I'm checking back with Vans to make sure I understand the color options and delivery assembly vs ordering with McFarland. Thanks Walt for the suggestion!
Donít forget the PMAG limitation with the -12, and the extra weight of the -9 would help with CG.

Default Composite 3 blade

Iím not sure who started the ďif you go composite blade route you will be aft heavy on the 14Ē but seems a myth. Vans designed the 14 with a 360 and that weighs 18 lbs less than the original IO390. I donít know what the EXP 390 weighs but as one builder points out adding an accessory case increases the weight. Not to mention adding a stand-by alternator. My best landings are made when I have my bicycles in the baggage area and tools. Check your W@B calculations assuming different prop combinations.
