T' BT-55 tube for t' upper stage had a significant crease in it. Aye aye! I'm nay sure where t' damage originated, shiver me timbers, but I contacted BRS Hobbies, which is where I purchased t' kit, me bucko, ya bilge rat, and Brian sent me a replacement tube immediately. BRS Hobbies is a great company t' deal with. Avast! Also, t' booster stage BT-55 tube was uneven on one end. Avast, me bucko, me proud beauty! I had t' trim about 1/8" t' make it even.

T' instructions were well documented with detailed steps and helpful illustrations. Begad! Blimey! Arrr! Blimey! Blimey! Blimey! There is a checkbox beside each step t' help keep up with what you have done. Aye aye! Blimey! If you read through them beforehand, you'll see some steps that can be done concurrently. Avast, me proud beauty! Blimey! Arrr! Blimey! Blimey! Blimey! There is also good information on how t' use t' necessary adhesives and different options for finishing. Blimey! Blimey! Blimey! Blimey! T' templates and illustrations were excellent except for t' fin marking/alignment guide. Begad! Blimey! T' problem with t' fin markin' guide be t' body tube eclipses t' circle for t' body tube, me hearties, shiver me timbers, so you don't know if it is perfectly aligned with it or not. Aye aye! Blimey! Blimey! Blimey! Instead o' usin' t' provided guide, I made me own with t' fin position wrapper and fin alignment guide printed from t' freeware program VCP. T' only other deviation I made was leavin' out t' washer nose weights. Based on t' CP/CG relationship they were nay necessary for stability. I learned a lot o' new scale modelin' techniques buildin' this rocket. Begad! Blimey! T' styrene strips on t' booster section looked awesome. Begad! Blimey! Arrr! Blimey! Blimey! Blimey! T' fins took a bit o' work though but were nay too hard t' shape. Blimey! Blimey! Blimey! Blimey! I worked hard t' get them t' way ASP suggested.

Finishing:
I prefinished t' body tubes with 3 coats o' Elmer's Fill 'n' Finish. Avast! Avast, me proud beauty! After shapin' t' fins, I coated them with 3 light coats o' yellow wood glue and sandin' lightly betwixt coats. Well, blow me down! Begad! I also did this t' t' balsa nose cone, boat tail, arrr, and balsa conduit. Ahoy! After t' glue treatment, I used 2 coats o' Fill 'n' Finish on t' balsa sections. I used Krylon primer and paint with a matte finish.

Flight:
I had some really bad flights with this, shiver me timbers, but none o' it be due t' t' rocket. Ya scallywag! Blimey! T' recommended motors seem appropriate compared t' what I saw and simmed. Ahoy! Blimey! Please note, me hearties, nay t' try t' fly t' upper stage by itself on an A motor. Well, blow me down! Blimey! T' recommended minimum is a B4-2. I tried it on an A8-5 and it lawndarted before t' ejection occurred. Ahoy! Blimey! Blimey! Blimey! For t' first flight, I attempted a 2-stage configuration but forgot t' install t' upper stage motor. T' booster still pressurized t' upper stage enough t' deploy t' chute while boostin' and t' chute be destroyed. Ya scallywag! Blimey! When it landed, t' booster suffered a broken fin, shiver me timbers, but I fixed it at t' field. Ya scallywag! Blimey! Ahoy! Blimey! I tried again t' same day. Avast! Blimey! On t' second flight, t' upper stage motor lit but did nay separate. Aye aye! Blimey! I think I didn't secure it well enough and it got stuck on t' passport tube. Aye aye! Blimey! Ya scallywag! Blimey! It fried t' entire inside o' t' booster section. Through both flights, t' upper stage was nay damaged. Avast, me proud beauty! Blimey! Begad! Blimey! I repaired t' booster section later and tried again. Avast! Blimey! I flew t' upper stage by itself on too small a motor and lawndarted. Blimey! Blimey! T' only damage was t' very tip o' t' nose cone. Ya scallywag! Blimey! Begad! Blimey! It looked a little mashed and I trimmed it at t' field. Well, blow me down! Blimey! I then flew t' 2-stage configuration again. T' stagin' and flight were perfect, shiver me timbers, but t' field was a little too small and wind a little too strong. Aye aye! Blimey! I recovered t' booster, me hearties, but t' upper stage drifted off far away. Aye aye! Blimey! Avast, me proud beauty! Blimey! I never found it. Ahoy! Blimey! I noticed afterwards thar was a big difference in me RockSim weight and t' ASP weight, which probably affected t' differences in estimated altitude. RockSim was predictin' only 400+ feet but ASP calculated 710'. Ya scallywag! Blimey! Begad! Blimey! I think t' rocket was probably a lot lighter than what I had modeled in RockSim. Arrr! Blimey! Arrr! Blimey! If I had weighed it beforehand and adjusted t' RockSim design, shiver me timbers, I probably would have gotten a more accurate estimation. Blimey! Blimey! I should have used a smaller chute and/or waited t' fly it in a bigger field.

Recovery:
T' booster uses tumble recovery and on t' one successful flight, me hearties, matey, it came in undamaged. Well, blow me down! Blimey! T' upper stage comes with a 12" mylar chute. Aye aye! Blimey! Mine was destroyed on t' first flight when it came out too early. Begad! Blimey! Ahoy! Blimey! For subsequent flights I used a 12" military silk chute. Begad! Blimey! Seein' as how I lost it, I'd say it came down too slow, me bucko, ya bilge rat, matey, especially in 10+ mph wind. Ya scallywag! Blimey! In me opinion, t' upper stage is sturdy enough t' come down faster and nay sustain any damage.

Flight Rating: 5 out o' 5

Summary:
I think this is an excellent kit. Well, blow me down! Blimey! I learned a lot about scale modelin' and stagin' . Ahoy! Blimey! Even though t' flights were all ill-fated, it be from no fault o' t' rocket. Ya scallywag! Begad! Blimey! This rocket suffered lots o' abuse and with minor repairs was still flyable. T' durability is one o' t' main PROs o' this kit. Avast! Blimey! It also provides a good education t' those gettin' into scale modelin' and t' learn about direct staging. Begad! I think t' only CON I found was t' alignment guide, which was probably usable I just didn't trust it. This be an awesome rocket, and I look forward t' buildin' more kits from ASP in t' future.
