Thanks John. I truly do appreciate your input.
The sight is a county park and I was on a grass field. I pitted and took off from about a 3 foot corridor of concrete between the parking area and the grass. I picked a spot that curved inwards to give my selfe more take off roll room.
Next time out I will have more pitch authority, a fair amount more (may even add some area to the elevator). And more forward CG to eliminate those elevation excursions.
I am darn sure going to hydrate well before going out. I know better, I really do. just did not think of it. I will also take a big thermos of ice water with me. That should help with the dizzies some . I really did set myself up for them.
And I will land sooner.
When I can loop and get inverted that will also help big time.
I can see were a wheel chair can help. But not on the grass and I need to some flight time to get used to this (and not set myself up for the dizzies).
I have decided to abandon my beloved flight box that I have used for many years for RC It has folding legs and folding plane supports. Carries everything and just pain weighs too much. I am going to use several small boxes from here on. My back is so worn out I have no choice. The good news on my back is the steroid injection on the left side has brought the nerve pain down on that side to where I can easily live with it. Now lets get the right side done.
I am thinking of making something like a folding TV tray but taller (maybe as much as belly button high) to work on start on at the field. at the RC fields they have permanent starting stands. Those work a treat.
I am hoping to go out again next Saturday.

I think I have figure out why the plane hunts.
The linkages are ball links and ball swivel links. There is zero play or slop in the linkage. When I hold the bell crank stationary and try to wiggle the elevator, it does not move a bit. But here is the kicker. I can rock on end or the other of the bell crank up and down and the elevator moves a 1/4" or more. It is just a standard nylon bell crank with a nylon bushing, and can wobble a fair amount on the bushing.
I will make a new bell crank from some brass or thin steel stock and solder a bushing in the center and then thru bolt it. Whatever it takes to get rid of the rocking. I think the plane is actually nose heavy, but the elevator hunts up down and so the plane hunts up and down. I have never encountered this before, but I also have never had a totally zero slop linkage before.
So a new bell crank will be the first thing to try in taming this plane.

At least you got it flying Ken, now wringing out the bugs. By the way, I can see why the Ringmaster stunts better than the Ringmaster Junior. Its got a shorter coupled tail moment. The Junior flies more like a stunt trainer. With a newer build of similar size, think I'll have a blast with a latest purchase, the Fox .15X as soon as I get a remote needle to replace the existing bad one. (Want remote so I don't snap it off.
