Classic "What were we thinkin" moment. Friend gives you a SIG Fazer. You put radio/engine/servos on(profile) it. You take it out to local fly field. See the original owner of the plane. You ask him to maiden it since he would know how it handles. He agrees and as he does a takeoff roll, he lifts and does a right roll then a left snap roll into the end of the runway,,,Dead silence is broken by the whisper from his lips," Dude, your ailerons were reversed".

An extra check of controls, oh say 30 seconds, woulda saved me 5 hours of repair.'

Moral of the story: just cuz ya think ya/they should know, dont necessarily mean you/they know...
