4.11 F4U Performance

Try this and see if it works.

warm it up to at least 40C and full rich 120%, prop pitch 100% (max rpm), rad closed because it's cold engine.

After you release the chocks and just before you hit the end of the deck,crank the prop pitch down to 0% and pop full flaps. if that doesn't get you airborne, then something is wrong.
