Plantraco 900mhz ESC/Receivers
 

These could mean a breakthrough in TTTT availability in the US! The small lipo packs connect to the rediculously small esc/rec with magnets! The transmitter has a charger "stall" for the batteries. Credit goes to Akura2 for finding this @ the iHobby Expo this past weekend. We were talking about this today and we both think it would work nicely. Pricey but amazing technology.
