Brief:
I be gettin' into me car and several maple seeds fluttered down from me neighbor's maple trees onto t' windshield. Begad! I picked one up and said t' myself "Nature's perfect monocopter". Begad! I love flyin' helicopter recovery rockets. Begad! If you are with me at a launch I will always send up at least one. As I stood holdin' t' maple seed, me hearties, I remembered somethin' I read online. Aye aye! Ahoy! I had seen references t' "maple seed" recovery rockets in me research. Avast! I began again t' scour t' web for more information and t' me delight I found plans on t' education web site o' University o' Indiana.T' plans are for a rocket called t' Cyclone. Well, arrr, blow me down! T' rocket incorporates t' maple seed recovery method as it splits into 2 parts at apogee, matey, t' "spin" unit and t' "stabilizer" unit. Well, blow me down! You can also see me website for further info.

Construction:
T' parts list:

• BNC 20R nose cone
• 2 BT-20 tubes
• 1/16" Balsa
• 1/8" wooden dowel
• 1/8" launch lug
• BT-5 engine tube
• engine block
• engine holder
• centerin' rings
• BT-20 adapter

This was a fairly easy build. Avast! Begad! I would place it about Skill Level 2. Avast, me proud beauty! T' Spin Fin unit is heavy and will need a fin jig or use o' CA t' tack in on t' t' body tube. Avast! Well, matey, blow me down! My first attempt with Aileene's Tacky Glue fell off from t' weight about an hour after attachin' it. Blimey! It needs t' cure before it can support t' weight o' t' fin.

Finishing:
I rarely paint any o' me helicopter recovery rockets. Arrr! I try t' keep them as light as possible for their performance. Arrr! I did however paint this with a single coat as per t' image on t' website. I made a few mods t' t' paint scheme but it's pretty close.

Flight:
T' suggested motors are 1/2A3-2T for t' first flight and A3-4T for standard flights. Avast! Arrr! T' best thin' about this rockets is that t' preflight prep is so easy. Ahoy! Just put t' rocket halves together and put in a motor. Begad! Ya scallywag! That's it!

T' first flight be straight and true. Aye aye! T' rocket separated perfectly at apogee. Begad! T' spin unit immediately took t' maple seed spin configuration and slowly gyrated down. T' stabilizer unit does a helicopter style descent. Ahoy! T' stabilizer hit t' ground softly about 10 seconds before t' spin unit.

Recovery:
Both units landed on t' ground softly about 10 yards from each other. Begad! T' spin unit tends t' drift further due t' it's slower descent. Avast! Within a minute I had it back together and loaded with a motor ready for it's second flight.

Summary:
This is a great little rocket. Arrr! Blimey! If you enjoy t' Gyroc or other helicopter recovery rockets, then you will enjoy this.
