Pete B Posted July 16, 2010 Share Posted July 16, 2010 The heading just about says it all Switched the Tx on tonight and found that the aileron trim only works when moved to starboard - zilch to port. Not being overly familiar with electronics, what is the most likely problem - a dead switch or perhaps it just needs cleaning? If there's half a chance I can effect my own repair, I'd like to try as servicing here in France is about two armfuls (and half a leg) of blood............ Advice gratefully received as usual, ta!

Tim Mackey Posted July 16, 2010 Share Posted July 16, 2010 Its more likely to be a slider potentiometer, or a mechanical lever which moves the actual gimbal potentiometer. - unless they are digital trims. Sorry dont know the Tx .If its a digital trim, then yes its a switch, and could be either duff, or simply need cleaning with switch cleaner aerosol...or maybe a broken wire?

Pete B Posted July 16, 2010 Author Share Posted July 16, 2010 Ta, Timbo - I'm going in now, if I'm not back in an hour, send out a search party.............. Pete Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted July 16, 2010 Share Posted July 16, 2010 LOL- if you get stuck post again, maybe with a picture of the offending item Quote Link to comment Share on other sites More sharing options...
Pete B Posted July 16, 2010 Author Share Posted July 16, 2010 Phew, I'm back in one piece - it's a tiny pressure switch to which I've applied some switch cleaner. The external trim tab is a rocker switch mechanism. It's working after a fashion but only if I nudge the tab one stop at a time. If I hold the tab over the switch continues to the travel limit (-50).I can cope with that for now - if it becomes a real problem then I'll get it off for service.

Tim Mackey Posted July 17, 2010 Share Posted July 17, 2010 Good stuff. Sounds like a replacement switch may be a good idea though - if you can get one from the distributors you could probably fit it yourself easy enough ?Try ModelHelicopters.co.uk or the distributors AMERANG http://www.amerang-group.com/index.asp Quote Link to comment Share on other sites More sharing options...
Pete B Posted July 17, 2010 Author Share Posted July 17, 2010 Having left it overnight for the switch cleaner to do its stuff, thorough checking shows it to be working perfectly now, Timbo. I'll bookmark those links for reference, ta! Pete Quote Link to comment Share on other sites More sharing options...
