Omar, I can't get the photos to enlarge but that looks like an ARF?? Is it??
Dobra, I have tested several different APC props with the two different engines I have had in this plane, the 1.20 OS FS and the YS 1.20NC and it fell into a pilots choice thing. Both engines seemed to like the 15X8 for the way I like to fly but the 16X6 gave the plane better verticle. The 16X4 wasn't a bad choice either. The only wood prop either of these engines worked well with were the Xoar wood props in the same size and pitch range. I can walk into any hobby shop here and buy the APC props so most of my testing was with them.
I like a slow plane with a lot of torque so I tend to go longer with less pitch on my planes. I know that looking for that super prop costs a bunch of money but it's just something you have to do.
Brian and Big, I wish I was closer to you guys so I could teach you how to glue something. You are missing all the big glue stains!! If you don't use up an 8oz bottle of CA how do you expect anything to stick??? Big, get back out to your shop and at least squirt some thin on the sheeted surfaces!!!

Brian, I don't know how they went about going from crush cutting to the laser but I figured they just went from the original die cutting plans and plotted them?? Scratch building from magazine plans there are always several mistakes like off sizes. Wish I could build one of the laser cut kits to see what the differences are. I do remember having to do a bit of sanding to make things fit, was it a lot??
