Been flying an Alpha since Dec. Check the fuel tank often, because the screws on the firewall rub against the bottom front of the tank. Over time, they created enough of a hole that fuel was leaking everywhere in the plane.
After crashing the first Alpha, we got another one. I put a strip of foam tape on the front edge of the tank. Decided to take a look at it, and there were already little indentations in the tape after only 3 flights!
