I did some searching and didn't find much info so hopefully you guys can help me. It would appear the 510r is just a rebranded Hobbywing and in the Hobbywing description it mentions being able to run a fan off the programming port, can the same be done with the 510r without damaging it? Also, will the programmer from the 510r work on the Hobbywing?

Yes you can run a fan off the esc port no issues. Not sure about using the 510r programmer on a hobbywing esc

Thats kinda what I figured but wanted to be sure. I went ahead and ordered the hobbywing programmer, for all the more they are it's not worth messing with.
