Gmon Posted November 14, 2010 Share Posted November 14, 2010 I have seen this a few times. Different things have fixed it, from adjusting engine throttle cable tension to replacing springs inside the throttle quadrant. I would look at everything from the throttle all the way the to the propeller valve housing. Check the all cable tension, ensure your throttles are passing all pull checks, and inspect all bearings, turnbuckles, rod ends, and bushings. I have seen engine and propellers replaced and the issue continued. Don't be quick to call first thing you find wrong as the fix, take the time to inspect the whole system.

pjvr99 Posted November 17, 2010 Share Posted November 17, 2010 Check for wear on gimbal bearings and bushings, check pressure bulkhead fairleads, check valve housing cover. Quote Link to comment Share on other sites More sharing options...

pjvr99 Posted November 17, 2010 Share Posted November 17, 2010 http://herkybirds.com/showthread.php?1538-Throttle-Creep This problem was previously discussed on this thread ...... in this one case, the loose shaft was spotted by my apprentice. Seems if there is enough bumping around, and you've done every other thing you can possibly think of you have simply removed almost all system resistance, and even that small movement can cause the throttle to creep Quote Link to comment Share on other sites More sharing options...
