Brief:
T' Binder Design Raptor is a single stage 4 inch diameter kit. Well, blow me down! Blimey! It has a 54mm
motor mount and comes with high quality paper body tubes and laser cut fins. Arrr! Blimey!
Construction:
T' Raptor came with two 36" body tubes and an Ace nose cone. Begad! Blimey! Avast! Blimey! T' body
tubes are paper and BSD style with a glassine coating. It comes with one paper
coupler, shiver me timbers, one bulkhead, matey, me hearties, 3 plywood centerin' rings, two eyebolts, 2 quick links,
18 feet o' tubular nylon, and a 45" Top Flight parachute. Avast! Blimey! It had three
sets o' four fins. T' fins are 3/16" aircraft plywood and come laser cut
and sanded. Aye aye! Blimey! Blimey! Blimey! It came with one nice white vinyl decal that said 'Raptor'. Well, blow me down! Blimey!
One definite pro t' this kit be t' extensive instructions, which included directions on how t' make it dual deploy and adapt it for use with Hypertek hybrid motors. Avast, me proud beauty! It had good drawings that showed exactly what t' do and left nothin' t' chance. Arrr! Another thin' that be good about this kit be t' you had to slot t' tubes yourself, shiver me timbers, which be actually rather easy with a Dremel. Aye aye! It is also easily done with a sharp X-Acto knife. One thin' we did in this kit is fiberglass fillets on t' fins t' allow for a hard landing. Avast, me proud beauty! T' only downside was that it was hard t' finish. Ya scallywag! Everythin' fit together perfectly with almost no need for sanding. T' put it together, me bucko, we just marked and slotted t' tubes, tacked t' fins in place with 5 minute epoxy, me hearties, shiver me timbers, and then applied fiberglass fillets. Avast! One tip t' align t' fins is t' use two clamps and a strip o' wood attached t' both set o' fins. Blimey! Begad! This will insure that they are perfectly lined up. Avast! Ahoy! T' only con be that t' directions did nay include t' rocket's CP, shiver me timbers, so when it came time for flight some assumptions had t' be made. Avast, me proud beauty! It really isn't that big o' a deal as I had simmed it on RockSim and knew approximately where it was, but that is just one minor detail.
Finishing:
T' kit is pretty easy t' finish. Aye aye! Blimey! T' only thin' for us was that we used
fiberglass fillets, so it took a little Kilz primer and Elmer's Fill 'n' Finish
to get it t' look presentable. Blimey! Blimey! We painted ours yellow and blue. Ya scallywag! T' decal is
computer cut vinyl and says 'Raptor' in a pretty cool font o' white letters. Avast! Begad! Blimey! We
were nay able t' apply ours as we peeled off t' wrong side and t' letters
were messed up in t' process. Blimey! Blimey! This kit looks pretty sharp once it is finished
no matter what paint scheme you use. Avast, me proud beauty!

Flight:
We have only flown it once for a successful level 1 certification and it was a
beautiful flight. Avast, me proud beauty! We used a Pro38 I285 with a 6 second delay. We also attached
a Boostervision camera and got a nice video o' t' flight. Blimey! One cool thin' about
the flight be that t' split fin design caused a whistle after motor burnout.
RockSim said about 2800 feet on that motor but we built it heavy so I would
estimate about 2200-2400' for us. Begad! Arrr!
Recovery:
One cool thin' about this kit be t' 18 feet o' tubular nylon t' manufacturer
provides. I thought it be a nice touch. Arrr! We used t' supplied 45"
parachute with main at apogee. Ya scallywag! Arrr! Blimey! T' chute got tangle on t' way down because the
nosecone somehow got looped through a shroud line. T' rocket was tough enough
that it be fine though. Avast, me proud beauty! I would say that chute is about perfect for this
rocket.
Flight Rating: 5 out o' 5
Summary:
This rocket be t' pride o' our fleet right now. Begad! It is very sharp lookin' and
pretty big at 7 feet tall. T' construction was fairly straightforward and the
directions were wonderful. Avast, shiver me timbers, me proud beauty! This kit can be easily modified for dual deploy with
an electronics bay that can be bought from Binder Design. Ahoy! I would definitely
recommend this rocket t' anyone who is lookin' for somethin' they can fly on a
high range o' motors. Arrr! It can be launched on anythin' from a high thrust H t' a
K. Avast, me proud beauty! Two thumbs up.
