Should have read the post on not shrinking the stab. Warped pretty good. Prelim test flights were pretty bad, with a steep bank. I've tried unwarping with steam, but it seems to want to return to warped state. |

Finished base layer of tissue. Put on dry with a glue stick as adhesive. Shrunk with 50/50 alcohol & water. Wings came out pretty good, fuse was ok with a few wrinkles, the stab.... |

| Thanks for the comments Lukebozek. The double ribs are according to plans and is intended to provide support for the landing gear. I think I'm going to build the model without the gear, so I probably could have left the second one out. Wasn't sure if the 2nd one was also there for added stiffness though, so that's why I left it. |

| When the tissue is applied and shrunk it doesn't show the formers, instead it leaves a nice smooth shape front to back. |

| What does the scalloping do?

| I like the cowling better than the plastic. |

| Nice work! I see you scalloped around the cockpit. Ate the doubled ribs your modification? Looks great! |

Here I completed scalloping. |

I screwed up the plastic nose cowling trying to fit the prop so I made a new one on my mini lathe. The added weight of the wood cowling helped a lot with balancing the plane. Slipped a bit with the skew but should come out when i sand to size. |

In build #1, the plans called for a single piece wing assembly. The A-1 calls for separate wings glued to the fuselage. Separate wings was definitely easier to attach to the fuse, but I wonder what will happen in the 1st crash. I can foresee some major damage to the fuse. |

here is the side profile of the wingtip |

I wasn't happy with the spar-type wingtps on my first plane, so I wanted to try solid wingtips on build #2. I built up the wingtips with balsa strip, sanded the horizontal/vertical axis to match the surrounding profile, then finished up by sanding to blend the profiles. |

Vertical stabilizer prior to the spars being trimmed. Although not seen in this picture, excess material from the fillets has also been removed. |

Here is the horizontal stabilizer with excess material removed from fillets to try to reduce weight behind the CG. |

Horizontal stabilizer. Not sure if you can see this, but sanded ends of 1/16" spars to match the thickness of the kit parts |

Start of build #2. Applied some lessons learned from build #1 - thinned parts before cutting/popping them out; and sanded open stringer notches with a homemade notched instead of cutting them. |
