Because the 1515/1d has a High KV suitable for 6/7 cell or 2s but is too big and heavy for 1/10th scales and you would need a huge battery to utilise its current capability, the only use i see for it in cars is for speed record runs.

I also like the mega motors, i have 2x 16/15/3s, a 22/20/2, a 22/20/4, 2x 22/30/2, and 2x22/30/3, never had any problems with any of them, Lutach is right about the amp ratings if mega say its a 60A motor it can pull 60A all day long without getting too hot, if you but more load on it it will pull more amps without a problem, the 16/15/3 are rated at 30A and i was pulling about 45A continuous in an EDF plane for the 2.5 mins the battery lasted without an issue.
