Case/fan blade impingement
When first operating new unit, top fan blades were bound by the tight fitting case. Had to loosen case screws to free it up and and progressively tighten them until the fan blades were impinged, then backed off again. Excellent service when purchasing product, got it faster than expected. Price was right.
NO MORE OVER HEAT IPAD
This X Naut product stop the over heat temperature of iPad during flight. It happen to me in few flights until I purchased X Naut. It’s a bit bulky and was attached to MGF suction cup articulating arm. So there was wide area of adjustment on eye level. In my experience, I would attach an external battery to x naut through micro usb for extended flight. Highly recommend it to all pilots.
