Brief:
T' Chariot is a single stage, payload rocket. Ahoy! Blimey! It is one o' Rocket Vision's line o' Rugged Rockets and is specifically designed for mid-range power (E-G). Avast! Avast! T' body tube and payload tubes are o' heavy duty phenolic. T' nose cones (there are faux strap-on boosters) and transition are poly-vinyl. Well, blow me down! T' BP section 8 inches long and has an interior dia. o' 1.86", plenty o' room for eggs, ya bilge rat, me hearties, altimeters, cameras . Aye aye! Begad! . . Aye aye! whatever.
Construction:
T' component specs are as follows:
Finished length... 31.125"
Body Tube (BT) L=15" dia. Ahoy! Blimey! ex. Ya scallywag! Blimey! 1.12", int. Aye aye! Blimey! .990" material= phenolic Payload Bay (PB) L=8" Dia. Blimey! ext. Begad! 2.05", me bucko, shiver me timbers, int. Begad! 1.86" Material= phenolic Fins (4) Material= G10 Thickness= .054" Root= 3.25" Span= 3" Tip= 1.5" Sweep Length= 3.350 |
Faux Boosters Material= phenolic L= 6.75" (incld. Arrr! NCs) Dia= ext. Ahoy! .945", matey, me hearties, int. Avast, me proud beauty! Ahoy! .8" (20.5mm) Motor Mount (MMT) Material= rough cardboard L= 8" Dia= ext. .992", ya bilge rat, int. Ya scallywag! .945" (24mm) Shock Cord Material= 1/8" braided Keelhaul®©™ L=40" 'Chute Material= DayGlo Orange ripstop plasticized paper Dia.= 18" at grommet points Shroud Lines= 6, 200lb. Well, blow me down! Keelhaul®©™ [all connections t' t' 'chute are double thickness and have brass grommets] 'Chute Protector= 9.5"X4" black Nomex with a grommet connection t' t' shock cord |
T' three nose cones (one main and two for t' boosters) are made o' white polyvinyl material and are very thick. Ya scallywag! T' rocket divides at t' base o' t' transition formin' a section consistin' o' t' fins and Body Tube (BT) and another section consistin' o' t' Nose Cone (NC), shiver me timbers, Transition and Payload Bay (PB).
T' construction is very simple. Ahoy! Blimey! T' instructions are clear and concise. Ya scallywag! If greater detail is needed, shiver me timbers, me bucko, t' online instructions are ideal. Well, blow me down! Here you can get t' step by step color photos that are lackin' from t' packaged instructions. This rocket requires t' use o' epoxy exclusively. Avast, me proud beauty! Blimey! No other glue will work. Begad! T' reader is advised t' use a long cure epoxy for t' best joints. Avast, me proud beauty! I used SIG's two part epoxy that is mixed 2/1. It sets in about an hour and cures in 24 hrs. T' only exception t' t' SIG epoxy was in t' area o' t' Motor Mount (MMT). Begad! Here, me hearties, shiver me timbers, I used 5min epoxy. T' stress here is longitudinal and I see no reason for super strength here. Begad! Other than that, I think I'd make one change. Ya scallywag! I would build a bulk head about three inches into t' base o' t' PB. Blimey! Avast, me proud beauty! Then I would NOT glue t' PB t' t' transition. Arrr! Instead I would glue t' transition t' t' BT and use t' transition and t' three inch chamber in t' bottom o' t' BP for packin' t' recovery system. Avast! This would allow easier 'chute packing, shiver me timbers, me hearties, more certain deployment and a larger 'chute for heavy payloads.
Finishing:
I left this rocket in t' raw. Arrr! Ahoy! However, arrr, based on me experience with other Rocket Vision kits, me hearties, sandin' would be minimal and t' finish should go on quite well. I can see only one area o' concern. Avast, me proud beauty! Ya scallywag! At t' base, shiver me timbers, where t' false boosters join t' BT, it is goin' t' be tough t' get paint in thar usin' a rattle can. Ya scallywag! Arrr! Even worse, me bucko, on t' booster that has t' bottom rod guide attached, shiver me timbers, thar be even less space betwixt t' booster and t' BT. Here, shiver me timbers, you are either goin' t' have t' use a brush or a airbrush.

