i will verify the incidencse on all surfaces... but the plane flew almost perfect. I believe I added 3 clicks of up elevator in my trim, and one click left. virtually no subtrim.
there is zero mix in the radio
no visible or measurable damage to the plane or warping
I'm running 50% expo on high rates... and that gets pretty close to 45 degree deflection. but Ido not have to be on high rates for the pitch and roll to occur.
I'll need to look more into this lateral balance... I have never done that on any plane I have owned.
hinges were sealed crappy with scotch tap... will be re sealing them with clear monocote very soon.
I did find an interesting problem last night when really looking closely at it.. and the top two higes on the rudder actually seem loose... there is a tiny bit of play up there that Inever noticed before.
the elevator is connected with carbon fiber... but the elevators are able to move in opposite directions... it is not stiff by any means. so I have to believe this plane was ment to have 2 elevator servo's
i wll be putting in new hitec 985's in the ailerons as well
Iwill try and get a video as soon as possible...
the other interesting thing.. and maybe its just getting used to a different airplane... but I was doing a flat spin and everytime I want to come out of it it wants to drop to the right and do one extra roll/spin on the way out than what I am expecting it to do.
thanks for all the inpur nitro... im going to figure out exactly where the cg on this plane is supposed to be...

Its best to start from the basics.
Check the incidences on all surfaces, -+ 1 degree will make trim problems.
Is the plane trimmed OK or did you have to add excessive subtrim to any surface?
Are the ailerons/elevators centered when trimmed for flight or have added mix or trim to correct neutral flying?
Check the wings, ailerons, stab and fuse for any twist or washout created from storage or repairs or temp changes. Make sure all is squared off and measure twice.
Check that no mix was added in the radio, where elevator may activate some rudder deflection.
With big deflections. 40-60% or more expo is ideal.
Do lateral balance, many skip this step, it will matter.
Seal the hinge gaps.
Once the above is satifactory, only then play with the CG, often 1/4 or 1/2 inch shifts will make very noticable changes for the good or worse.
Often just little things can make huge improvements, cover as much as possible.
Load test the ailerons too.
Having the elevator connected on 2 servos is a potential problem.
I would be inclined to split them completely.
Make sure the hinges are not pulling out anywhere.
Can you post a vid of deflections on ground and a quick in flight outcome of the snap?
