I have no glitching with the long servo leads.. The 2 tail servos and out-board wing servos work flawlessly... I am using Hi-Tec 425 servos but that shouldn't make a difference.. I know of a good way to make your servo ext lead tubes..You need about a 1/2" I.D. tube, so get a 1/2" dowel about 4' long and wrap wax paper around it on an angle. Then cut newspaper in 2" strips(any paper will work) and dip it in a 50/50 water and wood glue( I use Tite-bond II)mixture.. Then wrap the paper on an angle around the tube. Use about 3-4 wraps, each wrap should be the opposite angle of the last one... Let dry over night, then pull tube off dowel. If any wax paper is still in tube, just force the dowel back in and it will force it out... Any ? just reply to me or e-mail me and I can phone you...
