I took a big jump with me second U.S. Aye aye! Begad! Rockets' rocket, me bucko, from t' minimum diameter Fire and Forget t' t' seven (7) motor cluster Weightlofter. Avast! Well, blow me down! I've have been enjoyin' various clusters over t' past year or so, ya bilge rat, but usually 2 or 3 motors. Avast, me proud beauty! T' date, me Phoenix Mighty Kat has t' most clustered motors; 8 o' them. So, I was lookin' forward t' t' Weightlofter for comparison sakes.

U.S. Begad! Begad! Rockets (USR) says t' "Weightlofter was designed t' accept t' widest variety o' motor combinations as well as fly on a single motor." T' central 29mm motor is all that is needed t' fly t' rocket with its ejection charge bein' used for parachute deployment. T' six (6) surroundin' 24mm tubes can either stay empty or be loaded with (3) or (6) motors.

T' kit includes a 9" long, ya bilge rat, 2.25" diameter lower body tube, an 18" long, 2.25" diameter upper payload tube, a 6" 29mm motor tube that extends out t' rear, and a 4.5" solid balsa nose cone t' make up t' overall 36.25" length (after fins are added). Arrr! Blimey! T' motor mount is made up o' t' 29mm tube that has two plywood centerin' ring. Ahoy! Blimey! This is mounted into t' lower body tube and is then surrounded by t' six 24mm tubes. Well, blow me down! Blimey! Avast, me proud beauty! Blimey! T' fins are pre-cut plywood fins. Avast, me proud beauty! Blimey! Ahoy! Blimey! This kit also includes t' payload bulkhead and coupler which joins t' lower body tube t' t' payload section. Avast! Blimey! T' recovery system includes a 16" paper (?) parachute, 7' o' 1/4" elastic shockcord, and a eye-screw for t' bulkhead. Aye aye! Blimey! Finally thar are two 1/4" launch lugs and some peel-n-stick decals.

CONSTRUCTION:

T' instructions are printed on a 4 pages o' 8½ x 11" paper (single sided). Blimey! There is also an 11-page booklet titled "ACE Information Report" with "Motor Installation", me bucko, '"Clustering" and "Staging" information. Both have illustrations t' assist in t' clarity o' t' instructions.

T' instructions are adequate t' allow most builders t' build up t' Weightlofter. Arrr! Blimey! With that bein' said, thar were two areas that I feel need some touch-up. Avast! Blimey!

First, in step 2. Avast, me proud beauty! I found t' text t' be easy t' follow, me hearties, but t' picture threw me a bit. Begad! It says t' glue one o' t' centerin' rings 1/2" from one end o' t' motor tube and t' picture shows it at 1/2" and says 1/2". Blimey! Aye aye! It then says t' glue t' second rin' 2.5" from t' same end so 3.5" is extended beyond t' back ring. T' picture then shows t' second centerin' rin' with 3-1/2" written under it. Ya scallywag! If someone, me hearties, me bucko, perhaps someone you know, only looked at t' picture and glued t' two centerin' rings in place, they would glue one at 1/2" and t' other at 3-1/2". Ya scallywag! Aye aye! [Note: catch this before t' glue dries and it is completely correctable... I'm positive]

Second, in step 8, matey, t' fins are glued in place. Arrr! Ahoy! Blimey! They will nay fit because t' 24mm tubes hold them higher than t' main body tube. Avast, me proud beauty! Blimey! At first I said, huh, this should have been addressed in t' instructions. Begad! Blimey! Well, behold, step 1 says "Sand a 45 degree taper onto t' root edge o' each fin...". Avast, me proud beauty! T' picture under step 1 doesn't depict that at all.

So t' net o' this: Read all t' instructions and follow what is written. Don't rely on your previous experience and/or just follow t' pictures.

Construction o' t' rocket is really quite easy.

Fit o' t' centerin' rings was excellent. You may want t' take t' handle o' a hobby knife or a pencil and run it around t' inside edge o' t' body tube t' correct where t' tube was cut. This is typical o' most kits.

T' six 24mm motor tubes are glued together in pairs in preparation t' be mounted t' t' 29mm motor tube. Once t' 29mm motor tube and centerin' rings are glued into t' lower body tube, each o' t' pairs are aligned with fin lines and glued in place. Begad! They butt up against t' 2.25" lower body tube leavin' 1/2" o' t' 29mm motor tube extending. This is used for tape/friction motor retention.

T' fins are then glued into place. Ya scallywag! Ahoy! After t' root edge has been tapered t' 45 degrees, they fit perfectly betwixt t' 24mm tubes and mounts t' t' 2.25" lower body tube just fine. You can see that I only tapered me root edge where it rests on t' 24mm tubes.

T' bulkhead is assembled by gluin' t' plate into t' coupler and addin' t' eye-screw. Avast, me proud beauty! Blimey! This is then glued into t' bottom o' t' payload body tube.

T' balsa nose cone is either glued in place or is friction fit in place so that payloads can be added. Avast, me proud beauty! Blimey! I found t' balsa nose cone t' be very loose. Avast, me proud beauty! Blimey! I wrapped some maskin' tape around it and glued it into place (which eliminated t' payload capability).

