Scale RCM 1/3 Scale Champ Build

[Snoopy1]

The gear is never coming out of that plane. And if ever does I don’t think it will be worth while fixing. Nice job

Got a little done this AM, silver brazed the main strut bearing together, a 3/16" piece of plywood is sandwiched between the steel plates and a 3/8" x 3/4" spruced is backed, everything is jointed with 4-40 screws. Everything got painted with epoxy before assembling, the assembly got mated with epoxy and microfiber mixture to the floor and longerons. Once this cures, the rear bearing points will be located and installed.

Looks awesome Tony!

Managed to get the last six landing gear fittings finished tonight after the grandsons went home, mounted the struts on the front fittings, really like the way they work. After looking at various planes on airliners.net decided the Cub tires just would not look right, found these DuBro 5 1/2" pneumatic tires will look much closer to the real thing. tried to order thru local hobby shop but learned they are discontinued, found these on Ebay, two different suppliers. I plan to make aluminum wheel covers.
Hopefully tomorrow morning I will get the rear landing gear fittings installed and install hard mount for the tail wheel. Then the firewall will glued into the final resting place.

Beautiful work!!

 

[TonyHallo]

Got up early today and installed rear fittings and tail wheel mount. The rear fittings also act as the lift strut attachment so it is in tension when flying, the plans showed an additional 3/8" thick piece of wood on top for the 3/8" x 3/8" and 1/4" x 3/8" spruce cross pieces, I thought it was overkill but installed it anyway. The gear was installed and tested before the clamps got the final tightening. Everything moves freely. Now got to go work on the boat, summer will be here before you know it.

Nice work looks good.

 

[BalsaDust]

Those look amazing.

Ran out of work on the boat sooner than I thought, back home at 1300 so got more done this afternoon. Installed the formers on the bottom side, the stringers and firewall are next. Also added gussets to the bottom longerons, these glue on three sides plus grab the cross braces. Finally the plans call for a 3/8" dowel at F5, this dowel is located about 1" below the longerons. While the sides were loose, a 1/8" was drilled through both at the location of the dowel. The 3/8" dowel was center drilled in the lathe and 1/8" dowels were installed to locate and retain the dowel. Might just get to flip it over on Saturday.

The firewall and stringers are in. It is easier to draw the plane than build it. The plans show a nice radius on the stringers with everything else being nice straight lines. There was no way that was happening. To control the bending the straight formers were added in front of the bend, saw cut were made in the stringers to control were the bend was located on the drawing. The saw cuts were packed with epoxy and microfiber mixture, the stringers were installed and glued to the straight formers with thick CA, after the CA cured, the aft sections were clamped into the final position. Took a little fiddling around but everything is straight.
It is the annual steak and lobster fest at the Hallo household today, not much more work going on today. Tomorrow the fuselage will be removed and flipped over so that work on the top can begin.
