Is full throttle better for the ESC then 75% or 50% throttle ?

Started this discussion. Last reply by Hans H. Jul 30. 3 Replies

I have read that an ESC is not using the same cooling internal circuit while operating at 100% or at 50 / 75%, and that therefore, the ESC cooling system will be more powerful at 100% than at 50 /…Continue

"A drone who has engines at 100% can not balance. You must have 10% - 20% to keep the balance. MOSFET + PWM ... no difference in efficiency 0% - 100%."

"Do you know whether you were reading about ESCs designed for brushed motors or brushless motors? I know of old ESCs that handled more power when operating at 100%... but that was because they would effectively just connect the DC brushed motor…"

I have read that an ESC is not using the same cooling internal circuit while operating at 100% or at 50 / 75%, and that therefore, the ESC cooling system will be more powerful at 100% than at 50 / 75%, so it advised to use the right prop to allow the ESC to run at 100%What is the logic behind this calculation, and is that correct ?I am using 3000w 100KV 12S motors and a 140A ESC.Thank you See More

Bonjour,

je souhaites une formation sur l'utilisation de base de MP et apm 2.6 ma configuration est montée sur skywalker mais je ne pense pas qu'il y a une grosse différence avec le bixler, est il possible d'avoir une idée de la formation que vous proposez (date, durée, prix).
