Time to break out the nasty stuff.... In April 2011, Dr. Franklin Kosdon passed away. Dr. Kosdon was the originator (with his college friend Ron) of composite rocket propellant during his time at MIT and Princeton. This used hardware is of exceptional quality (far higher quality than the many Kosdon 'copies' out there.....) and includes a motor casing made from 6061-T6 aluminum, forward bulkhead beautifully machined from 6061-T6 (all aluminum items are nicely anodized in Frank's trademark Gold color), Machined graphite re-useable nozzle, O-rings for the nozzle and forward bulkhead, three snap rings (one each to retain the forward bulkhead and nozzle, one extra), nozzle washer (goes between the nozzle and snap ring), This set includes the forward bulkhead with delay well. Shipping in the Continental U.S. is 25.00 for this set. Payment through paypal only. This 1116ns hardware is a landmark motor, a direct scale-down from Frank's infamous O-10,000. It is now 'certified' as a J975 with a fast load, but I always remember it as the J1500, because we flew a higher ISP propellant in it just for fun....This motor was known for rapid disassembly of any airframe it flew in, until it flew in my ShadowAero RAVEN airframes! It is 29.1" long, and for sale for $75.00 plus shipping
