how insane would adding 2 hobby rockets to a trainer be?
In response to flapbreaker's comment about the Wright Brothers...
The Wright Brothers had already done enough research before they flew that they knew exactly what they were getting into.
In response to the notion that this person is wanting to shoot the rockets...
This is a whole new can of worms. Look at the design of an estes rocket. It is designed to do one thing well, fire vertically. It is not balanced to do anything else. It is very bottom heavy, which means that the rocket would most likely fire in an upward direction regardless of initial orientation. Of course this puts the wing in a direct path with the burning exhaust of the rocket engine.
In other words...
if you do this, do it in the middle of nowhere and for god's sake, get a video of it to show us.
