what am I doing wrong?
Your ESC has a Silabs chip so will likely need to use an Arduino in C2 mode for the initial flash.

If you download and read the manual that comes with BLHeli suite called 'BLHELI programming adapters' it explains more.

Here is a video of the process for initial flashing with an Arduino then later flashing via the bootloader.

Bit of help needed if you can.

i managed to get 6 Plush ESC's 40amp which have been flashed with BLheli stuff.

They all work fine, BUT my issue is the spool up time for the motor from 0%-100% takes 5 seconds.

I got a Silabs USB Toolstick with them as well.

What software etc do I need to sort this all out please. No idea myself.

Check your wiring and make sure you have the correct programmer selected in blhelisuite

Okay, got it working, Changed spool up time from 9 to 0 and seems okay now.

Is there anything else I should change within this program, or know about on this?

I guess it doesnt know my motor (hobbykink Radjet 800 with supplied motor)


Many thanks

Just flashed by flyfun opto 40A (AKA turnigy Plush opto 40A) and getting some strange behavior in all but one of my motors. using latest arducopter and oneshot (oneshot 125 doesn't seem to work) 7/8 of the motors don't respond to throttle and sound very off like all the timings are wrong. They only work properly when pwm frequency is set to low. The 8th esc works fine and brakes in damped light. What could be affecting the ability to receive high freq pwm signals?
Here's a vid of the problem motors
ESC not working with damped light on using oneshot (0 min 50 sec)


And details of the supported esc blheli page for my esc's
The ESC supports 2S to 6S operation. It supports damped light mode. Switching speed is quite fast. Fet resistances are around 1.3mohm for low side and high side (typ at 10V). Both low and high side fets are Nfets. This ESC uses the same code as the Plush 40A ESC.
