Frequently Asked Questions
Is this protector combo compatible with the NB4+ (non-Pro)?
No. This combo is specifically designed for the NB4 Pro and NB4 Pro+. The battery base protector frame has been enlarged to fit the larger battery dock of the NB4 Pro and NB4 Pro+. It is NOT compatible with the NB4+ battery base, which is smaller. Please check your transmitter model before ordering.
What is the difference between the two combo options?
The 'Top Protector + Base Protector' combo ($37.99) includes both the top screen protector frame and the battery base protector frame. The 'Only Base Protector' option ($20.00) includes the battery base protector frame only, without the top screen frame. Select the option that matches your needs from the dropdown.
What colors are available?
The protector combo is available in three anodized CNC metal colors: Blue, Purple, and Red. Select your preferred color from the variant dropdown before adding to cart.
