Brief:
T' Madcow HOJO M50 mid-power rocket kit is a fun kit t' build and fly. Avast! Blimey! T' kit comes with precise laser cut parts
and all o' t' extras. Begad! Blimey! If you were talkin' about a car, arrr, you would say it is loaded. Avast, me proud beauty! Madcow kits tend t' be priced on
the higher end but well worth it!
Construction:
Parts list:
I purchased two kits from Madcow, me hearties, and they arrived well packed and in excellent shape. Blimey! Inside t' heavy plastic bag, t' balsa nose cone and boat tail were wrapped in heavy corrugated paper with separate bags for t' smaller parts.
T' straightforward instructions are printed on five sheets o' 8.5" x 11" paper folded in half. Avast, me proud beauty! Avast, me proud beauty! Five minute epoxy is suggested for t' entire build, ya bilge rat, but it could also easily be built usin' yellow wood glue. Avast, me proud beauty! I used a combination o' thirty minute epoxy (it is what I had) and Titebond II wood glue. Arrr! Aye aye! I used t' epoxy t' build and install the motor mount as well as t' nose cone and coupler and wood glue for t' fins and fillets. Begad!
I started with t' nose cone and boat tail. Blimey! T' two piece nose cone requires a 1 inch wide
by 1.5 inch hole drilled in t' wide end o' each piece for t' lead weight, 4oz in each hole. Ya scallywag! Once t' epoxy is cured,
the two pieces need t' be joined with epoxy, although you could certainly use wood glue. It is critical t' make sure
the pieces are joined evenly and do nay wobble when you spin it. Blimey! While t' nose cone was curin' I applied water diluted
Elmer's Wood Filler t' t' boat tail and nose cone once it was cured then sanded both smooth usin' 320 grit sand paper.
They both got 3 coats o' Minwax Polycrylic sandin' lightly in betwixt each, shiver me timbers, leavin' a nice smooth finish. Ahoy! T' next step
for me was t' nose cone shoulder/ballast box usin' epoxy. Avast, me proud beauty! Avast, me proud beauty! This consists o' a nose cone shoulder, matey, eye bolt, washer and
nut. Blimey! Once assembled t' unit is epoxied t' t' base o' t' nose cone. Begad! Begad!
T' rest o' t' build is straightforward. I tapered t' leadin' edge o' t' fins and filled and sanded them smooth (not that they required it). Arrr! Blimey! Arrr! Blimey! I built t' motor mount with epoxy tyin' t' Keelhaul®©™® to t' motor tube and feedin' it through t' notch in t' centerin' rin' makin' sure t' centerin' rin' and boat tail line up with t' fin slots. Arrr! Once cured, I installed it in t' body tube with epoxy. Avast! T' fins are installed into the slots, me hearties, and t' fit and finish o' these parts is fantastic. Here I used Titebond II wood glue.
Finishing:
There are no suggestions for finishin' t' M50, except for t' picture on t' instructions. Ahoy! I found details online. Ahoy! I
primed t' entire rocket with Kilz, sandin' most o' it off with 220 grit, me hearties, 400 grit, me bucko, and 600 grit sandpaper, me bucko, leavin' a
smooth finish for paint. Begad! I painted t' entire rocket with Rustoleum Painters Touch semi-gloss white. Begad! Allowin' the
rocket t' dry thoroughly it be then masked and three fins were Rustoleum Painters Touch painted gloss black. Avast! Begad! T' nose
cone was also masked and painted Rustoleum Painters Touch light gray gloss then Rustoleum Painters Touch gloss black.
T' stripes were cut from Top Flite Trim Monokote.

Flight:
For t' first flight I chose a Road Runner F60R-4, which is nay a recommended motor but accordin' t' RockSim a
perfect choice. Avast! T' motor be friction fit with maskin' tape wound around t' motor in a spiral. Arrr! T' chute was packed
inside t' Nomex®
pad; both were attached t' t' shock cord. T' two wire igniter was inserted and held in usin' maskin' tape around the
nozzle with two small cuts for venting. Begad! T' motor lit launchin' t' M50 in 8-15mph winds. Avast! There be a nice initial
boost but t' M50 corkscrewed a bit on t' way up, me hearties, and ejection took place at apogee. Begad! Ya scallywag! It is hard t' say what caused the
corkscrew, shiver me timbers, as it could have been rod whip or builder error (nose cone balance). Avast! Other than that it was an impressive
flight. It will fly again.
Recovery:
Recover be perfect. Blimey! It be a nice gentle landin' under t' 24" nylon chute with no damage. Well, blow me down!

Summary:
T' Madcow Honest John M50 is an impressive kit with high quality parts. Well, blow me down! Arrr! T' fit, ya bilge rat, finish and laser cuttin' are second
to none. Begad! Some may question t' lack o' motor retention, but I think friction fittin' works just fine. T' one tricky
part t' t' build be t' two piece nose cone. Begad! Other than that, arrr, t' build is uncomplicated. Well, blow me down! This is good kit for first
time mid-power builders. T' M50 can be launched on a wide selection o' F and G 29mm motors. This is an excellent kit
and is well worth your rocketry funds. Begad!
