Hi, I am making a big bedroom with bathroom over my father´s house, I think that I can back to internet in 2011. I am writing on a ciber.

Any know how is the engine power of Ki-43IIB OSCAR and Ki-43III?

Is a true that Ki-43IIB have a WEP?

I am playing the B-24 Guy's overall Ki-43IIB and it has WEP!

How is the max speed of Ki43IIB with WEP?
