when fighting any allie plane with the 109 and they start a scissor i cut the throttle and flap it out.... i can usually stay behind them and as they try and turn inside me run outa E and they are done....
I've been trying a flat scissors in a P47 followed by a rolling scissors when they are out of phase (not sure I can really tell yet) with the hope that they are expecting the flat scissors to continue and get surprised by the slow flaps out roll and overshoot. It's worked a couple of times but I'm not the best of shots and often miss my one snap shot. Been taking quite a few hits doing this also while doing the flat scissors.
In a 109 I do what you do or go vertical if I get surprised and stay above them. The rolling scissors really only works when someone is expecting an easy kill and tries to stick with it too long and overshoots.
I've always meant to pay more attention the engine torque thing. I'll have to experiment with that. I also need to work more on working flaps in and out to help keep E better than the opponent.
The 109s seem to be overall better planes 1 vs 1 but the higher numbers we have had help balanace it out. There is always the stay alive as long as possible and hope a friendly will shoot him off your tail defense in a multi-con fight.
