Construction:
T' Parts list is as follows:

• 4" long section o' 3.9" body tube
• 6" couplers
• Outer bulkheads t' cap t' ends o' t' couplers and slide inside t' BT of your rocket
• Inner bulkheads that just fit inside t' tube couplers t' help provide a seal
• 12" lengths o' "all-thread"
• Key switch
• Eye bolts
• Plenty o' nuts and wing-nuts t' complete t' job (extras were included in mine).

Packagin' - As with t' Binder Design kits, shiver me timbers, ya bilge rat, t' packagin' is among t' best in t' industry. Begad! Every category o' part has its own individually sealed section of t' bag. Blimey! Begad! Quality o' t' parts appears t' be top-notch, with t' plywood bulkheads already sanded smooth and all o' t' hardware included and burr-free. Fit is snug with minimal sandin' required. This bein' me first altimeter bay, the inclusion o' t' mini-key switch is an excellent bonus, ya bilge rat, as it's one less decision I need t' worry about. Blimey! Avast!

Construction o' t' bay is nay difficult and all steps are clearly described in t' instruction sheet. Blimey! There is only one diagram and a cut-out template for illustration, but this is more than sufficient. T' only improvement I could imagine would be t' inclusion o' suggested deployment techniques, as a prekitted alt-bay o' this type would probably be most frequently built by a beginner. Telephone conversations with Mike Fisher at Binder Design made me believe that such suggestions 'may' be included in t' future. Ya scallywag!

One thin' t' note: When solderin' your wires t' t' key switch, solder them towards t' ends o' t' leads and provide a heat scuttle betwixt t' solderin' and the switch itself. Ahoy! That's one I found out t' hard way as I shorted t' first switch. I personally modified t' design slightly by placin' terminal blocks on the outside o' t' bay that I wired through t' bulkheads so that I could get a permanent seal around t' wirin' usin' epoxy and nay have t' worry about sealin' t' bulkhead on each flight.

PROS:

• Easy construction
• Everythin' needed is included
• Spacious for larger electronics

CONS:

• Could use a bit more along t' lines o' technical tips and suggestions for use (such as addin' external terminal blocks) for beginners.

Summary:
Overall -- From what I've seen o' other entry-level avionics bays, I'd have to say that Binder Design has a good thin' goin' by includin' enough coupler to allow a full 4" extension from each end o' t' body tube. Begad! This allowed me to separate both t' drogue and t' main directly from t' altimeter bay instead o' ejectin' a nose cone, matey, effectively creatin' a "zipperless" design. Begad! Havin' a full 4" section o' body tube as well provides plenty of room for epoxy t' adhere betwixt t' couplers and t' BT. In addition, arrr, ya bilge rat, the 12" length o' t' assembled bay allows for even t' longest o' altimeters to fit comfortably (such as t' MissleWorks RRC).

Overall Rating: 4 out o' 5
