LOC Delta Strike FighterBrief:
A light small 29mm rocket with a stealth like appearance. A true departure from the traditional Loc kits.

Construction:
Single body tube design, with 2 large wood fins and 4 smaller stabilizing fins on the outer ends.

This was my first Loc Precision kit, so I was not sure what to expect in terms of quality. After opening the package and examining the contents, I was very satisfied. The tubes were smooth and stiff, with no dents. The fins were straight with no warping.

LOC Delta Strike FighterThe instructions were very comprehensive considering this was the beta test kit. I decided to make my own fin alignment lines on the body tube instead of using the fin alignment template supplied with the kit. I was a little skeptical about the paper wound launch lug. It seemed a little tight and bulky, but I went with it anyway. It turned out to work just fine. The shroud that went over the launch lug is made by splitting a length of supplied body tube.

I assembled all the fin components using Aeropoxy and added fillets to make the joints stronger as I intended to push this kit to the extreme to see how it handled.

LOC Delta Strike FighterFinishing:
After filling in the grooves and sanding the entire surface, the rocket was ready for painting. I used 2 coats of flat black Krylon to stay with the stealth look. I intended to put decals on before the first flight but I ran out of time and wanted to fly.

With all the fins and cutting the shroud I would not recommend this as a beginners kit.

Construction Rating: 5 out of 5

Flight:
I wanted a good engine for the first flight and the largest one recommended in the instructions (a G38-7) sounded a little too slow for the way I built the rocket. A short conversation with Larry at Rocketmotion and I decided to go with an Aerotech G80-10. So I friction fit the motor in the adapter and fit the adapter in the body tube. I then put about ¼ cup of the recovery material that came with the kit (Affectionately known as dog barf) and was off to the pad.

At launch it took off fast, straight and suprisingly quiet. At an estimated apogee of 2400 Ft. the rocket arched over and the parachute ejected (couldn't ask for a better delay). It landed about 100 ft. from the launch pad.

Recovery:
The only damage after recovery was a scorched parachute from not enough wadding. The elastic shock cord held up fine. I wish I had more time to launch it with a bigger motor, but it was near the end of the day. I don't particularly care for the recovery wadding that comes with the kit. I intend to add a Kevlar flame shield.

Flight Rating: 4 out of 5

Summary:
Overall this is an excellent kit, this will be one of the favorites in my fleet. It is robust enough to take larger motors, yet at a built weight of about 13oz. It is light enough to fly lower powered motors and still have plenty of fun.

Overall Rating: 5 out of 5

Brief:
Loc/Presicion Starfighter is an aggressive looking mid power rocket that resembles a jet airplane.

Modifications:
I used an 18 inch custom parachute from Recovery Technology. There really wasn't anything wrong with the original, I just liked the Recovery Technology chute. The original would most likely do just as well. I used a clip for motor retention and replaced the shock cord with 12 feet of 600 lb Kevlar.

Construction:
The rocket consists of:

  • one single tube
  • two wings and a tail
  • the two wings have four stabilizers

This kit is an easy build for anyone familiar with plywood fins. The hardest part is aligning the wings/tail properly and cutting the the bottom launch lug cover lengthwise. The instructions are fairly easy to understand and were usable, but for my 46 year old eyes, they could have been printed a wee bit larger. This bird is solid as a rock once the epoxy cures.

Finishing:
No special requirements or techniques, no decals are included, and paint is same as any other project of this type.

Construction Rating: 5 out of 5

Flight:
I wasn't comfortable using an E motor in a small bird of this weight, so I went straight to the F20 motors. It does require wadding (in my case "barf" cause that's what I had at the moment). Motor retention is a friction fit straight out of the box, however I included a motor clip just to be safe. It flies spectacularly on an F20 motor--boost is straight up and out of sight.

Recovery:
The Starfighter recovers fairly close due the smallish chute. I replaced the shock cord with 12 feet of 600 lb Kevlar, through the upper motor mount adaptor and wrapped it around the motor mount, epoxying it there after knotting it. The chute does have a small amount of burning on one side now after 5 flights (all on F20s) but that was my fault as I didn't add enough barf on its first flight.

Flight Rating: 5 out of 5

Summary:
I didn't find any cons although I thought the shock cord attachment according to the instructions wasn't enough, but I prefer to overbuild everything.

Overall Rating: 5 out of 5

Wind Notes
12-15-2005 Pat Corless AT SU G80-10 Just Past (1-2sec) 0-5 mph winds Event: ROC monthly launch
- 8 flights using this motor and no problems. Smooth lift-off and straight up.
11-09-2008 Andrew Grippo RoadR SU G80-10 Just Past (1-2sec) 5-10 mph winds Event: Winnsboro, La
- Very cool flight. Delay seemed long but it allowed the rocket to glide and when charge did deploy chute there wasn't any damage. Nice motor and delay combination.
06-17-2006 Aaron Head AT RMS F12-3 Just Before 5-10 mph winds Event: CIRFF-XII
- Reload is labeled as 3 seconds, was more like 1.5 seconds. Even with short delay, rocket held up and recovered about 200 feet away from the pad.
06-19-2010 Jeff Lane AT EconoJet F20-7 Apogee - Perfect
(1125 ft)
Calm Flight Picture - Good motor for this kit. Quick off the pad, perfectly straight flight. Altimeter One from Apogee is excellent for this kit because there's no payload bay. Shroud lines got singed, chute didn't open, but no damage at all.
08-05-2003 Andy Miller AT EconoJet F20-4 Just Past (1-2sec) 5-10 mph winds blackbird - Nice steaight boost, out of site.This time however the wind shifted, and it came down several 100 feet away.
08-05-2003 Andy Miller AT EconoJet F20-4 Just Past (1-2sec) 5-10 mph winds blackbird - Notes; nice straight boost, thn arced out of site into the wind.Landed within 100 feet of the pad.
08-05-2003 Andy Miller AT EconoJet F20-4 Just Past (1-2sec) 5-10 mph winds blackbird - this bird is spposed to fly on E30-4 motors, and as large as G38-7 motors, but I kept it too F20-4 motors.Same as first flight for flight straight up, and out of site.Back to within 50 feet of the pad this time.
03-20-2010 Mark Rose AT RMS F52-8 Apogee - Perfect 5-10 mph winds - Perfect first flight motor--apogee right on time. Straight up with a slow roll to the right, almost like low rate spin stabilization.
09-18-2010 Mark Rose AT RMS F52-8 Apogee - NC Down 0-5 mph winds Flight Picture - Weathercocked a bit, resulting in a slightly late ejection. No damage. Tends to 'glide' a bit over the top, meaning more forgiving of late ejections.
