(by Andy Turits - 02/13/05) Semroc Triton

Brief:
This is a very basic high performance 4 fin and nose cone model that is part of the RetroRepro series by Semroc. It was designed in 1968 and was the first released Semroc kit. Here it has been updated with laser cut fins and an improved launch lug.

Construction:
The kit comes with 1 body tube, 1 balsa nose cone, 1 launch lug, 1 sheet of four laser cut fins, 1 specs decal, and instruction booklet. The fin sheet is safely tucked inside the instruction booklet.

The instructions and construction of this model are straightforward and simple. It is easy to build and the instructions provide a fin guide to make your first marks. The laser cut fins are very good quality and an appropriate thickness. The 11 construction steps are in a logical order and clear illustrations should help out a first time builder. There really are no gotchas and no special tools are needed because this kit is as basic as it gets.

Finishing:
The instructions also provide a real nice description and illustrations on finishing which will be helpful to first timers. After several sealing and sanding coats my Triton was primed and then spray painted day glow orange for tracking and recovery ease in Winter flights.

Construction Rating: 5 out of 5

Flight:
The recommended motors were A8-5 for an approximate altitude of 600', B6-6 for 1000', and C6-7 for 1600'. I didn't have any A8-5s and I had no intention of launching on anything more powerful than an A so I could complete 3 flights with recovery for purposes of this review. Featherweight Recovery required no wadding but a wrap of masking tape around the motor base was necessary to keep the motor snug in the body tube. First flight was on a 1/2A6-2. Very straight to about 300 feet. Short delay and nice sharp ejection pop while Triton was coasting upward. Motor landed about 10ft from pad and Triton planted nose first about 30ft from the pad. Next launch on an A8-3 and went to about 500ft. Due to the short delay, it ejected as Triton was still coasting upward. For the third launch I sleeved a 1/2A3-4T in a used 18mm casing. This propelled the Triton to about 200-250 feet and provided a more appropriate delay so that it was horizontal at ejection. All flights were straight up though a minor spin (less than 1 rotation) was witnessed in the lower powered flights. 5 mph gusts of wind may have been the culprit here but there wasn't any signs of windcocking in the gusts.

Recovery:
Once separated from its engine, the Triton falls really fast. Mine also had a nice spin on the way down. As the balsa nose hit the defrosting ground three times it sustained a little damage. It was nothing that can't be sealed and repainted. I also want to point out that the damage did not seem to impact subsequent flight performance. It probably would be fine nosing in to a non-frozen field or better yet some soft grass. I wouldn't want to wreck the retro feel of the Triton kit by changing out the balsa nose for a plastic one with some added weight, but it's food for thought.

Flight Rating: 4 ½ out of 5

Semroc Triton

Summary:
There really is no downside to this rocket. The packaging brings you back to the early days of the hobby. It takes about 10 minutes to build and of course longer to finish depending on how you want it to look. The retail list price is $2.50 and online vendors let em fly for significant savings. You really can't go wrong with this kit. The Triton would be an ideal first rocket or a carton of them would be great for a scout or group build. Featherweight recovery means no wadding is required so it's a great cost per flight bargain and prep time is minimal. As previously stated, a plastic nosecone could be considered for durability but I feel would detract from the retro feel of this kit.

GUEST's OPINION:
03/06 - "I half expected to lose my Triton on its first flight, so I just put in an A8-3 engine. It took off like it was shot out of a gun. It screamed off the pad and out of sight. Of course, we never found it, but for $1.95, I'm not complaining, and the Gods of Rocketry were satisfied with the sacrifice." (B.A.)

GUEST's OPINION:
02/06 - "This was my first Semroc kit and I was very please with the quality of the components and the instructions. The review was spot on, 10 minutes to build (plus 10 weeks waiting for the weather to warm up enough for painting). Make sure you use a bright colour as this little rocket disappears even on an A. My Triton has many dents in the balsa nose, but still flies straight up. Excellent, cheap, simple little rocket so long as you are happy with dropping engines and featherweight recovery." (D.B.)

03-21-2006 Clive Davis 3x Qst MMX Apogee - NC Up 5-10 mph winds - Great flight. All three motors ignited. Streamer recovery.
03-21-2006 Clive Davis 3x Qst MMX Just Before 5-10 mph winds - Only two motors ignited. Rocket still ascending upon deployment. Streamer recovery. No damage.
06-21-2006 Clive Davis 3x Qst MMX Very Early 0-5 mph winds - Hung on the rod a bit too long (I think I need a new launch rod). Still went up well, although part of the boost was expended on clearing a slightly bent launch rod. Ejection early, but streamer deployed and rocket landed without damage.

02-13-2005 Andy Turits Est SU 1/2A3-4 Apogee - Perfect 0-5 mph winds - sleeved 13mm motor in a spent 18mm casing. Nice straight lift off. little wind gusts no problem. About 250-300 ft. altitude. 4 second delay seems about right. Triton horizontal at ejection. Recovery about 40 ft. from pad. Fun little ship!
04-29-2006 Andy Turits Est SU A8-3 Apogee - Perfect Light winds - It goes up really high and comes down 100 feet from launch pad.
05-13-2006 Andy Turits Est SU A8-3 None - Tumble Calm - It went up high and straight into clouds, ejection charge fired and separated rocket from engine...Dayglo orange rocket recovered about 100 ft from pad.engine recovered also
05-28-2006 Andy Turits Est SU A8-3 Didn't See Light winds - Our little wind testor...Triton goes up...Triton comes down about 150 feet from the pad...look for the dayglo fins sticking out of the ground.
07-03-2006 Andy Turits Est SU A8-3 None - Tumble 0-5 mph winds - whoosh Triton goes up...pop...zzzzzzz THUNK....Triton comes down.
07-03-2006 Andy Turits Est SU A8-3 None - Tumble 0-5 mph winds - Screams off the pad, altitude about 600 feet tumble darts down...nose is getting a bit pock marked...the rocket's, not mine.
07-23-2006 Andy Turits Est SU A8-3 Didn't See Gusty - Good Morning rocket gods...Triton once again ascends to unseen altitude and returns with a thunk dayglo red fins sticking up about 100 feet from launch pad.
08-26-2007 Andy Turits Est SU B6-4 Didn't See Light winds - tiny triton went way up possibly 1000 feet yet was spotted coming down about 200 feet away. This thing has had a LOT of action as a wind tester...
08-09-2008 Andy Turits Qst SU B6-4 Didn't See Light winds - This little feller went straight out of sight probably to at least 1000 feet...retrieved about 500 feet from pad thanks to the dayglo red paint..(triton's) old school balsa nose is getting very chipped.
