Modular truck

[jorgeopesi]

I had the idea of trying to do modular parts to create different trucks. My first goal was to do something simple and strong and I did this, but then I thought if I want something simple maybe I would have to remove the ackermam steering... it is hard to try to build simple... Anyway I got a low RC chassis with a lot of room above to use for different truck types and taking away the ackerman system it would be simplier... While I take a break of the 959´s bodywork I will try to do modular axles, lately the thing I like more of technic is optimization much more than complexity.

Interesting idea, but I'm worried about amount of slack in steering...I hope to solve similar problem using universal joints. Until mid of September hope to make simple and stiff chassis to test my solution...

I do not think so, maybe a little but not enough to worry about  .

Cool build

I'm curious what you have in mind, but will one L-motor be enough for driving? ;-)

I like your solution of placing the motors off-centre, outside the chassis. But the extra gearing creates more possible weakspots, especially with a full truck configuration the drivetrain might struggle with weight (torque stress skipping or wind-up)... The L-motor immediately goes from 0 to max torque (contrary to XL, which has sort of a starting/stopping torque curve). But it is all nicely braced though, compact scale and not built for racing, so you should be good. Nice compact ackermann steering system too!

Using the right gears almost every motor is enough  , anyway I have room for a XL motor if I need it.

You right and that is why I want to use a clutch in the drivetrain and cause my children will break the gears without it, I do not think the weight will be a problem I do not usually do heavy MOCs.
