Hi John.. Been following this for some time....have you considered that the motors are not going into reverse ! ..but that the prop. wash is pushing against the underside of the hull ....thus giving a reverse thrust similar to that used on a jet engine ....this would only show at increased revs A rx going into fail safe would not cause this problem neither would not removing a red lead on an esc....I have flown planes with 2....4....and 6 esc,s and never cut a red wire off the esc. Can't wait to learn the reason in due course Berty
Hi John I think its time for the bath test......half fill bath......run motors with model held up in air to make sure motors are running correctly.....lower model half way into bath props half in half out of water.... check motors still running correctly...then fully into water....motors must still run correctly.....they can't reverse when they smell water !.....can they? Can we see photo of props and rudders....the solution may lie elsewhere I love this problem it's a good un !l Berty
