Using a Jet-Tronic valve on a set of CJM trike retracts...................works perfectly.

When I turn the radio off after a flight, I get a 'ppsssttt' as the valve seems to vent the pressure from the lines & cylinders............though the air bottle pressure is not effected. On a couple of occasions when pushing the model over bumpy ground back in the pits, I've knocked one main leg off it's locks and it's gone down on a wingtip.

Is this venting of air normal ??..................I've checked it with gear in the up position as well, then turned off, and it still vents. My ATV's (MC 16/20 radio) are set to 100/100%.....................have I done something wrong, missed something in the set up, or is this normal ??.....................it's not much fun carrying a 30lb model back to the pits every time after a flight !!

Thanks in advance.
