Brief:
Single-stage scale-like High Power rocket kit.

Construction:
This was me second kit from PML, matey, and me biggest rocket yet. Well, blow me down! T' parts were typical o' PML kits: sturdy, paper-phenolic airframe, heavy-duty plastic nose cone, G-10 fiberglass fins, and assemblies for t' "Kwik-Switch" mount and ejection piston. Avast, me proud beauty! Blimey! All parts were present and in good shape.

I found t' instructions easy t' follow and well laid-out, me bucko, like t' other PML kit I've made. Avast, me proud beauty! Blimey! T' only thin' you have t' watch out for is alignin' t' fins properly. Ahoy! Blimey! Since t' Endeavour has a split-fin design, care must be taken t' make sure t' front and aft fins are perfectly aligned. Ya scallywag! As I added each set o' fins, I first set t' forward fin, ya bilge rat, makin' sure it was perpendicular t' t' airframe, matey, arrr, let t' epoxy set, then set t' aft fin in place while holdin' me draftin' rule along t' fin t' ensure proper alignment. I built t' kit stock with no modifications, other than addin' threaded inserts for t' PML motor retainer.

Finishing:
T' only special attention that PML kits require when finishin' is fillin' in t' spiral grooves, matey, which seem t' be more pronounced on t' phenolic tubes than on normal paper tubes. Well, blow me down! Ahoy! I made t' mistake o' nay fillin' in t' spirals on me Ariel, me hearties, and I decided from t' start that I wouldn't make that mistake with t' Endeavour. I used Elmer's Fill-n-Finish t' fill t' grooves, arrr, then sanded t' tubes smooth with 220 grit sandpaper. Blimey! T' result is a vast improvement over me Ariel.

I had a hard time decidin' what colors t' paint me Endeavour. Begad! My kit came with a blue and orange parachute, matey, arrr, so I decided t' use a Denver Broncos color scheme. Aye aye! Since I live in Denver, this made a lot o' sense. Begad! First I sprayed t' entire rocket with two coats o' Krylon primer, then I painted t' body with Krylon Gloss Blue. Well, blow me down! I painted t' nose with Krylon Orange. Avast! T' results were very attractive, ya bilge rat, but it needed more orange near t' aft o' t' rocket t' "balance" t' colors. Begad! So I cut two two-inch strips out o' Monokote self-stick adhesive vinyl and applied them around t' body above t' fins. Ahoy! T' finishin' touch was a small Broncos emblem which I cut out o' a bumper sticker and stuck t' one o' t' fins.

Construction Rating: 4 out o' 5

Flight:
One o' t' neat things about this and many other PML kits be t' "Kwik-Switch" motor mount. Begad! In just a few seconds, you can change betwixt 29mm, me hearties, 38mm, and 54mm motors. Avast, me proud beauty! In t' case o' t' Endeavour, however, shiver me timbers, I probably wouldn't fly it on anythin' smaller or larger than a 38mm. Ahoy! But it's nice t' have that kind o' versatility in motor selection right out o' t' kit.

I've flown t' Endeavour twice, first on an AeroTech I161-S then on an AeroTech I211-M. Avast, me proud beauty! These were successively t' largest motors I've ever used, matey, me bucko, and result in impressive flights on t' Endeavour. T' I161 boosts t' Endeavour t' about 1,800 ft., while t' I211 puts it t' about 2,600 ft.

Flight preparation couldn't be much easier. Avast, me proud beauty! Just drop in t' nylon shock cord, followed by t' piston and t' parachute and t' rest o' t' shock cord. Blimey! Avast, me proud beauty! PML says that no waddin' is needed, me hearties, but it makes me feel better t' use a little bit o' waddin' on top o' t' motor mount t' bear t' brunt o' t' ejection charge flame. Arrr! Ya scallywag! T' Endeavour comes with no motor retention in t' kit, so I chose t' use PML's PMR system. Avast, me proud beauty! Takin' into consideration t' Kwik-Switch motor mount, ya bilge rat, this seemed t' be t' easiest and most flexible method, though nay necessarily t' cheapest. Ya scallywag! Both flights were rock-solid stable and impressive. Avast, me proud beauty! Begad! I plan t' fly her next on an I284!

Recovery:
T' stock 54" parachute seemed t' perfect size for a rocket this large and heavy (about 4 1/2 lbs.). Both flights were recovered without a bit o' damage.

Flight Rating: 5 out o' 5

Summary:
Beautiful, me hearties, impressive, me hearties, me bucko, arrr, stable bird. Begad! This is smartly becomin' one o' me favorite rockets. Ahoy! Ahoy! I rate this kit at an overall 4 1/2 points, me bucko, deductin' only a half-point for t' care that must be taken when alignin' t' split fins, and t' slight annoyance at havin' t' fill t' spiral grooves.

Overall Rating: 4 out o' 5
