RCU Forums - ARC Jupiter

Hi all, just transferring a message I wrote for the Irvine 72 in this section too, since it concerns the Jupiter.

Just writing back to say that the very thorough carb cleaning did have a huge effect on the way this great engine works, re-installed it on my ARC / Modelfly Jupiter, it transitions absolutely perfectly now, the thing has become ballistic, even 80% power is too much, just keeps on climbing vertically & nearly lost sight of it once. Full power on take off sees the aircraft off the ground in 2 seconds flat and she slows down nicely to land, but I do have to use the least possible reliable revs on the ground (~ 1,300 rpm idle on 10% nitro content & 18% oil fuel).
I wish I could post a link to a new onboard video I've made, if anyone's interested visit my YT profile "Irvine7214x6apc", first video by date is that last 6-flight session one. A bucketload of fun, I'd say the 72 and the Jupiter are "a marriage made in heaven". Only difference is, on that video I used an MA 14x6 prop (10k revs on the ground easy), now I've installed an APC 14x6 prop on her - should perform even better, RPM are pretty much identical.
