Brief:
A reproduction o' t' very first model rocket built by Orville Carlisle in
1957. Ahoy! Aye aye! Single stage, shiver me timbers, arrr, parachute recovery. Arrr! 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. Avast, me proud beauty! Each step is illustrated with very professional quality pictures, sometimes several pictures in a single step. Well, blow me down! As an example, 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. Who else does this? Too few. Even their very complete listin' o' tools and materials needed was illustrated. This kit, as with most of their kits, could be built from t' instructions by someone who'd never seen a model rocket before. Avast! 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, so complete that they note that t' nose cone on t' original Mk II was a plastic pencil sharpener. A very few kit builders have instructions this good. T' rest should.
As noted, a complete beginner could build this. There were no hitches or problems. Begad! T' pre-cut fins were far better cut than many other LPR models. Aye aye! Well, blow me down! 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! Aye aye! Everythin' fit properly the first time. Avast, me proud beauty! As a reproduction o' t' original, built before thar were lighter weight components, t' parts are comparatively very sturdy. Avast! Aye aye! In fact, shiver me timbers, it's solid as a rock.
Finishing:
Complete finishin' instructions are included, even givin' t' paint scheme of
the original (international orange with a red nose). Avast! Blimey! A decal is included that
shows t' Semroc logo, ya bilge rat, t' name o' t' rocket, me hearties, and even t' dimensions o' the
original. Begad! Blimey! Even t' model itself becomes a learnin' experience. Well, blow me down! Blimey! I finished mine
per t' instructions, arrr, includin' t' original paint scheme. Blimey! Blimey! I'm glad I did.

Flight:
Recommended motors are A8-5, me hearties, me bucko, B6-6 and C6-7. Ahoy! Avast, me proud beauty! Estes waddin' was used. Avast! Motor
retention is by engine hook.
For t' first flight I used an A8-3 because that's what I had. Begad! I would have been better t' get t' longer delay. Well, blow me down! Ejection was before apogee, but deployment was fine. T' boost was fast and arrow straight, shiver me timbers, a perfect and beautiful maiden flight.
Second flight was on a B6-4. Begad! Again, ejection be before apogee, me hearties, but the flight be otherwise great. Avast! Ahoy! It impressed t' crowd. I too was impressed by the success o' this "old" design. Ahoy! Ahoy! So much so that I resolved t' build an upscale. Avast, me proud beauty! And so I did (the Rock-A-Chute Mk III). Blimey! Begad! Havin' done so, 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, shiver me timbers, matey, t' body is fairly
short, 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. Blimey! Keelhaul®©™® is flame resistant but nay flame proof. Arrr! I've had it burn through on me Mk III, an upscale o' this design, due t' t' close exposure t' ejection charges. Avast, me proud beauty! Motor mount anchorin' is fine, shiver me timbers, ya bilge rat, but t' Keelhaul®©™® should be protected for a bit above t' top o' t' motor tube. Begad! Avast, arrr, me proud beauty!
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), however, this is easily fixed.
Everythin' else about this kit and Semroc's work in general is a great big PRO. Begad! A beginner would benefit by startin' with a Semroc kit. Begad! A seasoned veteran will appreciate t' historical value and t' superb job on t' kit and instructions. Begad! Avast! It's a rare rocket that I want t' preserve t' just sit on a shelf and show off. Ahoy! Begad! 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 ...
