If I see air in the lines I pop the cap on the res and pump the handle which actually pulls the air back to the res and out the fill. The tubing tees at the firewall. That's "plastidip" on the handle. Years back I was persuaded to install tow brakes on my Sonerai 2 (similar size, speeds, weight etc) after having flown it for few years with just the single handbrake....a few hours later I pulled them back out...

I like your setup, where is your flap handle? Or do you have electric flaps (Which I believe is the B standard)?

Flaps are electric...switch on the panel. I installed a small indicator for the flaps, you can see it just to the left of the efis.

I have a center stick Model B, what is the preferred option to allow actuation of the brakes from both seats? I've seen the center mount master cylinder, which would be difficult to use with a center stick.

If I had a center stick, I'd put the master throttle and brake lever on the left side. I'd run cable controls under the tank to the right side. Years ago that is what the Sonex factory trainers did for the throttle.
