It depends on how well the plane lands. Some planes have a tendency to bounce after landing. I this case I set a slight ammount of drag on the brakes which is mixed to speed brake. I set the air pressure in the separate retract air tank low enough to make sure the brakes don't lock up. By the way due to the lower air pressure you may need a larger air tank.

Also some airvalves need high pressure to operate properly so heads up!

I had good luck using low pressure (30-40 psig) with ultraprecission and Trim brake valves.

If your turbine has a pressure fitting hook it up into the brake tank then you never run out. Make sure you instal a check valve between the turbine and the air tank.
Good luck

That will work but you won't get much pressure at idle and only 20 psi for a 12 lb thrust type motor and maybe up to 30 lbs for a larger motor at full power.
