I just started on my Mirage 2000 from aviation design so I will like to give everyone some pointers of how to go about building one of this.If you like you can use my techniques or we can share yours thank you, Nick. Here are some pictures.
First you need to cut all the openings for the doors and also I opened up an extra access panel right behind the main blockhead, close by the CG point these will help with the smoke system and also to incorporate and extra fuel tank under the main one to get a couple more minutes of flight.
I am running a P300 Jetcat and that tends to suck a lot of fuel
