Default RE: Engines for Hangar 9 Twin Otter

Just installed 2 OS Max .46 AX's in mine.... have not flown it yet. Balance came out great (no weights needed). It's a tight fit.... but came out great. I kept the regular mufflers on it. Just tweaking out the controls right now. Used the mix function in my Futaba 8FG for the elevators (you will need to reverse one side & mix gear with elevator or buy a servo reversor). This will be my test bed for the Twin sync since the cowls are easy to get to. The reason I selected the OS 46's..... is I have had a history of solid performance with them.... a very stable and dependable engine.... with great power for this size bird. For a twin..... stable is good. The OS Max 55AX.... not so much. (great power for size.... but finicky).
