My splitter has about an 18" cord that runs from the socket to the splitter . The splitter sits under the passenger seat and the cords to various devi ces are taped to the side of the console so that passengers don't get tangl ed up in them. None of the cords go with me when I leave the plane. Dan Schmitz Tiger 4518B KASH I have an Aera 550, an Ipad and a portable Intercom which all need power fr om the cigarette lighter.

What a draggy piece of engineering. Was there some design reason for that or was it just an oops? Also why 3-lbs on a 6" tube instead of 1.5-lbs on a 12" tube? Looks like either of those lengths would fit inside the wingtip if the holes had been drilled in the "right" place.....

If yours is not flush to ~3/8" inside the tip when the aileron is centered in the trail position, then Tiger LLC screwed up (again) and mis-drilled your aileron counterweight holes in the torque tube. This is actually a fairly common rigging failure, that is seen across American, Grumman, Gulfstream, AGAC AND Tiger LLC. Kinda like how they didn't get the elevator halves aligned when they were drilled into the control horn... another common factory screw up that seriously messes up the rigging. I've fixed dozens of them. It messes up the stop geometry because one of the bolts that holds the aileron counterweight on is also the moving part of the aileron stop assembly. If it is clocked wrong, then it hits the stop too soon one way and too late the other. Back to the story... When the aileron goes UP the opposite one is going down. Remember your PPL training? This causes ADVERSE YAW that you must counter with the rudder. By having the weight come out of the wing tip and into the slip stream, it creates some drag on the down going wing, helping to decrease the adverse yaw from the opposite aileron. Its not a bug, its a feature. ;-) As for the length of the arm and the amount of the weight, a longer arm would have required a larger, stiffer tube to support it. I wasn't there for the planning meeting, but a lot of little compromises were made, and perhaps this was one of them, where they gave up the weight increase to have a drag DECREASE due to the smaller hole in the bottom of the wing tip??? --Bob Steward Birmingham, AL ________________________________ Message 5 _____________________________________ Time: 08:22:54 PM PST US From: 923te <923te@att.net> Subject: Re: TeamGrumman-List: Aileron Counter Balance Weight So if my counterweight didn't go out the bottom of the wingtip then I might have to pick my feet up off the floor once in a while???
