    Scale Wendell Hostetler 30% PA-28 Cherokee Build

    If I can do it in OpenTX in will not require any additional hardware switches and thought. When the flaps are deployed will act as the gear down command and eanble the servo. I'm thinking gear up command will be some value of the x axis acceleration along with throttle opening and time...

    Never used Kevlar, how does it wet out? Think my next build might be a fiberglass fuselage layup and was considering Kevlar fabric.

    I would like to do it without using another switch and one more thing to think about. SA -Flaps, SB - Ignition, SC - Rates, SD - Stabilizer, SF - Choke, SG - Stabilizer, SH - Lights. I can put the gear down function when the flaps are deployed, thinking of using a greater than on the throttle...

    I seen this on YouTube and thought I might try it on the the Cherokee, Assan AG61 anti slip nose wheel gyro. It has two inputs, rudder and gear so when the gear is up it shuts the nose wheel servo off. Thinking how I might do this in OpenTX. Thinking using the flap function but I don't always...

    Have the exhaust worked out. The tubing is high temperature silicon from McMaster Carr. Weight came at 29 pounds and the CG is spot on. Need to mount the throttle, choke and nosewheel servos and make new linkage. Getting closer.

    I have engine mounted, need to hook up the servos and exhaust then do another weight and balance check. The carburetor kit arrived, after seven years use, the inside was pristine, put a new diaphragm and pump side diaphragm in.

    This is what I came up with to stand the fuselage on the tail. Making standoffs for the new engine.

    Chuck the bar, make a 45 degree cut about half of the radius of the bar, then finish round with a file. Make the round end as your first operation.

    Scale Wendell Hostetler 30% PA-28 Cherokee Build

    It wasn't so much the weight of the but tail weight would have been needed in addition to relocating the throttle, choke and nosewheel servos. It was going to get heavy. Falcon offers a 4" and 4 1/2" spinner, I would think 4" would work just fine.

    The kitchen scales arrived and after an exhaustive study have determined that the Roto 85FS has got to go. I tested the scales with a 6 pound weight and each scale reported the weight within .002 pounds of each other, close enough. The plans show a Zenoah G38, happen to have one and it tips...

    Here are the ends of the struts on the BUSA Super Cub I built some time ago. I don't remember for sure but I think the brass pins are peened to hold in place, I would image these were assembled with epoxy as well. The date of the photo is 2007, might just finish it someday? Photo quality is...

    Thanks Mike. The 3 1/2" white spinner is from Falcon Props, carbon fiber and very lite weight. Found and old 26" x 10" Mejzilk prop in my stash, I bet I had it for over 15 years, cut it down to 25" and fit the spinner to it. Only minor sanding was required, drilled for the Roto prop bolt...
