Hi Todd,

I believe they are replacing them with almost identical motors but with a slightly higher KV value. If you can source those then they would be a drop in replacement.

If you're interested in something else, then here's some that I've tested before. The only thing is you'd need to solder the 3 male 2mm bullet connectors onto each motor. Otherwise they're drop in replacements.
