Looking good so far. Good choices for kit bashing.
Good luck with it.

To be kit bashed, it would have to have started out as a kit. This is an assemblage of parts never meant to be together. Therefore "Fronkensteen".

I finally received the flaps from Sig. They really harpooned me on this one. I had forgotten how much I hate shaping solid flaps. Then there is the hinge slots. One flap is medium hard wood, the other is just plain hard. I can't find my razor plane.

I'm going to try something different on the controls this time. If it works, I'll describe it here. If it doesn't work out, I'll just delete this post.

This looks like it's going to work. I want to minimize the flap movement in relation to the elevators. I ran one pushrod from the bellcrank to the outer hole of the elevator horn. Then I ran another pushrod from the inner hole of the elevator horn to the outer hole of the flap horn. Movement of the flaps is about what I want. It can still be adjusted later.

I have the color going on now. I need to refine the controls a little, but it will work.

Sounds like it is almost ready. Have my King Sweep ready for test flights, but weather is probably going to keep it grounded til I get to VSC.

I got the covering from Brodak today. The red was a little off, but I finished the covering and drilled the engine mounting holes, which set me back on the finishing. I had to patch the holes for the blind nuts and will have to repaint the nose.

I test flew the Fronkensteen 4 today and decided that it needed a rudder. So, it's back to the drawing board.

I took a short cut in finishing the rudder. I soaked the rudder in thin CA, and after I could breathe again, I sanded it smooth, then applied a coat of polyurethane. Next day, I sanded that smooth and sprayed it with the red. I might fly it again on Thursday. Hope the rudder is enough.

I tried to keep the paint to a minimum. I know it's fuel proof. And then there's the business end.

This thing is stable, but still turns a quick corner. It is too fast with the FP 35, so I will try a different engine.
UPDATE: I removed the FP 35 and installed the 35S ABC. Hopefully it will be a better power match.

After installing a good prop and finding a good setting, the Fronkensteen 4 seems happy with the latest engine. It has very little time on it and will take a while to settle in. I will most likely have to install a smaller tank as now I use 1/2 of a 5 oz syringe of fuel and still fly a while after completing the pattern.

Today I couldn't find a good setting on this thing. It probably needs a lot more running time, but for now, I'll try an OS LA 40 on it.

Phil, I am hesitant to criticize other's planes, so take this as just an old coot's ramblings. I notice in the bottom picture that the bend angle on the upper end of the landing gear is not parallel with the thrust line. It should be. The angle which appears in the picture would tend to make the plane be extra sansitive going into inside turns and a bit lazy going into outsides. That is unless you trim a considerable amount of down into the elevators. I would (to keep the wheel location) move the top of the gear as far forward as the tank would permit while keeping the wheel location the same position. Try to get the bend angle as close to parallel with the thrust line as possible. If you need a better description you might give me a call or direct E-Mail.

That doesn't seem to be what's happening here. This is the stock fuselage and gear from the Brodak Cardinal. It seems a little too sensitive in both directions. I also can't keep the speed stable.

The last crash damaged the fuselage under the landing gear mount. It seems this is a weak point on the ARF Cardinal fuselage. The rudder was damaged again, not much of a surprise. I already have a replacement ready to install. As far as the reason for the crash, when you slow the airspeed down, it shows up problems masked by the higher airspeed. when I tried to go inverted with low airspeed, the outboard tip came up and it came in on the lines. I'd guess not enough tip weight. Now to get to work. Attachments:
