Bought an Avistar ARF. I also have a Superstar ARF and a Nexstar ARF. Both, the Superstar and the Nexstar, have a metal rod that you insert before joining the wing halves together. The Avistar ARF does not have the wing rod nor is it mentioned in the assembly instructions. That means that the wings are only epoxied together with a wooden wing joiner which really controls the amount of dihedral. To make things more confusing ... the Avistar RTF has a metal wing joiner rod.

I called Hobbico and they say this is correct. The ARF doesn't have a wing rod, but the RTF does. The Service Rep couldn't tell me why, but did say that they haven't been having any problems reported about the ARF wing not having a rod. It just seems to me if a trainer (Superstar and Nexstar) required a rod and the RTF version required a rod then the ARF would require a rod.

Can anybody shed some light on this? At this point I am pretty confused and a little paranoid about just gluing the wing together.

Thanks
