    Hi, everyone. I just bought the latest 550E DFC Pro kit with the 730MX and all electronics, except the 3GX. I've had a great run out of my 550E V1 (first FBL heli) and was looking to upgrade it some more, when I was offered the latest 550E, with the new green canopy (450L style), for what I thought was a really good price. This will bring my FBL heli collection total to 15 (it's an addiction, I know :D).

    Upgrades I'll be using are a metal battery mount (that will allow an extra retained battery strap and more cooling for the ESC under it), Helioption metal canopy release, Tarot metal canopy nuts, a metal tail boom brace clamp, and a metal vertical tail fin spacer.

    I'll be using a yellow K Bar FBL unit in this one, like my current 550E. The yellow has a really good 3 axis MEMS sensor, and is very smooth.

    I'll update more as the build progresses.

      Thanks. The motor feels strong. It's also quiet and seems very efficient. Mine at 100% throttle doesn't have the whine I've heard in some videos. But I would like a bit more head speed. No sign of a 17T yet and I'm concerned Align hasn't left enough slot length in the motor mount to fit it.

      Just wondering with the new lower kv motor what's your final ratio @beenflying and @feral?

      Dunno @5Fidy I think its 850kv with a big pinion giving you a similar final ratio

      With the 850kv motor the final drive is 1:7:3.85, so kv * voltage divided by 7, for head speed. Sounds reasonable on paper, 22.2 x 850 = 18870. 18870 / 7 = 2695RPM, but 90 percent efficiency would be 2426RPM (9340RPM tail).

      I should add that my combo kit came with 520mm blades. The super combo (with the 3GX) comes with 550mm blades.
