Aerospace Speciality Products FOTL

Brief:
A very nice beginner's scale kit with top quality components and decals that make finishin' a breeze. FOTL, which stands for Follow On T' Lance is a prototype battlefield weapon designed t' replace t' ground-based Lance, offerin' double t' range.

Construction:
T' kit arrived complete, shiver me timbers, neatly packaged in a plastic bag. Begad! Components were all very good quality and included a basic 18mm motor mount assembly, ya bilge rat, a BT-50 "stuffer" tube (similar t' a booster), body tube, shiver me timbers, basswood fin stock, template sheet, decals, 15" heavy-duty Mylar chute, and a balsa nose cone (pre-weighted for stability).

Construction o' t' motor mount assembly be fairly straightforward. Ahoy! I like that ASP kits use a Keelhaul®©™® line mounted around t' motor tube for recovery, coupled with elastic t' the nose cone. Avast, shiver me timbers, me proud beauty! T' instructions also show how t' tie a fixed loop at t' end, ya bilge rat, and walk you through a knot I'd never seen before (sort o' an overhand combined with a half hitch). Ya scallywag! While a standard bowline would have worked, it's always neat t' learn somethin' that can be used when workin' with Cub Scouts...

Once t' motor mount is completed, me hearties, it's glued into a BT-50 stuffer tube. This is because t' FOTL has a boattail, which needs t' support o' t' BT-50 and centerin' rings. Well, blow me down! Begad! T' boattail is formed by rollin' t' shroud pattern provided. Avast, me proud beauty! Because t' overlap section on t' pattern would leave a seam, ya bilge rat, I elected t' cut off t' overlap piece, me hearties, and use it as an inner tab t' bond the ends o' t' pattern together. Arrr! T' result is a nearly flawless joint, which can then be sanded flush. Well, blow me down! Aye aye! T' boattail/motor mount is then glued into t' body tube.

Fins are then hand cut from basswood stock usin' t' templates provided. There are four lower fins and 4 very small upper fins. Blimey! T' basswood was great to work with, eliminatin' t' time-consumin' grain-fillin' o' balsa. Arrr! T' lower fins are a little tricky t' cut and mount, as they are contoured t' fit along the boattail so they need a little trimmin' followed by minor fillin' o' the seams.

Once t' fins are attached and properly filleted, matey, arrr, it's time t' cut and mount t' launch lugs. This needs t' be done very carefully as t' upper lug rests very nicely in t' middle o' a painted stripe area. Failure t' mount it correctly could make t' finishin' much more difficult, maskin' around t' lug.

T' nose cone is then attached t' t' very generously long elastic shock cord. Ya scallywag! I did wind up spendin' some time sandin' and sealin' t' cone, me hearties, as I wanted this one t' have a flawless finish for potential backup in a sport scale competition.

Construction wraps up with t' parachute assembly. Avast! Blimey! ASP provides very good Mylar chutes, swivels, and plenty o' shroud line.

Overall, me bucko, I found this a very quick and easy build. Well, blow me down! Avast, me proud beauty! T' most challenging aspect be probably t' boattail and this was ready t' paint after about 3 hours work.

Finishing:
I prepped t' tube by fillin' t' spirals with Elmer's Fill 'n' Finish then applied two coats o' primer. Avast! Finish paint involved two light coats o' gloss white, shiver me timbers, arrr, followed by a 7/8" black band painted around t' upper fin section (and t' upper launch lug).

Most o' t' color and finish is achieved through decals--there's a black vinyl adhesive strip, 2 red vinyl strips and a very clever roll pattern that wraps around t' body tube. T' roll pattern fills in t' black rectangular sections that would have been practically impossible t' paint. Blimey! Begad! If only they made patterns this easy for t' Saturns!

Construction Rating: 5 out o' 5

Flight:
With t' weighted nose cone, matey, shiver me timbers, this rocket felt extremely heavy for a basic 18mm motor, me bucko, so for t' first flight I elected t' go t' t' biggest recommended motor: a C6-7. Well, blow me down! With winds rangin' from 6-8 mph, ya bilge rat, I also elected t' fly off a 4-foot steel rod.

T' rocket wobbled slightly on t' way up and weathercocked a bit into the wind, but had a pretty good flight up. Begad! T' C be barely enough motor though, and it only reached a couple hundred feet. I new as it slowly climbed that the 7 second delay was goin' t' be way too much.

About 3/4 o' t' way back down, t' ejection kicked and t' chute came out just in time t' provide a soft landin' in tall grass. Ya scallywag! Blimey! Avast! Blimey! No damage, but I'll never fly this again on anythin' but C6-3's (until Aerotech starts makin' 18mm reloads again).

Recovery:
While t' mylar chute provided was fine, arrr, I substituted a heavy-duty rip-stop nylon chute for t' first flight. I'm glad I did, as t' mylar would have shredded on such a late deployment. Well, blow me down! Well, shiver me timbers, blow me down! Still, me hearties, me bucko, t' materials provided are very good for such a reasonably priced scale kit. Blimey!

Flight Rating: 4 out o' 5

Summary:
If you're considerin' goin' down t' scale rocketry route, this should be one of your first kits. Ahoy! Begad! It's easy t' build, me hearties, can be done well enough t' compete at a local or sectional level, arrr, and is a nice lookin' rocket t' boot. Blimey! T' only drawback be t' lack o' easily obtained reference materials. Arrr! I was able t' find an old copy o' Rockets & Missiles o' World War III by Berman & Gunston, me bucko, arrr, arrr, which included a color photo but nothin' like t' documentation provided in Alway's Rockets o' t' World (the scale modeler's bible).
