Rocket Pic“The HI-TECH H45 is a smaller version of LOC's famous EZI-65. It has a single 38mm motor mount. This hot performer has been tracked to over 3500 ft. when flown with long burn "H" class motors.”

  • Pre-slotted airframe/fin construction
  • 28" Parachute
  • Payload section

RECOMMENDED MOTORS: (from Loc)

  • F50-6 (requires 29mm motor adapter)
  • G40-7 (requires 29mm motor adapter)
  • H45-10
  • H80-10

This is a typical Loc kit; strong (for paper) airframes with a 38mm. Motor mount, strong plywood fins (3/16 in.?), and an elastic shock cord. This kit could be called a classic (there are few high power flyers that have not seen one) loc kit. Like a stretched Graduator (with larger fins perfect for long burn motors), this kit can go on an F25W-4 or an I just as well (but keep an eye on the thrust and altitude!).

Rocket Pic (Provided by Magnum Hobbies) The kit comes in the typical plastic bag but the parts seldom break. Construction is very simple (less than 15 parts) with 5 min. epoxy and 30 min. epoxy for reinforcement. The fin tabs are actually pretty long (unlike the smaller Loc kits). The nose cone is very strong (as usual) and the payload is good for some storage (or just stability for the low thrust motors).

I have made two High Tech H-45 kits, the first was my next rocket after a Graduator. Because this first H-45 kit was lost in a tree, I eventually got another High Tech. The fins can be very strong if they are coated internally with 30 min. epoxy (keep the aft centering ring out during construction, and pour the epoxy into the room between the fins).

The first rocket took to the sky on an F25W-4 for a low and slow flight. I replaced the 28” stock chute (way too big for this rocket!) with an 18” chute. Despite this change, the rocket drifted into the only tree near the pads and got tangled. (The rocket is probably still there today!)

My next kit, purchased to replace another lost rocket (I always need a light 38mm rocket on hand for some reason…), was built to be stronger (for my 38/360 RMS can) and painted with gloss black and day-glow green for visibility. The flight, my level 1 cert, was on an H238T-10 (a powerful little thing!). The flight was nice and fast with an altitude of around 1600 ft. Because this flight was at RATS (2000), I assumed that the stock 28” chute would be fine, but I nearly lost the rocket to the creek behind the field. After 30 min. of walking through 15ft. grass, I got the rocket back and received my certification.

Construction is a 4, the kit is easy to build and easy to fly (nice high performance) but it is not perfect; the paper frame and elastic shock cord are of limited strength.

I would rate the flight a 4 (out of 5) because this is just about as good as this type of rocket (paper airframe and elastic shock cord) can get, but it is by no means zipper proof. The shock cord could be replaced with Kevlar®, but I have never had a Loc recovery failure despite the elastic. I think that a strong version of this kit would be great on any 29mm or 38mm H, and the small I motors (or even the slow full I motors) would give very high altitude. I think that the I211 would not be out of the question, perhaps even the I284 with a long delay. Rockets like the High Tech H-45 are really built for slow, graceful flights so the G25W-5, H45W-10, and the mini H motors (H35, H55 etc.) are really the way to go. This is a great kit at a pretty low price that can take a wide range of motors, I recommend it as a good addition to any rocket collection. This encoded message has been converted to an attachment.

Over all, the kit is still a 4, but this is pretty good for a paper kit because it is a classic.

GUEST's OPINION:
08/03 - "I build this fine LOC kit for two special purposes. 1) To fly an on board video cam 2) To fly on Nitrous Hybrid motors as an option I build the kit according to the instructions, and added a 2.6 altimeter bay in place of the standard bulk head. The stock payload bay has plenty of room left to hold the main chute included in the kit. We used a 38/29mm adapter to fit a Ratt Works H70 hybrid motor into the rocket. A vent hole for the 1/8” tubing was added to the side as well as the two 1/6” holes specified in the kit instructions. A perfect flite minialt/WD was added to the altimeter bay and ejection charges fitted. We fitted a camera and transmitter to the nose cone of the rocket. It was flight tested at Naram 45 on a G40, the dual deploy worked fine. Also at Naram, the Ratt H70 Hybrid was fired in it for a crowd pleasing flight. The comment from behind was "That was a Hybrid ?!?! At JMRC at the MIS speedway, we decided the rocket likes drogue-less recovery better and only used the main chute. This lets the rocket come in horizontal and right back to the pad. The crowd loves to see that bright orange chute open at 300 feet from the horizontal drop. It flew on a Pro38 H153 to 3000 feet. The next motor we will use is the Pro38 I205. This well built kit will hold up just fine." (A.A.U.)

GUEST's OPINION:
09/01 - "I'm not the only one to find the fin slots poorly positioned in this kit! My addition of eight feet of 300 lb. Kevlar, a Quik-Linc, positive motor retention T-nuts and Kaplow Klips/Tripod motor retainer, 3/32" plywood fin strakes and Pratt Parachute Protector make the 28" 'chute just the right size. Could be a perfect dual deployment bird, she LOVES slow burners!" (M.F.)

