I thought I would render up another little video of one of the newer 50mm airframes being offered up by Sky Angel, the A4 Skyhawk. I am flying it on a Thunder Power Pro Power 45C 3S 850mAh lipo. Flight times are around 4 minutes, with varied throttle settings. I put 617mAh back into the lipo after this flight. This one is easy to launch and land and weighs in at around 11 ounces and some change, AUW.
