01/03/1999 – Purchased Aerotec #89020 Barracuda from Joe’s Hobby Barn for $35.99 (Retail – $39.99)
03/17/2002 – Opened kit and found all part were included. Took pictures and downloaded to computer. Already scanned plans. Marked motor tube along centerline at 7/8″, 2-18/16″ and 4-5/8″. Cut 1/4″ long slits 90 degrees to center line at 4-5/8″ mark. Inserted motor retainer into slit. Slid one of the fin lok ring over the rear of motor tube and uyp to the 7/8″ mark wher the forward end of the ring meets the mark. On the forward end of the motor tube, slid the other fin lok ring to the 2-15/16″ mark with the rear of the ring touching the mark. Test fit the fit of the fins in the fin lik rings and them removed the fins. Epoxied the fing to the motor tube being careful not to get any in the slots. Cut 1/4″ long slots at 90 degrees from each other into the front of the motor tube. Then epoxied the baffle shoulder to the front of the motor tube. Ran a bead of epoxy over the slots and baffle tubing. Inserted cooling mesh before epoxying the baffle to the forward end of the motor tube. Attached a screw eye to the baffle and attached the shock cord to the screw eye. After the epoxy cured, slid the motor tube assembly into the body tube and epoxied the fins to the fin lok rings. Epoxied the centering ring to the rear of the body tube. Filleted the centering ring/body tube joints with epoxy. Epoxied the bulkhead to the tube coupler after inserting the screw eye and shock cord.
