Now buy taking off the fake air intakes how much of a significant change will there be at full speeds. I thought that it wouldn't make that much of a difference when the model is at full speed.
Given two patriots with the exact same setup except that one has the intakes and one does not, the one without them will be faster. It is difficult to know exactly how much difference it makes unless you radar the same plane with them on and with them off. Not really a practical way but the only one to measure the difference accurately. Suffice it to say that it would probably make several MPH difference. But then, if maximum speed isn't your thing, go ahead and put the useless, draggy, simulated intakes on the plane.
