Hubsan Official Forum

hi, anyone have any ideas where i can buy a H501"S" main board? only seeing H501"A" board for sale. i need to rebuild a friends bird.

have you tried reloading all the firmware again? I have seen something simlar and it was fixed when i re flashed everything.

judging by how many people have taken a look at this post, it shows interest in the subject.
surely someone from Hubsan could shed some light on this?

i am hearing stories of new 109 firmware being released soon? Any truth in this?
