The building season in spades.

I have one plane that is the best flying plane I have. I just the other day started to build another using the original as templates. I ordered parts from Brodak and got some balsa from the hobby shop and started building. I need the rib set from Brodak and the motor mounts to get the fuselage started. I have the fuselage sides cut out. I managed to build the stab/elev unit and get them sanded to shape. Yesterday I scored a Legacy 40 kit with the string attached that I frame up another kit in payment. I've already built one of the freeby and I'm using the same wing on my second copy plane. I should pick up the kits tomorrow so I can use the rib from that kit to mark out it's placement on the new planes sides and continue the build.

Some progress.

After several test flights and trim adjustments I felt confident enough to fly the whole pattern with the Go Devil. That led to even more trim changes. The landings needed fixing so I moved the landing gear aft about an inch. I reduced the effectiveness of the flaps and got more down authority from the elevator. I think the flaps were disturbing the air going over the elevator. That was the biggest problem with the plane. I changed the stock muffler for one that is a half ounce lighter. I have a lot of adjustability in the balance of the plane. I just have to find the right combination. Now with the time change I have more early morning calm air to test in.

Another Old Time Stunt Plane.

This one was given to me and the wing was built and covered. I had to get some plans in order to build the fuselage. The weather has been dry lately so I got the spray gun out and gave it a base coat of white. Then I found some left over paint from the El Camino and it proved to be compatible with dope paint. I used that for the red trim. I got it assembled this morning after spraying the clear. Total weight is 48.6 ounces with a 600 square wing area so things should be good. I had to use a 2 ounce heavy hub and the stock muffler to get the balance right. That is 5 ounces extra. Plus 1.5 ounces of tip weight. Back when it was first designed the engines were a lot heavier and didn't need extra weight.
