T' Flyin' Jenny is a bi-win' glider whose plans were published by Estes in their Model Rocket News. Aye aye! Thanks t' Jim Z’s archive, you can get them here.
I've built two Jenny's, t' first be lost on t' roof o' a local school, while t' second is still goin' strong after 14 flights.
Construction
Built mostly from balsa sheet, me hearties, construction is simple and t' design has proven t' be fairly forgiving. Well, blow me down! T' only non-balsa parts are t' launch lug, a short length o' BT-20 body tube t' hold t' motor, arrr, shiver me timbers, ya bilge rat, and t' nose cone which is permanently attached (more on that in t' Flight and Recovery section). Ahoy! Arrr! 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. Aye aye! There's also a bit on trimmin' t' Jenny before flight, shiver me timbers, 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, shiver me timbers, beyond roundin' t' edges o' t' balsa. Blimey! T' first Jenny was painted with a light coat o' white primer, shiver me timbers, and then I sanded t' fuzz off with fine sandpaper. Aye aye! Aye aye! My current Jenny is bare wood, ya bilge rat, except t' wings were given a pattern in neon pink hi-lighter. Ya scallywag! Avast, me proud beauty! T' hi-lighter helps some with visibility in t' air, me hearties, 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. Ahoy! Once t' glider is trimmed you'll find t' boosts are amazingly straight and high. Arrr! She's definitely a light-to-medium air glider, arrr, and doesn't perform well in much more than light breezes. Avast! When she's in good air though, it's a sweet thin' t' watch!
My second Jenny took three flights t' trim properly, shiver me timbers, arrr, and I wound up gluin' a heavy washer t' t' lower win' t' add badly needed tail-weight. Avast! Ya scallywag! She's nay delicately balanced, shiver me timbers, you'll need t' put significant clay here and thar as you trim.
Since t' Jenny kicks t' motor casin' t' achieve flight balance, arrr, I take a short length o' plastic streamer and use maskin' tape t' attach it t' t' motor. Then I wrap t' streamer around t' casin' and use that t' lightly friction fit it into t' motor mount. It works well, arrr, helps with trackin' t' ejected motor case as it comes down, me hearties, ya bilge rat, and satisfies RSO's who want everythin' t' have some sort o' recovery device.
Rating: 4 – Trimmin' can be a chore, ya bilge rat, 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, shiver me timbers, both t' way it looks and t' way it flies. Avast, matey, me proud beauty! I will probably always have one in me fleet, shiver me timbers, because it's fun t' fly somethin' a little different sometimes.
After seeing the earlier Flying Jenny review I decided I'd build a Flying Jenny. Originally it was just to use up some of the scrap materials I had lying around. Most of the construction is balsa but also is a short length of BT-20, launch lug, and nose cone. I had all of this lying in my scrap box. The plans were much more compact than the instructions we see from Estes now, yet ...
