another noob here to the forums, and first off i would like to say excellent info here and keep up the good work! now with the questions!(lol) on the apache has anyone had issues with sloppy u-joints causing excessive noise/vibrations?? i have had mine aprox 8 months and ran scores of cells through it and already working on trashing my second replacment u-joint (that seemed excessively sloppy right out the package) bummer! So now my thoughts are omit the darn thing altogether, which poses its own set of problems. with a 3mm drive and a 3mm propshaft i cannot seem to find anything in a flex cable that will fit into the stock stuffing tube, even checked w/horizion hobby on a flex shaft w/collet for miss llumar but the cable measures 4mm. no luck there! E-mailed steve @ ose about the .098 flex cable and he says too small in dia. for the power. does anyone know of metric size flex cables 4 sale? If not, would wire drive be for me? and what kind of power can they handle? i'm also not tooo worried about the bushing dia. in the strudder as i have reamers for .125 and could open her up a tad(thanx pa, mister tool and die man!) Also somewhere up in this post someone has been running 2200 3c lipo in their vessel as i also have tried a couple times and each time it has came back in to check temps (esc and batt normal motor hotter than usual) and smelled funny, no performance issues, smelled like hot brushes or could it be from oiling the motor bushings heating up when running higher voltage?? just curious doesn't smell on normal 7.4 voltage THANX PEEPS IN ADVANCE AND KEEP THINKIN OUTSIDE THE BOX!
