Jedra's Mini Time-Trial Pack.
The missions load as a mod and in the downloaded rar, once unpacked, you will find a folder called @JedraMissions. Copy this to you Take On Helicopters root folder. Launch the mod with the "-mod=@JedraMissions" switch.
Once loaded you will find them with the rest of your Time Trials in Single Player/Time Trials
If you like them, I might make some more - so please give some feedback if you can spare the time.
Please note - I am not the best pilot in the world, so the bronze silver and gold times may either be too easy or too hard. I basically made the gold time a few seconds quicker than I could do it, just to give those with more skills than me a better challenge. If you think I should change the times then please let me know!
I hope you enjoy this little addon!
