The Yak 15 breaks down very compactly for storage and transport. |

Ready for wing cover. The remaining structure is complete except for balance weight. |
| simpleflyer, Image # 19505 | 01 Oct 10 21:22 |
Wings completed and ready for joining and forming the dihedral. The center section is the sliding wing joint which allows the wing to be removeable. |

| With a little luck, Richard, it will be flying next week. |
| simpleflyer, Image # 19464 | 28 Sep 10 21:44 |
Patterns cut out. Fuselage and tail sheetwood kitted. Wing plan drawn. |

| I look forward to seeing this. |

We came upon this 3-vu of the Yak 15 that all but jumped off the page asking to be built as a profile 'swinger'. So we scaled it up to a 14 inch wingspan and copied it to a piece of manila card stock. Did some figuring on the cardstock to find out how much to enlarge the horizontal tail and drew in some lines for alignment and placement of the flying surfaces and a few other tweaks. Next is to cut out the patterns and trace them and begin cutting balsa. |

| Thanks, Phil, for your comments. I fly in a small area of about 100 feet on each side with some obstructions. So my flight radius is about 35 feet max. For long line flights, I use a two piece cane fishing pole of ten feet length. This length allows me to extend all the needed line prior to launch. If I'm flying with 25 feet of line or less, I just raise the pole vertically above my head and play out the needed line and go from there. If I need 30 or more feet of line, I extend the needed line and place it on the ground carefully so it won't tangle. Then grab a few feet of line with the model and swing it around to get it going and release it and let it fly out to the outer edge of the flight circle before swinging it with the pole. However, on longer flights, I can see where it would be and advantage to start out on a shorter line and extend it while flying. Some have used a pole with a reel attached for this purpose.
Re, model weight in relation to max radius of flight circle. I guess that this would be a concern for large models on long lines. For my relatively small model and small flight area it is a very minor concern. More important is to have a model with good design proportions and that likes to fly as a small model. Also important is a good sturdy design. By the time I have beefed up a model to survive heavy use and variable flight conditions, it is plenty heavy to fly well in our compact flying area.
BTW, we've an on-going discussion on swing control in the controline section of the Small Flying Arts Forum. You're welcome to join us there for more information.

| Hello simpleflyer. To get these going do you just start them with short line, then just slowly let out the length? And am I correct (or not) in assuming that the weight of the model and the drag and weight of the line dictate the maximum radius that one can fly these around at? I remember your Javelin. Looked pretty high up there. They look like a blast and a couple (or few) might be in order for my family. Myself included! Thanks. Phil |

Close-up of the model in flight. Scratch built Guillows no-cal model produced in the early 1950's. 8 1/8 inches wingspan. |

| So simply graceful in its own right........... |
| simpleflyer, Image # 10735 | 01 Feb 09 20:05 |
The wing was readily attached and the Stinson flys OK. Sticks on the wings are for gaging the alignment. |
| simpleflyer, Image # 10734 | 01 Feb 09 20:03 |
But the Stinson is still able to fly. Don't try this with models other than controline. |
| simpleflyer, Image # 10733 | 01 Feb 09 20:00 |
Not all flights are successful. Here the outboard wing seperated from the fuselage. |
| simpleflyer, Image # 10732 | 01 Feb 09 19:57 |
A couple of days later, we were lucky to snap this. |
| simpleflyer, Image # 10731 | 01 Feb 09 19:55 |
About a month ago, we modified the Stinson for swing control flight. Last week we had some great flying weather and snapped this. |

| Glad that you enjoyed these. We built a few of them as a youngster,also: The F4U, B-36, Mig 15, C-119(had a ride in one as CAP cadet in 1957), and F-84 which I didn't get a chance to finish building. Due to the interest in these little Guillows models I will try to upload some of the plansheets to a Yahoo group that I moderate. Stay tuned. Al |

| Boy, those are oldies to say the least...........
Ummm...if you are already copying the plans, can I get a set of each? |
| jerry campbell, Comment for image # 9059 | 10 Aug 08 07:43 |
| I built a lot of them and played with them. I had a camoflaged AVG airfield in my dad's strawberry patch. I must have had at least a half dozen P-40s when a dime was like a dollar. Boy does this ad bring back memories. |