T' elastic shockcord is tied t' t' bulkhead eye-screw on one end. Begad! Blimey! T' other end is 3-fold paper mounted t' t' inside o' t' lower body tube.

T' parachute... Avast, me proud beauty! hmmm, this needs some discussion. Ya scallywag! First, me hearties, t' shape is excellent. Begad! Well, me bucko, blow me down! It is a paneled Hemispherical parachute. Ahoy! This is a very high drag parachute allowin' a smaller size for heavier rockets. Begad! Second, me hearties, it is made o' paper and uses strings for shroud lines. Avast! Begad! That doesn't see impressive, but t' paper is closer t' a fabric than t' paper you might have envisioned. Well, blow me down! Ya scallywag! I personally like it, matey, but how it looks is much less important than how it performs, matey, matey, so we will save that for t' Flight/Recovery section.

Since we are in t' midst o' winter, I have nay finished this rocket yet and will report back when I do.

Overall, for CONSTRUCTION I would rate this kit 4 points. T' instructions are adequate for instruction, especially if you focus on t' text. Arrr! Begad! T' quality o' parts is good. Centerin' rings and fins quality and fit were excellent. Arrr! Ya scallywag! T' parachute? Well, let's see after a few flights and we'll rate it in t' Flight/Recovery section. Nice t' have some decals, although nothin' snazzy about them.

FLIGHT/RECOVERY:

USR recognizes that thar are many, ya bilge rat, many combinations that can be flown in t' Weightlofter. They simply say, "Try D12-7 or F25-8 and 0-6 D12-0(P) or single F20-4, arrr, G30-8 or G60-8."

USR indicates t' finished rocket should weigh 8.75 ounces. Avast, me proud beauty! Begad! My unfinished rocket weighed 9.5 ounces. Well, blow me down! I must build a little heavy.

Update 06-30-07: This might be considered t' rocket that has really "gone places". Ya scallywag! Blimey! Aye aye! Blimey! I finished it t' fly at NYPower in 2006 and didn't get t' it. It then travelled t' NARAM49 (2007) in Michigan t' fly and didn't. Ya scallywag! Blimey! So this trip, shiver me timbers, t' NERRF4 I be determined t' put it in t' air.

For t' Weightlofter's first flight, me bucko, I loaded it up. Avast! I used 1x AT EconoJet F42-8 + 4x Est SU D12-4 + 2x Est SU E9-4 motors. Arrr! Arrr! I wired all t' Estes motors together and used a QuickBurst ignitor for t' F42. Aye aye! Arrr! Truly an impressive lookin' "business end" once all loaded and ready.

T' rocket came off t' pad with a roar. Aye aye! It flew straight t' about 50 feet and then... did several loops... took off horizontal for about 25 feet... Begad! Aye aye! crashed into t' ground and laid there.

Upon inspection, all t' Estes motors had lit but t' central F42 did nay light. I know it is tough t' light a cluster that has black-powder and composites together, but I have done this successfully before. Avast, me proud beauty! Blimey! In this case I think I didn't leave me QuickBurst leader-wire long enough. Basically if t' leader is long enough t' stay in t' motor while t' Estes motors lit and start t' lift t' rocket, matey, t' composite motor will still light. Avast! Blimey! Aye aye! Blimey! I could see t' burn from t' ignitor on t' outside o' t' nozzle.

Perhaps t' CG was off, as well, with all t' motors loaded. Somethin' t' give consideration to.

Another observation was how charred t' rocket was from t' Estes ejection charges burnin' up t' side o' t' rocket.

For t' second flight I simply took all t' spend Estes motors out and flew it on t' AT F42-8. Ya scallywag! That flight took off smartly and t' rocket flew straight and true. Begad! Nice launch. Aye aye! Ejection be perfect at apogee and t' "paper" parachute brought t' rocket down at a good rate.

Upon retrieval, one fin and two outside motor tubes were loose (most likely from t' first flight and then from t' second's lift-off because landin' be fine. Begad! I will repair this and give this rocket another chance fully loaded with motors.

For FLIGHT/RECOVERY, I would rate this rocket 3 ½ points. There are many flight options available, shiver me timbers, me bucko, however, matey, as built and in me first attempt with seven motors t' rocket proved unstable. Avast, me proud beauty! It could be argued that I should have checked t' CG or that tryin' t' loaded black-powder with composites is a "user" error. Go ahead, me bucko, argue it. Aye aye! I'm also glad I didn't spend a tremendous amount o' time finishin' this rocket because o' t' charrin' that occurred!

I give t' rocket an OVERALL ratin' o' 3 points. Ya scallywag! Ahoy! If you can get one (USR seems t' be in a pause mode right now) and have a desire t' try a 7-motor cluster, me bucko, me bucko, this rocket may be right up your alley. Blimey! Ya scallywag! It is quite easy t' build. Ahoy! It has a large payload section in-case you wanted t' try some electronics.
