As a 40 year veteran of RC Flying I was really surprised with the performance of this glider. Fast climb rate long flight times on the battery are good, and in the right conditions, even thermal soaring can be accomplished. I like to pad my batteries with foam wrap in addition to velcroing them to platforms and apparently, during some acrobatics, I had jarred a piece of foam battery wrapping loose. Shouldn't have been much of an issue, but due to the design of the nose of the aircraft, the air ducts didn't provide enough ventilation and I found my engine smoked out during flight. Looked like one of those old WWII fighter plane videos with a slight trail of smoke behind the plane as I brought it down for a landing. Ordered a new motor and it flew great again. I actually own 2 of these planes, my first one only had foam hinges so I reinforced the control surfaces on that one with hinge tape. The lane flies rather fast for a glider and is a tad bit "squirrely" to handle sometimes so I wouldn't recommend this for a first time flyer without assistance. Overall, a nice plane for the price!
