a better one with holes closer together , made a kydex plate to adapt it , now it's steering pretty well even on a damp roadjuicedcoupe wrote: ↑Fri Jan 28, 2022 5:51 pm How bad does that star servo horn throw off the steering geometry? I always try to get the ball cups as close to each other as possible.
Next is to fit another shock to the rear , right now she's not so much a Digger as a Skippy the bush kangero
If a jobs not worth doing then its certainly not worth doing well.

Re: Bolink Digger sort of
In a normal buggy you would be running an overall ratio around 8/1 to 10/1 for a low turn brushed motor. But of course a normal buggy is a lot heavier than your diggerDadio wrote: ↑Wed Jan 26, 2022 1:04 pm Next question is what kind of gear ratio to use , I was using a 13t pinion with a 54t spur giving 4.15/1 , it felt over geared so on instinct I ordered an 11t pinion to give 4.9/1 , that still seems high to me but I've never driven a rig like this , anyone have a pointer on gear ratios for this with a 12turn motor ?

Re: Bolink Digger sort of
I worked out a damping solution for the rear , excuse the cheap shock but it's what was laying about , works well with much improved rear end , now I'm running out of space in my road for testing , too many kerbs and not enough straight so I might take it to a nearby car park today to open it up a bit , that is if the migrain I have lifts a bit

Re: Bolink Digger sort of
Got the front tires trued and made up body mounts , I've not cut this shell only made a single rear body mount hole , it nearly broke me looking at the way the front body mount holes are unevenly drilled , I had to make up wonky mounts to match , on closer inspection the body is marked as a PB body anyway , I went to test it with the trued tires and body fitted and the battery went instantly flat if I get a chance I'll have another go tomorrow . Also got to my local screw shop and finally picked up matching screws all round

Re: Bolink Digger sort of
Oh my that test drive was disappointing , Just no rear grip at all ,really have to feather it off the line , at least it steers now but man do I need pointers on Pan car suspension set up ! Or I just need to fit buggy tires to it , I can see obvious problems up front as it has single wishbones and tires that need to be flat on the road , my instinct was to give it some droop but I'm not so sure now , maybe harder on the springs and use adjusters to have the arms flat without droop ? Anybody got any tips as I need help

Re: Bolink Digger sort of
I found reasons for some of the rear traction/stability issues , firstly the rear pod bulkheads had cracked around the bearing seats for the rear axle leaving the axle unstable , also the grommets used for the lateral pivot of the rear pod were not sufficiently compressed also allowing the pod to be unstable in its alignment .
The pod bulkheads were 3d printed in polycarbonate and they had both clacked so for now I've reprinted them in PLA , not ideal but hopefully less brittle , I've also compressed the grommets more to make them more stable .
Up front I've stiffened it up and eliminated droop , hopefully this should help the handling but I can't tell as it's wet out today .
