ESC or battery problem?
Hi all,
Hope you can help - my YZ-2 feels like it's lacking "push" - it feels laggy if anything compared to what I asked it to do via the transmitter. Steering is absolutely fine. Tx- Sanwa M12 so defo fast enough RX - Sanwa for M12 (at work so can't remember number) ESC - Orion R10 - punch set at 8, boost at 10, turbo on Lipos - Orion 4500 carbon looking ones shorty's Whenever I'm getting back on the throttle the car just doesn't seem to pick up and go compared to others. I'm on a 22T pinion for a standard spur gear. Also find that my fastest lap is usually one of the first 3 in qualifying by about 1 second over a c. 20s lap. So I wonder if it's the cells are getting to the stage of being worn out as they are well over a year old and been used very regularly. The esc is slightly older than a year and likewise gets some good use. I have checked to see if the capacitors "smell" at all in case of burn out. Nothing. Any help before I find myself replacing the esc and the cells all at once which is obviously a pricey way to fix it by buying it all new. Thanks

Is the motor reasonably new and has this done it forever or just started doing it. Could be gearing, lipo or motor.

The motor is relatively new (3 months max) and no certainly seemed to offer more before. There has definitely been a "change" of some kind
