I didn't get a manual with mine, but got the CG off a message board (maybe RCU??). 93-103 would make a lot more sense. The LE to front of the wing tube is 88mm. LE to the center is 98mm, right in the middle of the 93-103 range. I'm at the aft end of that now, so with a little lightening in the tail, I should be able to hit low to mid 90's. My last flight was getting closer to the kind of performance I'm looking for. I'll have the new motor in this weekend, so we'll see how that goes. If the CG is right, then my last goal will be to bring down the overall weight as much as possible to get the wing loading down without busting the aft CG limit.
Thanks for the info!
