I am a bit confused on how stats on vehicles cross over. In a battle where an AT-ST and speeder bikes are fighting and according to the rulebooks the weapons entire profile is in planetary scale.

Here’s my confusing. 1 point of armor is equal to 10 points of soak. Now this makes sense so a blaster pistol can’t take out a walker. But I would think that a speeder bike would be able to do damage. If a speeder bikes light repeating blaster does 11 damage, plus auto-fire, on a good roll if you have a fabulous gunnery skill, you can get a lot of damage on the walker but probably not 30 to equal the walkers armor of 3.

I guess what I am wondering is does the mean when it says the entire weapons profile uses planetary scale or just the weapons? Would 3 armor then be basically 3 soak? If so, wouldn’t take make a blaster pistol able to take them out? How does this balance out between a vehicle weapons attack on a vehicle versus a PC's attack on a vehicle?

3 Armour is actually 30 soak, since it's an x10 multiplier. Another thing to keep in mind is that soak/armour is applied per hit, so an auto fire weapon that does 13 (character-scale) damage per hit—or 1 vehicular damage—won't be doing anything to any vehicle with armour. Even if you managed to activate auto fire 5 times, that's 5 hits of 1 damage, not 1 hit of 5 damage.

Speeder bikes are not anti-vehicle vehicles, they're anti-infantry. Hence the light repeating blaster. If you want to take out a walker, you better have some heavy weapons, preferably those that operate on vehicle scale. If you're stuck with personal-scale weapons, I'd suggest picking up an anti-vehicle mine, that breach 4 will eliminate almost any ground vehicle's armour, and it'll do 2 damage to your walker. Not enough to take it out, but it'll still hurt.

Just think back to the battle of Hoth, how much damage did the air speeders blaster cannons do to the walkers. The answer is none, that is why they had to use to tow cables to trip them.

But a speeder bike is not designed to take out a walker, or even an armoured vehicle. The weapon on a speeder bike is designed to mow down infantry. The air speeder, on the other had, has a vehicle-scale weapon, and is designed to hurt armoured vehicles.

Maybe you're confused as to what we're talking about. The speeder bikes are what we see in RotJ on Endor. Air speeders, from ESB, are completely different.

After rereading your post, I realized I didn't actually answer your question. For the speeder bike, the weapon is personal scale. Armour 3 is always armour 3, or 30 soak. When a weapon is noted as being personal scale only the weapon is personal scale. The vehicle is still planetary scale.

Of course, there's really nothing to stop anybody with an armed speeder bike from popping off the LRB and replacing it with the much more effective Auto-Blaster which is only slightly more expensive and has a much lower Rarity (3 rather than 7).

EDIT: Oh yeah, and the Auto-Blaster (unlike the LRB) isn't Restricted either!

Nothing at all! Still retain the auto fire quality, and it does 3 planetary scale damage!

and scares the HELL out of the other swoop gangs in the depths of Nar Shadar!

could drop the idea on a party with them being highway robed by a gang using them... im putting that in the Encounter list

In that instance a GM may rule that the power output of the bike struggles to power the Auto-Blaster, giving it the Slow Firing 1 quality as the capacitors charge up. Just a suggestion if suddenly there is a group of 5 getting around with them terrorising the locals...

If the designers thought it was going to be a problem, then they should have made Silhouette 2 vehicles unable to mount planetary scale weapons. But since they didn't do that, go big (guns) or don't plan on going home.
