Nice looking plane,, you're gonna love it.
...... but, although Houston isn't really Dallas area, I too have been playing with a very similar setup to test the Igor Log. Great minds think alike I guess. See the attachment.
I built this a couple of years ago, and due to some health problems, didn't get to test till this year. I had some motor issues also, trying to be too cute by half. Should have put an ST60 on to begin with, but that another story.
The bottom line is that, after flying it for just a little bit, I really began to feel that the Igor Log was real. Smooth rounds and snappy corners that just jump out of nowhere. I'd be interested to get your impressions.
I used a grooved roller bearing in a wire loop like it appears you did. I kept the dimensions of the IgorLog mechanism. I built mine from a Mobest kit (Griffin) and modded it with a longer tail and more tail area. The MoBest wing is an excellent wing to start DIY designs from.
Good Looking Plane ... hope to see you all after the Covid.
