Unfortunately, there's no way to get into twins slowly. You gotta run with the big dogs or stay on the porch.

There is really no difference at all flying a twin... Until one engine quits [X(]

IF that should happen, you'll want to drop the throttle, add rudder to the side with the good engine and start planning your landing ASAP

You'll need to hold a lot of rudder and avoid turning toward the dead engine. If you're the praying type, go for it. If you're not, this is a good time to start

I perfer to keep the throttle simple and get the engines in sync manually. Here's how I do it:

Put a pin inside each carb barrel and close the carb on the pin - now you know that both carbs are in the exact same spot. Make sure that both servo arms are exactly the same. Note: If you're using Futaba Servos, the 6-point star shaped servo arms can be rotated from one arm to the next with slightly different positions to make it easy to match them.

Now with the throttle at idle, adjust both throttle linkages so they align with the throttle arm on the engine (While they are still closed on the pins).

Now they should be mechanically in sync.

Start both engines, go to full throttle and adjust the high ends until you can hear that they are in sync (Or use a tach if you can't hear it)

Go to idle and if they are not in sync, see which engine transitions better, then adjust the low end on the OTHER engine.

Mike great input, exactly what I was hoping for. Thanks a bunch. I know I'm not ready for this bird, but at my age, ability and experience are on conflicting curves. So I might as well make the jump now. It anin't going to get better. By the way, I'll use a tach with the hearing being on the curve with ability [&o]
