Not doubting your data at all mate, if I had a serious electrical question you'd be the first person I'd ask!
I just find it amazing that such a tiny plane can, if given the opportunity, draw 50 odd amps.
I am also getting my head around the esc restricting current draw in the way you describe. Would have thought the speedy would cark it before the motor.
Interesting stuff.

I Guess the Stock Esc is very Resilient with Heat Sinks on ether side, It seems to handle the short bursts.
Though i tended to fly full throttle most the time.
I am Going to order me another Rare bear, as that way i have a stock version, and the current one i will mod out with new motor.
When i get my new rare bear I going to bench test the stock Rare bear setup as well as Temporary swapping out the speedy with a 60 amp unit to bench test quickly thus not to burn out motor the amp draw to confirm the figures that i Posted.
Unless someone wants to do bench test there rare bear to concur the results.
(Just replace existing ESC to a 60 amp and give it a whirl for a Second on full throttle and see what the Watt meter comes up with)
What Do You Mean Theres a Throttle Curve ?, Its Either all the way up or all the way down
