Nev Haycox Posted November 29, 2012 Share Posted November 29, 2012 Can someone tell me if its ok to use Hitec two piece adjustable servo arms on aileron servo or are they too weak? Nev. Quote Link to comment Share on other sites More sharing options...
GrahamC Posted November 29, 2012 Share Posted November 29, 2012 I think the answer would be.... It depends! 40 size sport plane, probably OK, 50cc petrol Extra.... Er no! What do you have in mind? Quote Link to comment Share on other sites More sharing options...
Nev Haycox Posted November 29, 2012 Author Share Posted November 29, 2012 I know it was a bit of a beginners question but I don't really know what the arms are designed for, I guess to control throws in light applications. I wish to use them on a Seagull Harmon Rocket, I’m sure they’ll be fine. Nev. Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted November 29, 2012 Share Posted November 29, 2012 I wouldn't use them for anything other than throttles where they used to be useful to match the servo throw to the carb. These days, with computer radios and adjustable travel volume they are redundant. Quote Link to comment Share on other sites More sharing options...
Mark Kettle 1 Posted January 31, 2016 Share Posted January 31, 2016 Most times if you use a servo arm disc you have to cut off the others arms so the cable or rod as clearance from the other arms when it rotates, using a hot-wire you can cut the other arms off easier.

gangster Posted February 1, 2016 Share Posted February 1, 2016 It would be a very last resort to induce me to use one. I cannot think why one would be needed on aelerons particularly with computer radio. A hitec servo arm would stay on without the screw with luck ( no don't try it) but if the screw even got loose with one of those contraptions the whole linkage would fall apart Quote Link to comment Share on other sites More sharing options...

Denis Watkins Posted February 1, 2016 Share Posted February 1, 2016 The boys are quite clear Nev, these Hi Ted arms were designed for low load application to the throttle barrel. They are excellent to getting that difficult to make, final adjustment from tick over to full throttle. As Bob says, the computer radio has surpassed this need now. Fit your servos with a fixed arm, fixed linkage, that cannot come adrift, and use your TX to make final adjustments. We all know the law, if it can work loose, it will work loose. Ailerons are far too important for any risk, as is any control link. Best regards Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted February 1, 2016 Share Posted February 1, 2016 it's also a 3 year old thread! I'm guessing the OP has got over the idea by now Quote Link to comment Share on other sites More sharing options...
