I checked your record and it looks like you ARE set to cars. Next time you see any airplane ad in the car forums if you can please right click it and copy the url and/or image path. Email it to me at support at rcuniverse dot com and I'll check to see if it was not tagged correctly. the 3D plane ads should NOT show ever in car forums or throughout site if you are set to Car Universe. IF you do that indicates a mis-tagged ad.
