Title: Brodak Flying Clown with a TeeDee .049
Post by: Paul Smith on May 28, 2007, 10:21:58 AM: This is a full size Brodak Flying Clown, 200 square inches, as recommended for .09 through .19.

While building my racer, I decided to use some scraps to make lightweight copy for an .049. It weighs 7.7 ounces all-up (less fuel), light by my standard.

I've decided to post this under 1/2A, but I might as well have put it under OTS, Classic, modern, or profile, because I can (and probably will) enter in all those classes. I'd need a muffler for F2b.

On the first & only test flight, it easily did the OTS pattern, including an upside-right landing on some hefty turf. Lap speed is a little fast, 2.7 on 35' lines, maybe 42's next.

What is the fuel tank? Looks like the lid to an aerosol can.

I filled a paciifer with 1.25 ounces of fuel and sized it to that.

The TeeDee is more than enough power. I need to tame it down with longer lines and outthrust. Never give up POWER.

Not much inside...

Keep us posted, and we are having a 1cc/Leprechaun event this Sunday. You could haul home a very nice trophy. (You live where?)

By steering clear of mega-planes, I expect to hit the contest trail this summer in one of my smaller groundcars.

If more modelers would just fly 1/2A, we wouldn't need biodiesel, flexfuel, hybrids, and those magical, energy-for-nothing fuel cells.

Post by: Paul Smith on June 19, 2007, 08:46:16 AM: I was able to find some Bordak 42' lines, add nose weight and slow down the flipper. New weight = 8.0 ounces.

It now does both the OTS and Modern patterns on one 1.25 oz tank.

One nice feature of Stunt Hangar is knowing where any other member lives. Just click on the "Weather" posting on the left edge of their post and it will give you the weather in their home town.

For example: Ray "Minnesotamodeler" is in Saint Paul MN.

Post by: Paul Smith on June 26, 2007, 05:31:32 AM: Thanks, it's the plane.

8 ounces now, including nose weight. I moved the engine forward one boltspace, reduced the flipper travel, and bought some 42' lines.

As you could see, it's still a quick little plane.

With a lot of justification, the big planes attract more attention.

We all have to be impressed with the person who sport-flew his four-engine B-17 two-up with a big scale Mustang.
