Questions, Do you check CG with an empty tank ?.
To balance as per instructions I will need to load 5<6oz of lead into the front of the plane , IS THIS NORMAL?
How accurate does the CG need to be?
1. Yes check with empty fual tank
2. Yes unfortunately many AFf's tend to come out tail heavy. Minimise the lead and move stuff forward, get the battery up front under or over the fual tank and move everything forward if possible. By the way the quality of the airplane makes no differance at all, a tail heavy airplane is a killer.
3. Needs to be accurate. Poorly balanced models (particularly when tailheavy) along with excessive control throws are simply the number one killers of new airplanes. additionally when you balence an airplane and cheat a little nose down for 'mother and courtry' you have now balanced the airplane at an unknown position. The airplane is only balanced at the desired position when it is level!
