• The Biplane Forum is a large global active community of biplane builders, owners and pilots. From Pitts to Skybolts, to older barnstormers, all types are welcome. In addition to our active community, our content boasts exhaustive technical information which is often sought after for projects and maintenance. This information has accumulated over the 12+ years the forum has been in existence.

    The Biplane Forum is a private community. Subscriptions are only $49.99/year or $6.99/month to gain access to this great community and unmatched source of information not found anywhere else on the web. We are also a great resource for non biplane users, since many GA aircraft are built the same way (fabric and tube construction). Annual membership also comes with two BiplaneForum.com decals.

Hi,

How long does it take for your 360's to get to 180f at oats near or less than 40f? Also, are you able to see oil temp withing 5 min of start at oats of 40ish?

I have a "standard" Skybolt cowl with a blocked off oil cooler. At cool temps as described above, I have to wait in excess of 10 min to see 100F on the ground. This after starting with an oil sump temp of 90F. In flight, it takes 10+ min of trying to get the oil temp to 180F. Is this normal? I would have though that by starting with a sump of 90, temps would have come up sooner than that. The gauge is accurate, and the probe is mounted per normal location top left. I have a 150w pad heater that is left on all night. The top cylinders were at 70ish before start.

All this normal or coolish?
