Funny, I had that same problem. In fact, I almost started to sand the wing down to fit, until I realized you cannot "slide" the wing onto the fuse - you need to drop it onto the fuse from the top. It is a very tight fit. I went with the Saito 1.80 over the OS 1.6 b/ I like the torque of the 4 stroke. I also think I'm going to get a fuel regulator - NOT a pump (www.ironbaymodelcompany.com). I'm getting mixed reviews over the Perry Pump (VP-20). I want the regulator b/ I'm going to bring the tank back over the CG.

I'm also going to scrap the Carbon Fiber push rods - I'm going w/ Hanger 9 titanium rods. They are easier to deal with.
