| Tracking issuesFor what it's worth, even though I currently fly a T-Rex and not an MX400, I had tracking problems at any RPM over 2400 using the plastic head on 325 Pro Woods. Upgrading to the aluminum head, even with plastic blade grips, allowed me to solve my tracking problem. Now my rotors track perfectly. It's actually sort of eerie, I'm not used to rotors which aren't off-track in the slightest, normally they're at least half a blade width off or something.
My suspicion, however, is that this kind of thing holds true across different helis. The plastic head, if I understand correctly, distorts slightly under heavy G's. In my case, reducing the RPMs of the head below 2400 also resolved the tracking problem across multiple sets of blades.
And BTW, I *LOVE* the flight log. It's really nice to see someone collect lifetime data on a heli to show some real-world reliability figures. My local hobby shop says they no longer carry Shoguns and MX400s because they, to quote the store clerk, "suck", but clearly your maintenance record on your 400 isn't very different from that of many T-Rex owners. |
