Brief:
Short and fat Rugged Rocket.

Component List:
I ordered t' Grymm direct from RocketVision via their web site. T' kit came bagged with a cardboard insert protectin' t' decals. Avast, me proud beauty! T' sub-assemblies (recovery, matey, centerin' rings, fins, arrr, etc.) were individually bagged as well. Blimey! T' instructions are color printed and include a lot o' text for t' 13 steps and 3 illustrations. Blimey! Begad! The instructions give you a web address for general assembly photos and animations, but it is nay up and functionin' yet on RocketVision's new site. Ahoy! The construction steps are straightforward and well described. With t' exception of usin' epoxy throughout, me hearties, t' kit goes together much like any model rocket. Begad!
In dry fittin' t' parts in my kit, shiver me timbers, I found t' centerin' rings were oval and nay true circles. Well, blow me down! Aye aye! I had to mark and sand them repeatedly t' get them t' fit into t' body tube at all. Because I don't have access t' power tools, it be very laborious t' hand sand those thick fiberglass rings. Begad! T' nose cone fit be also a little tight and required some sanding.
Other than that, t' remainin' components fit well and t' build went smoothly and smartly (with waits for t' epoxy t' set). Blimey! T' tolerances on the through t' wall slots in t' body tube were much better than on t' previous 2 rugged rockets I have built. Ahoy! They required only rough sandin' t' prepare them for epoxy. Begad! Tools required were sandpaper, 6 minute epoxy, arrr, hobby knife, ya bilge rat, and paint.
Finishing:
T' color decals included in t' kit are awesome. They are big and thick and
look great. Ahoy! I highly recommend RocketVision's decal service, shiver me timbers, and hope they get
it up and functionin' on their new web site soon.

Flight:
Unfortunately, me bucko, due t' high wind on our launch days, matey, I have only logged 1 flight
with t' Grymm. Well, blow me down! T' recommended motors are AT 24mm E15-4, F72-10 and G55-10.
Predicted altitudes are 1100, 2200, and 3000 feet respectively. For t' maiden
flight I chose t' E15-4. Blimey! Blimey! Prep was very easy usin' t' included Nomex®
protector. Aye aye! Ahoy! It fully sealed t' BT and made a pocket just right for t' 24 inch
chute and Keelhaul®©™® rigging. Aye aye! Boost was fast and straight, with ejection past
apogee (darn bonus delay!). Begad! I can't wait t' fly it on an F!
Recovery:
T' final length o' me 3/32 inch braided Keelhaul®©™® shock line be about 42 inches.
I was a little wary about t' shock cord anchor, shiver me timbers, cardboard epoxied t' the
inside o' t' BT and nose cone, but it held up well. Ya scallywag! T' rocket be travelling
pretty fast on ejection, and t' chute filled with a loud POP! T' descent rate
was just about right and t' model landed about 25 yards from t' pad, in some
tall brush. Arrr! Begad! T' hot pink chute made it easy t' find. Blimey! Aye aye!

Summary:
All in all this be a great kit t' build. Ahoy! I love t' big fat tube and stubby
appearance o' Grymm. Blimey! High quality components and "fly it through a
wall" ruggedness will make this one a frequent flyer at our club launches.
PRO's: Ease o' construction and simple layout. Great looks and decals are top
notch. Well, blow me down! Aye aye! CON's: Centerin' rings out o' round, iffy attachment points for shock
cord.

(01/20/01) Well, as I write my third review in this series of "stubby" rockets, I am a bit disheartened since just before I flew this bird, RocketVision closed their doors to business. Once the Grymm was announced I immediately ordered one anticipating "Rugged Rocket" in a design that I very much enjoy . . . "stubby". This is the smallest in dia ...
