Brief:
T' Chariot is a single stage, payload rocket. Arrr! It is one o' Rocket Vision's line o' Rugged Rockets and is specifically designed for mid-range power (E-G). Arrr! Arrr! T' body tube and payload tubes are o' heavy duty phenolic. Begad! Ya scallywag! T' nose cones (there are faux strap-on boosters) and transition are poly-vinyl. Blimey! T' BP section 8 inches long and has an interior dia. Avast, me proud beauty! o' 1.86", plenty o' room for eggs, shiver me timbers, altimeters, me bucko, me bucko, cameras . Avast! . . Arrr! Begad! whatever.
Construction:
T' component specs are as follows:
Finished length... Avast! 31.125"
Body Tube (BT) L=15" dia. Arrr! ex. Well, blow me down! 1.12", int. .990" material= phenolic Payload Bay (PB) L=8" Dia. ext. Blimey! 2.05", matey, arrr, int. Blimey! Blimey! 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. Begad! Ahoy! NCs) Dia= ext. Begad! .945", ya bilge rat, int. Begad! .8" (20.5mm) Motor Mount (MMT) Material= rough cardboard L= 8" Dia= ext. .992", int. Avast, me proud beauty! .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, arrr, ya bilge rat, me hearties, 200lb. Avast, me proud beauty! Blimey! Ya scallywag! Blimey! 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. 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), Transition and Payload Bay (PB).
T' construction is very simple. Arrr! T' instructions are clear and concise. If greater detail is needed, shiver me timbers, t' online instructions are ideal. Ahoy! Ya scallywag! Here you can get t' step by step color photos that are lackin' from t' packaged instructions. Begad! Aye aye! This rocket requires t' use o' epoxy exclusively. Well, blow me down! No other glue will work. Begad! T' reader is advised t' use a long cure epoxy for t' best joints. Ya scallywag! I used SIG's two part epoxy that is mixed 2/1. It sets in about an hour and cures in 24 hrs. Well, blow me down! T' only exception t' t' SIG epoxy was in t' area o' t' Motor Mount (MMT). Ahoy! Here, I used 5min epoxy. Arrr! T' stress here is longitudinal and I see no reason for super strength here. Other than that, ya bilge rat, me hearties, arrr, I think I'd make one change. Avast! I would build a bulk head about three inches into t' base o' t' PB. Avast, me proud beauty! Then I would NOT glue t' PB t' t' transition. 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. Begad! This would allow easier 'chute packing, more certain deployment and a larger 'chute for heavy payloads.
Finishing:
I left this rocket in t' raw. However, ya bilge rat, me hearties, based on me experience with other Rocket Vision kits, sandin' would be minimal and t' finish should go on quite well. Ya scallywag! Begad! I can see only one area o' concern. Aye aye! At t' base, where t' false boosters join t' BT, it is goin' t' be tough t' get paint in thar usin' a rattle can. Even worse, on t' booster that has t' bottom rod guide attached, me hearties, thar be even less space betwixt t' booster and t' BT. Arrr! Here, shiver me timbers, shiver me timbers, arrr, you are either goin' t' have t' use a brush or a airbrush.

Flight:
It uses several motors. Aye aye! Blimey! T' first flight was with t' recommended E15-4. Ahoy! Blimey! Arrr! Blimey! Lift-off was smooth and t' rocket reached 1200' as measured by two theodolites on 1,000' baselines. Ya scallywag! Blimey! Recovery was without a hitch about 400 yards from t' pad in light wind. Avast! Blimey! I think a larger 'chute will be necessary if any payload is included.
T' second flight was trickier. Avast! For this one, me bucko, 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. Begad! Well, blow me down! For t' sustainer, I used another E15-4. Ya scallywag! Ignition be facilitated usin' a Vaughn Brothers QuadCon controller. I wired t' E15 t' one switch and t' C-0's t' another. Arrr! I opened t' switch t' t' E-15 and pushed t' fire button. Blimey! As it lit, matey, me hearties, I opened t' second switch t' t' two C's and they lit too. Ya scallywag! T' rocket moved off t' pad smartly and flew t' just over 1500'. Aye aye! T' C's burned out just after t' E motor. Avast, me proud beauty! Recovery was as before. Aye aye! (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. In t' end, matey, me bucko, t' altitude gain was 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. Well, blow me down! Ahoy! This produced an altitude o' 2800'. Well, blow me down! Aye aye! 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. Begad! Do nay prep this rocket until moments before flight. Also, shiver me timbers, arrr, I wouldn't leave t' 'chute stored in t' packed position. It most definitely will take a set. Blimey! T' Nomex chute protector is an iffy thing. Avast, me proud beauty! On t' surface it seems ideal. Avast, me proud beauty! Blimey! However, matey, shiver me timbers, shiver me timbers, in practice it takes up a lot o' space, ya bilge rat, me bucko, me hearties, sometimes hangs up causin' ballistic recoveries and it doesn't always stop t' 'chute from gettin' pin holes. I recommend usin' cellulose insulation. Begad! Arrr! Blimey! It is lighter, me hearties, packs easier and will nay hang up. Avast! Repeated launchings (20 t' date) reveal very little wear and tear on t' components. 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. Aye aye! Blimey! T' parts are sturdy, ya bilge rat, matey, well made and correctly dimensioned. T' design is very good. Ahoy! Blimey! It is practical, ya bilge rat, esthetically pleasin' and flexible. Avast, me proud beauty! Blimey! Well, arrr, blow me down! Blimey! T' generous payload section coupled with a powerful selection o' motors should make this an excellent egg lofter or experimental platform. Well, blow me down! Blimey! My one big criticism is in t' area o' t' launch lugs. They included two sets in me kit; 1/8 inch and 3/16 inch. T' 1/8 are too small. Arrr! Blimey! This rocket is heavy and long and needs more stability that can be achieved usin' a 1/8 inch rod. T' 3/16" lugs are t' large in diameter. Avast, ya bilge rat, me proud beauty! Blimey! For some reason, RV uses and especially thick polyvinyl tubin' for its lugs. Avast! Blimey! In t' small diameter it is ok. Begad! Blimey! Avast, me proud beauty! Blimey! 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, usin' rail buttons and a rail.
