The Best Way To Remote Control Two Buggy Motors

[trekman]

I'm just finishing off a MOC and I am using two buggy motors for the drive. I would have liked to use an IR remote and the receiver, but I have noticed that the power to the buggy motors is not what it should be, especially compared to the Lego 9v mains transformer which I use. Is there anyway around this without modifying the protection circuit in the standard PF battery box. Would the rechargeable battery box work any better, or would it suffer from the same overload protection when using two buggy motors? I am using a buggy motor on each rear wheel and a M motor for steering.

The best thing would be to use the radio transmitter and reciever found in sets like 8475 and 8366. they have an internal servo for steering and an auxiliary output if you still want to use the m-motor. Other than that i would recommend using two battery boxes and two v2 recievers, one for each motor.

^ I agree; the buggy unit is pretty compact for what you get. And I think even with V2 receivers, you'll still run into the current limiter-thing.

I have one of those, and initially considered using it, but it wouldn't fit my scale or track width. I think I might just use a wired system, attached to a handheld battery box or train transformer, which is what I am currently using. It is a bit restrictive, but at least I get the right sort of power to the wheels.

And good luck trying to keep up with it...

Depending on the size of your wheel tire combination utilizing IR will be very hard. It has more to do with the range of the IR controller than the power available. The vehicle will quickly outdrive the capabilites of the control link and you will find yourself chasing the vehicle. I hope you can run.
