Twister Hawk
USB PC FLIGHT SIMULATOR CABLE
Your Twister Hawk is supplied with a USB cable that connects via the socket on the rear of your transmitter
to a Windows PC or notebook PC.
Using free R/C ight simulator software, downloadable from the Internet, you can run a realistic R/C
helicopter simulation that will allow you to practice until you feel comfortable enough with the simulator to
have a go with the real model.
The transmitter can be used with a Windows PC to run a number of R/C model ight simulators. The
advantage to the pilot is twofold: by practising using your own transmitter on a simulator you will get
familiar with your very own set of controls when you y your Twister Hawk for real.
Secondly, a simulator is particularly good at introducing the basics of R/C ight for those unfamiliar with the
four ying controls, the trims and their effects on a helicopter.
For advanced pilots wishing to practice 'nose-in' hovering where the controls are effectively reversed; a
simulator is a great tool
We recommend the FMS free ight simulator available as a free download from:

There are hundreds of different models available for use with the FMS simulator. For example, you can
download a Blackhawk helicopter for use with the FMS Simulator from this URL:
