Any word on develeping a 4 engine sync? I have a twinsync on a twinstar and love it! now I have a 123" wing span b-17 with 4 saito .65's almost ready to fly. was going to put in 2 sync's one for out board engines and one for inboard engines, but would rather have one sync do all 4 engines. The twinsync is a great product and have bought 6 sets of twinsync's for different projects. great insurance for those expensive airplanes.. Keep up the great work!!
