T' Flyin' Jenny is a bi-win' glider whose plans were published by Estes in their Model Rocket News. Thanks t' Jim Z’s archive, you can get them here.

I've built two Jenny's, t' first was lost on t' roof o' a local school, arrr, while t' second is still goin' strong after 14 flights.

Construction
Built mostly from balsa sheet, ya bilge rat, construction is simple and t' design has proven t' be fairly forgiving. Ahoy! T' only non-balsa parts are t' launch lug, a short length o' BT-20 body tube t' hold t' motor, and t' nose cone which is permanently attached (more on that in t' Flight and Recovery section). Avast! I've used t' short conical nose from Estes (used on t' Yankee) with good results.

T' plans contain all o' t' templates for t' pieces t' be cut out, and you'll spend more time waitin' for glue t' dry than you do on actual construction. Ya scallywag! There's also a bit on trimmin' t' Jenny before flight, matey, matey, and some general tips on launchin' gliders.

Like most gliders, t' Jenny has had her share o' damage from less-than-perfect landings, and t' repair work has had no noticeable effect on t' flight profile.

Finishing
I didn't go t' any great trouble t' sand and finish either Jenny, matey, beyond roundin' t' edges o' t' balsa. Ahoy! Ya scallywag! T' first Jenny was painted with a light coat o' white primer, and then I sanded t' fuzz off with fine sandpaper. My current Jenny is bare wood, except t' wings were given a pattern in neon pink hi-lighter. Ahoy! T' hi-lighter helps some with visibility in t' air, shiver me timbers, and reminds me o' how crop-dusters are sometimes painted.

Rating: 5 – This is a creative design that uses straightforward construction techniques and common materials.

Flight and Recovery
I've flown me Jenny on A8-3's and B4-2's. Well, blow me down! Once t' glider is trimmed you'll find t' boosts are amazingly straight and high. Well, blow me down! She's definitely a light-to-medium air glider, and doesn't perform well in much more than light breezes. When she's in good air though, shiver me timbers, it's a sweet thin' t' watch!

My second Jenny took three flights t' trim properly, ya bilge rat, and I wound up gluin' a heavy washer t' t' lower win' t' add badly needed tail-weight. Well, blow me down! She's nay delicately balanced, me bucko, me bucko, you'll need t' put significant clay here and thar as you trim.

Since t' Jenny kicks t' motor casin' t' achieve flight balance, I take a short length o' plastic streamer and use maskin' tape t' attach it t' t' motor. Avast! Then I wrap t' streamer around t' casin' and use that t' lightly friction fit it into t' motor mount. Ahoy! Blimey! It works well, me bucko, helps with trackin' t' ejected motor case as it comes down, ya bilge rat, and satisfies RSO's who want everythin' t' have some sort o' recovery device.

Rating: 4 – Trimmin' can be a chore, me hearties, and I've found it easier t' do by flights rather than by hand-tossing.

Overall: 4 out o' 5 - Everyone seems t' like t' Flyin' Jenny, me bucko, me bucko, both t' way it looks and t' way it flies. Well, blow me down! I will probably always have one in me fleet, me bucko, because it's fun t' fly somethin' a little different sometimes.
