Testing out the tail holding in the dinning room after a few adjustments thanks to Slobberdog and Lee ( yes that was fine, works really well now) I almost flew the heli was at that moment of takeoff where cyclic controls are working and it is just beginning to drift left with the thrust from the tail rota when.........................nothing. I think they are called brown outs. Sudden loss of power when the receiver lost signal. On the Spectrum receivers a red light flashes the number of time signal is lost. I almost lost control when the motor suddenly cut in again when signal was regained. Brown trousers moment I can tell you. So back to square one but with a lesson learned, do not test in the dinning room. Cheers. Oh by the way does this count for my first flight. LOL
