    looking at the old thread on the other site I said a couple years ago 150mm but I may have changed from then.
    Hi,

    What would it take to persuade you to measure it for me? ;)

      Hi, the CG for my red raptor is 150mm. A correction for inverted level flight is not necessary with my plane.

          Hmph.

          I guess I'm very nose-heavy, then. :(

          Thanks!

            from the book is in the limit H=70.

              So two would be 70mm wide, 47 tall and 160 long, no problem. The F-22 has a very large battery area.

                Yes, but 70 is on the limit, if some reason have 36 dont fit.

                  But 70mm is the width not the height. Mine are 75x 45x145 and there is a ton of extra room every dimension.

                    Hello all, I finally found time to unbox and assemble my 90mm F22 and I have some questions. first off, with a admiral 5000 bat. I have to push the bat. back half way off the battery tray to even get close to neutral CG. with the gear up and the canopy cover installed it is still slightly nose heavy??...I see videos of guys pushing the bat. closer to the blue box and flying that way. I have checked my measurement (150mm from wing/fuse crotch) and accurately marked it. Do you all just fly nose heavy?Or is the plane not that sensitive? What am I missing.
                    Also, how much if any expo you guys using with this aircraft. I'm new to EDF, any advise would be appreciated. won't be flying till spring anyway. Thanks
                    Hi, I have the same issue or not, I have the battery back to get 150mm.
                    do you fly like this?

                      Question does everyone check cg with gear down and plane in flying position not inverted ??

                        Is there other possibility that that?

                                Anyone change the esc to have reverse thrust? If so what esc do you have?

                                  I believe that either the Spectrum Avian or Castle Escs support reversing

                                      Very nice flying! Love the flat spins and those flip-floppy maneuvers near zero airspeed.
