Whiplash Power launcher
Make sure your Whiplash will leave the launcher fast in any
situation, prop size, or engine size, with a small modification.
Install a cross brace between the rail stand uprights. Make sure
it is installed low enough to clear the prop safely.
You can use a wood dowel or a fiberglass rod. It is required
to keep the rail spacing correct correct for the shuttle during
a power launch.
