Cool, so theoretically, the whole thing would cost about $20 or so?

[Serum]

what would it be like? with a stepup transformer? or with a voltage regulator? and the specifications (max current)? will it be adjustable with 5 or 6V?

David, it would be around $20 to build, as long as you have your own wire/plugs to attach it to the batteries.

Serum, it is a buck regulator with a maximum of 40v and 3amps max continuous. There is a 5v version and an adjustable version, but the ajustable version is much more involved, so I will be "content" with 5v :).

So are you going to try out this idea?

[MetalMan]

I already have. As far as I can tell, the regulator will work (it does with bench tests), but I don't have a controller to test it out with. The question is, do you want to try it out :).

Couldn't you just try it out with a brushed controller? All you're looking to prove is that it gives voltage to the receiver and electronics and junk......sounds fine to me. :)

I could try it out in my Rustler with an EVX and a 12v motor (not the Johnson one), but I feel like doing that as much as you feel like working on your TF :). Maybe later today, but I got a bunch of homework and stuff to do too.

Hey hey, I got the TF running, and running great! Now, if you'll just take after my example....;)

I did yesterday morning :). I got pretty bad glitching when the car was about 30ft. away, but I am not sure yet what caused it. I also had bad throttle movement, which was either caused by the glitching or LVC kicking in with 4s Lipo. I did have the regulator right next to the RX, so that is the worst possible case for glitching.
This setup was terrible, though. The EVX and batteries weren't actually mounted, they were only sitting on the car. The next time I do this, I will do it right with everything mounted up and with the batteries charged to eliminate LVC problems.
