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.
