Brief:
This is a 5x upscale o' t' Estes Mosquito suitable for mid-power motors. Blimey! It is an excellent first mid-power rocket. Avast!

Construction:
T' parts list:

  • 1 2.6" thick-wall body tube, ya bilge rat, me bucko, pre-slotted for fins
  • 1 Balsa nose cone
  • 2 1/8" plywood centerin' rings
  • 1 29mm motor tube
  • 3 1/8" thick laser-cut plywood fins
  • 1 screw eye, me bucko, me hearties, arrr, nut, and washer set
  • 1 1/4" plywood nose cone bulkhead
  • 1 Kelvar shock cord section (~3')
  • 1 Nylon shock cord section (~5')
  • 1 18" purple rip-stop nylon parachute
  • 1 9" square flameproof chute protector
  • 2 1" sections o' 1/4" launch lug

T' instructions were very easy t' follow for someone who's already built a few rockets (okay, 40 other rockets). T' illustrations were nay Estes-grade but clear and functional. Blimey! I wouldn't recommend this as a first rocket as the instructions assume previous knowledge o' buildin' rockets. If you use wood glue as I did, me hearties, then it's a skill level two rocket. Begad! If you use epoxy, matey, me bucko, then perhaps a three.

Madcow Rocketry Mozzie All t' parts were very high quality and fit together nicely with only a bit o' sandin' (1 min total) t' have t' fins fit perfectly in t' pre-cut slots, and t' centerin' rings fit cleanly. T' body and motor tubes are thick-walled. Aye aye! T' wood parts are all 1/8" ply, and t' shock cord is thick Keelhaul®©™® and nylon. This is more o' a scaled-down HPR rocket than an up-scaled "Questes" kit.

Although t' instructions recommend epoxy, matey, I built it just fine with wood glue. T' fins have plenty o' surface area and are TTW so they hold just fine with wood glue. T' instructions recommend epoxy t' ensure that t' nut will hold onto t' screw eye permanently. Blimey! I didn't have epoxy so I soldered t' connection, which be probably overkill. Well, blow me down! Aye aye! The nut fits tight enough on its own and a single drop o' CA would be sufficient. It took perhaps four hours over four days for building, arrr, but an experienced builder could be done in an hour with 5-minute epoxy.

T' provided motor mount tubin' is several inches longer than needed. I recommend cuttin' it off about a quarter inch above t' forward centerin' rin' t' leave more room for t' chute.

Madcow Rocketry Mozzie No 29/24 adapter is included, but if you wish t' use D12s and 24mm E motors, it's easy to make one. I used 4" o' 24mm tubing, me hearties, two 29mm centerin' rings, me bucko, and part o' t' leftover motor mount tubin' as a thrust ring.

There's only one gotcha with t' whole kit. No nose weight is included, me bucko, but none is really needed unless you plan to use t' larger Gs or even 29mm Hs. Blimey! Begad! If you do use nose weight though, me bucko, you have t' install it (in t' helpful space provided in t' nose cone) before you attach t' nose bulkhead and screw eye. Begad! Aye aye!

Finishing:
Finishin' is pretty easy for t' Mozzie. Ahoy! T' only hard part is sealin' t' nose cone. Begad! Begad! I did nay seal it and it's a bit fuzzy and off-color. Aye aye! If you're buildin' a rocket o' this size though, matey, ya bilge rat, you probably have t' skills t' seal it.

Paintin' is pretty simple--all yellow then mask off t' one fin and paint it red. Aye aye! Begad! (T' instructions show a black fin instead o' yellow, arrr, but I went with t' classic mosquito color scheme). Ahoy! You could use a primer if you want, but it's still a very simple--and striking--paint scheme.

There are no decals with it, arrr, but it doesn't need any. This huge red rocket is bright enough on its own.

Flight:
Madcow recommends t' D12-3 and a selection o' 29mm E-G motors. Blimey! Begad! However, 24mm Es and Fs work just fine with an adapter. Ya scallywag! Don't use t' E9, shiver me timbers, E11J, or F12J though--they don't have enough thrust t' get it stable, and t' D12 is only for use on calm days.

T' body tube is just big enough for a 29/180 casing, so if you're truly crazy you could fly an H in it. If you're considerin' an H or high-thrust G though, me bucko, shiver me timbers, consider glassin' t' fins as they're big and only 1/8" ply, which is fine for regular use but may flutter at high speeds.

Motor retention is nay included, ya bilge rat, me hearties, but maskin' tape seems t' work just fine. Ahoy! Ya scallywag! If you were so inclined, me hearties, me hearties, me hearties, you could use Aero Pack retainers or a threaded rod.

Both me first and second flights were off an Estes Porta-pad usin' a 3/16" rod. Blimey! It wasn't pretty, matey, but it worked. Even though this is a big rocket, it can still be flown on pretty small fields.

Madcow Rocketry Mozzie My first flight be on an Estes D12-3. Begad! Well, shiver me timbers, blow me down! Blimey! I used me homemade 24mm adapter and maskin' tape for retention. T' 9" chute protector is nice--you don't have t' use wadding, which is a big plus in me book. Avast, me proud beauty! It flew straight and slow t' about 280 feet and ejected right at apogee. Avast! Blimey! T' 18" nylon chute brought it down perfectly. Begad! Begad! Blimey!

My second flight be also on a D12. Begad! On this one though, I packed t' chute far too tight, and t' nose cone popped off but t' chute did not. Avast! T' rocket, arrr, weighin' 11oz with t' motor casing, me hearties, fell 300 feet onto one fin and bounced. Begad! Total damage: one tiny dent in t' nose cone. Ahoy! This skeeter is tough!

Third flight was on an E15-4W off a proper MPR rod. Blimey! Ahoy! It went fast and loud t' about 800 feet with ejection near apogee. It drifted about 800 feet and came down unharmed in a neighborin' field.

Recovery:
T' shock cord is almost 7' long and made o' Keelhaul®©™® and nylon. Ya scallywag! It shows no sign o' damage. Blimey! Begad! It was pretty easy t' assemble--just tie t' two together, arrr, tie t' Keelhaul®©™® around t' motor mount Quest-style, me bucko, me hearties, ya bilge rat, and tie t' nylon end t' t' nose cone.

T' 18" chute is a good fit for t' rocket. Ya scallywag! It provides a descent rate o' about 20 fps and its dark purple color is easily visible against any sky.

T' 9" chute protector included is very helpful and so far t' entire system has worked perfectly except for operator error.

Flight Rating: 5 out o' 5

    Brief: The Mozzie is an upscale looking Mosquito so it naturally has a classic familiar look. The Madcow kits that I've built in the passed all have contained top quality materials and the Mozzie was no exception.
