Frequently Asked Questions
What does this PCBA board fix?
This is the power management PCBA board for the Flysky Noble series. It is used to repair power-on failures caused by power supply issues, such as short circuits resulting from incorrect 18650 battery installation or battery damage. If your Noble transmitter fails to power on and the issue is traced to the power circuit, replacing this board is the recommended repair.
Which Noble models is this compatible with?
This PCBA board is compatible with the Flysky Noble NB4, NB4 Pro, NB4+ (NB4 Plus), and NB4 Lite. Please select the correct variant (NB4 or Noble Plus NB4+) when ordering, as the board design differs between models.
Do I need to replace the clasp when installing the NB4+ board in an NB4 or NB4 Pro?
Yes. If your transmitter is an NB4 or NB4 Pro and you are installing the NB4 Plus (NB4+) power board, you will also need to replace the clasp with the NB4 Plus version. Please ensure you have the correct clasp before proceeding with installation.
Where can I find the installation tutorial?
An installation tutorial is available in the video description of the review video linked on this product page. Please watch the video and refer to the description section below the video for step-by-step replacement instructions.

I love my FLYSKY GT5 transmitter and was so distraught when the steering potentiometer started to fail. Luckily a friend mentioned SoarSky and i ordered a replacement and am back to enjoyable RCing
