Used Moguls are reasonable? I wanna know where you shop, I havent seen one sell for less that $400 on Evilbay.
Go for The Annie, they are easy to seperate from the Big Haulers by the added details and metal siderods. The pilot issue is easiely solved by adding a small amount of weight like a 1/2oz fishing weight or like me, adding a 1/2 oz self adhesive automotive tire weight on top of the pilot wheels frame. The Annie has a proven track record of reliability. Like others here, the C16 is very much a wait and see model, they are not kidding about “troubles” with 1st production runs from this company. This engine has been a very very long time promised, many of us think its been so long because hopefully, they learned their lessons from past releases that might have been a little “rushed” and this time they are hopefully taking their time to assure a reliable product, time will tell.
