You remove the +/- wire (still can't remember which) from the hxp f servo connector and attach it directly to the battery.

One of the power wires on the hxp f servo should be connected directly to the battery instead of the reciever to avoid drawing too high a current through the regulator.

Sorry for any confusion caused.

It can draw too much current through the speedo's regulator if you run it from the reciever so temporarily cut your drive.

A solution is to take one of the power wires from the servo (can't remember which one) and connect it to the corresponding battery lead.

It utilises the fact that components in series get the same current and have different voltages across them depending on their resistance. This voltage is split up in the same ratio as the resistances. Using my diagram as an example, you need 12V out from one resistor and 6V out from the other (to g...

A potential divider circuit to allow 12V and 18V (and also 6V) to be obtained from an 18V set of batteries.

Change the ratio of resistances to get out different voltages.

You could also set up a potential divider from a larger voltage battery and have similar wiring to the series batteries to give out the required voltages. It involves a pair of resistors in series with you being able to clip in across them for different voltages without the mixing of batteries. If y...

That only gives you more current, batteries need to be put in series to give more voltage. To do it just wire the battereis up in series with a 0V wire from the side of the 12V battery, 12V wire from the middle of the two and a 19.2V wire from the side of the 7.2V battery Although I still think that...

It should do if hooked up properly.

Most speed controllers have a full voltage input and the servo lead seperate. All you do is hook up the battery to the speed controller (screw block/solder) and plug the servo lead into the reciever.

Exactly where and how this is done depends on the exact one used but should be a similar principle.

There is still a speed controller to go but if you are using a speed controller with a built in BEC (i.e. one of the sabertooths) for drive then the weapon controller doesn't need to supply power to the reciever so it can be pretty much any one that can take the voltage and current.
