The probe already has avionics built in, and removing it is going to mess up all the delta-V calculations. Ditto for the launcher, a Atlas-Centaur replica. I could remove and redesign if you want me to. On that note, another quick question: When those avionics rings say "6 minutes of control" does that mean 6 minutes on the ring's internal battery, which can then be recharged, or does it mean that regardless of EC availability after 6 minutes it goes "NOPE"?
Bit of info about failures:
As a rocket travels through space on free-fall, the only force acting on it is gravity. As it climbs out of the massive potential well of our home planet, it loses momentum to gravity. But that momentum doesn't just disappear (like it does in KSP.) The equal and opposite force on the rocket is on the Earth itself. The Earth takes on the momentum that the rocket loses. The momentum is returned when the rocket crashes, so the final momentum cannot change, but during the free-fall the Earth will have a changed velocity, and move slightly. So through your (inevitable) future failures, remember:
Whenever a rocket falls from the sky, that means someone is moving the Earth.
Yes, I know the rocket's exhaust also transfers momentum to the Earth. But that happens much faster, so the velocity created by the launch lasts longer than that created by the freefall, so... the Earth still moves, just in the opposite direction.
