GEPRC Sparrow MX3 MSX3 Upgrade Kit

thingiverse

Banana Science continues to push the boundaries of mini quad innovation with its latest upgrade kit. The kit now features sleek TPU sleeves that replace bulky motor guards, saving weight while giving builds a significantly cleaner look. The new TBS Immortal T mount allows users to install an Immortal T on even the smallest 3" builds without relying on crude cable ties and electrical tape. Meanwhile, the stock Sparrow frame only accommodates a (RP)SMA connector when using a 20x20mm FC stack, leaving no room for installation near the rear. However, the new extended (RP)SMA antenna mount optimizes the TBS Unify adapter cable, enabling users to securely attach a (RP)SMA antenna on top of their frame even with bulky 30.5x30.5mm FC stacks. For those looking to build long-range 3" quads, Banana Science's easy-to-install mini GPS mount allows for seamless integration of small GPS units onto aluminium canopies. The (RP)SMA antenna mount, TBS Immortal T antenna mount, and mini GPS mount all snugly fit between the aluminium canopy when screwed together and remain securely fastened by pre-existing CNC notches in the frame. Not having a 3D printer is no barrier; the complete upgrade kit or individual parts are available for purchase on eBay. **Arm Protector Details** Designers at Banana Science have created arm protectors specifically for those who prefer mounting ESCs on their arms or lack space for a 4-in-1 setup. These shorter-length arm protectors free up more mounting room on the arms. **Antenna Mounting Details** To address ongoing debates about TBS Crossfire RX antenna mounting, Banana Science has developed methods for both 90-degree and 180-degree configurations. Through testing, mounting the crossfire RX antenna in a 180-degree configuration yields the best range but creates deadpoints at either end of the antenna. For optimal coverage at long ranges, a 90-degree mounting configuration is recommended. The Immortal T mount allows users to install an Immortal T antenna for a 180-degree setup and maximum durability and strength. Meanwhile, the (RP)SMA antenna mount enables attachment of two antenna tubes at roughly 80 degrees next to the 5.8ghz SMA connector. Note that these antenna tubes are prone to falling out unless glued with high-temperature hot glue, after which users can install a crossfire micro RX antenna in the 45-degree tubes. **Update 1** Banana Science collaborated with another FPV pilot to develop an ultimate AIO race setup mounting solution. This new mount makes it easy to mount an AXII antenna, forever tubes at 45 degrees for the RX, and protect all electronics with a protective plate to withstand even the toughest gate-bashing abuse.
