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. T' Quantum tubin' and glass fins make this a heavy and substantial rocket. Well, blow me down! Aye aye! 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. Arrr! 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 was t' take a closer look at t' Quantum tubing. I had never worked with this stuff before. Well, me bucko, blow me down! 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, ya bilge rat, I gave it a good scrubbin' which removed t' high gloss.

T' kit came with two plywood centerin' rings. One o' them has a slot t' accommodate t' nylon harness. Avast, me proud beauty! 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. Blimey! I started t' sand them down. Aye aye! Accordin' t' t' instructions, matey, arrr, 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 be run around t' circumference with a 1" gap for t' strap hole. Aye aye! T' rin' was then seated. Begad! Avast, me proud beauty! 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. Arrr! T' facilitate removal later, 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. Well, blow me down! Arrr! Blimey! It is supposed t' slip through t' notch o' t' forward ring. Aye aye! Blimey! Blimey! Mine would nay and me attempts t' get it t' do so resulted in a frayed mess. Begad! Avast, me proud beauty! Blimey! I used a razor knife t' cut off t' frayin' and form an angle at t' end o' t' strap. Begad! I also used t' knife t' whittle away a bit more material and make t' slot bigger. Arrr! Arrr! Blimey! After doin' that, arrr, I was able t' use a pair o' pliers t' pull t' strap through so that 4" were along t' motor tube. Begad! 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. Ahoy! Avast! T' instructions called for placin' a rin' o' epoxy 7 inches in from t' aft end. Aye aye! Avast! 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 be then marked at 7" and a rin' o' epoxy was applied. Arrr! Well, blow me down! T' motor mount was shoved in, me bucko, ya bilge rat, makin' sure that t' strap be offset from all fin slots. Arrr! It was pushed in until t' end o' t' motor tube be 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, alignment was checked and t' fin be taped t' hold it in position until t' epoxy set. Ya scallywag! Avast, me proud beauty! Then t' next fin was done in t' same manner as be 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. Avast! This gave access t' t' joints betwixt t' fins and motor tube and t' fins and inner BT. Small batches o' epoxy were mixed and a long swab be used t' fillet t' inner and outer joints. Arrr! At t' same time, t' outside o' t' BT was filleted t' t' fins. 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. Avast, me proud beauty! My thought be that t' inner fillets did nay need t' be pretty and I was kind o' messy applyin' them. Begad! This led t' later problems in gettin' t' aft centerin' rin' back in place. I ground t' blobs down as best I could but t' rin' still wouldn't go in. Well, blow me down! 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. Ya scallywag! Then I got t' bonehead idea o' forcin' it. Begad! Aye aye! I used a rubber headed mallet t' get it started and it did start. Well, blow me down! It was also apparent that it was never comin' out again. Well, blow me down! Blimey! I was committed. Then I got dumber. Ya scallywag! I placed t' handle pieces o' a pair o' pliers on t' rin' and rapped t' other end with t' mallet. Ahoy! Ahoy! This drove t' rin' down but also split t' wood. Begad! It wasn't split enough t' be removed, shiver me timbers, but it was pretty awful looking. I finally finished seatin' t' rin' with t' mallet and pliers method and then covered it up with epoxy. Begad! It's ugly but should work. Aye aye! Begad! Besides, 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. Ya scallywag! Blimey! This did nay take too long with a belt sander. Aye aye! Blimey! T' nylon strap attached t' t' motor mount be then fished through t' provided slot, arrr, passed through a D ring, and then passed back through t' slot and snugged up. Epoxy be then used t' bond t' strap in place.

When t' epoxy around t' strap had dried, me bucko, 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. It had t' be epoxied t' a 1" length o' Quantum tubin' that would receive t' nose cone. Arrr! Blimey! I scuffed up t' plastic with sandpaper and t' epoxied it into place.

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

All that be left, ya bilge rat, me bucko, except for t' lug, me bucko, 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. Well, blow me down! 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. 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, me hearties, but nay like t' "publicity photo". I proceeded t' give t' forward section a coatin' o' flaky metallic silver. 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. Avast! Blimey! T' bottom o' t' rocket was then sprayed with a glossy, dark green. Begad! I don't know where I got t' can from. Begad! Aye aye! I didn't even know that Valspar made rattle cans.

When t' green had dried, t' maskin' be peeled off and t' results inspected. Begad! Begad! 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. Well, blow me down! Blimey! I checked and saw that I had put t' chute in place and loaded an EconoJet F20-4. Ahoy! Well, blow me down! Blimey! It came with a Copperhead igniter, me bucko, o' course, shiver me timbers, matey, but I had never had too much trouble with those...until today. Ya scallywag! Blimey! It didn't even tickle t' motor.

I replaced t' igniter with a First Fire and got ignition, after a fashion. Well, blow me down! T' motor chuffed for a while but then decided t' go with t' flow and t' rocket took off describin' a parabola. Blimey! Well, blow me down! At this point, we all knew that trouble was brewin' but I kept hopin' that, arrr, shiver me timbers, somehow, arrr, t' chute would eject. Blimey! I ran around a truck that was 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 was 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. Avast, me proud beauty! Blimey! T' first really strange thin' is that t' rocket had no damage. Begad! Blimey! Begad! Blimey! That made me think it was indestructible and ready it for another flight.

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

Several o' us saw it land gently. I decided t' go on Monday t' reclaim t' rocket. Begad! Alamo has always been very good about that. Arrr! Aye aye! At t' end o' t' day though, another club member was drivin' off and noticed their gate be open. Ahoy! 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. A video o' t' second flight can be seen here.

Flight Rating: 4 out o' 5

Summary:
I like this strange little rocket. Aye aye! Ya scallywag! It will be fixed and fly again.
