Hi.This is a Stockalike B-52 Stratofortress that comes with an X-15 and a D-21 drone, that get mounted under the wings.
There is a pre set up one inside the craft folder that is within the main folder.
It's desciption lists the custom key set up.
2 and 3 toggle the flaps and fins and allow it to take off with a light pitch up at 140 m/s
1 toggles the spoilers for easier landing.
With the experimental craft hanging under the wings you have to allow for their aerodynamic surfaces adding to the control. It can get twitchy under load above 10,000 metres.
The spoilers use BREAKING GROUND to work and that is a REQUIREMENT for them.
The internals are stock but if you have Raster Prop Monitor installed then the blank monitors will be replaced with multifunction ones.
The engines have a thrust reverser.
I have tried to put enough instructions in each parts description to help if you are building it yourself.

The License is within the Craft folder.

Hope you like it.
