42% extra 260 help
Hi. I am building a 42% sd extra 260. Could someone tell me their CG. Also am planning a ZDZ 160 super. Is this enough for a wannabe 3d pilot? thanks.

Re: 42% extra 260 help
Standard CG should be right at the wingtube. That should put it dead on or slightly nose heavy for maiden. From there you can move it aft to your liking.

Re: 42% extra 260 help
Thanks. U guys are awesome. Planning on just mufflers. also I am a little confused on servos, some say 2/aileron, 1/stab is ok. Using hitec 7955's. I think I will 3/wing, 2/stab so I wont have to worry about flying the hell out of it.

Re: 42% extra 260 help
Elevators can typically get away with 1 servo per half with today's torque ratings.
Ailerons as well can get away with 2 servos for torque ratings but some planes need 3 due to flexing more than torque. Not sure on SD extra if it needs 3 in the wing but it def won't hurt to do it other than the wallet and piece of mind.
