You would have to work up some sort of bracket or mount as the trays on the 914 are bolted to a bracket that is attached to the intake plenum. But they would overcome the issue with the original trays. You can see pics of the 914 trays on my build web-site http://www.europaowners.org/N914XL I believe there's a decent pic at the bottom of the first image page of the last album. There are probably better pics in the engine installation section if you want to rummage around a bit. Hope this helps. Good building and great flying, Bob Borger Europa XS, Rotax 914, Airmaster C/S prop.

I'm glad to hear that your system worked through the calibration process OK. As you say, I suspect mine will do the same.
