Carefully adjusted evenly, assisted with verniers & again as accurately as possible aligned the ailerons with the centre of the wings. Took it up myself this morning (reducing aileron throws by transmitter but not enough) and within seconds after take-off shattered my nerves when it rolled quite violently to the right. Steadied it by stick & completed a left turn to allow max time for straight line trimming. First time I have had to make such major trimming. Trimming madly to the left, it continued its right roll. Overtrimmed it & when I left sticked, produced a rapid left roll & ended up inverted. After many mosquito-like moves, 3 heart attacks & stained undies, I had it high enough again to trim it again to level flight. Cant figure out why ailerons needed to be trimmed 3/4 left to produce level flight. Any ideas? First was Moneyshot - money shot & now Eratix. Are plane's names influencing behaviours or just me
PS. Underside is clear film so orientation colourscheme quite adequate.
Oh bugger don't ya hate it when that happins ?? !! You got it back OK tho'
I'm not sure why it would be so far out of trim unless you changed something when you shifted the linkages out on the servo arms, perhaps the servo arms weren't perpendicular and shifting the linkages changed the center position of the ailerons. Just a guess ??
