I just picked up a SCTE with Castle ESC and 3800kv. I had castle in last year SCTE but it wasnt enough power for me. I also have RX8 with 4600kv, which I believe is the best system for SCTE. I been hearing of other motors to try and that was more reliable than Tekin setup. Any of you guys have experience with these?

Or can anyone recommend a good setup? I also was looking at the viper copper head system but it seems cheap(price wise) and didnt want to take the chance.
