Default RE: Dirty Birdy Build Thread

<xml>This winter I bought a DB-60 kit from BlueJay, and finally did the maidenflight yesterday. It flies supper nice. I consider myself still a beginner and I was able to land this airplane with a very nice long roll.I'm very happy about it.

Completing the kit was a little bit of a challenge for me, since the wood, the plans and the instructions did not always make sense in the first read. I had to take my time, think it over and re-read the instructions, and in a few instances go my own way.

Some tips (which might be obvious to some, but were not to me):
- Measuring my OS-60 engine and the plans, I decided to move the firewall back about 1/4 inch to allow for the prop to end up in the same place, and not needing longer fuselage sides.
- I used a different nose gear than what was delivered in the kit: I used a taller one to keep the 11x7 prop off the grass, and also used 3" wheels for main gear. Looks a little big, but gives nice clearance.
</xml>- Ikept the control horn on the steerable nose gear inside the fusefale, but to get that working had to hollow out the bottom nose block and the side support block. You have to play wiith this before you final glue these pieces or else it's very hard to get to.
<xml>- Even with the battery pack tight against bulkhead #3, I still needed a lot of dead weight in the tail. I found this out after covering. If I had balanced it before, I would have created a battery compartment further back in the fuselage. If you need weight, it might as well be the battery.
- The plans and instructions did not mention throws. Lynn from BlueJay suggested 5/16" for ailerons, 3/8" for elevator and 1 3/4" rudder. Somewhere else I found 3/8" for ailerons, 5/8" for elevator, 1" for rudder. So I set my dual rates around these values. With my limited skills I was able to keep it under control on high throws. Once I get more familiar with it, I might turn it up a notch.
- To give the canope something to hold on to, Iglued pieces if 1/8"x1/8" balsa on top of the fuselage.
