May I ask why 55c batteries in a 2m plane?
i would expect a 55c battery to be significantly heavier than a 25c for this application
Mostly I wanted to try them. and Weight was still reasonable at 1300g
Hi,
I have on my Master Mezon ESC's Acceleration 0-100% 0.50 s(sec)
I use that value on 3 Mezon's:
- In a Sebart Mythos 125E with Hacker A60-7XS and Falcon 19x12 V2 Electric carbon prop (35 grams), about 600 flights.
- In a Sebart MythoS Pro with Hacker Q80-14XS and Falcon 20.5x14.5 V2 Electric carbon prop (40 grams), about 700 flights.
- In an Oxai Galactica with with Hacker Q80-14XS and Falcon 21x14 V2 Electric carbon prop (41 grams), about 150 flights.
Never experienced any problem on rapid throttle opening.
But it is good to know that one need to watch up for this potential problem.

That is interesting to know. I did some further testing on the bench yesterday and this are my results.
I tested two types of batteries, 25C 5800mah Zippy compact and 55C 5000mah TP along with 2 different propellers, Falcon 3 Blade 19.5X13 and Falcon 2 Blade 21X13.5
With the 3 blade and Zippy compact I could get to full throttle by going slowly on the stick but if I moved the throttle quickly I received a commutation error and the motor would shut off. Increasing the acceleration to 1.5s allowed me to quickly move the stick without having the motor shut off, however this did not hold true once I changed to the TP battery and the motor would shut off.
Changing to the 2 blade prop reduced the load and allowed me to quickly accelerate the throttle with the TP battery and 1.0 sec acceleration.
One thing to notice is that the problem never presented itself until recently when summer temperatures reached 95º F.
My conclusion is that the 3 blade prop with the higher load can cause the error since the motor cannot accelerate quickly enough, slowing the acceleration time is the only solution. Ambient temperature seems to play a roll since it never happened during cooler months.
I will try to do some testing on my pletteberg Advance see what results I get.
