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

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

Construction Rating: 5 out o' 5

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