Hello everyone,So, my brother happened upon an SF Airways-45 in a dumpster at the storage unit place he works at. It needed some minor repairs and, most of it (save but the repair needed part) was still in the bubble wrap. I finally got it all together and I'm having some engine issues. I bought 2 2250Mah batteries, one for each ESC, 2 EFlite 40 ESCs and, EFlite Delta V 480 engines to go in it. In the booklet, it shows to Y the ESCs to 1 receiver connection. I did this, after pairing the ESCs to the remote (a Futaba 6J.) My problem is, in Y connected setup, the last engine to be have it's ESC switched on will only start to turn when throttle input reaches 30-35% (I'm not sure the exact number but, it's in that range.) Both setups work perfectly on their own. When the lagging one is switched on first, the opposite happens. The lagging engine now runs when it is supposed to and, the properly functioning one lags. I was hoping they would even out at a certain point but, when practicing taxi yesterday, it kicks the aircraft to one side.I just tried to get them to work in mix mode on the controller but, had no luck. I tried plugging the lagging engine into slot 5 on the receiver, then getting it to activate with 3 (throttle) as master and 5 as slave. The only way it would come on is when I was trying to adjust it in the negative. It would come on, but as soon as the throttle was pushed up it would shut off immediately. I tried adjusting the sub trim, hoping that was the issue, but that would not fix it. I tried switching to reverse direction on that channel as well. It would only kick the engine up to high throttle. Input on the stick had no effect on it. It would only stop when the channel was put back to normal direction.Does anyone have any clues on how to get this to work? I tried calling Horizon and they told me to try the mix mode, which I just tried.
