    Scale PJ 295 build.

    I have read several times to build the second side on top of the first to get two identical sides, I've done it once or twice. Since I normally have the plans for some time before building I see little chance that the plans will change due to humidity changes. Pretty sure this is your case! As...

    Scale RCM 1/3 Scale Champ Build

    I have a Morse 3 taper collet holder that I use, really need a face mounted collet holder so that material can pass thru the spindle.

    Scale RCM 1/3 Scale Champ Build

    Been working on the new gear struts when I get a chance in between my daughter's bathroom remodel and the holidays. The gear is 3/4" longer and I used .035" wall 4130 tube rather than the .065" wall on the original. Also working to minimize the size of steel parts to save weight. Used my...

    Scale Nelitz 1/3 scale Cub build

    OK I get it. I'm guessing you set the wing to zero by changing the angle of the fuselage then set to stab to zero?

    Scale Nelitz 1/3 scale Cub build

    Draw a line on the plans from the center of the leading edge to the center of the trailing edge. Measure down to the end points to the center of thrust. Use the difference divided by root length and take the arctan of that number, that is the wing incidence as measured by the Robart incidence...

    Scale Nelitz 1/3 scale Cub build

    The plans for the Cherokee are still hanging in my shop. I had a look and the incidence is shown at 1.7 degrees positive. The airfoil is a semi symmetrical foil. I looked over the BUSA plans and instruction manual and did not find any mention of the incidence because the incidence is set with...

    Scale Nelitz 1/3 scale Cub build

    Coming along nicely. I'm surprised the flat bottom wing as set at zero? I'm thinking more like +1 1/2 degrees.

    Probably not to code, needed a shorter flange for my daughter's bathroom remodel. Got to work in the shop anyway!

    Scale Nelitz 1/3 scale Cub build

    I built many planes with a 5" band saw and a drill press. I find the band saw more useful than a scroll saw, I think the only time I use mine is to put holes in formers.

    Scale RCM 1/3 Scale Champ Build

    Well I in the past I used a single X8R with some type of Power Expander. The Champ was the first plane where I decided to use a redundant setup. The redundant setup allows for antenna diversity. I did have a few flight where the RSSI was critical when using a M+ receiver for the redundant...

    Scale RCM 1/3 Scale Champ Build

    I weighted the fuselage before and after the covering was removed. The total weight of covering and paint was 1.32 pounds, hopefully I can improve here as well. Once the covering was removed you are left with the gummy Ekobond glue. During the build I found that an eraser could be used to...

    Scale RCM 1/3 Scale Champ Build

    Doing a little revamp on the Champ. Removed the fabric on the fuselage to replace the landing gear brackets. The brackets were just too long. See phot of full scale and model below. I bent the right side brackets last year when I stalled during landing. I had a dead stick this year when I...

    Scale Nelitz 1/3 scale Cub build

    I just did some calculations based on 1220 pound gross weight full scale Cub, the lift struts are carrying 1080 pounds of the lift force while the center bolts are carrying the remaining 160 pounds of lift. Of course this is at level flight. There is also a compressive force on each spar of...

    Scale Nelitz 1/3 scale Cub build

    Look here. The structure is formed by the center support, wing spar, and lift struts, the rest of the structure in the cabin area is window dressing.

    The 'What did you do in your workshop tonight?' thread

    That's looking real nice. I had a job over the weekend where a larger lathe was in order, was thinking about your lathe while the part was spinning. Had to remove the DRO to make the part fit.

    The 'What did you do in your workshop tonight?' thread

    I went out on Saturday, 15 MPH winds, Weather.com said 7 MPH when I checked in the morning. Had to fly anyway after driving a hour to the field. On the second flight I hit a hole in the runway made from skunks feasting on grubs. Stopped the plane dead and bent the landing gear back. Can't...
