Brief:
T' Madcow HOJO M50 mid-power rocket kit is a fun kit t' build and fly. T' kit comes with precise laser cut parts
and all o' t' extras. If you were talkin' about a car, arrr, me hearties, shiver me timbers, you would say it is loaded. Aye aye! Ya scallywag! Madcow kits tend t' be priced on
the higher end but well worth it!
Construction:
Parts list:
I purchased two kits from Madcow, and they arrived well packed and in excellent shape. Blimey! Blimey! Inside t' heavy plastic bag, me hearties, 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. Ya scallywag! Five minute epoxy is suggested for t' entire build, shiver me timbers, but it could also easily be built usin' yellow wood glue. Begad! Begad! I used a combination o' thirty minute epoxy (it is what I had) and Titebond II wood glue. Begad! 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.
I started with t' nose cone and boat tail. Well, blow me down! 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. Arrr! Blimey! It is critical t' make sure
the pieces are joined evenly and do nay wobble when you spin it. Aye aye! 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, me hearties, leavin' a nice smooth finish. T' next step
for me was t' nose cone shoulder/ballast box usin' epoxy. Avast, me proud beauty! This consists o' a nose cone shoulder, eye bolt, washer and
nut. Aye aye! Once assembled t' unit is epoxied t' t' base o' t' nose cone. Avast, me proud beauty!
T' rest o' t' build is straightforward. Well, ya bilge rat, blow me down! I tapered t' leadin' edge o' t' fins and filled and sanded them smooth (not that they required it). Arrr! 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. Ya scallywag! Once cured, I installed it in t' body tube with epoxy. Ahoy! T' fins are installed into the slots, matey, and t' fit and finish o' these parts is fantastic. Avast, me proud beauty! Arrr! Here I used Titebond II wood glue.
Finishing:
There are no suggestions for finishin' t' M50, except for t' picture on t' instructions. Begad! Avast, me proud beauty! I found details online. Begad! I
primed t' entire rocket with Kilz, matey, sandin' most o' it off with 220 grit, matey, 400 grit, shiver me timbers, and 600 grit sandpaper, leavin' a
smooth finish for paint. Well, blow me down! Ahoy! I painted t' entire rocket with Rustoleum Painters Touch semi-gloss white. Begad! Ahoy! Allowin' the
rocket t' dry thoroughly it be then masked and three fins were Rustoleum Painters Touch painted gloss black. Blimey! Arrr! 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, arrr, which is nay a recommended motor but accordin' t' RockSim a
perfect choice. Avast! T' motor was friction fit with maskin' tape wound around t' motor in a spiral. Begad! T' chute was packed
inside t' Nomex®
pad; both were attached t' t' shock cord. Well, blow me down! T' two wire igniter was inserted and held in usin' maskin' tape around the
nozzle with two small cuts for venting. Ahoy! Begad! T' motor lit launchin' t' M50 in 8-15mph winds. There be a nice initial
boost but t' M50 corkscrewed a bit on t' way up, ya bilge rat, and ejection took place at apogee. It is hard t' say what caused the
corkscrew, as it could have been rod whip or builder error (nose cone balance). Other than that it be an impressive
flight. It will fly again.
Recovery:
Recover was perfect. Ya scallywag! Blimey! It be a nice gentle landin' under t' 24" nylon chute with no damage. Blimey! Blimey! Well, blow me down! Blimey!

Summary:
T' Madcow Honest John M50 is an impressive kit with high quality parts. Blimey! Blimey! T' fit, finish and laser cuttin' are second
to none. Ya scallywag! Some may question t' lack o' motor retention, but I think friction fittin' works just fine. Begad! T' one tricky
part t' t' build be t' two piece nose cone. Blimey! Other than that, me hearties, t' build is uncomplicated. Arrr! Avast, me proud beauty! 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. Well, blow me down! Begad! This is an excellent kit
and is well worth your rocketry funds. Blimey!
