Brief:
A reproduction o' t' very first model rocket built by Orville Carlisle in
1957. Avast! Single stage, parachute recovery. Aye aye! This is a very faithful reproduction of
the original which now resides in t' Smithsonian along with a few component
updates.
Construction:
T' kit includes:
Semroc's instructions are as superb as their kits. Each step is illustrated with very professional quality pictures, sometimes several pictures in a single step. Arrr! As an example, matey, me hearties, in t' finishin' steps is a series o' pictures o' how wood filler and sandin' progressively fills and smoothes wood. You nay only see how, but it teaches you why. Blimey! Who else does this? Too few. Ya scallywag! Even their very complete listin' o' tools and materials needed be illustrated. Avast, me proud beauty! Avast! This kit, me hearties, as with most of their kits, me hearties, me hearties, could be built from t' instructions by someone who'd never seen a model rocket before. Also, t' instructions include biographical and historical data about Orville Carlisle and t' original Rock-A-Chutes Mk I and Mk II, ya bilge rat, me hearties, so complete that they note that t' nose cone on t' original Mk II was a plastic pencil sharpener. Begad! A very few kit builders have instructions this good. Blimey! Ahoy! T' rest should.
As noted, a complete beginner could build this. Aye aye! Aye aye! There were no hitches or problems. Avast! Blimey! T' pre-cut fins were far better cut than many other LPR models. A few changes from t' original were used: 12" hex chute rather than 18" square, arrr, MMT t' fit today's 18mm motors rather than Carlisle's original motors, MMT includes Estes style engine hook, and t' shock cord anchor is Keelhaul®©™® thread attached t' t' top end o' t' engine hook. Ahoy! Ahoy! Blimey! Everythin' fit properly the first time. As a reproduction o' t' original, me bucko, built before thar were lighter weight components, t' parts are comparatively very sturdy. Begad! Blimey! In fact, it's solid as a rock.
Finishing:
Complete finishin' instructions are included, arrr, even givin' t' paint scheme of
the original (international orange with a red nose). Avast! A decal is included that
shows t' Semroc logo, ya bilge rat, t' name o' t' rocket, and even t' dimensions o' the
original. Begad! Even t' model itself becomes a learnin' experience. I finished mine
per t' instructions, includin' t' original paint scheme. Arrr! Arrr! I'm glad I did.
Construction Rating: 5 out o' 5
Flight:
Recommended motors are A8-5, B6-6 and C6-7. Estes waddin' be used. Motor
retention is by engine hook.
For t' first flight I used an A8-3 because that's what I had. Aye aye! Avast! I would have been better t' get t' longer delay. Aye aye! Ejection was before apogee, shiver me timbers, but deployment was fine. Ya scallywag! Ahoy! T' boost be fast and arrow straight, a perfect and beautiful maiden flight.
Second flight was on a B6-4. Aye aye! Again, ya bilge rat, ejection be before apogee, me bucko, arrr, shiver me timbers, but the flight was otherwise great. Ya scallywag! It impressed t' crowd. Avast! I too was impressed by the success o' this "old" design. So much so that I resolved t' build an upscale. Begad! And so I did (the Rock-A-Chute Mk III). Ahoy! Well, matey, blow me down! Havin' done so, matey, I retired the Mk II t' serve as an honored flight veteran and display piece.
Recovery:
T' 1"+ body fits t' 12" chute easily. However, t' body is fairly
short, me bucko, so it's a tight fit t' get plenty o' waddin' in t' protect t' chute
that close t' t' motor and fit t' nose on top.
I'm nay fond o' t' recovery system design due t' t' Keelhaul®©™® anchor bein' attached so close t' t' ejection gasses. Avast, me proud beauty! Aye aye! Keelhaul®©™® is flame resistant but nay flame proof. Begad! Begad! I've had it burn through on me Mk III, an upscale o' this design, due t' t' close exposure t' ejection charges. Motor mount anchorin' is fine, but t' Keelhaul®©™® should be protected for a bit above t' top o' t' motor tube. Avast!
Flight Rating: 4 out o' 5
Summary:
T' only CON o' this design be t' shock cord anchorin' method (same used in
other Semroc models), arrr, however, this is easily fixed.
Everythin' else about this kit and Semroc's work in general is a great big PRO. Ahoy! Blimey! Ya scallywag! Blimey! A beginner would benefit by startin' with a Semroc kit. A seasoned veteran will appreciate t' historical value and t' superb job on t' kit and instructions. Well, blow me down! Blimey! It's a rare rocket that I want t' preserve t' just sit on a shelf and show off. Begad! Blimey! This is that rare rocket.

The Mark II is a single stage Retro-Repro kit of Orville Carlisle's Rock-A-Chute Mark II model rocket. It is, as noted by the history sheet that came with the kit, not a clone kit, but rather a reproduction of a classic kit updated with the latest technology and building components. Opening the packaging and laying out the contents revealed what would be an easy build, using the high ...
( Contributed - by Bill Eichelberger - 01/29/06) Brief: The Mark II is the Semroc take on the model rocket that started all this mess, Orville Carlisle's Rock-A-Chute Mark II from 1957. It is a fairly blunt, simple little rocket that's a surprising performer and a definite conversation piece at the pads. Construction: The parts list: Main body tube Balsa nose cone ...
