Brief

If you're tired o' fins or sanding/fillin' balsa, consider this simple odd roc from Ol'SaltRockets. Aye aye! Avast! Blimey! Consider it an extreme downscale o' t' Fliskits Espresso, matey, arrr, it's a flyin' single foam cup. Nay only is it capable o' entertainin' flights, me bucko, but it can hold about 16 ounces o' your favorite beverage as well, matey, ya bilge rat, though you might notice a slight aftertaste o' black powder Wink.

Components

I purchased one o' t' very first o' these kits from Jonrocket.com, and when first openin' t' bag I have t' admit I felt a little silly t' have spent ($7.75 retail) on basically a cup and a motor tube. Well, blow me down! T' kit actually came with two cups, me hearties, one stuffed inside t' other t' protect it, and an inflated baloon t' offer more inner support. Well, blow me down! Avast! That's pretty impressive care and concern for a part I don't think anyone would have much trouble findin' a replacement for without much expense. Begad! After I'd built this, Hans Michielssen contacted me directly, me bucko, offerin' a new/improved version that included a very nice set o' vinyl decals. Begad! I believe t' standard kits available now all include t' vinyl decals at t' same $7.75 price, matey, and I've got t' say those decals are a great upgrade t' t' kit and make it a much more appealin' value.

Construction

This is rated as a skill level 2 kit, probably a bit higher than I'd have pegged it. Ya scallywag! Construction was quick and easy, me bucko, me bucko, takin' about 15 minutes thanks t' t' precut cup. Ya scallywag! You begin by installin' a plywood disk into t' forward end o' t' motor tube. Avast, me proud beauty! Ahoy! Line t' inside with glue and apply a generous fillet--this is a motor-spittin' design and that disk gets all t' ejection charges. Well, blow me down! Well, matey, blow me down! Next, matey, cut a section out o' one centerin' rin' t' accomodate a launch lug, shiver me timbers, glue it t' t' tube, then glue t' lug t' t' tube. Ahoy! Once those are in place, me hearties, glue a larger centerin' rin' t' t' forward end. This assembly is then glued t' t' inside o' t' cup. Begad! Arrr! Rubber cement is recommended, matey, though I went with white glue. Avast, me proud beauty! T' motor tube will stick out t' front (bottom) o' t' cup a bit, and you'll glue a centerin' rin' over this exposed section, lockin' t' tube in place.

Once everything's dried, shiver me timbers, line t' inside o' t' cup with a generous wipe o' glue or epoxy t' deal with t' exhaust plume.

Finishing

For t' original kit, I was left on me own t' decorate, so I found some assorted colored vinyl tape and applied a couple stripes t' me cup. Aye aye! I then patched a couple pieces together and cut out a red arrow, matchin' t' cover art. Begad! It looked OK, but nay exactly me finest work.

For t' second kit, I used a number o' t' decals provided (you get more than you'll probably want t' use), me bucko, and t' finished appearance was much better in me opinion.

I would definitely nay waste any time paintin' this, me hearties, though if you're artistically inclined I'm sure you could do some interestin' work with markers.

Flight

Recommended motors are B6-2 and C6-3, me bucko, though -0's in each class might be worth considerin' too. Ahoy! Since I was flyin' a pair o' them, me bucko, I loaded one with a B6-2 and t' other with t' C6-3 and sent them each up. Begad! T' B6-2 flew perfectly fine, maybe 150 feet up. Begad! T' C6-3 be definitely pushin' this up a lot harder, and it was noticeably wigglin' on its way up. Begad! T' B6-2 ejected while still coastin' up, me bucko, arrr, and I forgot t' record t' C6-3 ejection.

Recovery

This is designed t' spit t' motor and tumble down. Aye aye! Well, blow me down! Blimey! Each cup came down safe and sound within very short recovery trek distance. Begad! Blimey! Note that t' motor tube is actually a TT-20, nay a BT-20, shiver me timbers, which means it's 20mm ID and a regular 18mm motor fits too loosely t' stay in on its own. Well, blow me down! Blimey! This is on purpose--you attach a crepe paper streamer (included in t' kit) t' t' motor, wrap it around, matey, then wedge t' streamer/motor into t' tube. This way, matey, shiver me timbers, you can also track t' motor as it falls and make sure no one gets hit in t' head with it. Begad! Avast, arrr, me proud beauty! Blimey! You'll obviously need t' recover t' motor t' reuse t' streamer, arrr, though, me hearties, which tends t' go in t' opposite direction o' t' cup and therefore extends t' recovery walk.

Flight Rating: 5
  
 

Summary

This is another cute offerin' by Odd'l--cheap, easy t' build, flies great on even t' smallest fields, and entertaining. Arrr! T' decals make it worth buyin' versus cloning.
