an idea of how thick the tow was before the cya?

I really don't know how to answer you.
I used some prepreg for the first hub that I reinforced and that's very thin. Prepreg is no longer available.
I would guess that the tow was about the thickness of a few layers of paper.

thanks. that is good enough.

i asked because as i have been using cf that comes as weave (like cloth with layers at 90 degrees) i have got strips that come loose at the edges, and have been considering using them for this purpose, as they seem to me as the ideal material for the purpose. the good thing is that they come with the grain oriented in 1 direction, and remain together, are easier to handle, which is not the case with tow.
will try them and tell.
thanks again.

For those who want another alternative to the stock props and hubs, Hobbyking sells an 50mm Alloy Folding Propeller Spinner with 4mm, 5mm & 6mm Shaft adapters and a set of TGS 10x6 folding props that work for the Radian. You would not believe how quiet this setup is, compared to the stock hub.
The downside is the weight. This setup is just over an ounce (30 gms) heavier than stock.
Others have posted lighter alternatives.

So I attached a GoPro to my radian, the 2m BNF version. Made a lightweight balsa and foam cushion mount to go on the fuse above the wings right at the CG point. Didnt want to do the cutting into the fuse mod because I'll be taking off the mount later on.

I went from an average of 45minute flight times to 5-15 minutes depending on wind conditions, with the GoPro mounted. Not happy about this. The footage turned out great though. Obviously the extra weight and drag is forcing me to use more power. How do you guys get around this problem? Has anyone attempted to add winglets to the GoPro casing to give it a little lift to help with the weight?

I use a Mobius cam, much smaller front cross section and lighter, maybe less picture quality, but fine for me.

Probably no way to get around it other than finding some good thermals or flying at a slope soaring site.

I had a SJ4000 mounted on one of my gliders and it just caused too much turbulence so 1 flight was enough.
I now use my Raptor twin for video instead.

I use my Mobius on my Radian without any issues and for some reason I swear my Radian flies better with the Mobius attached to it.

How do you attach it to your Radian?

Velcro and one of these camera mounts on the left.

My Radian arrived today! I have been reading this thread but I am only up to page 825! So I thought I would jump to the end and ask two questions.

1. Are there any mods I should make since I am just starting to assemble the plane? Because of the weather and my schedule I will not be able to make the maiden flight until Friday at the earliest. So I have time to do any mods that are recommended.

2. What do people feel about putting the rudder on the right stick? I flew a friend's Radian last weekend and he has the rudder on the right stick.

Thanks!

check that the movement is smooth on the servos and push rods.

I would put heavy duty scotch packing tape along the wing's leading edge.

Yes the rudder on the right stick, or otherwise , using a mix, on both left and right !

Check the CG.

do a few un-powered glide tests to do a preliminary trim ( on a plush lawn or sports field)

don't hand launch at more than 3/4 throttle.

Check radiocarbonart.com . Paul Naton has a lengthy video on mods/improvements to the Radian.

Maybe this helps? I fly my Radian with GoPro and Mobius all the time and although performance is affected it still thermals very nicely on good days. Depending on conditions I use 1300-1800 3S batteries and everything is stock.
