I just finished putting one of these together (the ARF), but haven't flown it yet. I have an OS52FS in mine - boy, what a job to get that in!

Question I have is about the wing bolts. The nylon bolts supplied seem pretty flimsy to me (smaller than the 1/4" nylon bolts I've used on my other planes). I've thought of replacing them with steel, but am having trouble finding these with the correct threads. Have others flown the plane with the stock bolts or replaced them?

Thanks
Dave
