Re thinking completed.

After not being able to get two engines to run properly on the Little Red Plane, two Flite Streaks and the latest crash, I salvaged the hardware and designed another plane. It's a bit larger with a better airfoil and a full fuselage instead of a profile fuselage. I'm counting on vibration being the cause of the bad engine runs. The full fuselage is more solid and stiff. I ended up sheeting the wing with 1/32 balsa and covering it with polyspan. Sanding open bays is very challanging. I covered the fuselage with paper used by doctors on exam tables as the old standby silkspan is no longer available. It wasn't pretty and I had to do a lot of sanding and filling. Anyway I got the plane almost ready for paint before final assembly. I'm hoping that will reduce banging the assembled plane on tables and lights during the paint process. Plus I'm finding things to do that should be done before final assembly.

The clear coat continues.

After asking how long should I wait to final sand I backed that up by going to Youtube. Everyones advise seemed to mesh so I sanded. I bought some polish used on Youtube and put my buffer to work. It came out quite well. After doing this for 70+ years I finally got a shiney paint job. I had shortened the nose 3/4 inch as the plans I used to build were not quite correct. I re installed the engine and got in a few short flights. It flys better than before. I had to install a larger fuel tank and changed engines while I was at it. The one that was in spewed a lot of oil. I test flew that combination with good results. I should mention that I put a pallet across the ditch I have to cross to get to the field. When I had the plane for the first test flight the pallet slipped on the muddy ground when I stepped on it. Somehow I didn't fall with the plane and field box but the stabilizer got damaged. I had to replace several ribs and re cover the damaged area. All is well. A few weeks ago I flew the little red plane at my sons yard. I pulled up into a half loop to go inverted and the wing tip hit a limb. That caused a violent yaw which broke the fuselage causing a crash. I glued it back together and get in several flights here. Yesterday I was flying it and the engine went wild. I did some loops up high and the motor quit but the lines went slack. Then the engien re started and drove the plane into the ground. The fuselage broke in the same place again. I must re think this project.

Some repairs and a clear coat.

I took the small red plane tomy sons and gotin a flight. The engine went crazy right after lift off as it has been doing. It's still flyable so I did a half loop to inverted. Except I clipped a branch and the fuselage broke just behind the flaps. It was a reasonably clean breaak so I saved it. I fit the pieces together and put some super glue on then scabbed some 1/64 ply over the breaks. I installed the Os FP .20 and a new tank and the right size venturi. It had a .282 in it. Then I swapped the metal back plate to my LA .25 and the plastic back plate with needle valve assembly to the .20. I flew it this morning and it ran very well and flew very well also. On Monday I got the Spray Max 2K clear coat. The next day was dry and warm so I hosed 3 coats on the Legacy 40. I also did a quick clear coat on my Dodge headlights. I just found out that I should wait 7 days before sanding and buffing and I should use 2000 grit paper.
