I have a little problem. Well some problems…
Before I had a YEP heli ESC and i will use it for comparison.
Here are all details of my current build and problems
After i charged my batteries (25,2V) i (60kg) drove about 7.1 km on a flat terrain and had 22,8V left. At the begining i could drive about 30km/h and maybe faster (did not have throttle on full).
After 3-4km I just could drive about 20km/h…
When I accelerate fully in the start of my ride i get a drop out. When i accelerate slowly i dont get it.
Later when i am stucked at 20km/h i can accelerate fully and do not get a drop out…
At the half of my ride i did a little brake (2-3 minutes) and after that i could go fast for a minute but then i get stucked at 20km/h again.
The brake is not strong at all… It brakes slowly and gently but in my oppinion to weak. Also i do not have any torque. It just accelerate slowly…
With my heli ESC I had more torque and stronger breaking behaviour!
My VESC lays on foam so i tested the heating.
I tested it several times and the VESC was always warm but it was not Hot. So i dont think it is overheating.
In a nutshell:
(1) The speed shouldnt decrease after the half of a ride unless the cutoff is reached.
(2) The brake and even the torque should be much much higher.
(3) I should be able to drive twice as long.
(4) If i accelerate only in the beginning of a ride fully i shouldnt get a drop out?
I appreciate any help. Just tell me what and how to check and i will do it.
