Rocket PicBrief:
A small, lightweight 3FNC rocket with an unusual nose cone.

Construction:
Actually, I built 2 Yankee kits; one to replace the initial rocket that disappeared after its third flight. The first kit featured a nice balsa nose cone, but the second kit, while otherwise identical, had a plastic nose cone. But both kits featured a paper body tube, die cut balsa fins, a short piece of elastic, a streamer, and a decal. the quality of components was excellent, except for the shock cord, which was comically short on each kit.

The plastic nose cone was a tight fit, and needed considerable sanding before it would fit. The balsa piece fit nicely but had quite a bit of grain to it. I prefer this to plastic, however. At any rate, it is a straightforward build, and the instructions seemed to be somewhat better than normal Estes fare.

Finishing:
The balsa nose needed considerable filling and sanding to be paintable. The plastic piece was ready to go right from the box, once the shoulder was sanded. I chose to use automotive primer on the original, applying thin coats and sanding in between applications to get rid of the spiral and fin grain. Then I applied some black enamel, followed with a coat of clear to keep the decals on. Unfortunately, this one disappeared soon. The second kit was simply sanded and sprayed with red and black and was considered finished after the decals were applied.

Construction Rating: 4 ½ out of 5

Flight:
Launching with an A8-3 produced a good, straight flight. I followed this with 2 flights on a B6-6, and the last one was never seen again. The subsequent kit was flown on "A" motors only for a while, but I couldn't help trying a C6-7. We lost it too, but fortunately someone in our club found it and brought it to the RSO. It has since been modified for 13mm motors, and does well enough on an A10-3T. I've never had a recovery failure, but if it did, the thing is so light weight it would probably recover just fine.

Recovery:
The supplied shock cord is just too small. After about 6 flights some wear can be seen on the end of the body tube because of the shock cord whipping it. A good thing to do would be to double the cord length, at least. Also, the bottom of the fins are getting crisp, though not quite burnt. Overall, though, this is a great flier.

Flight Rating: 4 ½ out of 5

Summary:
Personally, I prefer the older balsa nose cone, but the plastic one will suffice. Either way, it's a great beginner kit that a kid will have no problem constructing, and will deliver many good flights, so long as you can find it again. But add some length to the shock cord!

Overall Rating: 4 ½ out of 5

GUEST's OPINION:
06/03 - "I loved this kit, and built two. On the second try, I had an inspiration. In my kit, the fins were not precut, and the triangles of scrap cut from the root of the fins were perfect to make strakes just below the nose cone. The addition of the strakes helped very much with stability, and I get perfect, vertical flights with no tendency to nose into the wind." (unknown)

GUEST's OPINION:
03/01 - "The Estes Yankee is a pretty easy kit to build, even for a first-timer. I agree that it is very easy to loose, trust me, I had the same experience. It was my first rocket and all I cared about was how high it goes. So I just started it off with a C6-7. I was very lucky that I found it. It has awesomely straight flights if the fins are aligned properly. It would be better if you use wood glue to glue the fins to the body tube because they will break off in flight with the C6-7's power. My second flight was not so good. First of all, it kind of did a spiral because one of the fins got chipped after a unseen first flight recovery. So the rocket was lost, I think the my nose cone didn't pop loose. I am working on my A.R.V Condor and I will hopefully have better flights on that than what I had on my Yankee." (A.)

