I just looked at RCU.  Terrible news.  Do you run one servo on elevator?  Just wondering if losing one would be catastrophic?  If the problem was in the transmitter two servos wouldn't help.  Don't give up!

>>It's Chris Johnson from So Cal's plane. He's going with 5 cell packs. The wattage you said is about right. I think 900 would be really well actually but was asking here for backup, as it's only going to be 4.25 lbs give or take. Do you think he would need more than 200 watts per pound for Intermediate and Advanced? Heck, my 14XL's (Well, 14XL now, RIP) barely give me that.

>>Probably needs 900-1100 watt range.  As far as Dualsky is concerned, the XM4250CA or XM4260CA size motors would probably work.  These motors will handle 11x6 to 15x8 props depending on battery cell count.  How much prop clearance will he have?  What pack config, 4S, 5S, 6S?

>>I am not familiar with Hacker or Scorpion in this size motor tho I hear Scorpion motors have a great reputation.  There is a guy on RC Groups flying the Helios 63e plane with a Scorpion 4020-12  on the equivalent of a 5S Lipo and says it has way more power than he needs.  So, a 4S might be about right.
