AscTec Hummingbird with AutoPilot User’s Manual
mAh. With a state-of-the-art 2100 mAh battery the
vehicle is able to hover up to 20 minutes without any
payload, and up to 12 minutes with 200 g of payload.
Make sure you prepare your battery such that it can
definitely not get damaged by hitting the frame, even
in a crash. Otherwise the battery could explode! Here
is an example of how to mount a battery correctly:
The black foam on both sides prevents it from being
hurt by the magnesium parts of the frame. Configured
like this the battery slides into the battery slot of the
vehicle and holds inside by friction. Of course, there
are also other ways to prepare your battery for a safe
operation. This is only an example.
Lithium Polymer Batteries (LiPo) can be very
dangerous if not handled correctly. Please read and
follow the instructions of the battery and charger
manufacturers! Do never short circuit a LiPo battery
and use safe connectors!
2.3 Teach-in of your

Connect the USB module of your wireless da-
ta link (XBee 2.4GHz or Radiotronix 868/900
MHz) or the AscTec USB-to-cable adapter to
your Windows PC. If your system requires a dri-
ver for the USB chip, please download it here:
http://www.ftdichip.com/Drivers/VCP.htm. The USB
module will then be recognized as a COMport and
appear in the Windows device manager.
Turn on the vehicle and start the

be sticks on the R/C), one channel to enable and di-
sable the serial data interface (two or three position
switch) and one channel to switch between manual
mode, height controlled mode and GPS + height con-
trolled mode (three position switch). If you have ne-

mend the following setup for the first four channels:
