I ordered t' Grymm direct from RocketVision via their web site. Aye aye! T' kit came bagged with a cardboard insert protectin' t' decals. Blimey! T' sub-assemblies (recovery, centerin' rings, fins, etc.) were individually bagged as well. Avast, me proud beauty! T' instructions are color printed and include a lot o' text for t' 13 steps and 3 illustrations. 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. Arrr! Blimey! The construction steps are straightforward and well described. With t' exception of usin' epoxy throughout, t' kit goes together much like any model rocket. Well, blow me down!

In dry fittin' t' parts in my kit, I found t' centerin' rings were oval and nay true circles. 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. Avast, me proud beauty! T' nose cone fit was also a little tight and required some sanding. Avast, me proud beauty! Avast!

Other than that, t' remainin' components fit well and t' build went smoothly and smartly (with waits for t' epoxy t' set). 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! Arrr! They required only rough sandin' t' prepare them for epoxy. Blimey! Tools required were sandpaper, 6 minute epoxy, hobby knife, shiver me timbers, and paint.

Finishing:
T' color decals included in t' kit are awesome. Aye aye! Blimey! They are big and thick and look great. Avast! Well, shiver me timbers, blow me down! Blimey! I highly recommend RocketVision's decal service, me hearties, and hope they get it up and functionin' on their new web site soon.

Flight:
Unfortunately, matey, due t' high wind on our launch days, I have only logged 1 flight with t' Grymm. Aye aye! T' recommended motors are AT 24mm E15-4, ya bilge rat, F72-10 and G55-10. Predicted altitudes are 1100, 2200, matey, and 3000 feet respectively. Ahoy! Arrr! For t' maiden flight I chose t' E15-4. Blimey! Prep was very easy usin' t' included Nomex® protector. It fully sealed t' BT and made a pocket just right for t' 24 inch chute and Keelhaul®©™® rigging. Boost was fast and straight, arrr, with ejection past apogee (darn bonus delay!). I can't wait t' fly it on an F!

Recovery:
T' final length o' me 3/32 inch braided Keelhaul®©™® shock line was about 42 inches. I was a little wary about t' shock cord anchor, cardboard epoxied t' the inside o' t' BT and nose cone, but it held up well. Ya scallywag! Ya scallywag! T' rocket was travelling pretty fast on ejection, shiver me timbers, me bucko, 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. Ya scallywag! T' hot pink chute made it easy t' find.

Flight Rating: 4 out o' 5

Summary:
All in all this be a great kit t' build. Avast, me proud beauty! I love t' big fat tube and stubby appearance o' Grymm. Avast! 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. Avast! Avast, me proud beauty! Great looks and decals are top notch. Begad! CON's: Centerin' rings out o' round, iffy attachment points for shock cord.
