It's there when the servos are half way on their travel. John needs to add his own receiver and tune it. I prefer to use the adjusters on the pushrods, my wire bending skills are not accurate enough for the way Josh does it in thier builds
I also got me some black FB recently (it's actually slightly lighter than the white one I use). Gonna make the cockpit on the Sbach out of it, then maybe use more of it for the next project... Looks very nice.
I know what you mean about those Bixler Bends. I once feared them as well. You should learn to embrace them. Learn to think holistically. By that I mean, get as close as you can, utilizing the final control horn and servo placement as a rough adjustment. Then use your transmitter configuration to adjust the sub trim for fine adjustment. Seems to work well.
the bends themselves are easy... it's getting them at the right place... doing them on lower throw builds makes a lot of sense... trimming it up doesn't effect the end points for max throw... I have done some, and on other builds I've done the U shaped bend on the rod to adjust it...
I'm still very much a learner myself. This wing scared me initially and I got a very experienced pilot to maiden it. He trimmed it and enjoyed the wide range of flight performance this design has which gave me confidence in my build.
Next flight I got him to launch and land it and I had a fly in-between.
Now I do the whole flight and to be honest, this plane is very docile and forgiving, don't even know why I was so scared of it.
A first plane it isn't, you have to hand launch it and that takes a bit of practice but I would recommend it as a second plane.
Its a BMFA thing. The UK equivalent of the AMA in the US. There are various standards you can achieve which are recognised by all affiliated clubs. So if I go to another club flying field they will want a minimum of an A certificate to allow me to fly there without an instructor/support. http://achievements.bmfa.org/the-tests
