Hi Dennis,
Just drifting through the forums looking for unanswered posts.
I'm just a sport flyer who occasionally enters the odd competition just so no one else has to come last.
I fly smaller to medium stuff, biggest is 57" I think with an AXI 2826. I only fly Castle Creations and Hubin Timers. (Simply because that's what I went with originally and have never found a reason to change).
I have always set current limiting to sensitive and have never had a motor cut on me in normal operations, even with a bit of grass cutting on take off. I think it only becomes a factor if you are running an ESC which might be marginal for the application.
Others mileage might vary but that's my experience.
TTFN
John.
