Hi,

I too have an Avistar equiped with an OS .46FX.

This is my first plane, bought new, as an ARF. It came with a 3-piece wooden wing joiner and has a wooden main spar (no metal seen while building).

The instructions clearly say:
Note: when performing the following steps, be sure to use a sufficient amount of epoxy to form a complete and solid bond between the plywood wing joiner and the two wing halves. This is the most important glue joint on the entire airplane.

Ross stated that it wasn't the wing joiner, but the main spar.

Not good! (in my opinion)

After reading all of these posts on this web site, I may never get this thing off the ground... now I'm wondering if I should use nylon wing screws like I've seen on other airplanes.

I'm ready to break-in the new .46 and get it started for the first time, but now I'm also wondering about the "thrust factor".

Maybe I'll just take it up - see what happens - and make modifications to it later.

I suppose in the (almost) worst case sceniario, I could buy a replacement wing set and reinforce it with metal rods... but I just wanna' fly and have fun with my new found pals!
