| when i was using a 5s lipo pack ... i too used to have issues trying to get the CG right.
i had moved all my electronics to the front, including the gyro (which didn't work for me, i was getting interference from the ESC/motor). i then moved the gyro back, but moved the lipo pack even further infront - it over hung a bit (from the battery tray).
this worked out fine for me ... had to cut the canopy a bit though.
now, i am using 10s a123 ... mounted similar to trex 600. no problem with CG at all ... 
cheers, khan |
