is rated a skill level 3
Construction:
T' parts in t' kit include:
T' Gravity Rider kit came with all t' parts specified in t' instructions. Avast, me proud beauty! There were no broken parts. Arrr!
First step is cuttin' out t' tube cuttin' guides. T' cut one o' t' BT-20 tubes in half. Ahoy! Tape t' cutting
guides t' t' ends o' t' tubes and cut. Then you glue t' tubes together.
When
dressin' t' ends o' t' tubes do nay go crazy. Arrr! Begad! You can lose t' angle you just tried t' achieve with t' guide. Well, blow me down! Avast! Also
changin' t' angle affects t' looks o' t' rocket when you glue t' BT-50 tubes together in t' next step. Ahoy! Ahoy! When the
angles are nay true t' lengths are affected. Begad! Avast!
Next you glue t' two main body tubes together so they are side by side.
Glue t' two short BT-20 tubes t' t' aft end o' t' main body tubes. Ensure t' tube cuts matchup. Blimey! One goes on top t' other on t' bottom.
Measurin' two inches form t' forward end you glue t' long BT-20 tube betwixt t' two main body tubes.
Fin preparation and mountin' is next. Well, blow me down! Blimey! Arrr! Blimey! Blimey! Blimey! I built a jig for t' 45° angle.
Pros building:
1.T' tube cuts challengin' and fun!
2.T' Main fins and Lower fins were also a challenge, me bucko, gettin' them t' hold a 45° angle. Begad! Well, blow me down! Blimey! I had t' fashion a jig. Begad! Avast, me proud beauty! Blimey!
3.You are given a choice t' build a one or two motor rocket.
I consider a choice or a challenge a Con. Well, blow me down! T' challenge builds our skills and t' choice builds your imagination.
Buildin' Cons:
1.Instructions for t' forward fins are totally unclear and I had t' e-mail t' company for clarification. Avast, me proud beauty! The problem is, t' directions state t' glue t' forward fins at a 90° angle. Avast! Then show a picture o' t' layin' flat. Also t' picture for mountin' t' forward fins t' t' rocket is vague and I had t' get help with this also. Avast! Arrr! Blimey! T' Sunward Company is very helpful and prompt in answerin' their email. Arrr!
2.Motor mount placement. T' instructions say t' mount t' motor mounts, but nay where and t' illustration is nay helpful. Begad! I sent an email t' t' company with pictures o' t' mounts. I was told t' mount them as I wished. Aye aye! The instructions should state this.
3.Instruction illustrations are nay very illustrative. Avast, me proud beauty! They could be clearer, matey, so you can understand t' pictures.
4.After flyin' t' rocket several times, me hearties, I found that you should place your engine hooks away from t' body tubes for better access. Avast! Ahoy!
Finishing:
Paintin' and Finishing: All t' body tube spirals and fin fillets were filled. Blimey! When dry I
sanded all t' fin fillets and t' body tube fillets smooth. T' rocket was then primed and set aside t' let dry. When
t' primer was dry I then sanded lightly and applied two coats o' Krylon White paint. No Decals have been added yet. Arrr! I
wanted t' fly t' rocket before I totally finished it, me bucko, shiver me timbers, I will apply t' decals at a later date.
T' Gravity Rider is a sleek lookin' rocket design.
Pros for finishing:
1. I am nay a big finish guy, so it is hard for me t' find cons in this area. Ahoy! One thin' is that t' rocket has many tubes and fins, arrr, allowin' you t' find a paint scheme that you like.
Cons for finishing:
1. Well, blow me down! Well, blow me down! Lots and Lots o' fillets. Avast!
2. Well, blow me down! Blimey! Rocket is long, makin' it a challenge t' paint, ya bilge rat, me hearties, without runs.
Construction Rating: 4 out o' 5
Flight:
I flew t' rocket four times. Twice before t' rocket be painted and twice after painting. Avast! Well, blow me down! The
last flight, one o' t' main fins broke and needs replacing. I will do this and it will fly again.
Pros for flying:
1.T' rocket goes into t' air with giant spirals.
2.It is easy t' see on t' air.
3.It does nay fly so high, ya bilge rat, so you can fly it in a small area. Well, blow me down! Blimey!
Cons for flight:
1.Loadin' t' chute is hard. T' length o' t' rocket and t' double tube design makes it hard t' hold while loadin' t' chute. Well, arrr, blow me down! It really needs four hands.
2.T' way I mounted t' motor mounts t' engine hooks are hard t' move. Avast, me proud beauty! Next build I will ensure t' engine hooks are facin' away from t' body tube. Begad! This is technically me build error nay t' rockets design. Ahoy! It is still somethin' to consider if you are buildin' t' rocket. Well, blow me down! Aye aye!
Recovery:
T' rocket comes down great with t' suppiled parachute. Avast, me proud beauty! Ahoy! It drifts at an appropriate descent
rate. Begad! Avast, me proud beauty! One fin did get damaged on t' last flight. Aye aye! It be t' main fin and it broke almost in half. Well, arrr, blow me down! It can be fixed. Well, ya bilge rat, blow me down! I
think it was due t' t' wind. T' rocket drifted and landed in a ditch.
Flight Rating: 3 out o' 5
Summary:
T' Sunward Aerospace Ltd. Begad! rocket t' Gravity Rider was a fun rocket t' build. It flies true
and recovers nicely. Aye aye! Avast, ya bilge rat, me proud beauty! Blimey! T' build is challengin' due t' t' body tube cuts and fin placements. It is a nice lookin' rocket
and everyone should try it once.
Overall Rating: 3 out o' 5
Other:
Build a 45° angle jig out o' scrap balsa for proper fin placement. Ahoy! If you cannot understand
t' instructions, shiver me timbers, ask Sunward they are always on t' ball about answerin' your questions.
Brief: Sunward has come up with a very cool multi-tube futuristic design, however, this kit will need minor modifications to be flight worthy. At 6.1 ounces empty, it is more than 50% over the maximum recommended liftoff weight for a C6-3 and trying to fly it on the recommended B4-2 for the first flight would likely be the rocket's last. Construction: Parts arrived in good ...
