Default Jab 3300 with fuel in wings

Oren's RV 12 now has about 10 hours of flight time with the Jab 3300 and fuel tanks in the wings, all weight and balance problems worked out fine.
A few adjustments to the cooling ducts are in progress and we will report the performance when the numbers are all confirmed.
First Flight July 11

Test Pilot Andy Hostetler Reporting a rate of clime of about 1000' fpm Engine running very smooth and aircraft handling great.

With the 12 being okay for E-AB, this could be a real winner.

Default Jab 3300 update

We now have approx 18 hrs on the jab 3300 rv12 . We are working on fine tuning the carb and cooling ducts. As of now we are seeing very good cooling with cht's of approx 300 (very good ) We are experimenting with the bing jetting for max performance and economy. Will update with speeds and climb rate when we get it fine tuned.

Joe and Oren,
Who did you use for your cowling build? That engine obviously requires special attention to the cooling needs.

Default Beautiful

Cowling is beautiful - really nice job. Certainly improves the looks of the RV-12.

I applaud the efforts to power the 12 by 'other' engines. Will be following this thread closely. Well done!

I noted the distance from the nose wheel to the prop. On the Viking, even with a 4 inch extension, we are still close to clipping the nose wheel with the prop.

Default cooling

Pete in regards to the cooling.
I put the oil cooler on the oil pan and added the chin scoop.Oil cooling is perfect.
Head cooling is not a problem at all. All you do is follow Jabiru cooling duct instructions per Jabiru USA.
