Yes, my plane has similar traits. I have attached a picture of the “new” kit aileron seal and a rubber bellows which I think will fix the problem. I have purchased the bellows but have not got around to installing them. A lot of IV-P drivers with the new flat plate sliding seal have complained about high aileron stick force.

I just purchased a 4P
It only has 120 hours on it, so still in the debugging stage
I took it up 10000 feet and when I pressured it the ailerons got really
heave and stiff that even the auto pilot would not control it
While descending the Controlls became gradually lighter and normal
Anybody had the same experience?
