FrSky TW R8 receiver install into my Hangar 9 Ultra Stick

TWIN series TW R8 receiver features a new stable TW protocol that benefits from simultaneously integrating dual active 2.4G frequency bands. The TW activeactive protocol is different from the general activestandby redundancy solutions (where one receiver takes over signal control only when the other is in Failsafe mode), with the TW protocol, dual 2.4G frequency bands are active on the TW series receiver at the same time.
