FLATPLANE CROSSPLANE BIGBANG

[Allred]

A little long-winded initially but worth the nearly 30 minutes of watch-time. A very good explanation of the differences between Flatplane, Crossplane, and later even the Bigbang firing systems.

Good info.  Ive always wondered why they don't fire right down the line.
I mean, the 2 on the ends and in the middle set in the same position, like my 750,
I always thought, why the heck don't the rise, fall and fire in order.
Like the old airplane radial motors.

Now, I know🙂
