I`m using wildcat 20/20, the regulator diafragm seems a little distended but at 4k is ok and transition is good, I will try a new one anyway (thanks wcmorrison)
I`m flying a 3,5kg or 7,7lbs plane (Aerokevlar Panther) and I want more power for vertical lines, and pulling out of torque rolls

Seen posts of people with ys110`s puting 10k+ on a 16x4 or 15x8 is not unususal and is 20% more than mine!

I will change orings too, Any ideas will be well recieved.

Thanks for your help
