Well, I got a voicemail saying that the 36-60-2000 is out of stock from rchover.com, I still have to call back. Do you guys think the 50mm 2200kv motor would work well in an RC8 on 4S? I'm thinking I'd like to try it but I'm not sure it will stay cool. Even the Neu 1509 is 53.3mm long, while the 1512 is 60.9mm. What do you guys think?
