I needed a 3" electronics bay for a special project, without hesitating I chose LOC's kit. Having experience with 4" bays from the Fantom EXL and YANK IRIS I knew the 3" kit would be good in form, function, and flexibility. The kits are complete with the exception of the electronics and hardware to mount them.
It would be nice if there was enough room between the threaded rod and the sled to add nuts to capture one end of the sled. As it is designed the sled is a pain in the neck to assemble, especially if there are ejection charge canisters on both ends. That's the only reason for 4 stars. Someone needs to get innovative and design an Av bay that is easier to use with ejection charges.
Worked well for a 75mm heavy duty cardboard conversion to dual deploy. Reasonably light and not too costly. Benefit: you can use Tite-Bond II to put it together.
Rugged design should hold up well for many high power flights. I purchased this ebay for use on a Madcow 3″ Aerobee. I am happy to say the ebay fits well.
