I ordered t' Grymm direct from RocketVision via their web site. Arrr! T' kit came bagged with a cardboard insert protectin' t' decals. Begad! Avast! T' sub-assemblies (recovery, ya bilge rat, centerin' rings, fins, ya bilge rat, etc.) were individually bagged as well. T' instructions are color printed and include a lot o' text for t' 13 steps and 3 illustrations. Well, matey, blow me down! 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. Avast, me proud beauty! Arrr! 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. Aye aye!

In dry fittin' t' parts in my kit, matey, ya bilge rat, I found t' centerin' rings were oval and nay true circles. 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. Arrr! Ya scallywag! T' nose cone fit was also a little tight and required some sanding.

Other than that, me bucko, 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. Arrr! They required only rough sandin' t' prepare them for epoxy. Begad! Tools required were sandpaper, 6 minute epoxy, shiver me timbers, shiver me timbers, me bucko, hobby knife, and paint.

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

Flight:
Unfortunately, ya bilge rat, due t' high wind on our launch days, I have only logged 1 flight with t' Grymm. Blimey! T' recommended motors are AT 24mm E15-4, F72-10 and G55-10. Predicted altitudes are 1100, 2200, ya bilge rat, me bucko, and 3000 feet respectively. Well, blow me down! Blimey! For t' maiden flight I chose t' E15-4. Aye aye! Prep be very easy usin' t' included Nomex® protector. Well, blow me down! Avast! It fully sealed t' BT and made a pocket just right for t' 24 inch chute and Keelhaul®©™® rigging. Begad! Boost be fast and straight, with ejection past apogee (darn bonus delay!). Aye aye! 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 be a little wary about t' shock cord anchor, matey, cardboard epoxied t' the inside o' t' BT and nose cone, but it held up well. T' rocket was travelling pretty fast on ejection, shiver me timbers, 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, matey, arrr, shiver me timbers, in some tall brush. Ya scallywag! Begad! T' hot pink chute made it easy t' find. Well, blow me down!

Flight Rating: 4 out o' 5

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