In any case I learned a valuable lesson on how dangerous these fans become if they let go!
I also learned any test jig when spooling up the motor/fan, the fan shroud should be fully supported like it is in the plane or it will bend and distort and cause a blade strike too.
What's your set-up? Still have the stock exceed fan/motor, just plug her in and go. Not super powerful. (you may have it if is enough fan/motor for you)
I'm determined to get this Change Sun 10 blader working than start messing with a 12 blade later myself.
Right now I think it's slipping because the amps are down, not where I thought it would be for a static test (30amps on 2800kv lol).
I have pics at the end of the "balancing an EDF with a cell phone" thread. It appears that I need to modify the mounting system to somehow fully support the fan shroud. Do you still have the stock fan/motor? I would gladly by it from you.
