I am converting a T-Maxx into a gasser with a weedeater motor. I want to run a 6 cell 7.2v battery instead of 4 AA's so that i can just recharge and go. What is the easiest way to go about doing this? I have a couple of old speed control's I could use if i need them.

Im thinking I can plug my ESC which would be fed off a 7.2v battery into the "battery" plug in on the reciever, and just plug my throttle servo in where it would normally go? Is this right?


Im a little rusty on the electronics side of things, so what is the best way for me to get the reciever to run the throttle/brake, and steering servo off of a 7.2v battery? thanks

your reciver will run off battery's anyway so just get a 6 cell pack, change the connecters to a 3 prong reciver plug and then plug in your servos.

So an extra 1.2 volts wont hurt my reciever or servo's? That is simple enough if I can get anway with doing that.

That extra voltage will hurt the servos. Run 5-cell, maybe a sub-c pack.

I was afraid it might. I really dont want to mess with the pack though. I have an old Duratrax ESC that is dead, but still runs everything else fine, so that is what i will end up using probably. Unless i find a better way that doesent cost me much.

A 5 cell pack would be ideal. If your charger can take it you could just unsolder a cell from a 6 cell pack.

My second choice would be the [link=http://www.horizonhobby.com/Products/Default.aspx?ProdID=CSECCBEC]CC BEC[/link]. This little gadget will take the voltage from your 6 cell pack (all the way up to 20 cells if you want) and keep it at a steady voltage. The voltage can be adjusted using the castle link (same one you need for many of their ESCs), so you could set the voltage at 5-6v or even 7v if you want to push your servos a little. Its a great deal for the price too.

If you have an ESC laying around then yes, you could plug the 6 cell pack into that, plug the ESC into the battery jack on your receiver, and plug your servos into the receiver. Seems a bit bulky and ghetto but it will work provided your BEC can provide enough current for your servos. What servos and ESC are you planning on using?

Yes, it will be a little ghetto, but then again, a 5lb motor on a 24" long truck is ghetto to begin with. I may change it later, but I just want to get it working for now. I have a Hitech 945mg servo for steering, and a 2055 traxxas for the throttle/brake. The ESC is a duratrax 16t intellispeed. Nothing hi tech, but i want to get it working for now.

That little gadget you have the link to is really neat though. Maybe when i get this truck how i want it, and want to clean it up some, ill buy that. I think I can hide the ESC ok right now though.

just get a [link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXHFP5&P=ML]revo reciever pack[/link].
