It's interesting that they'd move the radiators. The North American inlet setup made use of the "Merideth effect" whereby (I'm not an engineer...so have mercy if I'm not spot on with this), but the air rammed into the inlet and heated by the radiators passes out the back just under the te of the wing through an adjustable orifice. Using water spray bars in front of the radiators (as most unlimited racers do) helps not only with cooling but allows even greater expansion. The P-51 inlet drag is better than negated at the proper (speed dependent) setting of the outlet door. There's actually miniscule thrust generated! There's a plane in the works, can't recall the name, that actually routes hot exhaust into the expansion area behind the radiators to superheat and steam the water to further this Merideth effect. I believe this particular plane also uses an area ruled fuselage...the coke bottle shape above the wing...to increase the Mmo...to keep the the cross sectional area constant and help with the huge drag increase as boundary airflow approaches transonic speeds (even though the plane is subsonic). Hattend...I wish Rare Bear would hae raced this year. Huge dissapointment for everyone out there. Does the Bear use a P-3 Orion prop? Hope to see you out there next year!...Dennis
