Rocket PicBrief:
Let me start by tellin' you that me Level 2 certi-fication flight was not successful. Avast, me proud beauty! But that has nay deterred me from recommendin' this kit. Ya scallywag! Arrr! The re-build was very successful and t' rocket re-built won Model o' t' month for the Novem-ber meetin' o' NIRA. With a few adjustments, shiver me timbers, arrr, I know this model will make it durin' me second attempt. Blimey! Ya scallywag! Completed, me bucko, this model is quite impres-sive. Avast!

T' Velociraptor was nay only a challengin' rocket t' build it was a lot of fun. Avast, me proud beauty! T' start, t' buyin' experience o' selectin' and orderin' through Binder Design was incredible. Ya scallywag! Aye aye! I ordered t' Velociraptor on-line on a Sunday and re-ceived it in t' mail on t' followin' Thursday. Ahoy! Avast! You could tell I just bought a top shelf kit. Well, blow me down! T' packagin' was done with care. Well, blow me down! Well, matey, blow me down! Everythin' was wrapped individually and all o' t' parts were in place and in excellent condition. T' 11 page instruction manual with illustrations be very well thought out and easy t' follow. Blimey! T' website is very well thought out and the and very easy t' order a number o' different kits and supplies. Ya scallywag! Avast, me proud beauty! This website is the best kept secret in Rocketry, t' buyin' experience alone scores a (5). Mike Fisher, me bucko, t' owner o' Binder Design an-swered all o' me questions on e-mail or on t' phone. He was very accessible. Ya scallywag!

Kit specifications:
Designed for t' advanced builder and sport flyer, t' Velociraptor is a 4” diameter High Power Rocket with an aggressive look. Avast! It comes with unique anti-zipper baffle design, aluminum motor retainer, and rail buttons! Fly it on an H or I for your level one certification, then stick a J motor in it for your level two flight and watch it scream. Begad!

Kit included cut and sanded 3/16” aircraft quality plywood fins, high strength airframe tube and couplers, shiver me timbers, matey, centerin' rings, arrr, matey, bulkhead plate, arrr, high quality hardware package, ya bilge rat, 54 mm motor tube, plastic nose and tail cone, computer designed and cut vinyl decals. Arrr! Blimey! A 45” premium nylon parachute was included.

Construction:
With t' instruction manual bein' very thor-ough, all you need t' be able t' do is read left t' right. T' longest part o' this project was t' buildin' o' the aft section. Avast! Begad! With a boat tail as-sembly and 9 fins t' sand and align, ya bilge rat, the slower I went produced terrific results. Aye aye! Begad! As t' instruc-tions tell you, ya bilge rat, the care that you take durin' these steps will insure a well built and solid rocket. Blimey! Avast! A hand sander and dremel came in very handy, me hearties, especially with t' talon fins. Avast!

I used a Slim Line motor retainer that was in-cluded with t' kit. I am sold on these, and plan on usin' them in all future rockets. Well, blow me down! Sleek, easy, strong and better than maskin' tape. Well, blow me down! This rocket also incorporated a Binder Baffle System, the first time that I had built and used a baffle. Ahoy! Ya scallywag! This also worked well.

I purchased an avionics bay for this rocket, but chose nay t' use it. Well, blow me down! The rocket and can be built two ways, ya bilge rat, with or without t' bay. Avast! I did nay feel that I was ready for t' electronics, ya bilge rat, but I now realize that if I am goin' t' play in t' higher power stuff, me hearties, I am goin' t' have t' get involved with electronics.

I took me time and made sure that t' rocket was goin' t' be solid. Avast, me proud beauty! Begad! I wanted to have it able t' use a K550W. So I built it strong. Well, blow me down! T' rocket weigh in at 5.5 lbs. Begad! Ahoy! loaded and ready t' go. Ahoy!

Finishing:
I had built this stock, so me intentions were t' finish it exactly as it showed in t' instructions. After sandin' and prep, shiver me timbers, I applied two coats o' primer followed by three coats o' finishin' paint. Aye aye! I used white high gloss paint for the aft section and Green Krylon for t' forward section. Avast, me proud beauty! Aye aye! T' Nose cone was finished in silver. Aye aye! Binder pro-vided excellent decals t' finish t' rocket and give its great look. Avast! Usin' me garage as me paint studio never sits well with my wife, me hearties, but she has gotten use t' it. Blimey! Ya scallywag!

