This is a 29/240 motor with a home made fin can. The motor is used as the coupler for the rocket. It can take motors from the 29mm 120 up to the Ratt I 80. The nose cone is fiberglass and made from a mold pulled from a plastic nose cone.

The launch equipment was made from an old CO2 bottle converted to Nitrous. The control box is an old first aide kit. The relays for the solenoids and the launch are from junk cars..head light relays 22 amp and a Ford starter relay 300 amp for the launch relay. The capasitors and resistors open the Solenoid valves at full amperage and then reduce the amps just enought to hold them open. This prevents the solenoids from burning out. The system is set-up with 100' cable and can easily be lengthened. The hand held firing thingy can charge the motor or dump the nitrous from the motor and has Arm and Fire anlong with a key switch The cart was made to hold all of the stuff and to be wheeled out to the launch pad.

AJ's Estes Fat Boy
This Fat Boy is/was an actual Estes kit. It has been heavily modified to take the 38/600 motor. The parts that were used from the kit are the nose cone, body tube and the decals. The body tube had the glasine layer peeled off and 3 layers of 6 oz glass applied. The bottom of the nose cone was cut off, to allow the motor to extend up into the nose cone..an anochor point was glassed in and also the inside of the shoulder was glassed. The out side of the nose cone recieved 2 layers of 6 oz cloth. The CR's are 3/16" 5 ply. The 38mm motor mount had the glasine layer removed and extends about 2 inches past the top of body, this makes it a zipper proof design. The shock cord attachment is to the very top of the motor tube and is held on with Kevelar and epoxy.. The fins are .093 G-10 and are TTW construction and glassed to the MT. 2 part foam was also used in the fin can. Rail Guides are screwed into blind nuts. A home made 12" chute was made and is folded and slid between the MT and the BT. A small amount of wadding is used between the top of the motor and the top of the nose cone.
The rocket has flown 6 times now with this set up..3 flights on I284 and 3 flights on the I435. The hardest part of flying this, is the recovery..no dah..getting it back has always been "fun". AJ has retired this rocket several times now, but always seems willing to fly it when asked to!

It only took AJ 6 flights before I finally got a good photo of his Fat Boy. Belive me this is a good shot compared to the other ones. This flight was the latest one on an I435 this past summer. It looks to be about 12 feet into the flight and RocSim says it is doing about 120 mph on it's way to almost 900mph
