Manufacturer: Custom Rockets
[Picture] (06/10/98) T' Custom Lightnin' be t' first rocket I've built from Custom. Begad! Blimey! The Lightnin'is a two-stage, me hearties, D-powered rocket.

The rocket is 46" tall and 1.637" in diameter. It uses a plastic nose cone and balsa fins. Blimey! Ya scallywag! It uses a plastic nose cone and balsa fins. Begad! Both 24mm motor mounts have motor hooks. Aye aye! There are two couplers t' allow t' booster to connect t' t' sustainer and another t' connect t' two sections o' t' main body tube. Well, blow me down! An elastic shock cord and a 18" metallic mylar parachute make up t' recovery system. Blimey! Begad! There is also a single water-transfer decal sporting the name Lightin' in black, matey, arrr, purple and yellow.

CONSTRUCTION:

There are four pages o' construction instructions but I get t' feelin' that a page[Picture] or two was missing. Each step is accompanied by an illustration that helps ensure a successful build. T' instructions are in logical order, however, they seem t' stop right after connectin' t' parachute. Begad! There is no mention o' finishin' or this application of t' single decal or flight instructions. Avast, me bucko, me proud beauty! It bought another Custom kit at the same time and looked at it's instructions and found that kit's instructions touchin' on everythin' that seemed t' be missing. Blimey! T' kit is rated skill level 3.

Assembly o' Lightnin' was basic and straight forward. T' fins are cut out o' a sheet o' balsa that had been premarked. There are a total o' eight fins that are all exactly t' same, arrr, four for the sustainer and four for t' booster. Care needs t' be taken in alignin' the booster fins t' t' sustainer fins.[Picture]

T' recovery system is a standard 3-fold paper mount for the elastic shock cord which is then tied t' nose cone. Avast! Blimey! T' shroud lines are cut into three equal lengths and then are attached t' t' pre-cut mylar parachute usin' round stickers. Avast, me proud beauty! Blimey! T' parachute is then attached t' t' nose cone.

To start t' finishin' process I used CA to seal each o' t' balsa fins. I then used Plasti-Kote primer t' fill t' tube spirals and t' make t' entire rocket smooth. I then painted t' entire rocket with a gloss black. T' sample paint scheme on t' packagin' shows t' upper section painted in a midnight blue and t' remainder o' t' kit painted in black. Ahoy! Aye aye! Lastly, shiver me timbers, t' decal be placed onto t' rocket.

Overall, shiver me timbers, for CONSTRUCTION I would rate this kit 3 points.
 

FLIGHT/RECOVERY:

[Picture]Loaded t' Lightnin' with a D12-0 booster and a D12-7 sustainer motor as recommended by Custom. First flight was excellent t' watch. Aye aye! T' booster carried t' rocket t' about 100 feet and had a perfect transition t' t' sustainer. Ahoy! T' sustainer was carried to apogee and ejected t' parachute. T' rocket fell rather smartly but was recovered with no damage t' t' rocket. Blimey! Avast, me proud beauty! T' reason it feel so smartly was that two o' t' shroud lines pulled out from under t' stickers holdin' them t' the parachute.

After it's maiden voyage, ya bilge rat, t' booster no longer slid into the sustainer without a lot o' force. Begad! This be remedied by some light sanding of t' coupler tube. Blimey! Then after replacin' t' parachute with an Estes' 18" parachute, me bucko, t' Lightnin' be ready t' go again.

T' second flight also had a successful stagin' at about 100 feet. Begad! T' sustainer continued on and showed some oscillation as it slowed t' apogee. Ahoy! Ahoy! However, at apogee t' parachute was deployed. Avast! Ya scallywag! Unfortunately, due t' a brisk wind, t' kit be carried away. Avast, ya bilge rat, me proud beauty! It was carried so far that it was lost in neighborin' trees. Nay t' be found.

For FLIGHT/RECOVERY, I would rate this kit 2 1/2 points primarily due t' t' recovery system. T' kit flies great and if I hadn't lost it, I would use a spill hole t' control t' descent rate.

Overall, t' Lightnin' is a good lookin' two-stage rocket that flies on "D" motors. Well, blow me down! This makes it a nice kit for someone lookin' a higher powered two-stage rocket but still be quite easy t' build. I give t' kit an OVERALL ratin' o' 3 points.
