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

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