Default RE: GP Extra 300S - Group Winter Build

Thanks Andrew. I took a closer look at the stick and it is basswood so chaulk up another typo on the inventory list.

Now, the elevator mod. I want to mostly follow what Adrian did except for one thing. The photo is from his post and you can see by extending the elevator up by 1/2", the gap between the two halves has been reduced from 7/8" to 3/8". I want to keep the 7/8" gap. (No one has indicated that the fuse interferes with this reduced gap but I am still worried). One advantage to my approach is that the current config has a 34 deg. opening for the rudder throw. If I extend the gap back to 7/8", this will give me 39 deg. The only down side is that I will have slightly less area in the prop wash region.

Now, by shifting the in-bound side out by 1/4", I lose 1 sq. inch of control area so I will also extend the TE by 1/8".

So to recap, shift hinge line by 1/2", move inbound edge by 1/4", extend TE by 1/8" and add the CB using the existing Hstab vertical brace as the location marker.

That's the plan...now I will build and pst pics when done so hopefully it makes sense.
