Looks like the Danny Boy team is going that route too, so we shall see.
The Danny Boy liner has a whole lot more car behind the front axle & a lot less mass in front of it. I would expect the weight bias will be pretty good when it's done plus they have room behind the axle for the "other"
engine too. They also have a history of running huge tail fins since their big crash.
Rationalising the dart theory, as the speed increases the length needs to increase with it. A dart is a short range low speed projectile & an arrow is a long range high speed one. This isn't an opinion, physics denotes why they work best where they do. Reverse the role of these two & see what you get.
The higher the speed is the smaller the correcting input needs to be.
This is also relevant to steering. I've seen many LSR vehicles with handling problems attributed to the steering being too fast & resulting in the driver unknowingly overcompensating. I helped some guys with a door car a few years ago with this issue. They weren't convinced I knew what the hell I was talking about but were so frustrated they were willing to try anything. Redrilling the Pitman arm reduced the ratio & solved the problem.
