Hey guys, I've gotten far enough along in the planning process of my UAV to start asking power questions. I'll be using a NexSTAR EP (http://www.towerhobbies.com/products/hobbico/hcaa09.html ) for the airframe, a DragonOSD ( http://www.intelligentflight.com/webstore/DragonOSD-Starter-Kit-P34C1.asp ) for the OSD, and ArduPilot for the autopilot. This leads me to several questions:1) The NexSTAR comes with 2x 8-Cell 9.6V 3600 mAh NiMH (GPMP0362) batteries. Would it even be advisable to use them to power the OSD and the autopilot?2) The DragonOSD "was designed to run off a 2S or 3S Lithium-Polymer battery" and recommends a 2S LiPO as opposed to a 3S. As such, am I OK in powering it with the NexSTAR's included NiMH batteries?3) Would there be any issues powering the ArduPilot through the NexSTAR’s ESC?4) If the above questions are non-issues, about how much flight time to you approximate I'd be able to get off of a single charge with the included batteries?Thanks,Adam

You're fine with the the NexSTAR's default batteries. But eventually, if you have the money and stick with this project, you'll probably want to upgrade to LiPos for the better power/weight/size performance. But it's not essential.
