No I don't plan to change the props skr8pn. Partly because these props screw on one right handed the other left handed so I would have to change the prop shafts also. Might have to if the props won't stand the brushless motors.
Have been working on mounting a rudder which went better than expected. I waterproofed a servo but haven't got it mounted yet. The motors and esc's showed up from Hobbyking this week so have been busy soldering on them. Found out that the Birdie 50a esc's only work with stick radios, so I will either have to buy another pistix from Ose or switch to my 4 ch Tactic which I just got another rx for. I think I'll do the latter.
After gutting the electronics and motors I tried fitting the new motors into the mounts. Discovered that I had to turn the mount themselves 180 around and also cut the farthest back support that was there for the other motors. The motors I'm using are 2632 3400kv outrunners. They have 2.3mm shafts so I can use the drive system that they came with. Here are some pics of my progress.
