Trouble-Shooting pnuematic retracts
Have a set of Robart Airs that worked flawlessly for 2 years. Now they only partially retract or won't drop when time to land and they are out of air when checked on the ground. Have bench tested numerous times and they hold their air for hours and cycle perfectly. :Put the plane in the air and they don't function properly.
My next step is to replace the air valve but anyone with similar experiences, please respond.
Also, I'm not interested in an electric vs. air debate. If that's your game, please start another thread.
Thanks in advance for your reply's.
