Hello,
RC car motors pull a lot of current, from 2A to 8A. The L293D
chip goes up to 1A peak (for some miliseconds) before it shuts
down.
I suggest bypassing the L293D chips and using something like
the LMD18200. <http://www.national.com>
Good luck,

| After not doing anything with my HB for a few months, I decided to buy a cheap RC car and use it as a platform. Anyway, I get a car that takes 6 AA batteries because I figure that the main motor is probably 9v (maybe that was a faulty assumption). (...) (27 years ago, 9-Nov-97, to lugnet.robotics.handyboard)
