Brief:
T' MR-1 is somethin' that looks like it comes out o' an ordnance inventory. Openin' t' bag, arrr, that impression is confirmed as one looks at t' parts. Ahoy! T' Quantum tubin' and glass fins make this a heavy and substantial rocket. Avast! Arrr! T' NC makes it even more so.

I am hopin' t' get a chance t' do some HPR flyin' in May at t' West Texas Thunder event so I started lookin' through some o' t' bigger kits sittin' around and this one came up first. Mine came with a 29mm mount but it is available with a 38mm mount as well.

Construction:
My first step on readin' through t' instructions be t' take a closer look at t' Quantum tubing. Arrr! I had never worked with this stuff before. Ya scallywag! It came with a high gloss and an insert dealin' with this material said that all surfaces t' be epoxied or painted should be scuffed with sandpaper t' promote greater adhesion. Blimey! That bein' t' case, matey, I gave it a good scrubbin' which removed t' high gloss.

T' kit came with two plywood centerin' rings. Well, blow me down! Avast, me bucko, me proud beauty! Blimey! One o' them has a slot t' accommodate t' nylon harness. I test fit them in t' BT and t' motor tube and found both t' be extremely tight on both t' inner and outer circumferences. Well, blow me down! I started t' sand them down. Avast, me proud beauty! Blimey! Accordin' t' t' instructions, arrr, matey, me bucko, a bit o' tightness is desirable in t' forward rin' (the one with t' slot) but t' aft one should be loose enough t' slip off without too much trouble. Begad! Eventually, shiver me timbers, these criteria were met.

A mark was made on t' forward end o' t' motor tube and a band o' epoxy was run around t' circumference with a 1" gap for t' strap hole. Avast, me proud beauty! Blimey! Blimey! Blimey! Blimey! Blimey! T' rin' was then seated. Avast, me proud beauty! Blimey! When t' first bit o' epoxy had set, t' forward rin' was filleted, again leavin' a gap for t' strap.

T' aft rin' was then slipped on but nay epoxied. Aye aye! T' facilitate removal later, matey, t' instructions directed that I attach 3 strips o' cellophane tape t' ring.

T' kit uses a piece o' flat nylon strap for t' recovery harness. Blimey! It is supposed t' slip through t' notch o' t' forward ring. Mine would nay and me attempts t' get it t' do so resulted in a frayed mess. I used a razor cutlass t' cut off t' frayin' and form an angle at t' end o' t' strap. Aye aye! Arrr! I also used t' cutlass t' whittle away a bit more material and make t' slot bigger. Begad! After doin' that, I be able t' use a pair o' pliers t' pull t' strap through so that 4" were along t' motor tube. Ahoy! Well, ya bilge rat, blow me down! A bed o' epoxy was laid down and then t' strap was embedded in t' epoxy and held down with maskin' tape.

T' next step was t' install t' motor mount into t' airframe. Well, blow me down! T' instructions called for placin' a rin' o' epoxy 7 inches in from t' aft end. Begad! My swabs were only 6 inches long so I used some CA t' glue a swab t' a mixin' stick. Ya scallywag! T' lengthened swab was then marked at 7" and a rin' o' epoxy was applied. T' motor mount was shoved in, makin' sure that t' strap be offset from all fin slots. Begad! It be pushed in until t' end o' t' motor tube was flush with t' airframe.

Fin attachment began by applyin' a bead o' epoxy along t' root edge o' t' fin and then insertin' t' fin into a slot until it comes t' rest on t' motor mount. Once in place, ya bilge rat, alignment was checked and t' fin be taped t' hold it in position until t' epoxy set. Avast! Then t' next fin was done in t' same manner as was t' third one.

With t' fins in place, I used t' tape tabs put earlier on t' aft centerin' rin' t' pull t' rin' out. Ahoy! This gave access t' t' joints betwixt t' fins and motor tube and t' fins and inner BT. Ahoy! Avast! Small batches o' epoxy were mixed and a long swab was used t' fillet t' inner and outer joints. Aye aye! Avast! At t' same time, shiver me timbers, arrr, me bucko, t' outside o' t' BT was filleted t' t' fins. Aye aye! Avast! T' epoxy fillets were smoothed by a glove clad finger dipped in alcohol.

At this point I need t' confess up t' a blunder. Ahoy! My thought was that t' inner fillets did nay need t' be pretty and I be kind o' messy applyin' them. Well, blow me down! This led t' later problems in gettin' t' aft centerin' rin' back in place. Begad! I ground t' blobs down as best I could but t' rin' still wouldn't go in. Aye aye! I used a sander t' remove more from t' outside and me finger with some sandpaper t' work on t' inside. Ahoy! It helped but nay enough. Then I got t' bonehead idea o' forcin' it. I used a rubber headed mallet t' get it started and it did start. It was also apparent that it was never comin' out again. Arrr! Well, blow me down! I was committed. Blimey! Well, blow me down! Then I got dumber. Avast! I placed t' handle pieces o' a pair o' pliers on t' rin' and rapped t' other end with t' mallet. Begad! This drove t' rin' down but also split t' wood. It wasn't split enough t' be removed, but it was pretty awful looking. Avast, me proud beauty! Well, blow me down! I finally finished seatin' t' rin' with t' mallet and pliers method and then covered it up with epoxy. Aye aye! Well, blow me down! It's ugly but should work. Besides, shiver me timbers, ya bilge rat, people have no business lookin' up t' behind o' strange rockets.

