| Such a simple and elegant solution!! Thanks! |

| Good to see her fly. 40 seconds sounds amazing. I'm looking forward to doing some rubber powered free flight... |

| Really lovely John. I hope my D.VIII flies as well this. |

| John...IToday, attempted building a Zephyr craft and realized, I cannot see delicate parts, nor assemble them. After 2 hrs. I trashed the plane and await further adventures. |

| Here is a video of one of the first flights. It required very little trimming:

Note that the video is quite large (27M) |

Doing well for the first session with flights around 40 sec. |

| John, you must get some video of this flying, I'd love to see it. Lovely work. |

| "...on gossamer wings..". Lovely!! |

| Thanks. It has actually blown off the work bench once due to passing air currents. It is certainly delicate to hold; however, once it is flying it is quite robust. I have test glided it in the living room and it goes slow enough that it simply bounces off anything it hits. |

| Beautiful work JC. I couldn't do it with these old fingers. It's just too delicate. It's a real work of art. |

| I feel like I need to hold my breath when looking at this plane. It looks so delicate. But a beautiful job. Good work. |

| Now this looks like a scale rubber powered flying lightweight. Excellent craftsmanship. This is art in another dimension! |

The heavy Peck prop, at 3.5 g, account for 1/3 the weight of the model. It also balances the plane without adding nose weight. |
| John Cooper, Image # 6417 | 06 Feb 08 19:28 |
The completed P-6 comes in at 10.3 g (without rubber). Just a little over my target wieght. |

| The P6, with a 16" wingspan, is actually just the right size for Plantraco. If it doesn't fly well with rubber, I will likely convert it to R/C with a Micro9 0.9 g receiver and miniAct actuators. |

| You rebel! |
| jgood, Comment for image # 6400 | 05 Feb 08 10:05 |
| Would love to see these aircraft fly... I see you've done some Plantraco stuff too. I think I might have to try that someday. Keep up posted on this P6! |

| The Vimy has flown, but has had severe longitudinal stability problems. I have made it nose heavy, and increased the stab area, but the problem still persists. |
| jgood, Comment for image # 6400 | 05 Feb 08 08:39 |
| Wow, love that Vimy too. Has that flown? |
| John Cooper, Comment for image # 6400 | 05 Feb 08 08:32 |
| Thanks, the weight of the structure, right now, is about 4g, I am trying to keep the final weight under 10g. The wing is stuck on for good now. It is much easier to allign the struts and weave a needle and thread through it this way. I have also used this technique on biplanes that have top and bottom wing covering, like this one: http://www.scaleflight.net/rc_planes/Vimy.jpg
In this case, only the undersurface of the top wing is covered, when it is attached.
