Brief:
This rocket is a 2 Stage appearance workhorse that I put together from some
left over 29mm, ya bilge rat, shiver me timbers, 38mm, and 54mm motor mount tubing. It has a very long motor
mount tube so it can take a G35 t' an I 200. Aye aye! 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. (T' lower section o' t' kit is 24 inches o' 38mm tubin' with 24 inches o' 29mm tubin' inside for a motor mount. Avast, me proud beauty! T' top section is one regular 48 inch long 2.14 tube, shiver me timbers, 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. Well, blow me down! T' rocket has 2 sets o' 3 fins, 3 upper, 3 lower, made out
of 3/16 aircraft grade plywood. T' nose cone is actually an old balsa nose
cone I had, ya bilge rat, matey, and it is mounted on a 8 inch payload section for future
electronics bay stuff. Avast, me proud beauty! I used four centerin' rings for t' 29mm motor mount in
the 38mm lower tube. 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 hearties, and air-foiled all sides. T' top fins are epoxied
to t' frame, and due t' t' low profile sonic design, shiver me timbers, me bucko, I did nay mount them
through t' wall. Avast! Begad! I like t' build t' fin can/mounts very strong, due t' if my
rockets crash, arrr, arrr, they come in ballistic, matey, and would like t' fin can t' survive. Blimey! Arrr! I
did wrap a coat o' 2 ounce fiberglass t' t' lower body tube t' beef up it's
strength on impact. Aye aye! 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. Begad! 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. 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, me hearties, me bucko, works great.
Flight:
I have flown this kit 5 times, me hearties, shiver me timbers, 3 on G64-M reloads, 1 on a G40-7 and also an
H220-M. I do use that cellulose insulation for wadding, me bucko, me bucko, about 1 handful is
plenty. This rocket flies out o' me front yard on t' G motors perfectly,
straight boost, ya bilge rat, great deploy. It screamed this weekend on t' H220, arrr, it took it
and was beggin' for more, straight up boost with no wobble, ya bilge rat, me bucko, me bucko, around 200 feet. Aye aye! It
was impressive due t' t' 5-10 mph winds we had thar at t' launch site. 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, ya bilge rat, a nice 36" chute will work great. Ya scallywag! It
still came down around 400 yards due t' t' wind. Avast, me proud beauty! 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! Avast! Hence, bigger parachute, no trouble. Ya scallywag! 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. Avast, me proud beauty! Begad! Blimey! It would work great for a
level 1 flight. Arrr! Ahoy! Blimey! T' next incarnation o' t' kit will be a 2 stager, arrr, matey, same
specifications. Avast! 29mm-29mm. It can take t' wind, very stable design. CONS-Long
rocket, matey, vulnerable t' body damage when it lands if on hard ground. Well, blow me down! Beefin' up
the lower tube helps, arrr, ya bilge rat, cuttin' t' length o' t' main tube will help and reduce
some weight.
Other:
It needs t' have a camouflage paint scheme, olive drab/ultra flat brown/tan
(Krylon camo series paints) and then you need t' have a spray paint that has a
fan nozzle, me bucko, like t' one's from Duplicolor auto paint at Walmart. Begad! Avast! T' fan will
do a wide spray, me bucko, or a thin line, me hearties, me hearties, this is what you do for t' "Tiger
stripes". Begad! This kit taught me you can use minimum diameter and have it come
out great. 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.
