The Jumper T20 is a popular remote control, but it lacks an official external tuner extension mount. Currently, most users utilize the Tpro Nano mount, but this accessory suffers from a series of problems, including broken screws, worn clips, loose fasteners, and an unsightly appearance. (Yes, I've encountered all of these myself…)
Therefore, I designed a Nano mount specifically for the T20, hoping to provide convenience for users and help the T20 become a legendary controller. (Jumper, can you please pay more attention to your accessories…?)
Modified from a full-size Nano adapter, the side panels and bottom circuit board compartment are retained for better protection of the clips and tuner. The front replicates the new logo on the T20's modification panel, showcasing a stylish look.
The clips are precisely designed and very strong, firmly holding the tuner in place even with vigorous shaking. Printed
using JLCPCB photopolymer 3D printing, the details are accurate. Made with Black resin, it is heat-resistant up to 56 degrees Celsius, allowing for safe use with the built-in tuner, and is light and moisture resistant, making it suitable for outdoor environments. The heatsink design is unified across

the
side and back of the T20, achieving a visually consistent look. This conceals the previously unsightly wiring channels and exposed cables, resulting in a more aesthetically pleasing appearance.


The side view
abandons the central three-hole design, opting instead for a four-hole mounting system for greater sturdiness. It's compatible not only with the original T20 but also with the Gemini version with a fan, and the future V2 fan version of the T20. (It's future-proof!) See
