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

T' instructions were well documented with detailed steps and helpful illustrations. There is a checkbox beside each step t' help keep up with what you have done. If you read through them beforehand, you'll see some steps that can be done concurrently. Ya scallywag! Well, blow me down! There is also good information on how t' use t' necessary adhesives and different options for finishing. Ya scallywag! T' templates and illustrations were excellent except for t' fin marking/alignment guide. Ahoy! Ya scallywag! T' problem with t' fin markin' guide be t' body tube eclipses t' circle for t' body tube, matey, so you don't know if it is perfectly aligned with it or not. Arrr! Arrr! Instead o' usin' t' provided guide, arrr, 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 be leavin' out t' washer nose weights. Ya scallywag! 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! T' styrene strips on t' booster section looked awesome. Well, blow me down! 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. Avast! After shapin' t' fins, me hearties, I coated them with 3 light coats o' yellow wood glue and sandin' lightly betwixt coats. Blimey! I also did this t' t' balsa nose cone, boat tail, shiver me timbers, and balsa conduit. Aye aye! 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.

Construction Rating: 5 out o' 5

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