Hi guys.

Am I in another minority of one in still being into lego?

Anyway I'm building a 4x4 that I intend to motorise.axles are done and I have a basic 4 link suspension but whilst it is giving compression and droop there's little flex. Am I right in thinking I only need the links to rotate at one end to rectify this?

Cheers.

Tried that. Waste of time.

Next idea; split the chassis link mount it two and pivot in such a way as to be able to rotate. Difficult to get power to each diff through conventional props any ideas?

mine has ball joints at the end of each link and an a-frame on both ends. The problem i had was the lego shocks are more for show so i just put them on leavers so they drooped loads but the vehicle sits at full bump all thmd time. I also found diofs are a waist of time the spider gears always broke or the difflock would pop out, so mine doesnt have diffs. Aconventional transfer box with props but going to a worm gear on top of the axle which drives the crown wheel. Thats the other problem youll have, unless you ok with having a massive diff case you wont get the crown wheel and pinion to mesh when you drive it over stuff. You just get a clickclickclick as something starts to lose teeth. But then again. No diffs isnt a perticularly good idea because you may get loads of traction but i have broken UJs and if that doesnt happen the wheels spin in the tyres. Hth, holla if you need to know more.

Very cool. I feel I'm at a disadvantage against that as I'm not using new series parts, I'm on the older stuff at the moment,at least till I weaken and butcher my extreme cruisers axles . I like the idea of ball joints. I feel a trip to eBay for bits is imminent.

oh wait i lie, i have an open front diff. Must have changed it at somepoint, maby to get a better turning circle. Mine is 90% old lego technic, the only new bits are the indipendent suspension wishbones i used for the links.the steering caused loads of headaches, the strongest way to do it i found was to get the power functions linear actuator. It works like a double acting hydraulic ram. The motors vary too, ive got the big one in atm but i found the smaller one was a bit faster.but it will burn out with prolonged use.let me know if you want more pics. It is a bit lame i know but it is a lot of fun when you get them going lol

It's no good this is keeping me awake of a night having cunning plan after cunning plan. Solution, rebuild my old models from the 80's assuming I can remember which I had to be able to download the instructions. Auto chassis was one, pneumatic excavator another and the jcb and the test car and.... You get the picture. Good few nights away from Satan's evil sister and the tv. All good.

lol i have a half built jcb i got for the anger management, but the weight training took over and is slightly more productive 

[lambert]

Not so much anger management for me as it is a boredom relief tool oh and an excuse to visit the man cave in my loft.

I love Tecnic Lego its ace. In my youth I learnt alot from it. Gears and cogs screw threads ect ect... best toy kids can play with... Non of this PSP or Xbox360

And there was me thinking Rich was the only one!
he's made all sorts with his lego which consists mainly of the older style technic stuff.. And in fueling this habbit i have been slowly buying him new sets to help get the bits he needs recent additions have been a new motor and bits and the recovery truck which Santa brought him.
