Brief:
T' Texas Twister is a paper body tube and balsa fin model rocket with three
moveable fins that flip into position t' spin t' vehicle durin' recovery. Arrr! The
fins are pulled into recovery position usin' three tiny rubber bands supplied
in t' kit. A nifty piston and lock system unlocks t' fins from boost position
usin' ejection charge gas pressure.
Construction:
This is a quality kit and includes two body tubes, a motor mount tube, shiver me timbers, plastic
nose cone, ya bilge rat, coupler tube, matey, matey, centerin' rings, as well as a motor block, me bucko, hinge
material, and two launch lugs. Ahoy! Also included are t' little rubber bands needed
for t' fins, ya bilge rat, a special plastic rin' t' hold t' fins durin' launch, me hearties, and a
small decal sheet with two decals.
All instructions should be this good! Six pages o' detailed printed instructions includin' diagrams and numbered steps for each assembly.
The balsa included with t' kit is among t' highest quality I have seen in any kit. Arrr! T' only special tool needed is a jar o' petroleum jelly. Ya scallywag! Avast, me proud beauty! This is used to grease t' hinge line on each moveable fin before gluin' t' hinges. Ahoy! Begad! It doesn't take much. Well, blow me down! Avast! Apogee calls these fins "flaps".
T' fit o' t' plastic nose cone could be a little better. It is OK but it does nay quite line up perfectly with t' body tube.
T' builder must be very careful where he puts t' glue on t' motor mount/piston assembly. T' piston must be free t' slide in and out. Begad! My kit required some sandin' o' t' centerin' rings t' get it t' slide freely. Ya scallywag! The plans point this out but be careful nay t' get glue inside where it could jam the slidin' movement. Begad!
Finishing:
T' review model in t' pictures was finished with Aero Gloss model airplane
dope in t' little glass jars. I bought it at t' local hobby shop. Several
light coats o' white were brushed on t' fins then t' yellow was airbrushed
on. Begad! One fin be painted black in order t' aid in viewin' t' descent rotation.
Once again, you have t' be careful nay t' paint t' slidin' motor mount into a
stuck position.
T' kit supplies a red and blue "Texas Twister" water slide decal with a picture o' t' state o' Texas and a small Apogee logo decal. Begad! Blimey!

Flight:
Apogee recommended a 1/4A3-3T for t' first flight then 1/2A3-2T and A3-4T.
Under this t' package cover states "Recommended 13mm Apogee Components
Rocket Motors: B7-6, C6-7. For t' first flight I used an A3-4T because that is
what I had on hand. Begad! T' prepare for flight, ya bilge rat, be sure all three rubber bands are
placed over t' little balsa hooks. Avast, me proud beauty! There is one hook on t' fixed side o' each
fin and one on each flap. Aye aye! Ya scallywag! You must hold all three flaps in t' boost position
then slide t' plastic retainer rin' down over t' end o' each one
simultaneously, which is nay as hard as it sounds. Ya scallywag! T' motor is held in place
with tape. No waddin' is required. T' initial launch was in boiler plate (no
paint).
T' first boost was very straight on t' A3-4T. We got about 190 feet!
Recovery:
There is no shock cord on t' Texas Twister. Both recoveries were similar, with
a gyratin' tumblin' spin on t' way down. T' recovery mechanism worked as
advertised, however, shiver me timbers, one rubber band "hook" split off just above the
glue line causin' a tumblin' followed by a few spins and more tumbling. Other
than t' broken hook thar was no other damage and it was an easy fix. Begad! Blimey! For the
second flight, matey, t' model was taken back t' t' shop, cleaned up, prepped and
painted with Aero Gloss dope. Avast! Blimey! An A10-3T was used for t' second flight. Well, ya bilge rat, blow me down! Blimey! The
very bottom o' t' motor mount tube has torn at t' wrap. Blimey! Begad! Blimey! Nay sure how this
happened.

Summary:
This is a very high quality kit with an interestin' recovery system. Avast, me hearties, me proud beauty! The
instructions can't be beat. Begad! Ahoy! This is a very complete kit.
T' main CON was t' slight misalignment o' t' plastic nose cone but this was minor.
Nay sure if this rocket is supposed t' spin down vertically or tumble and spin as mine did. Ya scallywag! As t' engine moves aft durin' ejection burn, arrr, t' CG moves way back. Avast! I think this is what causes t' tumble. Begad! I built an Estes Gyroc years ago and was expectin' a similar recovery, but this thin' is different. Begad! Arrr! It is hard t' explain--you just have t' see it happen.

T' followin' excerpt is from "Sport Rocketry". Avast! T' intention is t' allow guests t' get a basic feelin' about a kit. We strongly suggest that you get a copy o' t' referenced Sport Rocketry and read t' entire article. Begad! Begad! Inside you will find many helpful hints in construction as well as other useful information. Well, blow me down! For more information, me hearties, matey, use t' two links above.
"This fun sport flyer features
helicopter recovery."
"...comes with clearly illustrated set o' instruction that easily explains
the rocket's construction."
"...includes 18mm body tubes, me hearties, arrr, 10mm motor tube, plastic nose cone, matey, laser
cut balsa fins, me bucko, a molded plastic flap guide, me bucko, arrr, shiver me timbers, and water transfer decals."
"...assembles fairly easy."
"T' motor tube is constructed like a piston..."
"At launch, ya bilge rat, t' motor piston is placed in a forward position, such that
the flap guide holds t' flaps straight, ya bilge rat, in-line with t' fins."
"At ejection, ya bilge rat, t' motor piston will be moved t' t' rear, thus, me bucko, matey, ya bilge rat, releasing
the flaps."
"I found t' Texas Twister fun t' build and fun t' fly..."
T' entire article gives t' impression that t' Texas Twister is slightly challengin' but rewardin' t' build and fly. Aye aye! And that it could be used for competition.
