Some more details.
Some more details about the RC etc...

this is the motor I built:
Due to my slightly inferior winding skills, I only got 7 and 7.5 windings instead of 8.
So I assume around 900kV. Any motor with that kV and no less than 130g mass should do the job.
I think I have some pictures of it at home...
I use a 12x5" Aeronaut Cam Carbon folding prop.
I generally prefer folding props to rigid ones, as they balance better. Both blades come from the same mold, and are thus perfectly identical in shape, weight, and mass distribution.
If that is the case with a rigid prop, depends on the skills of the toolmaker and the injection machine operator.
This setup pulls around 35A from a 3s pack.
I do not quite understand which tubes you mean.
The tube under the pack and the RC stuff, as well as the tail boom and the main poles, are 10x10x1 square tube.
The sail frame has a 10x1 center tube, and 8x1 side tubes.
The upper struts are 8x1, the lower ones 6x1, and the diagonal tube from behind the rear strut attachment point to the front of the sail frame center tube is 6x1 as well.

I am gathering partz 4 the rogallo .
I have a # 11 and # 16 cam. How did u mount the cam almost no vibes except during a dive to loop . Maybe show a picture of installation. LATER captn Don

you are a fast builder!
For the cam, I used a little piece of EPP foam shaped like a wedge with an appropriate angle. I cut a little groove in the top side, so that the side tube of the sail sits in that groove. I fixed the cam with the EPP wedge above it with scotch tape at the end of the tube that sticks out of the sail at the rear.
This way, the cam is pointed right at the "fuselage".

we had a calm evening here, and I used it to program a little elevator mixing. Now I have a 3 position switch, which is either neutral, or has 10% down/12% up elevator mix.
This is quite useful for different wind conditions. Up for no wind, neutral for a little wind, and down to penetrate medium wind better.
As a bonus, I discovered that the "up" position increased my flight time around 20%.

Hello julez, could you put some general pics of your electric rogallo model?. I´m going to try to built it for FPV purposes.
I need to see how you link sail tubes too.
