Estes Gauchito

Brief:
T' Estes X-Prize Gauchito is a 1:55 scale model o' Pablo de Leon and Associates' Ansari X-Prize entry. This model flies on 13mm motors up t' 300 feet, me bucko, me bucko, recovers on a 12 inch parachute and has a removable display nozzle assembly.

Construction:
T' kit came packaged in a plastic bag with header card and included t' body tube, me hearties, motor mount tube, ya bilge rat, motor retention hook, me bucko, motor block, retainin' ring, centerin' rings, matey, shock cord, matey, 12 inch pre-assembled plastic parachute, me hearties, launch lug, shiver me timbers, matey, laser cut balsa fin sheet, shiver me timbers, 1 plastic part set that included t' capsule and insert, arrr, display base and nozzles and decals.

T' instructions were typical Estes material containin' lots of illustrations and text and included t' fin markin' guide and shock cord mount.

This is a skill level 1 Beta Series kit. Ahoy! Blimey! Blimey! I found it very easy t' build with no issues. Begad! I started construction by assemblin' t' motor mount assembly as instructed. Aye aye! Blimey! I then sanded t' fin sheet and cut out t' fins. Avast! This laser cut balsa be very easy and great t' work with as t' fins practically fell out of the sheet with very minimal cutting. I stack sanded t' fins t' even up all edges. I cut out t' fin markin' guide and I slightly scuffed up t' surface of the body tube and marked all fin and launch lug lines. I installed t' motor mount inside t' body tube at this time. Ya scallywag! Blimey! After it dried, matey, matey, I attached t' fins one at a time. Begad! While t' fins were drying, arrr, I assembled t' shock cord mount. After t' fins dried, I mounted it into t' open end o' t' body tube. I also assembled t' capsule at this time. I then applied fillets t' t' fins and launch lug t' finish t' assembly. Begad! I now prepped t' model for finishing.

PROs: Easy and quick assembly.

CONs: None.

Finishing:
I started by sandin' t' model smooth and sprayed t' model with Ace brand white primer and sanded betwixt coats. I then sprayed t' body and display nozzle base with gloss white enamel, t' capsule with Testor's copper enamel, and t' display nozzles with Testor's silver enamel. I found it much easier to paint t' nozzles by usin' loops o' maskin' tape t' tape them t' a balsa stick than usin' a paint pen t' paint them in place on t' nozzle base as the instructions suggested. After t' white dried, matey, I chipped off some o' t' white on t' nozzle base and then glued t' nozzles into place on t' nozzle base. Blimey! An optional step be t' spray t' model with clear enamel but I decided t' pass on this step. I then applied t' peel and stick decals t' finish t' model. Overall, ya bilge rat, t' model looked rather cute and surprisingly realistic.

PROs: Easy t' finish, no difficult maskin' required t' achieve t' stock paint scheme.

CONs: None.

Construction Rating: 5 out o' 5

Flight:
T' recommended motors for this kit be t' 1/2A3-2T, me hearties, A3-4T, A10-3T--all 13mm mini motors. Avast, me proud beauty! Blimey! Begad! Blimey! This rocket does require t' use o' recovery waddin' and t' motor hook holds t' motor in place durin' flight, however, shiver me timbers, t' display nozzle unit must be removed t' fly this model.

I prepped t' model by removin' t' nozzle unit t' expose t' motor mount, prepped a 1/2A-2T motor for this flight, added about 4 sheets o' recovery wadding, and packed t' chute into place.

T' model took off slowly but straight and went maybe 75-100 feet up under the 1/2A, deployed t' chute, and recovered safely.

T' next flight was on an A10-3T. Ya scallywag! This be t' motor I'd stick with for this rocket. Aye aye! T' rocket took off straight and quick and went maybe 250-300 feet up, deployed t' chute, me bucko, and returned safely. Begad! Ahoy! Upon recovery, I noticed that the capsule had separated from t' insert. Begad! Luckily, I be able t' find it. You might want t' use CA for this step durin' construction t' keep this from happenin' t' you.

PROs: Very nice and low (100-300 feet) flights.

CONs: None.

Recovery:
This rocket uses a 12 inch parachute which is sized about right for it and there is a markin' for a spill hole on t' chute if you feel that you need the model t' descend faster. T' rubber shock cord held up very well. Even after two flights, I did nay notice any scorchin' on it.

PROs: Recovers nicely under t' stock chute.

CONs: None. Aye aye!

Flight Rating: 5 out o' 5

Summary:
I really liked buildin' and flyin' this nice scale rocket. I found it very easy to build and fly and I be impressed with t' scale detail on it also. Aye aye! I thought t' display nozzle unit on it be a great idea and it made for a nice touch. Avast, me proud beauty! I would highly recommend this kit. Begad! Blimey! I'm sure you could also use a lot of the parts t' clone a Little Joe II as some folks on T' Rocketry Forum have mentioned. Blimey! Ahoy! Blimey! At about $5.79, I felt it was a great value.

Overall Rating: 5 out o' 5

    This modification was my own personal response to what I had seen as an all-too-common statement on model rocket forums: add nose weight. It seemed to me that no matter the situation, the clarion call was for more and more nose weight. "Hey, I painted this rocket blue instead of yellow." "You better add some nose weight." While not usually a kit builder, I found this kit on clearance and decided ...

This is a neat little rocket that flies well, especially on the mini motors. I almost always launch this one first, to give me an idea of how the winds are up off the ground. I was really surprised at how nice it is.

The "Gauchito" is a very accurate reproduction of the concept-rocket designed by DeLeon Technologies for the XPrize contest.- It?s a legacy design, derived from the battered "Little Joe", the rocket designed to test the escape systems for Mercury and Apollo projects.- I have this model, (as a gift from the designer, Mr. Pablo DeLeon) and I'm very proud of it!!!

I bought the Gauchito since it looked rather interesting, a bit like a Little Joe. After purchasing it I also had a contest I was running in Florida for Future Sport Scale, an event where you model and fly a real rocket design that has yet to actually be built and flown. I needed a quick entry for the event so built the Gauchito as my entry. The model was a straight forward build and relatively simple. But since I was going to use it in the contest and it was to be judged for static points I modified the plug in engine nozzles to be permanent in the rocket. This primarily required that I cut away a bit of each nozzle where they would interfere with the mini-engine used to fly it. It did make for a rather tight engine fit but added some points for static judging. It flew fine, as a simple rocket like this should, in the contest. A couple of years later I also used it in a contest in Orlando for spot landing. Being small but low powered it was ideal for such an event, provided the spot was not too far away. It actually took first at the contest!

Anyone have any idea what size body tube this is? It's between BT-56 and BT-60. Could it be BT-58, as sized here?
