The 75mm Compact Tracker Bay supplies a secure mounting for an EggFinderMini tracker and a Turnigy 2S 850mAh 25-50C LiPo in a nosecone. The 75mm EggFinderMini Compact Tracker Bay is designed to install on a bulkhead using two 4-40 machine screws in nosecone bays 75mm and larger in diameter. The bay height is 2.75 inches and with an installed EggFinderMini tracker with a stubby antenna the total height is still only 3.5 inches. The bay has a central 3/8" clearance hole for a threaded rod to go through for attaching the bullhead to a nosecone.
The 98mm Plug-In Bay is designed to install into a Wildman 98mm Nosecone coupler that has two 1/4-20 threaded rods running down from a pre-installed bulkhead at the top of the coupler. Once installed, a metal bottom stepped bulkhead is added and fastened down using 1/4-20 hardware.
