Hello. Fairly new to the ALTA6 and having some issues on a shoot. Had a very minor "tip over" after landing on rough ground yesterday. Damaged one set of props and replaced. Now when it flies I have to hold right stick way back from centre, especially in POS hold. The issue seems to magnify during the flight until it is hard to control at all and requires almost full pull back on right to remain horizontally centred. Any help would be greatly appreciated. Thanks!
