Oatlander background history:
T' Oatlander was inspired by t' Oat cereal box rockets and strongly influenced by t' original Marz Lander, me bucko, arrr, thus t' name. Oat - Lander

T' rocket was built almost entirely from recycled or found parts with t' exception o' t' core body tubes and t' fin material. A great amount o' design emphasis was placed on saving weight. Avast! Some o' t' other oat box rockets have been on t' heavy side, me hearties, for rockets. T' single most significant weight savings was in me selection o' t' oat box its self. Blimey! Blimey! Instead o' the conventional wound construction I was able t' find a box that was single layer o' fiber board. Carefully selectin' material can make a difference. Even though it's a fatroc, arrr, it doesn't have t' be heavy.

As I said with t' exception o' t' core body tubes and the fin material all other materials were salvaged. T' Oatlander could be built usin' purchased materials o' course.

Construction:
All construction be done usin' basic construction techniques. Begad! This is really nay an advanced rocket, shiver me timbers, it just took some time t' build.

T' design uses a core structure o' three BT-20 tubes around a central BT-50 tube. This gives structural integrity and allows flexibility in engine use. Well, blow me down! Ya scallywag! T' core structure is then attached t' three bulk heads cut from 1/8" foam board t' fit t' inside diameter o' t' oat meal box. Positioned one each at t' top and bottom and one approximately 3" from t' bottom t' add support where t' fins will anchor. Aye aye! T' foam board was salvaged from an old poster.
T' oat meal box is then attached t' t' bulk heads. Arrr! Double check alignment before applyin' glue. Aye aye! Locate t' launch lug holes adjacent t' t' core structure tubes. 
A transition adaptor be cut from a discarded file folder. Blimey! This sits on t' top o' t' sustainer and matches a circle cut from 3/32" balsa that is glued in place on t' core structure. Begad! Insert t' launch lugs and trim off excess.

T' capsule is made from a foam ostrich egg. Ya scallywag! Well, arrr, blow me down! A stagin' coupler is glued into t' base o' t' egg t' fit into t' BT-50 and one for each o' t' surroundin' tubes. Begad! Be certain t' align t' tubes so that it will be easier t' fit everythin' together, me bucko, ya bilge rat, especially t' couplers and t' capsule.
Use t' fin alignment wrap and index t' sustainer body with six equally spaced marks that run at least 4" up from t' bottom.

T' landin' gear, arrr, that be t' longest fin, arrr, ya bilge rat, is glued first and touches t' bottom o' t' sustainer. Ahoy! Once t' landin' gear/fins have dried add t' buttresses, me hearties, on each side o' t' landin' gear. Avast! T' buttresses are glued along t' root edge t' t' sustainer and t' t' side o' t' landin' gear. Blimey! Glue t' landin' gear feet t' t' ends o' each landin' gear leg. Arrr! T' shish kabob skewers that represent hydraulics are next. Each o' t' landin' gear feet gets one that goes up t' the sustainer body. Blimey! You can try t' measure out and cut t' correct miter on t' body end o' t' skewers, but what I did was t' make a small hole in t' sustainer body and stick in t' skewer with t' application o' a little glue. Avast, me proud beauty! No measuring. Blimey! T' skewers attach (enter) t' sustainer at 3" above t' bottom. They are positioned in betwixt t' paired buttresses above each o' t' landin' gear legs.

Finishing:
Seal. Avast, me proud beauty! Arrr! Sand. Begad! Paint and finish t' taste. I like cinnamon and brown sugar on me oat meal.

Flight Notes:
05/12/01: KCAR May launch at Shawnee Mission Park. Avast, me proud beauty! Blimey! D12-3. Well, blow me down! Weather was perfect.  No clouds, ya bilge rat, ya bilge rat, little wind. T' club had a record number o' launches.  T' Oatlander was prepared and inspected. Arrr! I was usin' a borrowed nylon chute which fit very snug in t' tube. Begad! T' launch went perfect. Straight up, ya bilge rat, no wobble. Ahoy! Arced over at apogee and t' ejection charge blew t' motor out t' back. Aye aye! Begad! No chute deployment. Ya scallywag! Arrr! T' Oatlander took a core sample. Ahoy! Begad! T' damage was surprisingly slight. T' outer body detached from the bulkheads and some damage t' t' nose capsule. Avast, me proud beauty! Good flight, bad landing. I be advised that t' engine hook may have been too loose. A single wrap o' tape would have made t' engine secure and might have prevented this.

05/13/01: D12-3. Avast, me proud beauty! After makin' quick repairs, matey, we decided t' try again. Avast, me proud beauty! Avast, me proud beauty! This time I made t' engine secure and used a plastic parachute. Avast! T' fit was better in t' tube. Ahoy! Most o' t' damage had been repaired with t' exception of t' circle at t' top o' t' transition section bein' broken. The wind was higher than t' previous day, matey, me bucko, arrr, but it was just as hot. Avast, me proud beauty! We launched a soundin' rocket t' test t' wind. Aye aye! Ahoy! Good flight and recovery. Blimey!

We gave a countdown and launched t' Oatlander for t' second time. Blimey! No hesitation from t' launch pad. Ya scallywag! Begad! She started t' arc slightly into t' wind but achieved about t' same altitude as t' day before. This time t' ejection charge blew t' chute out and we had good deployment. Ahoy! She came down a little hot. Avast, me proud beauty! Hit t' ground on one side and cracked a landin' gear leg. Nothin' that a little glue won't fix. Ya scallywag!

Because o' its size, t' flight is really excitin' t' watch and easy to track. Begad!
