[TC21] Build something

[msk6003]

Max 3 motor is not so obstacle to me. Insted, I can't think what kind of vehicle will good for contest. In google search for 'transformation rc', all of result is some kind of chinese RC which transform using simple 4-bar linkage.

But I want something more difficult model than that. At this time, someone in my local community give me some link. And I think it will good for this contest.

LEGO IDEAS - Mach Patrol

This is original model. It is system build but looks good and I think folding front wheel is good idea.

But wing extend from front wheel assembly is to complicated, so I remove it and put another function insted.

I haven't decided the name yet and If I get another idea I will smash this and rebuilt. If I can;t get other idea, this is my entry.

Anyway, I want use C+ insted PF in this time. Because spike's medium angular motor looks good for make some hinge point.

So I use 2 of it for drive rear wheel and 1 C+ L for transformation. Basic concept is car transform to plane like original idea.

Even it is still not finished(need to make rear and front light) I build this in 1 day so don't have WIP picture.

I use 3 mini linear actuator for folding front little caster and rear drive motor and 2 worm gear for folding front wheel section. Of course gear ratio in both actuator and worm gear is different so I use simple linear clutch in worm drive module which looks like side mirror.

Front wheel use new 5L wheel-kind part introduced in minions set. Rear wheel work as both driving and steering so front wheel need to minimize to friction for work smoothly.

My most problem is C+ hub's height is to high but can't use other thing.
