We did some more planning and prep for installation of the autopilot servos. We plan on tying into the bell-crank (for the push-pull tube) to control the elevator. Below is a picture of Michael who is working on installation of the mounting plate for the servo.

We also did more planning for installation of the autopilot servo that will control of the ailerons. We had heard that other builders had mixed success with autopilot control of the ailerons... but we already had purchased the servo, so we figured we might as well install it and see how well it works for us. The method of installation we plan on using is based on another builder who put the info out on the Wings Forum. We will add a second pulley underneath the front two aileron pulleys, and run a secondary cable to a capstan servo to control the ailerons. We are currently still in the planning phase, but I put together a quick mock-up, running orange string instead of cable to make sure everything worked and all the clearances are good. Below is a picture with everything clamped loosely in place... but it looks good so now we will have to build the mount and make it all work. Actually have to buy some more aluminum to make the mount.

Also ran into a bit of a setback with the installation of a fitting for the vent line. The fitting we purchased WOULD have worked great... except it requires access from the inside of the tank. But I forgot to account for the fact that there are 3 permanent baffles in the tank, so there's no way of getting to the inside edge of the tank (where the vent will be) from the top fuel cap access hole. So now onto plan B. We plan on screwing in and epoxying a fitting from the outside. A new fitting was ordered, and that will be installed in the not too distant future.
