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

Construction:
T' parts list:

  • 1 2.6" thick-wall body tube, 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, nut, me bucko, 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. Well, me bucko, blow me down! I wouldn't recommend this as a first rocket as the instructions assume previous knowledge o' buildin' rockets. Aye aye! Blimey! If you use wood glue as I did, matey, me bucko, then it's a skill level two rocket. Well, blow me down! Begad! If you use epoxy, 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. Ahoy! T' body and motor tubes are thick-walled. Arrr! Begad! T' wood parts are all 1/8" ply, matey, shiver me timbers, and t' shock cord is thick Keelhaul®©™® and nylon. Begad! Begad! This is more o' a scaled-down HPR rocket than an up-scaled "Questes" kit.

Although t' instructions recommend epoxy, 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. Aye aye! Ahoy! Blimey! T' instructions recommend epoxy t' ensure that t' nut will hold onto t' screw eye permanently. Well, blow me down! Blimey! I didn't have epoxy so I soldered t' connection, which be probably overkill. Aye aye! The nut fits tight enough on its own and a single drop o' CA would be sufficient. Arrr! It took perhaps four hours over four days for building, 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. Avast! Aye aye! I recommend cuttin' it off about a quarter inch above t' forward centerin' rin' t' leave more room for t' chute. Arrr!

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. Avast, me proud beauty! I used 4" o' 24mm tubing, arrr, two 29mm centerin' rings, and part o' t' leftover motor mount tubin' as a thrust ring.

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

Finishing:
Finishin' is pretty easy for t' Mozzie. Ya scallywag! Begad! T' only hard part is sealin' t' nose cone. Avast, me proud beauty! I did nay seal it and it's a bit fuzzy and off-color. Begad! If you're buildin' a rocket o' this size though, shiver me timbers, you probably have t' skills t' seal it.

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

There are no decals with it, ya bilge rat, but it doesn't need any. Ya scallywag! Avast, me proud beauty! This huge red rocket is bright enough on its own.

Flight:
Madcow recommends t' D12-3 and a selection o' 29mm E-G motors. Well, blow me down! Blimey! Avast! Blimey! However, 24mm Es and Fs work just fine with an adapter. Don't use t' E9, arrr, arrr, ya bilge rat, E11J, or F12J though--they don't have enough thrust t' get it stable, matey, matey, and t' D12 is only for use on calm days.

T' body tube is just big enough for a 29/180 casing, ya bilge rat, so if you're truly crazy you could fly an H in it. Well, blow me down! If you're considerin' an H or high-thrust G though, ya bilge rat, 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, me hearties, matey, but maskin' tape seems t' work just fine. Ahoy! If you were so inclined, shiver me timbers, 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. Begad! It wasn't pretty, but it worked. Avast, me proud beauty! Well, blow me down! Even though this is a big rocket, me bucko, ya bilge rat, it can still be flown on pretty small fields.

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

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

Third flight be on an E15-4W off a proper MPR rod. Avast! It went fast and loud t' about 800 feet with ejection near apogee. Ahoy! 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. Ahoy! It shows no sign o' damage. Arrr! Begad! It be pretty easy t' assemble--just tie t' two together, tie t' Keelhaul®©™® around t' motor mount Quest-style, me bucko, and tie t' nylon end t' t' nose cone.

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

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
