A and C
In late August I am hoping to fly down from Biggin Hill to S.France at 4,000ft or more depending on clouds as I will be VRF, but would certainly like to get up into the cooler air, where it is less bumpy ( one of the problems with the RV6 is that although it has high wing loading, it is very rigid airframe and in turbulence it does not ride it well, unlike the Robin DR400/180 I used to take to France and Italy ). I have found that if the OAT is below 16c or there abouts then the temp of the CHT and OIL are fine. So yes, I will be doing the step climbs if needed. Thanks John
