    ​ The wings are just about complete.Didn’t realize I was short 2 servo arms for the savox servos. Ordered them last night so should not be much longer now.

    Got a little done this week. Motor is mounted headers and cans in and throttle servo in and hooked up to carb. Rudder servos installed and linked together ready to attach pull/pull cables.
    EQ 6 Turbo Smart-Fly mounted and IBE is hooked up and LED and pin switch mounted on side of fuse. McFueler mounted on other side

    Oh and it finally has a landing gear so it's now off the building table and on the walk around set up bench.

    I have always supported cans and pipes with 2 supports. Eliminates some exhaust vibration that using 1 mount can't do.
    Do what works for you, this is what I do. I have seen headers break so I do not use it as a support.

    Should the cans always be supported in two spots or can one spot be used assuming header holds the other end?

    While the cowl filler is drying I going to get a little ahead to the equipment install

    Installing the headers and canister mufflers I am using knuckle headers from DA. The drop measured on this airframe using 2 canister mounts centered in the allotted space in the tunnel was 80 mm. The standards are 25mm, 50mm, 60mm, 70mm, and 90mm drop. So using knuckle headers was the better choice to achieve a 80mm drop.
