Default Diamond Dust-Weight ,Speed & Momentum

*I am going to build one of these this fall. I am getting the feeling off a hot Shrike at the moment along with large warbirds etc. Weight of a plane is a really big deal acording to most of us. What if it would actually help.
* You coast down a steady hill in an empty pickup truck and you will gain speed but only to a certain amount and level off. You coast down the same hill in the same truck with an extra 1000lbs on and you will start off a bit slower but will go alot fast further down the road.
* You take this Diamond Dust which is suppose to be around 2.5 lbs. If you keep the plane as light as possible the engine mayl always be pulling the plane even in a dive.
* What if you increased the weight a bit to 3, maybe 3.5 lbs. You will still be traveling around at an impressive clip but you come down on a high speed dive, You should be going like, well i cant say it here but that momentum should help increase your speed at the bottom of the curve by quite a bit. Any thoughts?

Mass cancels out in equations on projectile motion.

1/2 * mass * velosity squared = mass*gravity* height

i think you said it your self, coast down hill. that Dust isnt coasting.
i've seen my own dust with a previous owner go as fast as the engine it had then would allow. the plane wasnt holding it back, it just wouldnt go faster.
the only thing with weight, we have the Weston Magnums, when they first came out they where kits. the heavier ones where more stable. but lost it big time in climbs
