On the other hand the aluminium chassis is so soft on its own that it'll probably get straightened out when attached to the plastic chassis.

My alu chassis was slightly bent right out of the box... Didn't lay flat on a perfectly flat surface. I contacted Xray support and they never heard of any other with the same "problem". Anyway, when attached to the composite chassis part it straighten itself out and seemed flat so I didn't bother.
But... Now after 4-5 race days I can see the rear being slightly bent upwards. I absolutely love this car and I haven't broke a part on it. I have used it solely on carpet and can't see any sign of wear except for the slight bend. I have seen the same tendency on other XB4s as well. Use a caliper or a metal ruler on its side and hold it against the rear of the alu chassis and you will probably see a gap at the very rear end.
