Just started converting most of my engines over to battery power, I think I have now run more this year then all of last year (DAMN CONNECTIONS and dirty track) The esc that I’m using is a $5 el cheapo from Hong Kong they don’t come with a reverse function however that upgrade only adds $11.99 to the conversions and that’s bought from the local hobby shop that’s expensive, can do it much cheaper if I wanted. ($1.95 ea from hong kong)
I got the idea from this guy - http://www.members.optusnet.com.au/satr/2point4GHz.htm
The esc ($5)
The RX ($8 ish)
the TX - was $25 ish
The engines i use more frequently I installed servos to change directons
I installed a DPDT switch to revers manually some of the engines and the batteries i’m using are from my cordless drills so I use the clips to attach them
