Thanks for the comments Jan!
I'm still waiting for the 120A (relabeled as Turnigy) Seaking ESC. Should be here by the weekend. I need to lower the leg 1 mm. I raised it up too much the last time. Lot's o' trimming/tuning till it's set up correctly. I'm also thinking of switching to a different motor. I'm looking for a suitable outrunner to experiment with.
