Summary
Banana Science has once again developed and refined yet another mini quad upgrade kit. This time, you can protect your arms with simple TPU sleeves instead of bulky motor guards which not only save weight, but also make your build look significantly cleaner! Our new TBS Immortal T mount allows you to easily install a bulky immortal T on a tiny 3″ build without crude cable ties and electrical tape. Additionally, the stock Sparrow frame only allows you to mount a (RP)SMA connector if you use a 20x20mm FC stack since a 30.5×30.5mm doesn’t allow room for it to install near the rear. Now, the new extended (RP)SMA antenna mount which is optimised for the TBS Unify adapter cable allows you to securely mount a (RP)SMA antenna on top of your frame while using a bulky 30.5×30.5mm FC stack! If you’re looking to build a long range 3″, our easy to install mini GPS mount will allow you to tack on a small GPS to the top of your aluminium canopy. Both the (RP)SMA antenna mount, the TBS Immortal T antenna mount, and the mini GPS mount each simply pinch between your aluminium canopy when it is screwed together and remain securely fastened by the small CNC notches already in your frame.
Arm Protector Details
For people who like to mount ESCs on their arms or just don’t have room for a 4 in 1, we’ve designed arm protectors which are slightly shorter in length than the standard arm protectors to free up more mounting room on the arms.
Antenna Mounting Details
Since there is an ongoing debate on the proper mounting of the TBS Crossfire RX antenna, we’ve designed antenna mounting methods for both 90 degree and 180 degree configurations. Through our limited testing, mounting your crossfire RX antenna in a 180 degree configuration gives the best range overall range though creates two deadpoints at either end of the antenna. For best overall coverage at long ranges, a 90 degree mounting configuration is best. The Immortal T mount allows you to mount a standard Immortal T antenna at the rear of your quad for a 180 degree configuration and the most durability and strength. The (RP)SMA antenna mount allows you to attach two antenna tubes at roughly 80 degrees next to your 5.8ghz SMA connector. Note that these antenna tubes are prone to falling out unless glued with high temp hot glue. You can then install a crossfire micro RX antenna in the 45 degree tubes.

Notes:
All parts were printed with 100% infill with 3 shells for maximum strength. If you’re trying to cut weight though, you can print the Immortal T mount and the GPS mount with 20% infill and 2 shells without sacrificing much strength. All parts were printed in Foxsmart TPU besides the soft mount pads which were printed in ultra flexible Ninjaflex TPU.
