I've been struggling to get Plotcalc into Corel 5. I had it in Corel 3. This measures line length like elipses, etc. It makes for design a lot easier. I'm having problems finding a reliable site without viruses. I continue to work.

Hey, Nut.

I've been working on the nose section of the Fury. The intake area is 3.06" sq. The intake area of a 70 mm fan unit is 5.98" sq. Is the fan going to be starved for air? I could probably "cheat" a little without affecting the form. What do you think?

you need a diameter of about 2.5". the fsa of most 70mm fans is about 4.5". when you do fan area, you dont count the spinner area. just make it a 2.5" diameter hole, and well be fine

My 16" micro FJ-1 had issues with a very sensitive elevator. However, these issues may have been caused by the smallness of the model?

Nevertheless, here's some recommendations based on my experiences.

1) Maiden with a well forward cg.
2) Arrange for a small elevator throw mechanically to preserve servo resolution.
3) Use a quality elevator servo.
4) Dial in some expo.

Nut, I have been taking a break from finishing the Skynight and designing the Fury. I designed this and built it within the last couple of weeks. I hope to maiden her next week, weather permitting. Don't worry, I'm getting back on the Fury.

Peace,
Dennis

Sounds great, Nut.

I'm working on the final designs and hope to start making some prototype parts soon.

ok, so i ordered some fan stuff, i think rather than 70mm im going to use 60mm 5 blade fans, ive had great luck with these, and they are super light, and put out about 32oz of thrust, so they will have plenty of pwoer, and decent flight times, plus they are lighter than a 70mm, and, we can use scale inlet/tail pipe sizes!

also, should i make a canopy plug?

That sounds great, Nut. I was a little concerned about the nose (Inlet) I'm starting on because to get the right diameter it may change the overall look. But, you solved this with the 60mm.

Nut, this is the front piece of the nose re-worded for the 60mm fan unit. It has an area of 4.6". Where the 60 mm has an area of 4.38. More than enough air for the intake. Great move on your part.

Here are some pics of the mock-up of the nose. I will be starting the printing next.
