Maybe 2417 for the roots with maybe 2412 at the tips with washout.
The model is big enough for flaps so use all the flap area (scale) you can get for landing. Let the flaps automaticaly add more effective washout.
I would not build any largish WW2 fighter without flaps.
Control high speed tip stall by fiddling with CG and elevator throw.
My old Royal Bearcat would snap over on its back in level flight with a sudden application of "full up"--which was about right, for me.
Just my two bits.
