Hi Randy,
Here is a link to a thread in 2004 with pictures of how I did the flaps on the first production kit from PCM. I am still flying it regularly.
There is no exposed linkage or control horn. I used a servo mount from Dreamworks called servo pro.

I have a mold available for a custom fuel tank that holds almost 1.5 gallons of fuel and uses up all the available space in the fuse.
The DV8R flys great with it full and I get 10 minutes with the hammer down the whole time on my p-120 with ample reserve.

I have pictures if interested..

Let me know if you have any questions.
