We've always discouraged direct sales in favor of supporting your favorite eflight dealers. However, there are a few support areas that we've decided to take on. The first is free upgrades. These are available for download, but for those who prefer a CD, we offer this for $5 ($8 outside of US). Also, since V2 has been out for 5 years, dealers don't normally carry V1 upgrades. We now offer the V2 upgrade on CD for $10 including S&H ($13 outside of US). Since we lost our European dealer, we now offer the latest ecalc for non-US customers for $42 including S&H. Again, please support the dealers above whenever you can.
