Twin nitro engine syncronizing gizmo?
I am wondering if anyone is familiar with an item that plugs into your #3 throttle channel and syncronizes/matches the RPM's on a twin engine nitro plane. I am wanting to syncronize 2 Magnum XL70 four stroke engines on a Dual Ace. If you know the name of it and have used it, please share your thoughts and experience with it. Thanks
Best regards
