The Rimfires are from Horizon, the 2410-9y's are from here, www.aarchobby.com

I use the 9's in my Hobby Lobby B25, and used them in my one other P38, both spinning 3 blades and they worked out fine. If memory serves me, in the B25 they pull 16.8 amps combined, and I run them off a single 3S2100 lipo. For props I think I'm going with the 3 blade units from Hobby Lobby, instead of the ones I ordered. Comes as a hub and 3 seperate blades. Blades are a lot less prone to breaking vs ones like the MAS or APC versions, though no counter rotating versions.
Part # on them is FS300.
I'm planning on doing mine as a belly lander, so will need some blades that will take some abuse.
