EasyCo,
I have two of the Revell Bf 110 G-2 kits and both were fine with no warped parts.
My last airplane I built was the ProModeler Ta 154 which had major warpage of the right wing, I ran hot water over the wing parts and bent the wing in the opposite direction of the warp and then held the plastic under cold water to ''freeze'' the part in the desired shape. It took four tries before my wing was straight.
Hope this works for your kit.