Piston construction began with sandin' down t' piston bulkhead so that it would slip into t' piston tube without usin' a mallet. Begad! This did nay take too long with a belt sander. T' nylon strap attached t' t' motor mount was then fished through t' provided slot, matey, passed through a D ring, shiver me timbers, and then passed back through t' slot and snugged up. Epoxy was then used t' bond t' strap in place.

When t' epoxy around t' strap had dried, arrr, t' piston bulkhead was inserted into t' piston tube and epoxied into place with fillets on both sides.

T' transition section still needed t' be put together. Ahoy! Begad! Blimey! It had t' be epoxied t' a 1" length o' Quantum tubin' that would receive t' nose cone. I scuffed up t' plastic with sandpaper and t' epoxied it into place.

T' transition was slid onto t' BT down t' t' fins. Blimey! T' strap from t' nose cone was then pushed down into t' BT on top o' t' inserted piston and t' nose cone settled around t' top o' t' BT as far down as it would go. Blimey! T' transition be then moved up until it housed t' lower end o' t' cone and a line be marked on t' BT and t' transition slid back down. Well, blow me down! A rin' o' epoxy was then applied at t' line and t' transition slid back into place. Begad! Well, me hearties, blow me down! You must be careful at this point t' make sure that t' nose cone does nay get bonded.

All that was left, except for t' lug, was t' attach t' strap from t' nose cone t' t' top o' t' piston.

Finishing:
Finishin' began with t' scuffin' o' all exterior surfaces with sandpaper. Begad! I started with 220# and then went t' 400# because I didn't like some o' t' gouges.

Then it was into t' booth for t' first o' 2 coats o' Kilz. Ahoy! When it came out a few days later, t' Kilz was lightly sanded and I masked off t' part o' t' rocket from t' transition aft.

I am nay overly fond o' flat paints so I decided t' go this somethin' similar too, but nay like t' "publicity photo". Begad! I proceeded t' give t' forward section a coatin' o' flaky metallic silver. Aye aye! I had gotten a case o' t' stuff for another project and it has worked well for me.

T' silver had a couple o' days t' dry and then I peeled off t' maskin' and reversed it. Blimey! T' bottom o' t' rocket be then sprayed with a glossy, me hearties, dark green. Blimey! I don't know where I got t' can from. I didn't even know that Valspar made rattle cans.

When t' green had dried, t' maskin' be peeled off and t' results inspected. Aye aye! I was satisfied and needed only t' get t' work on t' lug.

Construction Rating: 4 out o' 5

Flight and Recovery:
T' first flight o' t' MR-1 was a comic tragedy o' errors. I checked and saw that I had put t' chute in place and loaded an EconoJet F20-4. Ya scallywag! Well, ya bilge rat, blow me down! Blimey! It came with a Copperhead igniter, shiver me timbers, o' course, but I had never had too much trouble with those...until today. Ahoy! It didn't even tickle t' motor.

I replaced t' igniter with a First Fire and got ignition, ya bilge rat, after a fashion. Begad! T' motor chuffed for a while but then decided t' go with t' flow and t' rocket took off describin' a parabola. Begad! At this point, we all knew that trouble was brewin' but I kept hopin' that, me hearties, somehow, t' chute would eject. Avast, me proud beauty! I ran around a truck that be obstructin' me view and had just enough time t' see t' following:

1. T' ejection charge fired about 10 feet off t' ground.
2. T' chute be in t' tube but had nay been tied into t' harness (It flutters nicely, by t' way)
3. T' rocket takes a core sample.

Some o' t' excitement can be seen here on video.

Things got stranger after that. Begad! Blimey! Ahoy! Blimey! T' first really strange thin' is that t' rocket had no damage. Arrr! Ahoy! That made me think it was indestructible and ready it for another flight.

This time I loaded a G38-4J. Aye aye! Ahoy! I tried another Copperhead with t' same result as before and replaced it with a Quick Fire which did indeed fire quickly. T' rocket flew well, me hearties, went up, sounded good, me hearties, shiver me timbers, t' piston deployed t' chute just t' way it was supposed t' and t' rocket came driftin' down. Aye aye! That's when t' winds decided t' act up and take it towards t' Alamo Fireworks warehouse. Ignorin' me pleas, matey, me bucko, me bucko, it landed on t' wrong side o' t' fence.

Several o' us saw it land gently. Well, blow me down! Blimey! I decided t' go on Monday t' reclaim t' rocket. Alamo has always been very good about that. Avast! Avast, me proud beauty! At t' end o' t' day though, another club member was drivin' off and noticed their gate was open. Ya scallywag! He retrieved his own rocket and me MR-1.

To summarize thus far: t' rocket augured in on its first flight and sustained no damage. Now it had landed gently t' way it is supposed t' and it popped a fin. Blimey! A video o' t' second flight can be seen here.

Flight Rating: 4 out o' 5

Summary:
I like this strange little rocket. Begad! It will be fixed and fly again.
