Finally have I been able to finish the movie of this moc and launch a topic about it on Eurobricks.









And as always you can find more on Flickr

That's very cool    Can we get some more information about it?  I notice there are two receivers.  Besides driving, what is the second receiver for?

That are the old receivers and linkt togehter to let more power from the battery box flow.
But i think Dikkie can tell you at a better way

[dikkie klijn]

Yes the receivers are linked together. The point is that each receiver is limited to a maximum of current. And when using the RC-motor with pf you need just that extra bit to prevent the security in the receiver to kick in and stop the vehicle.

[drdesignz]

Oooh, okay, I wasn't familiar with that technique.  Thanks for the answer  

[Sariel]

So, are you using one or two RC motors, and what's the gear ratio? The truck looks really good, but I think it could go much faster with RC motors.

[dikkie klijn]

I used 1 RC motor and a final gear ratio of 1:3.89. I know you can get much faster but the truck is quite heavy for it's size (1.25kg) and for the ACC we had to pull a trailer to. So I wanted to have some power left to.

[Sariel]

I see. I noticed 2 IR receivers and though there were 2 RC motors. One motor explains the speed.

[dikkie klijn]

Hmm, 2 rc motors would be nice on such a small scale  .

Well, I don't think it would be difficult to use 2 at this scale:

It was fun too see that everbody must drive a pacours backwards whit a trailer on it.
A lot off people build a to much fast truck and than drive it backwards
I thought Dikkie has problems whit his battery??  Mabey i have it wrong in mine remember.
But the ACC competions are always fun at the Lowlug meetings

Yes but yours is 10 studs longer and 9 studs higher . Wonder how small I can get with 2RC motors and 2 rechargeable battery's. Sounds like a project to me .

Yes it was empty at the start of the race  .

[efferman]

look at this and you will see how small it is possible, because with two rc motors you dont need a gearbox

[timslegos]

Another gorgeous looking truck.  Nice job.
