Blade msr advice/help needed

[Davy Crockett]

Hi folks, some help needed please

I have a blade msr that is causing me trouble!

I bought it spares/repair, tinkered a bit and managed to get it to take off but few seconds into hover it goes unresponsive and uncontrollable.

Blue light on board goes dimmer as more throttle is applied until it goes out and motors still run, then cut out.

Board sent to hh and brand new one received but it still does it

Completely stumped, any advice welcomed

Thanks for looking

sounds to me like you should look at your battery

6 fully charged batteries, behaviour still the same

Turns out its down to a faulty tail motor
