In the past two weeks I installed the H3-2D gimbal and bound a Graupner MX-16 transmitter to the phantom. The gimbal and transmitter work great even though it was my first time soldering and there were a few hiccups. Yesterday I went out for the first test flight after installing everything. The Phantom flies, the gimbal is steady, and the graupner allows me to control the gimbal tilt, but I did notice a few issues. 1) After powering on the phantom the gimbal does not position itself completely level with the ground. To be more specific: when looking at the front of the camera, the left side droops slightly. Is there a way to calibrate the default position of the gimbal? 2) Should I adjust the motor speeds after installing the gimbal? It seemed like the Phantom had a harder time getting off the ground than before. When taking off on my 3rd battery it slumped forward causing 2 of the props to hit the ground (though this might be my fault for not giving it more power during lift off). If I should adjust the motor power/gains/idle are there recommended settings? Finally some things I noticed and learned after yesterdays test flights. Stock batteries (the only ones I have) last a maximum of 8:30 minutes. As soon as the LED on the phantom starts flashing red I have a lot less time to land than before installing the gimbal. The phantom seems to become very sluggish when the leds flash red. Before installing the gimbal I still had plenty of time to land after seeing the leds. Everything looks a million times better with the gimbal. I realize this isn't news to anyone, but I am still blown away by just how much better everything looks when properly stabilized. The Graupner MX-16 is wonderful. Works just as well (if not better) as the stock TX and it has a proper gimbal tilt dial. I still have a lot to learn with the MX-16 considering for now it's calibrated according to a YT video I found (i haven't mapped IOC controls yet).
