How thick is the wing? Would servos like the HS45 (or similar size) fit?
If it's anything like the original B900 (and I suspect it's pretty much identical), the wings are quite thin. You'd probably do best with D47's all around - they are small and fit upright in the fuse. HS45's are way too big - too heavy, too. The key to get thermaling ability out of this glider is to build it as light as you possibly can.
