flashing

Hey i currently own a set of these: https://smile.amazon.com/gp/product/...?ie=UTF8&psc=1 and was wondering which revision/version of the latest BLHeli firmware i can flash onto them. As they are a generic ESC, i would like to know what firmware is compatible with them. Thank you in advance!

I just bought a Syma X8G. Having trouble binding the quad to the transmitter. When I turn on the quad, it just keeps flashing fast LED flashes and won't go to the slower LeD flashes for me to start binding. Don't know what to do. I need it to be fixed now since I have to use it in about 4 hours :(

Hi, I recently bought a Syma X8W and I am trying to fly for the first time however it seems like one of the motor is running slower then others and Remote Control is showing the signal keep flashing. Can you please help and do you know why the signal keep flashing? I have already full charged...
