maybe this is just me, but I would definately take something with 3 channels if the price isn't that much higher.
you never know what you might need it for

Maxxrickard · 11.27.2009, 05:32 PM

maybe, but what can i do with the 3:e channel?

Shift servo maybe, if you ever wanted to try the 2spd upgrade. Or, maybe if you get a little pico-switch (r/c on/off switch), you could use the 3rd channel to turn some lights on and off, or maybe a horn even!

I like that last idea- useful sometimes...

ha ha thats funny! where can i find a horn?whats i pico-swich?can i turn the car on/off?

For a horn, any little buzzer you can buy from somewhere like radioshack would work, something like a 5-12v item would work with this:

Put a small ~9v battery on one side, and the buzzer on the other, then you can turn it on and off via the rx.

You wont be able to turn the truck on and off though- the rx needs power in order to control the switch, so if you switch the truck off some how via the esc = no power.

For lights, you could either use the picoswitch above + some large LEDS, or use the item below for a simpler setup:

hmm dont get it. dont i connerct the switch to the reciver?isnt the switch the horn?

The picoswitch is just an on/off switch in itself- you plug it into the rx to control it. You have to connect up a horn and battery to the switch itself, then you can turn it on & off- rather like an esc; the esc does nothing on its own without a battery and a motor.

Just swap the lightbulb for a buzzer in this example diagram.
