How the RC system works - a video

I guess it's useful enough to belong here:

Nice review Sariel, very useful if you have any doubt about this out-of-market system.

I'm so lucky I have two 8475 sets and bring it to every Event I can assist. Always a fun race is on!

Is it possible to add an auxiliary output to one of the RC units that didn't come with one?

[Sariel]

I don't think so.

i would think so, but if you screw up you just screwed up a very expensive and uncommon part.

Recently, I took the plunge and got two sets with this system. I've got big things planned for them.

THis awesome system, really love it. The only disadvantage I found is that steering output on RC unit has small torque plus has very limited turn angle. So if you are using custom steering setup it barely able to turn the wheels.

Yeah, that's exactly why I haven't tried it. Having an auxiliary output would make the unit much more useful to me but I'm not willing to risk what I have now.

Nice review ... I was not aware of the auxiliary output. I got two of those a while back, with the Hot-Flame.

Interesting, that the video says (about the 9V remote battery) .... If you have no screwdriver, you're 'screwed' ... ????

Can't you link the two motor outputs at the right ratio so that it will go fast and have more torque?

Also cant you use one or two PF battery boxes for the RC motors? saves space and is a better shape to build around.

Um, that would work if these were two separate motors' outputs. But it's the same single motor, you know. You put load on one output, it will affect the other too.

You can even use the 8878 battery for the RC motors (one motor per battery), but you won't get the same performance as with the RC unit. The V2 IR receiver improves the performance, though.

I don't understand why it has to be two motors, the two outputs in the motor are connected by gears anyhow so surely you should be able to externally gear them back down so get close to what RPM/torque, or like a little less speed than the high speed output and a little less torque then the high torque output but still might be useful. The external gears are just cancelling out what the internal gears are going.

And what is the point? You seem to think there is something to gain this way. There isn't. Connecting the two outputs won't give you more torque or more speed than you would get from a single output. Not as long as they are both driven by the same single motor. Yes, you can trade torque for speed by gearing down or up, but it works just the same with two outputs and with single output. You'll just end up with a few more gears that do nothing.
