Hi good day Steve,

Thanks for reaching out to us!
Sorry to hear you are struggling with your AIO. Would you be able to send us some clear photos of the top and bottom side of the board, and a short description of what you have tried and/or set up so far?

If I can’t make any recommendations, I can for ward this onto HM and ask one of their engineers to take a look at it for us.

Hope this helps.
If there is anything else I can help with please do let me know?

Regards,
David

Firstly,this is second replacement board on my tinyhawk 3plus freestyle…I fried the first when I got stuck in a tree… I connected to betaflight,no beeps but not sure if it should with no battery …everything seemed to be ok…the 3d model moved as it should…soldered on the battery lead and the motors…tried with smoke stopper…all ok…bound to transmitter…armed …only 3motors worked…re soldered another motor of same type…no change…not sure what to do next?

Many thanks for any help, steve

Ps, as you can probably see,I am still learning soldering…

Hi Steve good day,

Thank you for the photos and description, this does help us. I have emailed this through to HappyModel and asked one of their engineers to take a look for us.

I can’t see anything apparent from the images, but lets see what HM says.

As soon as I hear back I can update you.

If there is anything else I can help with please do let me know.
