First, Boomerang RC, great to deal with. Quality products and quick shipping. My purchase went into a Boomerang RC Atom, this engine is perfect for the Atom and other models of similar size. Easy to install, set up and get ready to fly.
The first runs in my Atom were at 25 degrees F above standard day conditions. Once fuel system was bled using the pump test, the engine was easy to start and ran right at published specs. The telemetry is nice, although I am still learning for my Spektrum radio system.
What makes this an ideal engine is the size, weight and fuel burn. I have a 94 oz Jet Tech fuel tank and easily get more than 10 minutes as long as not running 100% throttle the entire flight.
