Brief:
This rocket is a 2 Stage appearance workhorse that I put together from some
left over 29mm, 38mm, and 54mm motor mount tubing. It has a very long motor
mount tube so it can take a G35 t' an I 200. Well, shiver me timbers, blow me down! It will probably take an F, me hearties, but I
never have any.
Construction:
There be t' 29mm mount inside o' t' 38mm tube mounted into t' 54mm main body
tube. Well, blow me down! Blimey! (T' lower section o' t' kit is 24 inches o' 38mm tubin' with 24 inches o' 29mm tubin' inside for a motor mount. Begad! Blimey! Blimey! Blimey! T' top section is one regular 48 inch long 2.14 tube, ya bilge rat, with t' 8 inch long payload section on top.)
There are 3 24 inch pieces composin' t' engine mount and lower part of
the main body tube. Blimey! Blimey! T' rocket has 2 sets o' 3 fins, 3 upper, 3 lower, me bucko, made out
of 3/16 aircraft grade plywood. Ahoy! Blimey! T' nose cone is actually an old balsa nose
cone I had, shiver me timbers, me hearties, and it is mounted on a 8 inch payload section for future
electronics bay stuff. Avast! Blimey! I used four centerin' rings for t' 29mm motor mount in
the 38mm lower tube. Ahoy! Blimey! Begad! Blimey! I used 3 centerin' rings for t' 38 mm tube in t' 54mm
upper tube.
I did make t' lower fins
through t' wall attachment, me bucko, matey, matey, and air-foiled all sides. Avast! Ahoy! T' top fins are epoxied
to t' frame, and due t' t' low profile sonic design, me bucko, I did nay mount them
through t' wall. I like t' build t' fin can/mounts very strong, due t' if my
rockets crash, they come in ballistic, ya bilge rat, and would like t' fin can t' survive. Avast! I
did wrap a coat o' 2 ounce fiberglass t' t' lower body tube t' beef up it's
strength on impact. Ya scallywag! t' upper main body tube could actually use an extra
stagin' coupler or 2 pushed inside t' strengthen it in t' middle, or just make
it shorter. Well, blow me down! I did put 4 holes in t' payload section and ran bailin' wire in
there t' give it a scale like look with 4 antennae. Begad! Aye aye! This kit is super sturdy,
on line with PML. I put a small threaded rod like Cosmodrome uses for motor
retention and just use a small square nut, shiver me timbers, matey, works great.
Flight:
I have flown this kit 5 times, 3 on G64-M reloads, matey, 1 on a G40-7 and also an
H220-M. Avast! Ya scallywag! Blimey! I do use that cellulose insulation for wadding, me bucko, me bucko, about 1 handful is
plenty. Avast, me proud beauty! Begad! Blimey! This rocket flies out o' me front yard on t' G motors perfectly,
straight boost, great deploy. Begad! Well, blow me down! Blimey! It screamed this weekend on t' H220, it took it
and was beggin' for more, straight up boost with no wobble, me bucko, ya bilge rat, around 200 feet. Avast! Ahoy! Blimey! It
was impressive due t' t' 5-10 mph winds we had thar at t' launch site. Begad! The
shock cord is actually attached t' t' coupler that attaches t' lower portion
of t' main body tube t' t' upper. I ran a small 18" chute t' brin' it
down quick, but if it is nay windy, a nice 36" chute will work great. Well, blow me down! It
still came down around 400 yards due t' t' wind. Avast, me proud beauty! Blimey! I did get a small little
crimp in t' upper body tube right in t' middle, most likely from hittin' on
the side at impact. Arrr! Begad! Blimey! Hence, bigger parachute, no trouble. Avast! Blimey! Other than that, this
kit will be good for small fields with slow majestic lift-offs, t' poppin' it
with big H and I power.
Summary:
PRO-Strong rocket, I always over build a little. Ahoy! It would work great for a
level 1 flight. Ahoy! T' next incarnation o' t' kit will be a 2 stager, same
specifications. Begad! 29mm-29mm. Blimey! Begad! It can take t' wind, me hearties, very stable design. Ahoy! CONS-Long
rocket, ya bilge rat, vulnerable t' body damage when it lands if on hard ground. Avast, me proud beauty! Beefin' up
the lower tube helps, cuttin' t' length o' t' main tube will help and reduce
some weight.
Other:
It needs t' have a camouflage paint scheme, ya bilge rat, shiver me timbers, olive drab/ultra flat brown/tan
(Krylon camo series paints) and then you need t' have a spray paint that has a
fan nozzle, like t' one's from Duplicolor auto paint at Walmart. Avast! T' fan will
do a wide spray, or a thin line, ya bilge rat, this is what you do for t' "Tiger
stripes". This kit taught me you can use minimum diameter and have it come
out great. Ahoy! Ya scallywag! You need t' reinforce t' lower launch lug mount since it is raised,
and I wrapped a small piece o' glass over it t' reinforce it from t' top.