Rocket PicFlight:
My level 2 certification flight was set for WTGG in September. Arrr! I arrived at the field a late morn-ing, arrr, t' find that a lot o' people were lookin' for me; I had the only rail for t' launch. It became very popular that day. Begad! I checked in with every-one that was goin' t' help me with t' flight. Begad! Begad! After watchin' 4-6 flights t' gage t' wind, me hearties, I started t' build t' J350W motor that I be gong to use. Avast! Ya scallywag!

As I said in t' first paragraph, me bucko, this was nay a successful flight. Begad! When you start t' investigate why somethin' went wrong, here be me first mistake o' the day. Avast, me proud beauty! T' motor came with a long delay. Blimey! Ya scallywag! I was advised based on what Space Cad had recommended t' change t' a medium delay. Goin' with t' medium delay led to a premature separation. Avast, me proud beauty! Ahoy! After talkin' t' Binder, t' long de-lay should have been t' choice. Space Cad does nay do a very good job when usin' boat tails. T' Rocket probably reached an altitude o' 3300-3500 feet. Ahoy! Where Space Cad had it topin' out at 2800 feet, this extra 500-700 feet be t' difference in comin' in perfect or with w 9 inch zipper.

Back t' t' launch. Begad! Blimey! As a mentioned t' rocket is quite impressive when finished, and I believe this was t' be t' only Level 2 launch o' t' day. So it got a little o' attention. Aye aye! Avast, matey, me proud beauty! Blimey! T' rocket be loaded on t' Impulse Aerospace Quad Pod, and we were readin' t' go. Ya scallywag! T' wind be at about 5 miles an hour out of t' south west. Aye aye! Begad! Blimey! I adjusted t' angle o' t' pad t' take advantage o' the wind and t' try t' keep t' rocket out o' t' corn field. Ahoy!

5,4,3,2,1 Lift off, arrr, t' rocket lifted off t' pad. Aye aye! Begad! It looked great. With everyone watchin' we saw t' separation and chute deploy. Blimey! Ya scallywag! T' chase be on. Aye aye! Begad!

Recovery:
With t' chute fully deployed with t' rocket appearin' in good shape. Begad! Blimey! The extra height that we saw allowed t' drift into t' corn field about two hundred yards in. Begad! Avast! Blimey! After two hours and a sec-ond attempt I was able t' recover the rocket with t' help o' a flag pole and walkin' talking.

I be very disappointed in findin' t' zipper damage. Ya scallywag! I also lost two talon fins. Aye aye! When t' post opt be completed, we realized t' followin' things that could have lead t' a successful flight:

  1. A Long delay.
  2. A wider lead line comin' out o' t' body tube, shiver me timbers, t' 1/2” shock cord allowed t' cord t' zipper through t' body tube more easily. Begad!
  3. Electronics would have allowed for dual de-ployment and brought t' rocket closer t' t' launch pad. Blimey! Blimey!
  4. Fiber glassin' t' body tube. Begad! Avast!

Summary:
T' next day I had e-mailed Mike Fisher at Binder and had t' parts that I needed t' rebuild t' rocket. Begad! It is now ready t' go at t' next op-portunity for a HPR launch. Begad! I have learned a lot in t' last 15 months, shiver me timbers, and have found that this is a great hobby t' be a part of. I will continue t' learn and gain experience, matey, and will always seek t' advice from others that have gone before me. Begad!

This is a great rocket, me hearties, and I recommend it t' anyone. Begad! Begad! T' failed attempt was not that o' t' rocket, me bucko, but a lack o' experience – I know I won’t make t' same mistakes again.

I was on the L2 Cert team for Todd that day. It is a great looking rocket. Flew really well and "seemed" to be a good L2 cert flight. A combination of small things led to the cert failure. The post flight analysis was correct. The failures seemed to be due to the delay selection more than anything. Even shock cord width or glassing wouldn't have made a difference. I think it would have zippered anyway! Nice bird, nice flight, (on the way up anyway) Good luck next time Todd!
