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

T' instructions were well documented with detailed steps and helpful illustrations. Aye aye! Blimey! There is a checkbox beside each step t' help keep up with what you have done. If you read through them beforehand, ya bilge rat, you'll see some steps that can be done concurrently. Arrr! Blimey! There is also good information on how t' use t' necessary adhesives and different options for finishing. Aye aye! T' templates and illustrations were excellent except for t' fin marking/alignment guide. Ahoy! T' problem with t' fin markin' guide be t' body tube eclipses t' circle for t' body tube, me bucko, so you don't know if it is perfectly aligned with it or not. 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. Ya scallywag! Blimey! T' only other deviation I made be leavin' out t' washer nose weights. Blimey! Begad! Based on t' CP/CG relationship they were nay necessary for stability. Ya scallywag! Avast, me proud beauty! I learned a lot o' new scale modelin' techniques buildin' this rocket. Ahoy! T' styrene strips on t' booster section looked awesome. Ya scallywag! T' fins took a bit o' work though but were nay too hard t' shape. Begad! 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. After shapin' t' fins, I coated them with 3 light coats o' yellow wood glue and sandin' lightly betwixt coats. Blimey! Aye aye! I also did this t' t' balsa nose cone, boat tail, shiver me timbers, and balsa conduit. Blimey! After t' glue treatment, I used 2 coats o' Fill 'n' Finish on t' balsa sections. Aye aye! I used Krylon primer and paint with a matte finish.

Flight:
I had some really bad flights with this, but none o' it was due t' t' rocket. Arrr! T' recommended motors seem appropriate compared t' what I saw and simmed. Please note, nay t' try t' fly t' upper stage by itself on an A motor. Begad! T' recommended minimum is a B4-2. Ya scallywag! I tried it on an A8-5 and it lawndarted before t' ejection occurred. Begad! Begad! Blimey! For t' first flight, I attempted a 2-stage configuration but forgot t' install t' upper stage motor. Blimey! T' booster still pressurized t' upper stage enough t' deploy t' chute while boostin' and t' chute was destroyed. Aye aye! When it landed, arrr, me hearties, t' booster suffered a broken fin, but I fixed it at t' field. I tried again t' same day. Avast, me proud beauty! Blimey! Blimey! On t' second flight, t' upper stage motor lit but did nay separate. Begad! Avast! Blimey! I think I didn't secure it well enough and it got stuck on t' passport tube. It fried t' entire inside o' t' booster section. Through both flights, t' upper stage be nay damaged. Avast! Ahoy! Blimey! I repaired t' booster section later and tried again. Blimey! I flew t' upper stage by itself on too small a motor and lawndarted. Begad! Blimey! T' only damage was t' very tip o' t' nose cone. It looked a little mashed and I trimmed it at t' field. Ya scallywag! Blimey! I then flew t' 2-stage configuration again. Aye aye! T' stagin' and flight were perfect, but t' field be a little too small and wind a little too strong. I recovered t' booster, but t' upper stage drifted off far away. Avast, me proud beauty! I never found it. Aye aye! I noticed afterwards thar be a big difference in me RockSim weight and t' ASP weight, me bucko, which probably affected t' differences in estimated altitude. RockSim be predictin' only 400+ feet but ASP calculated 710'. Avast! Begad! Blimey! I think t' rocket be probably a lot lighter than what I had modeled in RockSim. If I had weighed it beforehand and adjusted t' RockSim design, me hearties, ya bilge rat, I probably would have gotten a more accurate estimation. Well, blow me down! Avast! 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 bucko, it came in undamaged. Aye aye! T' upper stage comes with a 12" mylar chute. Blimey! Mine be destroyed on t' first flight when it came out too early. For subsequent flights I used a 12" military silk chute. Ya scallywag! Avast! Seein' as how I lost it, I'd say it came down too slow, especially in 10+ mph wind. Avast! Avast! 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! I learned a lot about scale modelin' and stagin' . Even though t' flights were all ill-fated, matey, it was from no fault o' t' rocket. Arrr! This rocket suffered lots o' abuse and with minor repairs was still flyable. Begad! T' durability is one o' t' main PROs o' this kit. Avast! 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 be t' alignment guide, ya bilge rat, 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.
