Bob,

Nothing sounds better than the sound a twin makes when they are properly synchronized. It's intoxicating (for me at least) and if they are out by more than a few hundred or not consistent through the throttle range you hear it. Will the plane fly? Yes it will. Will an engine be unreliable? Not if you didn't lean one too much. Do you need the twinsync? No you don't.

Why did I start this thread last year? Because I bought a plane with the option of using a Twinsync and wanted to know what others had experienced and get some feedback. I asked questions did some research and made an informed decision not to use it. I agree the availability of some of these gadgets are more fluff and niceties rather than a necessity. People may not have your depth of experience so they turn to trusted forums to get answers and be educated.
