REFLECTOR: Aileron control stick pound pull

[Jeff Howell]

I just installed my cables and I have alot of friction as well. probably more than 2 pounds... My cables are also 90" long wich is considerably longer than the 54" useing currently. thanx Jeff > From: sbakr at comcast.net> To: reflector at tvbf.org> Date: Sat, 3 Jan 2009 08:05:11 -0500> Subject: Re: REFLECTOR: Aileron control stick pound pull> > Hello Andy,> Confirm the ailerons have freedom of movement with the cables disconnected. > Make sure the foam core does not interefer with the 6' long aileron torque > tube inside the wing.> The aileron push-pull cables will have more internal friction when they are > new.
