RE: walkera vs. align
Hey Norrmannen,
True, if the problem is known, they should try to fix it in the future similar sets they sell. They do seem to try as best as possible to get my 2 problems I still have (motor-temperature and the ESC that doesn't have governor-mode as advertized) resolved and will probably send replacements for those to test with as well. I'm trying to get an Align BL-420LF motor and the Align BL-25G ESC. If that combo turns out to work well, I'll certainly suggest they use that in the future, as the difference in price is minimal. The Align-motor also seems specifically designed for the Rex and comes with full specs.
Grtz,
Traveller
