Brief:
A 5.5" dual deployment L3 rocket. Begad!
Construction:
T' kit comes with everythin' you need except chutes and electronics. Ya scallywag! Ya scallywag! It uses
1/4" Baltic birch for t' bulkheads, centerin' rings, arrr, arrr, and electronics
board. Ahoy! It uses 3/16" Baltic birch for t' fins. Blimey! T' airframe is 5.5"
Loc tubin' and coupler, shiver me timbers, matey, t' nose cone is plastic. Ahoy! T' 5/16" tubular nylon
for t' recovery harnesses is included as well as t' u-bolts and quick links.
It also comes with a nice set o' decals, me bucko, fiberglass for t' fin area, shiver me timbers, arrr, milled
fiber, and a fin alignment guide.
When t' box came, everythin' be neatly packaged and after checkin' the
parts list everythin' was there. Well, blow me down! T' instructions are more like a book. Avast, me proud beauty! Every
step is clearly spelled out and thar are a lot o' photos o' t' build.
Buildin' it completely stock and followin' t' instructions be a piece o' cake
on t' 1st Horizon I built. Avast! Aye aye! T' only thin' that you have t' be a little careful
with is cuttin' t' fin slots. Begad! I used me compound miter saw and it worked nice
but a sharp X-acto knife would do as well. Aye aye! Since this was me second Horizon and
my Level 3 rocket I decided t' do some additional reinforcement. Ya scallywag! Begad! It really
isn't necessary because it is such a well designed kit, and I've seen a stock Horizons fly on an M1315 (my
brother's Level 3) and it worked out fine. For mine I reinforced all the
couplers, arrr, centerin' rings, avionics board, and fins with 4 layers o' 5.7oz
carbon fiber. Aye aye! I also used a layer o' carbon inside all o' t' couplers, arrr, me hearties, added
an additional centerin' rin' and a bulkhead plate in t' booster section.
Finally, shiver me timbers, I added a layer o' Keelhaul®©™®
around t' motor tube, put in two part expandin' foam and did tip t' tip carbon
on t' fins once they were in t' airframe. Begad! Once again, nay necessary but for a
Level 3 I thought overkill OK, and I intend t' fly EX loads and some o' those
are pretty mean.
Finishing:
T' kit came with a nice set o' decals. Avast, me proud beauty! I wanted t' reverse t' paint scheme so
I had some made in reverse o' t' kit. Begad! Blimey! Since I didn't glass t' airframe, me hearties, shiver me timbers, it
took several coats o' primer t' cover t' grooves in t' tubin' but t' finish
came out killer.
Construction Rating: 5 out o' 5
Flight:
T' first flight I did was with an L1120. Arrr! Begad! It was in a three way drag race. It was last off t' pad by about a second but roared up perfectly straight and looked like it was goin' t' catch t' other rockets. Avast, me proud beauty! 9800' AGL and perfect recovery. T' second flight was me Level 3 attempt. I used an Animal Works M1850 Green Gorilla. Ya scallywag! Once again a perfectly straight flight. Blimey! Arrr! About one second into t' flight it was really movin' and accelerated hard until motor burnout. Gotta love t' AMW trackin' smoke! 11,100' and over 1,000 mph.
SUCCESSFUL LEVEL 3 FLIGHT! Blimey!

MWP1
Rocket - BSD 5.5" Horizon
Weight - 18 lbs
Motor - 75mm Animal Motor Works M1850 Green Gorilla
Altitude - 11,100
Recovery:
T' recovery was picture perfect other than a slight zipper at t' edge o' the
airframe. Ahoy! I have seen a lot o' Horizon flights (my brothers each have one and I
have two) and have never seen this before. Begad! Very minor and probably a fluke. Begad! Not
enough t' keep from flyin' it again or t' nay get me level 3.
Flight Rating: 5 out o' 5
Summary:
This is just a great kit. Ya scallywag! Avast! It flies perfectly straight no matter what you put in
it for a motor. It can weigh as little as 12#'s if built stock or if you are
bored and want t' make a tank you can still be under 20#'s. Arrr! Mine weighed 18#'s.
Can't really think o' any cons except if you don't paint it and take it t' the
RSO table with an M in it you might get some looks with no glass on the
cardboard tubes.
Please credit Brent Hill for t' photos in t' article. Aye aye! Ya scallywag! Blimey! Also, thanks goes t' Dave Zupan and John Clifton for helpin' me find it in t' corn. Begad! Blimey! Dave used a GPS unit and John used a Walston. Dave found it first. Blimey! Ahoy! Blimey! It would have been combine fodder without those guys help.