10-15-2000 Peter Allen Est SU C6-7 Apogee - Perfect 5-10 mph winds - Beautiful flight on the estes C6-7. Way out of sight but thanks to the tracking smoke and the bright orange streamer,it was spotted at approx. 1000 ft and landed fairly close.
10-15-2000 Peter Allen Est SU C6-7 Apogee - Perfect 5-10 mph winds - Beautiful flight on the estes C6-7. Way out of sight but thanks to the tracking smoke and the bright orange streamer,it was spotted at approx. 1000 ft and landed fairly close.
02-14-2010 John Bishop Est SU A10-3 Didn't See 0-5 mph winds - Excellent flight with a modified 13mm powered Yankee. Fun little bird!
04-03-2010 John Bishop Est SU 1/2A3-4 Apogee - Perfect 0-5 mph winds - Another great flight, best of the day. What a fun rocket this is!
07-10-2001 Les Bradshaw Est SU A8-3 Didn't See 5-10 mph winds - Went up nice and straight. Momentarily lost sight so did not see ejection. Returned nice and gentle about 25' from launch pad.
04-23-2006 Edward Chess Est SU A8-3 Apogee - NC Down 10+ mph winds Event: FVR 04/06
- Shock cord separated, nosecone and streamer eventually recovered, body coresampled with body damage.
07-09-2006 Edward Chess Est SU A8-3 Apogee - Perfect 5-10 mph winds Event: FVR-July-2006
-
07-08-2007 Edward Chess Est SU A8-3 Apogee - Perfect 10+ mph winds Event: FVR-Jul-07
- Very high flight, streamer recovery.
05-17-2009 Edward Chess Est SU A8-3 Apogee - NC Up 5-10 mph winds Event: FVR May Launch
- Could use longer delay.
10-14-2010 Randy Golla Est SU B6-6 None - Unknown 5-10 mph winds RIP - These little rockets rip with any motor. Launched on a B6-6 ejection was heard and it appeared to be at apogee. Drifted into a pond. Had my golden retriever swim in after it :) Recovered and I will re-body it. Status: Scavenged
12-12-2004 Scott Hauff Est SU B6-5 Didn't See 10+ mph winds - Maide voyage race vs. Viking. Yankee is much faster!!!! Airfoil fins made for disapearing act. Never saw until it came through clouds at ~1000ft. 150yd walk. Cant wait to loose on a C6-7!!!! :-)
12-18-2004 Scott Hauff Est SU C6-7 Didn't See 5-10 mph winds - Saw tracking powder then lost it. Found rocket 50 yards away.
12-31-2004 Scott Hauff Est SU C6-7 Apogee - NC Down Gusty RIP - VERY FAST and VERY HIGH. I must have made the replacement streamer a bit too long as it drifted over some trees never to be seen again. Too bad, I have been trying to loose this one for a while!!!! :-) Status: Lost
11-20-2000 Kenneth Johnson Est SU A10-3 SU Just Before 0-5 mph winds - I made an adaptor for 13mm motors. This is the best choice of motor for this rocket, because you can see all the phases of flight.
01-27-2001 Kenneth Johnson Est SU A10-3 Apogee - Perfect 5-10 mph winds - Another predictable, slow, and beautiful flight. A 13mm motor is great in this rocket. Not too high, not too fast, and four flights to a pack.
08-06-2004 Joshua Kaltman Est SU B6-4 Didn't See Calm - Amazing flight! Took off and went up ~1,000 ft. Was unable to see ejection. Took ~1 minute to come back down. Landed 20 ft. from launch pad. Still in perfect condition.
11-12-2005 Conner Kuhns Apo SU D3-7 Didn't See Calm - went out of site and was almost lost and the apogee D3-7 is insane
09-24-2007 Tom Lindsay Est SU B6-4 Apogee - NC Down 10+ mph winds RIP - Fast boost up ejected just nose down wind took it miles and got lost in a collection of trees. Status: Tree/Roof
08-01-2002 MikeyR Est SU 1/2A6-2 Apogee - NC Up 0-5 mph winds Number 1 -
05-25-2010 Jason Orosco Est SU A8-3 Apogee - NC Up 0-5 mph winds - Nice flight
05-25-2010 Jason Orosco Est SU A8-3 Apogee - NC Up 0-5 mph winds - Another good flight.
03-25-2001 Ed Scientist Est SU A8-3 Didn't Record Didn't Record - As an experiment I glued the small pieces from the fins on the top of the BT which resulted in a very unstble rocket.STAND BACK THIS ONE IS DANGEROUSLY OUT OF CONTROL.
04-29-2001 Ed Scientist Est SU A8-3 Didn't Record Didn't Record - STAND BACK! COMPLETELY OUT OF CONTROL. LIFTED OFF INTO AND S-CURVE. A CLASSIC EXAMPLE OF AN USTABLE ROCKET.
05-19-2001 Ed Scientist Est SU A8-3 Didn't Record Didn't Record RIP - Added clay to the nose cone which made the flight even worse I wont be lauching it anymore. Status: Retired
06-21-2000 Andy Sola Est SU C6-7 Didn't See 5-10 mph winds RIP - It flew pretty good, but I think my nose cone didn't pop loose so it is and still is lost! The wind probably blew it far away. Status: Lost
12-30-2006 Gerry Williams Qst SU A6-4 Apogee - Perfect 0-5 mph winds Event: Fiesta Isand, San Diego CA
- MAIDEN FLIGHT: Built from a kit purchased in 1974 (decals rotten, all else fine). Windcocked & corkscrewed for a very amusing flight. Will add nose weight next time, and will NOT use larger engine. :-J
