Normally I do not post same thread on two forums or so, but this one is really ticking me off......
Well overall the Protos flies ok, if I could get the darn tracking to stay.....
Pop her up and tracking is dead on, fly for abit on some aggressive 3D and hear a bad vibration, bring her to eye level and the tracking is out a quarter to half inch. Pitch pump the heck out of it and I can get the tracking back in.
Originally thought the dampers, changed em all out same issue. Changed (2) different "pre rolled on glass" spindles, issue still exists. Getting frustrated I order all new main blade grips, new bearings for grips as well as new thrusts. Guess what issue still exists... well then I am scratching head and think about blades. So I throw on a new set of RT 430mm I have here, issue "STILL" exists.
In inspecting the main blade grips I have I can see the thrust bearings have "TONS" of room to move, maybe I have some bad molded grips? Thing is the ones in stock box as well as replacement ones are all the same and have this room to move, I am talking about .5 to 1.0mm cleareance in whole around the outer race of the thrust bearings/washers. Stock grips and replacement grips () of them all have this room to move washer/bearings, the back radials however all are very snug tight fit....
I have also looked at the top mixers no apparent slop, all linkages do not show any play either. Really furstrating,,,Tried all different headpeeds as well, it will constantly go in and out of track 3-6 times in a 4 minute flight and when the vibration sets in and the tracking goes out you feel it is going to self detonate, lol.
Anyone else experiencing tracking issues like this on Protos? I have a ton of building experience and what not and this is more than abit boggling at the moment so I thought what the heck post it, see if anyone else is in this boat to....