GUEST's OPINION:
01/01 - "Being that it's one of the few mid-power kits that LOC makes that actually has fins that go through-the-wall and to-the-motor-mount, I would recommend this kit for anyone that wants a great rocket that will fly on anything from an F engine up to to an H. My only quibble with the kit (and most of LOCs 2.6" diameter rockets) is that the tubing is pretty whimpy compared to the other diameter tubing used in LOC kits. I wouldn't fly this bird on a high-impulse H or I motor without glassing the airframe. I would consider this kit a good alternative to the LOC Graduator as a first-time mid-power kit because of the better fin arrangement (TTW/TTMM)." (Y.L.)

(6000 ft)
10+ mph winds - Great, very high flight to 6000 ft. Rocket is stock except for altimeter deployment.
07-15-1995 March Briner AT RMS G64-7 Didn't Record 0-5 mph winds - Very nice flight.
07-15-1995 March Briner AT SU G40-7 Didn't Record 0-5 mph winds - Good flight.
07-03-1996 March Briner AT RMS H238-10 Apogee - NC Down 0-5 mph winds Event: LDRS-15
- Ron Schultz was nearby when I brought this to the RSO table at LDRS XV. He expressed some concern about using an H238. It flew great. Nice, fast lift-off. No signs of stress afterward. I LOVE H238s!
05-12-2002 March Briner AT RMS H238-7 Just Past (1-2sec) 0-5 mph winds - Certification flight. FAST boost, ejection just past apogee. Cert Flight: L1
08-31-2002 March Briner AT RMS H238-10 Didn't See 5-10 mph winds - Cloud deck turned out to be lower than I thought. Rocket went into the clouds. Ejection sounded like a cannon. Lower half of rocket apparently collided with payload section putting big dent in it. Damaged, but easily repaired.
07-02-2005 March Briner AT RMS G64-7 Apogee - Perfect 0-5 mph winds - Carried RRC2X altimeter. Forgot to arm the altimeter after changing a bad ignitor. Motor ejection deployed recovery system right at apogee.
07-01-2006 March Briner AT RMS H128-M Didn't Record
(1921 ft)
0-5 mph winds Event: SCIPower 2006
- Great flight. Actually remember to arm the altimeter this time.
07-19-2002 Nik Byra AT RMS J350-14 Didn't See
(7000 ft)
Light winds -
11-08-2008 Carl Campbell AT RMS H123-M None - Nose Cone Stuck 0-5 mph winds RIPFlight PictureEvent: Bunnell Blast
Delta-IV - Great launch with a Flash at liftoff. Post Mortum showed excessive lube prevented the delay of igniting the Black Powder ejection charge. Status: Lawn Dart
01-22-2000 Dale Emery AT SU H45-10 Didn't record
(4500 ft)
10+ mph winds - AltAcc used for altitude determination. It flew nicely, with about a 7 second burn. Recovered without a problem. The AltAcc data was not retrieved (problems with the software). Softwaresimulation predicted an altitude of about 4500 feet.
06-10-2000 Dale Emery AT RMS H123 Didn't record
(3033 ft)
5-15 mph winds - My last flight of the day was the Hi-Tech on the H123-W that didn't light in the Thunder -N- Lightning. It had an excellent flight to 3033 feet
09-15-2000 Dale Emery AT SU H45-10 Didn't record 5-10 mph winds - First flight. I love that long burn motor.
09-17-2000 Dale Emery AT SU H45-10 Didn't record 5-10 mph winds - I really like that motor
10-14-2000 Dale Emery AT RMS H112-10 Didn't record 5-8 mph winds - Another nice flight.
10-26-2000 Dale Emery AT RMS H123-10 Didn't record 5-10 mph winds - A nice flight; however, the chute tangled and did not inflate. The body tube crimped a little on landing.
03-24-2001 MikeyR AT RMS H73-10 Very Early 0-5 mph winds - Delay seemed more like a short. Major zipper in airframe. Don found the nose cone in the field (somehow!)
08-05-2004 Sean Prestia AT RMS H242-10 Didn't See 5-10 mph winds Event: METRA launch
- Great level 1 cert. Went up very fast. Cert Flight: L1
08-10-2002 Al Sterner Ces RLD G69-7 Apogee - Perfect 5-10 mph winds - Deployed right at apogee. Nice long walk to recover. No damage. The Pro 38 G load puts it up about 500' higher than the sim I ran.
04-13-2003 Al Sterner Ces RLD G69-7 Apogee - Perfect 5-10 mph winds - Nice very straight boost. About 1/2 mile walk to recover.
09-06-2003 Al Sterner Ces RLD G79-10 Just Past (1-2sec) 0-5 mph winds - Tried 10 sec delay this time. Ejection was just past apogee. Nice flight. A pretty reliable flyer.
09-??-1999 Russell Taragan AT SU F25-4 Apogee - Perfect Calm - Nice low/slow flight, 18 chute was nice but the thing still hit a tree! Never Came Down.
04-??-2000 Russell Taragan AT RMS H238-10 Apogee - Perfect 0-5 mph winds - Nice fast flight(my level 1 cert), good altitude for the small H. Almost lost the rocket in high grass(the 28stock chute is too big!) Estes Industries - AIM-9 Sidewinder Cert Flight: L1
07-28-2000 Russell Taragan AT RMS I161-10 Apogee - Perfect Calm - Very good altitude (5000?), hard to see at recovery. Quite fast at lift off. I used an 18in. chute to ensure recovery.
