Yes satyagupta, That's possibly what I meant when I said they couldn't be flashed with SimonK firmware. However I did explain that they can be flashed with BLHeli instead. Rather a different procedure needing somewhat more expensive equipment to carry it out.

The Plush range of ESCs are very good in their own right and will power any multicopter quite well. I have two which fly very well using standard ESCs and the KK2.1 flight controller. I do however prefer ESCs flashed with SimonK. I must also add that buying and using the Afro ESCs it is advisable to reflash them with the latest firmware. Even SimonK needs updating.

Anybody wishing to flash any ESCs a database has been put together with all ESCs flashable by using either SimonK or BLheli. Either Google "RapidESC Database or follow this link.

The best of luck to those with the courage to do it yourself.
