O.4 flight time to check temps and the oil hose leak. Temps appear to be well in control with the various baffle adjustments. Got about 325 left and a little lower right at 2600 rpm, 110 mph. The gps showed the airspeed is pretty close. Didn't do any 3-leg checks, but just in general. Winds were pretty light. Did one 360 outside the pattern to check that temps were staying in line. Post-flight checkout - the new, pro-made oil hose leaks at BOTH ends. Before, it had just been at the oil filter spacer fitting, but now it's at the oil cooler too. Will add voishan seals and try again.
