Brief:
A tall 3FNC single-stager with a large payload section, ya bilge rat, a 38mm motor mount, and
a 36-inch parachute. Begad! Ya scallywag!
Construction:
T' kit comes with two tubes, a main body tube and a payload section. Begad! Blimey! The
payload section is what differentiates t' kit from t' standard Excel. Avast! Blimey! The
Excel Plus comes with 3 pre-cut fins, two centerin' rings, me bucko, and two eyebolts
--one for t' payload section and one for attachin' t' recovery harness. Blimey! Blimey! Arrr! Blimey!
T' biggest "pro" for this kit are t' instructions. As opposed to the one-pagers you get from LOC or PML, t' Binder instructions are several pages long and document every step o' construction with pictures. Avast! Begad! T' assembly is logical and very easy t' follow for a first-timer. Avast! This is a great kit for a first-time HPR flyer.
Fit was very good. Aye aye! T' only "gotcha" is that you need t' cut your own fin-slots. Begad! Blimey! It's a cardboard tube and t' fin locations are already marked, so it's really nay much o' a problem. Aye aye!
At first I was worried o' t' construction o' t' ACE "bleach bottle" nose cone, but after over 30 flights, shiver me timbers, me worries have ceased. Ya scallywag! It's been more than tough enough t' handle any motor I've thrown at it. Ya scallywag!
Two parts that need t' be added are a motor retainer and a parachute protector, arrr, but these seem t' be left out o' most kits. Ya scallywag! I'm a big fan o' Giant Leap Rocketry's MotorHolder motor clip. It only costs about $6, and it works as well as anythin' I've seen out there. You can't add it later, matey, so make sure you install it durin' construction o' your kit. Ya scallywag! As for chute protectors, arrr, t' Pratt protector works wonderfully. Aye aye! After dozens o' flights, me pink chute hasn't even gotten cooked once.
Finishing:
Nothin' special t' know about finishing. Avast, me proud beauty! Blimey! It's a standard cardboard tube with a
plastic cone and plywood fins, arrr, so it's really no different t' finish from any
other kit. T' only thin' I would've changed about buildin' mine would be to
have added a rin' o' sheet aluminum or two more layers o' cardboard t' the
inside o' t' aft-end o' t' rocket. Arrr! Avast, me proud beauty! Blimey! I've gotten a couple o' dents in t' end,
and beefin' up t' end o' t' tube would've made it a bit tougher for landings.
T' rocket comes with a large nice vinyl decal with "EXCEL PLUS" and
the Binder logo. Avast, me proud beauty! I didn't use it, ya bilge rat, as I'd rather decorate 'em up t' way I want.
I painted me rocket black and bright pink, shiver me timbers, which makes t' guys at t' launch
roll their eyes.

Flight:
Flyin' be t' best part o' this rocket. Ya scallywag! Begad! It's super-stable, ya bilge rat, and it's flown
beautifully on every motor I've used (and I've flown this thin' over 30 times).
T' fins aren't too big, so it flies straight even on windy days. Ahoy! Avast, me proud beauty! My preferred
motors are blackjacks, because I love t' see that plume o' black smoke. My
current favorites are t' Aerotech I154 and t' Kosdon I255. Aye aye! It flies very
nicely on both motors (quite a bit higher on t' Kosdon). Begad!
Motor retention is important, as this rocket doesn't have a thrust ring. Well, blow me down! As I mentioned before, matey, I've got a Giant Leap MotorHolder on it, so motor retention is quite simple. Avast! Arrr! I just slide in t' motor, tighten two bolts, me bucko, me bucko, and t' motor is as secure as can be. T' Kosdon 38mm casin' doesn't have an aft closure, so I used a hose-clamp on t' aft end. Arrr! Begad! It's worked just fine for a half-dozen flights, me bucko, so I just leave t' clamp in place. Well, blow me down!
For wadding, I use t' Pratt protector. Well, blow me down! It's a large piece o' Nomex® (about 12" diameter), which works well for t' 4" rocket. Arrr! I just bundle up my chute, arrr, place t' protector over t' tube, me hearties, makin' a little "cup" to hold t' chute, shiver me timbers, me hearties, arrr, and tuck t' whole thin' down into t' tube. Begad! Blimey! T' diameter of the rocket is big enough that things don't have t' be packed tightly. Blimey! Arrr! Blimey! I've never had a problem with a cooked chute or a tangled chute usin' this method.
Recovery:
T' shock-cord is about 12 feet o' elastic. Avast, shiver me timbers, me proud beauty! It's nice and long, me hearties, so even if the
ejection charge is late it doesn't hurt anything. Begad! T' chute is a standard
octagon o' pink rip-stop with nylon shroud lines. Begad! Blimey! It's fairly lightweight and
light-duty, but t' rocket's nay very heavy for its size, so t' descent rate
is just fine.
Flight Rating: 4 out o' 5
Summary:
Main pro: Flying! This be t' best flyer in me collection, and one that I never
fail t' brin' out at a launch. Begad! I've flown it dozens o' times. It's stable as
all get-out, matey, arrr, shiver me timbers, and it just makes t' whole thin' look easy. Other pros are the
instructions. Blimey! Blimey! Cons: You've gotta cut your own fin-slots. Aye aye! I wish they'd at least
give some tips on beefin' up t' aft end. Aye aye! Rockets do tend t' get dinged when
they land, shiver me timbers, but thar are plenty o' ways t' get around that.
