== YASim Nasal & Thruster based parachute ==
[[File:V-1 Parachute.png|350px|thumb|V-1falling slowly with a parachute]]
Tomaskom developed a realistically behaving parachute for YASim aircraft. It is capable of a slow and stable fall and can recover the aircraft even from very severe rotations. <br/>
It all began as a question about a parachute which ended by brainstorming of the best approach, you can read the related thread here: <br/>
http://fguk.eu/index.php/forum/development-hangar/4546-external-reactions-forces-in-yasim <br/>
<br/>
Re-implementing the code elsewhere is very easy, most of it can be blindly copied with just some adjustments (trigger binding, chute area, ...). There is a thread on the main forum with HOWTO for implementation, see [http://forum.flightgear.org/viewtopic.php?f=49&p=215650&sid=97b2010406d31b6fc2fabc7cf8b1c8f8 Parachute for YASim (Thrusters & Nasal)]. <br/>
Currently there is a reference implementation in a special version of the V-1 flying bomb: <br/>

The drone (Firebee) for which the parachute was requested is not yet publicly available. <br/>
You can also get an idea of it's stabilization properties from this video: <br/>
