If you google Castle 1515 you should find plenty in the $80-$110 range. I have both NEU and Castle and don't see any advantage. Actually Castle with a finned case works well as an OB without need to water cool. That said the TP 4040 is $100 brand new from TP. 4Y-1980kv or 7D-2100kv.
Thanks Mic. Been watching those on Fleebay, Just reaching out to see if there is a motor out there not being used. If nothing by two more weeks, will be going for new.
I have a Leopard LBP3674 2200KV for sale I made three runs with this motor reason for selling I decided to go with a bigger motor asking price $50 plus $8 USPS priority shipping US only....
Dang, should have waited another day. Picked up a LP3670 2000KV yesterday. Not quite the 2200kv looking for, but should work. Will keep these in mind in the next few weeks as seeing how the funds go.
