3D PCBs

I have finally found a very good plugin for generating 3D PCBs. I found it on the Eagle Cad page, this took me to Eagle Up. Its got good directions on installing the plugins, even for me, ha. There is really good support from Jerome, the dude who wrote it, this was really helpful for me. 
Add something to this and you get a complete PCB rendering package. This is done by downloading MaxWell Render for SketchUp, as suggested by Jerome, this gives great results. the two pictures are of my redesign of the Little Wire for single sided home brew PCBs.

My new Plane!!

My new plane is a Fly Cat X-75 delta wing EPO plane. The kit was an ARTF style with ESC and brushless, but I had a lot of fun with the power-train. First the ESC was not working, get replacement, ESC makes smoke signals on bench testing (not even running), I then got a higher spec'ed one from my supplier and finally on the maiden the motor rattles around not cool. 

There is a brief video at the end and in those few seconds of panic I found my plane has a good glide angle and very responsive even when there is no thrust.

The Box...

The contents

Neatly rapped up.

Fuz

Tail feathers

Wing

Launch-grip and landing skid.

Supplied goods 

Together but Not.






Glued up and tagged.


After bench runs, highly under rated ESC

Cooked voltage reg. and 

the control IC's


New !40A! ESC and it works



What it looked like before flight and after.


The funny noise was the loose motor I sorted that out by adding shallow dimples on the lower part of the stator.
