Rocket PicBrief:
Let me start by tellin' you that me Level 2 certi-fication flight be not successful. Begad! But that has nay deterred me from recommendin' this kit. Ya scallywag! Ya scallywag! 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, me bucko, I know this model will make it durin' me second attempt. Ahoy! Well, blow me down! Completed, me bucko, this model is quite impres-sive. Ya scallywag!

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

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

Kit included cut and sanded 3/16” aircraft quality plywood fins, high strength airframe tube and couplers, me hearties, centerin' rings, bulkhead plate, high quality hardware package, arrr, 54 mm motor tube, plastic nose and tail cone, computer designed and cut vinyl decals. Begad! 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. Well, blow me down! Avast, me proud beauty! T' longest part o' this project was t' buildin' o' the aft section. Avast, me proud beauty! With a boat tail as-sembly and 9 fins t' sand and align, the slower I went produced terrific results. Arrr! Well, blow me down! As t' instruc-tions tell you, the care that you take durin' these steps will insure a well built and solid rocket. Arrr! A hand sander and dremel came in very handy, especially with t' talon fins. Aye aye!

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

I purchased an avionics bay for this rocket, but chose nay t' use it. The rocket and can be built two ways, with or without t' bay. Ya scallywag! Blimey! I did nay feel that I was ready for t' electronics, but I now realize that if I am goin' t' play in t' higher power stuff, ya bilge rat, shiver me timbers, 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! I wanted to have it able t' use a K550W. Avast, me proud beauty! Avast! So I built it strong. T' rocket weigh in at 5.5 lbs. Avast, me proud beauty! 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. Aye aye! Arrr! After sandin' and prep, I applied two coats o' primer followed by three coats o' finishin' paint. Begad! Well, arrr, blow me down! I used white high gloss paint for the aft section and Green Krylon for t' forward section. Arrr! T' Nose cone was finished in silver. Aye aye! Binder pro-vided excellent decals t' finish t' rocket and give its great look. Aye aye! Usin' me garage as me paint studio never sits well with my wife, but she has gotten use t' it.

Rocket PicFlight:
My level 2 certification flight was set for WTGG in September. Avast! Avast, arrr, me proud beauty! I arrived at the field a late morn-ing, 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. I checked in with every-one that was goin' t' help me with t' flight. After watchin' 4-6 flights t' gage t' wind, I started t' build t' J350W motor that I be gong to use. Well, blow me down! Ahoy!

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

Back t' t' launch. As a mentioned t' rocket is quite impressive when finished, and I believe this be t' be t' only Level 2 launch o' t' day. Begad! So it got a little o' attention. Arrr! T' rocket be loaded on t' Impulse Aerospace Quad Pod, and we were readin' t' go. Avast, me proud beauty! Ya scallywag! T' wind was at about 5 miles an hour out of t' south west. 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. Begad!

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

Recovery:
With t' chute fully deployed with t' rocket appearin' in good shape. The extra height that we saw allowed t' drift into t' corn field about two hundred yards in. 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. Ya scallywag!

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

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

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. Well, blow me down! 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. Avast! Ahoy! I will continue t' learn and gain experience, shiver me timbers, and will always seek t' advice from others that have gone before me. Avast! Well, matey, blow me down!

This is a great rocket, and I recommend it t' anyone. Ya scallywag! T' failed attempt was not that o' t' rocket, 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!
