Thanks for the reply j.duncker, I truly appreciate that.
I presume I will need to cycle the batteries to begin with? I remember doing this when I first took up this hobby. I know my Ripmax has that capacity, so I will make a run of between 5-10 cycles (as recommended) to open up the batteries.
If you find a copy of the manual then that would be great. I can give you my personal email if you like to send it to.
No doubt I will have more questions before taking flight again.
Kind regards,
Richard
