Fast and tough - verify correct cg during build

The first thing that impressed me about this wing is all the sparring. Even the vertical stabilizers have pre-installed spars on both sides. Overall it's a very stiff and strong wing. The biggest issue with this wing was the incorrect CG stated in the manual. It's been a while since I purchased and built it so I don't know what the current manual states. The original manual specified 195mm to 205mm from the nose. This puts the balance point too far aft and the wing will be uncontrollable. For my build the CG was located at 180mm which required modifying the battery tray to use a 3S 2200mAh mounted sideways at the very front of the tray. I prefer more battery rather than dead weight if possible. My setup for power is a 2208 1800KV with 7x6 prop. With this combination the wing is pretty fast and still surprisingly stable. However, with large elevator travel it will still snap-spin as I found out when throttling up and applying full elevator to abort a landing. It spun over and nosed into the ground before I could blink. Most wings can't tolerate overly-aggressive elevator travel without snapping over so this isn't anything unique to the Sport Wing. Although it does seem to be a little more pronounced on this wing because of it's compact size and higher wing loading. Just keep the speed up and limit the elevator travel. The snap-spin into the ground revealed that the weakest part of the air-frame is probably the wooden bulkheads of the battery/electronics tray that hold the cover with wood slots. Some modding with a flat carbon fiber spar and some CA to repair a crack in the nose and around the tray was all that was required to make it airworthy again. Otherwise the tray and cover work fine for normal flying. The motor leads did need to be extended to reach the tray from the motor with the ESC located in the tray. With the mentioned electronics, this wing will go ballistic with ease and stay airborne for 20 minutes moderating the throttle. Even with more than a dozen wings, I still like to take this one out when I need a small-ish, simple, fast flying fix.
