I try tyo come up with a good colour scheme and then find that I don't have the colours that I want. In the end I finish up with a bit of a mess..

This is going to be a sort of red, white and blue scheme.

What film are you using after the loss of solarfilm ? I have gone for the hobby king stuff , goes on ok just needs a bit more heat not tried oracover yet though as it's a bit more expensive.

Yes, I actually like the Hobbyking material. I always uses Supershrink Polyester which needed (or would accept) full heat of the iron.

It is also a very civilised price. Only thing is that not all the colours are available all the time. I can live with that.

Well I got the model finished and today was perfect for test flying.

Unfortunately nd for some reason it was actually over powered abit and strangley over sensitive to the controls. The CG was spot on but itb took off kike a scalded kcat and headed for the sky. A slightly hurried application of down elevator from about 5 feet and it dived and hit the ground. No serious damage but it did end test flying for the day.

And to think that I had considered taking a spare model but as I had not plenned to be on the field as long as usual I didn't.

Repairs will not take much more than a morning.

That's a pity with a new model - we all know the feeling! Doubtless you will have it all sorted out soon.

A simple but effective scheme, very nice. shame the flight was cut short but no matter, I am sure it will perform. The swept fin is very racy. cool

I must admit I was surprised at what happened but it will not take long to repair.

Nice looking model Peter 👍 sounds like the CG moved back for some reason it's always annoying when this happens on the first flight 😦. Have you any idea what the cause may be ?

In the photo it looks like there is a bit of up elevator?

There wos a touch of up elevator but when I corrected it went down much harder than I would expect.. The symptoms of a rearward CG I agree. Elevator control throws at low rates are 1/4" each way.

Next time I will reduce throws and also reduce the power by using a smaller prop and allow it to gain more height before correcting.

I have now solved the problem pf why it dived into the ground. It was basically a total idiot called Peter MIller.

My only excuse is that I have been having problems with a mains water leak, a semi blocked sewer and a pigeon stucj half way down my chimney for four days. As a result I have been stressed out and tired out

When I set the controls up the elevator servo must have been out of line and even though the control directions were independantly checked on the field no one noticed what I should have seen at home, at neutral elevator stick I actually had half down elevator.

As I have saind many times "I can't help it if I am thick!!!"

Good to hear you have found the cause it's easy to get distracted when other things are going wrong 😨 . We had to get wire covers put on our chimneys after a magpie decided to pay a visit , ended up with bird plus a load of soot in the living room 😈

It can happen to anybody Peter! I had noticed that your static shot showed some down elevator while the inflight shot showed some up which made me wonder if the elevator was reversed or perhaps jamming.

I console myself with the thought that Roy Chadwick, designer of the Avro Tudor was killed in one which took of with the aileron controls reversed.

Now that takes some doing!!

moon dancer 2  3.jpgWell yesterday was perfect and I was able to fly Moon Dancer 2 and getthe flying shots.

It is highly aerobatic and I flew the usual aerobatics plus my square loops and four point rolls.

It really needs a slightly larger rudder to fly sustained knife edge but I am happy with it as it is.
