Second the motion for a WM T-34.. With a OS.46 they are hitting a little over 90 mph (radar) in the pylon races around here.... They are also great pattern planes and land like a trainer... Great flying plane... The WM 40 size P51's with a 60 in them have been clocked at over 100 mph (radar again) as pylon racers.... I have never seen the Dago Red race and am not sure of the speed on that one... I have one and it weighs a pound more then the regular P51's ... The fiberglass fusalage is a little bit heavier I guess... I have a Saito .72 in mine and it is fast but not as fast as the 60 2cyles in the regular Mustangs...