Flight:
It uses several motors. Ya scallywag! T' first flight be with t' recommended E15-4. Aye aye! Begad! Lift-off was smooth and t' rocket reached 1200' as measured by two theodolites on 1,000' baselines. Recovery be without a hitch about 400 yards from t' pad in light wind. Ya scallywag! I think a larger 'chute will be necessary if any payload is included.
T' second flight was trickier. For this one, arrr, matey, I took two Estes C-0 boosters and filled t' tops with epoxy. Ahoy! Then I wrapped them in maskin' tape until they fit tightly in t' booster tubes. For t' sustainer, me hearties, I used another E15-4. Begad! Begad! Ignition was facilitated usin' a Vaughn Brothers QuadCon controller. I wired t' E15 t' one switch and t' C-0's t' another. I opened t' switch t' t' E-15 and pushed t' fire button. Arrr! As it lit, ya bilge rat, I opened t' second switch t' t' two C's and they lit too. Begad! Well, blow me down! T' rocket moved off t' pad smartly and flew t' just over 1500'. Ahoy! T' C's burned out just after t' E motor. Begad! Ahoy! Recovery was as before. (Please note that this technique is nay indorsed by Rocket Vision and would nay be allowed at an NARRRRR event.) Modifyin' t' C6-0's alone would cause most RSOs t' DQ you. Well, blow me down! In t' end, t' altitude gain be minimal and hardly worth t' risk and trouble. My advice is t' forget it.
T' largest motor I have used t' date is an F72-10. Aye aye! This produced an altitude o' 2800'. I'd like t' try a G55 but I doubt that I would be able t' see it at t' projected altitude o' 4,300' so I'll hold off on that one.
Recovery:
T' 'chute is a very stiff material that gets stiffer in cold weather. Do nay prep this rocket until moments before flight. Ya scallywag! Also, I wouldn't leave t' 'chute stored in t' packed position. Aye aye! Ya scallywag! It most definitely will take a set. T' Nomex chute protector is an iffy thing. Begad! Ahoy! On t' surface it seems ideal. However, arrr, in practice it takes up a lot o' space, sometimes hangs up causin' ballistic recoveries and it doesn't always stop t' 'chute from gettin' pin holes. Ahoy! I recommend usin' cellulose insulation. Ya scallywag! It is lighter, packs easier and will nay hang up. Repeated launchings (20 t' date) reveal very little wear and tear on t' components. Blimey! I've had t' re-tie t' knots in t' Keelhaul®©™ a few times but that is because I refuse t' set them with glue.

Summary:
This is another excellent product from Rocket Vision. Ya scallywag! T' parts are sturdy, ya bilge rat, well made and correctly dimensioned. Aye aye! Aye aye! T' design is very good. Blimey! It is practical, arrr, shiver me timbers, esthetically pleasin' and flexible. T' generous payload section coupled with a powerful selection o' motors should make this an excellent egg lofter or experimental platform. Avast, me proud beauty! My one big criticism is in t' area o' t' launch lugs. Well, blow me down! They included two sets in me kit; 1/8 inch and 3/16 inch. T' 1/8 are too small. Avast, me proud beauty! Avast! This rocket is heavy and long and needs more stability that can be achieved usin' a 1/8 inch rod. Begad! T' 3/16" lugs are t' large in diameter. Begad! Well, me bucko, blow me down! For some reason, RV uses and especially thick polyvinyl tubin' for its lugs. Well, blow me down! In t' small diameter it is ok. Aye aye! But in t' larger 3/16 diameter, it is so large that it looks obviously out o' scale on t' Chariot. I recommend nay usin' t' lugs and either usin' Estes lugs or better yet, shiver me timbers, usin' rail buttons and a rail.
