Introduction
Manufacturer:LOC/Precision
Diameter:1.6000 inches
Length:42.0000 inches
Style:Scale

ALL LOC Precision kits include laser cut fins, rings, and slotted air-frames and polypropylene nosecones.

Our Park Flyer series of kits are a low-cost, durable and all-inclusive line. Made for the small field, they're super strong and can be brought down quickly minimizing drift on recovery. At 42" tall and weighing in at 14oz dry weight, the BBX comes with a 17" booster section, 17" payload, 29mm motor mount, 18" rip-stop nylon parachute, kevlar shock cord mount and fire resistant blanket! They can easily fly on E-H impulse. 



Components

2 x 17" Loc 1.6" body tubes, one with fin slots

1.6" coupler

Plywood 1.6 bulkhead

29mm motor mount

1.6 nose cone

8 Plywood fins

18" parachute

Elastic shock cord

Eye bolt

Eye screw

Construction

I started with the motor mount. First, I screwed the eye screw into the forward centering ring. I like to add epoxy to both sides of the eye screw to anchor it to the centering ring. I used epoxy to attach the 2 plywood centering rings to the 29mm motor tube. Make sure the centering rings do not block the fin slots. When this dried, I applied epoxy to the other side of the centering rings. I attached the shock cord to the screw eye, and I then glued the motor mount into the slotted body tube. Next, I epoxed the fins into the slots. While that dried, I epoxied the bulkhead into one end of the coupler. For the record, I used Total Boat Flexepox.


I then glued the coupler into the top body tube. I then used the FlexEpox with micro balloons to add fillets to the bottom fins. I then epoxied the small forward fins onto the lower end of the top body tube. I attached the shock cord to the nose cone and then attached the parachute to a loop in the shock cord. I then used JB Weld to attach an Estes 29mm retainer to the motor tube. The final step was to add rail buttons. I didn't worry about a retaining nut and just drilled a hole for a screw and after putting epoxy in the hole I epoxied the rail buttons to the body tube.


I ordered body wraps from Stickershock23.com. This made finishing the rocket a snap. Paint the nose cone white, the bottom fin can black and the mid-rocket small fins gold. Add the body wraps above and below the gold band and you are ready to fly. The final build and painted weight was 13.5 ounces. Loc publishes the weight at 14 ounces, so pretty close.

Flight

I've flown the BBX once using an Aerotech E30-7. Open Rocket predicted an altitude of 701 feet and an ideal delay of 5.7 seconds. The flight was perfectly straight, and the 7-second delay was right on the money. The recovery walk was only a couple of hundred feet. I'm looking forward to trying an F on the next flight. I'll use a Jolly Logic chute release too if I can fit it into the 1.6" body tube.

Summary

This is my third Loc Park Flyer, and they are excellent mid-power rockets. The BBX would take a bit of work to mask and paint without the Stickershock body wraps. Otherwise, this is an easy build and would be a good introduction to mid-power rocketry.
