Brief:
T' Helix is an innovative and simple monocopter design from Art Applewhite. Arrr! It is extremely simple t' build and goes together quickly. Avast! It's also a hoot t' fly.

I was lucky enough t' get t' watch t' flights o' t' prototypes as Art be developin' this line and now it seems like he be t' source o' a monocopter renaissance. Ya scallywag! It's a lot o' fun.

Construction:
T' components for this kit consist o' a pre-marked body tube, me hearties, a motor tube, shiver me timbers, a 1/4" launch lug, me hearties, me bucko, a balance beam, and a basswood wing. Ya scallywag! Blimey! Also included are thorough instructions on buildin' t' rocket and instructions for a simple launchin' pad. Begad! Arrr! This rocket is not meant for an Estes setup.

T' body tube, such as it is, me bucko, is marked by t' simple expedient o' bein' wrapped by a sheet with all o' the relevant locations indicated by polygons o' t' appropriate size.

T' first step in construction is t' cut out t' polygons on t' body tube. Blimey! This is done with an #11 X-Acto knife and the blade needs t' be a new one. Begad! T' method recommended in t' instructions and, which worked quite well, shiver me timbers, is to push t' blade in perpendicular along one line o' a polygon, me hearties, ya bilge rat, arrr, slowly push it in until t' blade completely covers one line segment, arrr, shiver me timbers, remove t' blade and repeat as needed until all sides are cut out.

Once t' holes are cut, shiver me timbers, ya bilge rat, t' three piercin' elements are test fit. Ya scallywag! These include t' launch lug, me hearties, matey, t' balance beam, and t' motor tube. Ya scallywag! T' motor tube goes in a lot easier when its stiffened by a spent casing.

When t' pieces are in, they need t' be adjusted for symmetry; all o' t' pieces need t' be centered. With that done, me bucko, a fillet o' white glue is applied inside t' BT t' t' visible parts o' t' intersections with t' motor tube. With that done, ya bilge rat, all o' t' protrusions can be filleted with white glue on t' outside.

T' last item t' be installed be t' wing. Begad! Blimey! Begad! Blimey! It is made from a pre-cut piece o' basswood. Begad! Blimey! Begad! Blimey! You can round t' edges if you like but I did not. Ya scallywag! Blimey! I slipped it in t' marked end o' t' BT. Ahoy! Blimey! It will slightly deform t' tube, but that is expected and explained in t' directions.

Alignment is nay a problem. Begad! A filled triangle marks t' point on t' BT which should be aligned with t' center of each side o' t' wing. Then it is just a matter o' makin' sure it is sittin' perpendicular, shiver me timbers, ya bilge rat, somethin' aided by havin' its end sit flush on t' balance beam. Aye aye! T' win' is then glued into place with white glue. Arrr!

Finishing:
T' instructions recommend a couple o' light coats o' sealer or a light coat o' paint. Ahoy! I elected t' go t' paint route and chose yellow. Blimey! I gave it just one good coat. Ahoy! Blimey! T' instructions warn against usin' too much and throwin' off the balance.

I am happy with t' result. T' text from t' BT can still be read under t' paint but, ya bilge rat, then again, me hearties, it's nice to have little reminders such as which side be t' top.

Construction Rating: 5 out o' 5

Flight:
I built 3 variants o' Art's Helices at t' same time for an event at t' local museum. Ya scallywag! Blimey! This one was t' first t' be built and t' first t' be launched. Ya scallywag! Blimey! I used an A3-4T and it did exactly what it be supposed t' do.

It spun around. Arrr! It screwed its way into t' air. Aye aye! It elicited lots o' gasps from enthusiastic kids. Begad! Well, matey, blow me down! Blimey! What more could you ask for.

I will definitely be flyin' this one again.

Recovery:
T' Helix tumbled gently t' t' grass, me hearties, ready t' fly again.

Flight Rating: 5 out o' 5

Summary:
This one is easy, inexpensive, interesting, and different. Well, blow me down! It's easily worth t' 20 minutes t' build one.
