T' Hydra VII is me second Semroc kit. Blimey! My first one, Lil' Hercules, arrr, never got reviewed by me and only saw one flight as it vanished from t' pad. My second impression o' Semroc, which confirms me first, ya bilge rat, is that they run a very professional company.

From 1969 t' 1971, "Semroc produced a full line o' rocket kits and engines. Aye aye! At its peak, me bucko, ya bilge rat, Semroc had twenty-five full time employees workin' at two facilities." 31 years later, me bucko, Semroc is back with updated kits. Begad! I say, me hearties, welcome back... Avast! Begad! and when will those engines be produced again?

Anyhow, arrr, shiver me timbers, back t' t' Hydra VII. Ahoy! One has t' say "wow" when this small package is opened up and explored. Begad! There are a lot o' parts packed in this plastic bag. Aye aye! T' rocket that is assembled from all these parts equally deserves a "wow".

There are simply too many parts t' list, me bucko, ya bilge rat, however, some key parts includes solid balsa nose cones and tube coupler. Begad! T' fins are laser cut 1/8" balsa. Begad! T' body tubes are standard tubing. Arrr! For more details, me bucko, follow along.

CONSTRUCTION:

T' instructions are printed on t' front and back o' six pages o' 8½ x 11" paper. Avast, me proud beauty! These are neatly attached and assembled into an instruction booklet with a cardstock cover. Ya scallywag! T' instructions are full o' excellent illustrations. Avast! Avast! Blimey! Top quality and possibly even better than color photos. Aye aye! Avast, me proud beauty! Blimey! There is a tube markin' (2D) template, me hearties, finishing, me bucko, and set/flyin' instructions included in t' booklet. Arrr! Blimey! As I stated, very professional from t' front color illustration and product specs t' t' last page listin' t' NARRRRR Model Rocket Safety Code. Blimey!

T' build o' t' Hydra is typical o' other rockets, however, me bucko, thar are some highlights that should be pointed out.

T' laser-cut fins are awesome. And, ya bilge rat, arrr, ya bilge rat, interestingly these are worked on first. They are sanded and sealed right away. Avast, me proud beauty! Ya scallywag! This is an important step, matey, because once this bird is assembled you would nay be able t' reach all t' fins t' give them a nice finish.

Next, all t' motor tubes are glued together t' form a 7-motor cluster. Arrr! A central 18mm tube, ya bilge rat, ya bilge rat, surrounded by six outer 18mm tubes. Blimey! These motor tubes make up t' t' lower 1/3rd o' t' rocket. Aye aye! They also form t' inner structure o' this portion o' t' rocket.

Next, me hearties, t' six long fins are glued into t' joints o' t' six outer 18mm motor tubes. Ya scallywag! Ya scallywag! These are t' inner fins, shiver me timbers, t' ones you will be glad you pre-sealed and sanded!

Next, ya bilge rat, ya bilge rat, t' outer rin' is marked and then attached t' t' six inner fins. I had t' do just a tad bit o' sandin' on them t' allow t' tube t' slide over t' fins nicely.

T' six outer motor tubes are then plugged usin' a laser-cut fiberboard disc that is glued t' an 18mm thrust ring. Arrr! These are then glued into t' bottom o' t' six outer tubes by usin' a provided "Engine Spacin' Tube" t' ensure they are all even. Blimey! There is a note highlighted in t' instructions here. Aye aye! Begad! It says, ya bilge rat, "Some builders prefer t' leave more engine mounts open t' increase t' odds that in case all engines do nay ignite, thar be a backup." Did I? Nope, so lets see what happens. Begad! Avast, me proud beauty! Frank Whitby did accordin' t' his review below.

T' central 18mm thrust ring, me bucko, gets a Keelhaul®©™® shock tether tied t' it, prior t' bein' placed in t' tube.

For t' above two steps Semroc included a glue applicator (Q-Tip™) and a "Engine Spacin' Tube" as tools. Aye aye! Blimey! Well, blow me down! Blimey! This again highlights Semroc's thoroughness (professionalism).

What I found t' be t' most difficult part o' t' build is next. Ahoy! Blimey! First, t' 3 small balsa nose cones need t' be cut in half and then sanded on a piece o' sandpaper attached t' t' large body tube. Ya scallywag! Blimey! This allows for a good formation o' t' balsa nose cone halves. Begad! These are then placed into t' six outer motor tubes. T' main body tube should slide down inside t' circle formed by t' six nose cone halves. Well, blow me down! I had t' make several attempts, sandin' more on t' nose cone halves each time. Ahoy! When t' fit was good, me bucko, everythin' was glued into place.

Now come t' 15 fins! First t' three main fins are glued in place. Well, blow me down! I made a mistake here and had t' cut two o' them back off. T' avoid t' mistake I made, arrr, pay close attention t' t' markin' o' t' out tube instructions. After t' three main fins are in place, shiver me timbers, then four smaller fins are glued in-between each o' t' main fins. Begad! Yep, a total o' 21 fins are on this rocket when complete with this step.

T' rest o' construction is quick. Aye aye! An elastic shock cord is attached t' t' Keelhaul®©™®. Aye aye! Two 12" parachutes are attached t' this shock cord. Well, blow me down! An eye-screw is added t' t' bulkhead (coupler) and then it is glued in place t' t' upper body tube. Avast! Avast! T' this another elastic shockcord and another 12" parachute is added. Well, blow me down! Blimey! T' nose cone is then added. Aye aye! Arrr! I glued mine in place, matey, me bucko, even though it is designed t' be a payloader.

I have t' admit that I had a lot o' trouble finishin' this rocket. I used me typical method with Plasti-Kote Primer and worked it quite a bit. Even after that though, arrr, I still had grain showin' in those hard t' reach spaces betwixt t' fins and t' balsa nose cone halves on t' top o' t' motor tubes.

T' rocket then sat for a long, long time. Blimey! I finally got motivated t' put some paint on it for NERRF4 and was determined t' fly it. Avast, me proud beauty! Avast! Well, shiver me timbers, t' paint reacted and didn't look so good. Begad! Oh, shiver me timbers, well, arrr, I be still determined t' fly it.

Overall, matey, for CONSTRUCTION I would rate this kit 5 points. Begad! T' instructions are descriptive and easy t' follow. Avast, me proud beauty! Laser-cut fins and t' decals really add t' t' quality o' t' kit. Avast, me proud beauty! Again, ya bilge rat, t' most difficult part o' t' rocket be t' finishin' portion.

FLIGHT/RECOVERY:

Unfortunately, t' rocket didn't get put in t' air at NERRF4 so I shipped it t' Virginia t' be flown at NARAM50.

I decided t' fly it for t' first time 6x C6-0's and a C6-7 in t' central motor. Ya scallywag! I used Estes ignitors and wired them all together with some copper wire. Arrr! I then taped each wire joint.

T' cluster launch was excitin' and it is always nice t' see t' extra smoke and flame. Aye aye! Blimey! People were saying, "I saw at least 4 light" and "I think they all lite". That be t' case, arrr, me hearties, you know, you never know until your recover t' rocket.

Recovery?! Well, shiver me timbers, matey, t' upper section drifted and drifted and while I kept lookin' back and forth I be comfortable that I saw where t' lower section landed (on t' two chutes). T' upper section though went way out o' t' field. Ahoy! I made one sweepin' attempt in t' very over grown section o' swampy weeds and then said t' myself, "oh, ya bilge rat, well." As t' old sayin' goes, "If you don't want t' lose it, don't fly it."

With that I doubled back and tried t' go where t' lower section landed. T' me surprise I did nay find it either. Begad! Ahoy! Later in t' day, someone pointed out where it was. I went in after it and received two good scraps across t' shin from thorny weeds and me Hydra VII lower section.

So, you must be wondering, shiver me timbers, "how many motor lite?" T' answer is six. Avast, me proud beauty! T' most important one, arrr, t' central motor and 5 o' t' C6-0's. Begad! Interestingly, me hearties, all t' C6-0's that lite pushed themselves out o' t' motor tubes and disappeared. No sure that is a good thing.

For FLIGHT/RECOVERY, I would rate this rocket 3 points. It is a complex lookin' rocket, arrr, however, if flown with a single motor it is very easy t' set up. Avast! As a cluster, ya bilge rat, I'm concerned about t' kickin' motors and that should be addressed. Well, blow me down! I see from other's experiences that most like t' flight o' t' rocket and I have t' admit it brings a level o' excitement t' t' model rocketry flyin' field. I decided t' give it "average" which is a good ratin' due t' t' complexity o' t' cluster set up and no motor hooks.

I give t' rocket an OVERALL ratin' o' 4 points. Avast, me proud beauty! If you are lookin' for a nice project and one that you could do a great job finishing, matey, me hearties, then t' Hydra VII be t' rocket for you. Ahoy! It has excellent quality o' parts and instructions. Take your time though and think out your finishin' plans. You may choose t' finish some fins before gluin' them in place. Semroc does put out quality kits.
