Ehh
Drone is aerial so if that aligator cannot jump to 3 meters I dont think so ;)

Shouldn`t that aligator showed up on the radar? Radar in drone or Sams UWB are capable to pass liquids, arent they? Or does surface reflects radar waves? In fact, I recall hearing that water can fool microvawe detectors, so Im not sure?
(BTW: Sam...Idea of UWB radar confusing Usltrasound :D UWB is milimeter lenght electromagnetic wawes, Ultrasound is ...well.. sound. Movement of molecules etc. Completely different stuff)

it's not jumping at dalmatian.

As far as the sensors. I must admit I am no expert. but I assumed (in other words ruled), that water surface reflect radar and ultrasound waves. being covered he hidden from the plain camera and he was plainly visible to astral view.
Sorry for a small delay ;)

That drone part was on Sam.
As for that radar under water, Also lack knowledge about it
For that vector thrust: It about dog sized drone. Do you think it would really make such noise? IDN its signature right now, that should help us to determine such thing, well its not breaking through sound barrier or something. really need to read if there is something on this at Arsenal or some rules:(

How about strenght? Do you negate the recoil in the amout of strenght or what did you mean by uncompensated?
Take aim was simple action, right?

Strenght adds 1 RC at STR 4 (maybe more, really IDN), White Knight has 6 points of recoil compensation, So if you fire 10 bullets you will get -3 for uncompensated recoil

in SR4A, pg. 152  there is
Characters can only counter a recoil modifier with recoil compensation or gyro stabilization.

but that might have been changed elsewhere. point me to that paragraph if so.

and I must admin I am a little lost with the description of the white knight - it says you have 5 points of gasvent, but the notation is 5(6) - anyone can provide explanation?
also, Sichr, how much ammo is in the belt?

Sorry for a small delay ;)

I found nothing in core and Arsenal, dig a little on the web. it got me wonder more. The classic vector thrusted examples are figher jets, missiles and similar. There is a fancy drone the has vtol capabilities, by shooting the gases through four movable thrusters (looking like wings).

Regardless when Doberman is medium sized drone of a size of a dog. The Dalmatian is LARGE. so at least twice as that. Even if it has lighter frame (it has less armor on the greater body) then most of it weight would be fuel. There is no data in the rules for that, but I'll guess it's weighting 250 kg. do you imagine how large must be jet engine to thrust 250 kg into the sky? an 'jesus-how-loud' it must be?

The secondary problem is the operating time. jet engines burn the fuel like hell.

so it's actually the size of a beaver drone, and you actually need to drop down as it flies over you.

The radar is basicly ultrsound vision, just stro-get, so it penetratrs walls bodies and almost anything else that does no absorb the waves.
When home will post full description, but as far as i know - water is not one of the materials that do this.
Prepare for the worst, hope for the best and expect nothing!

and enjoy the crispy tan it givrs you with its engines.

AFAIK, it's not only the question of material, but also the surface. the wave reflect from the surface at the angle it had approached. You get surface when environment change (eg. from air to water). only waves that fall directly at the surface (angle 90) pass through (depending on their energy). That's why on the naval ships you got both radar (for surface monitoring) and sonar (for underwater monitoring). Note that the sonar sensor is actually installed under the level of water.

I see, it has +1 body then Doberman
Im sorry for that . This drone will have to stay outtside the tunels.
250 KG is too much on the other side...we can talk about it as it wont matter with the drone out, but IMO materials and compounds used for built (even in 2070) are something far from what`s used today. Well, im not an aerospace engineer. Will do some research eevening on this topic, it quite new for me.

Belt: 100 x Stick`n`Shock, reserve 100xRegular is loaded on the Beaver, 90 more left in the ammo bin in Rover

There is VERY VERY VERY big difference between sound wawes, taht are unable to pentrate any material, and Milimeter Radio wawes that are capable of passing thwought xx cms of steel or plastoconcrete. Saying that there is no difference is saying that your subwoofer works on the same basis as X-ray generator :)

Possitive. Well, and that is why i hessitate, there are submarine hunting aircraft bombers.  :-\

I think you're right on the weight - maybe it's time to start a discussion on rules forum. until we solve this, we can assume 100 kg for the the doberman and 250 (including fuel) for the dalmatian.
I'm ready to change that as soon as we have some other opinion on that.

same about radar, once we get more info we'll change the rules, until then, I assume that radar waves reflect from the surface of water

Sichr, you're the only one that can have init greater then Sam, could you make the rolls? Maybe that other roller will work for you. unless you declare you delay anyway to see Sam's action I believe he will shred the poor beast to pieces, so he could make the rolls already.

look for Leigh Light

consider ww 2 technology 130 years old... :)

that could work. The problem with that is the wave are emitted almost directly down and thus passing the surface border. Also it says that the radar was able to catch them during the final phase of the attack run - that is close to the surface from high altitude. I still believe that from almost horizontal position the wave would be reflected.

reading more on the subject, there is a lot of technical details in articles to follow, but they still keep to the one point, L/L had ASV (Air-To-Surface radar) Mk II. at MK XI (the last one in the article, possible, end of ww2 but maybe a current model, there is no info on that) could detect surfaced submarine at 20 km range from 600 meters altitude. That's very good result, but still it's catching the top of the ship onthe surface not the submarine below the sea level.

Hm, possible. thats why I love Shadowrun, man always learn somthing more about  the world around him :)
On thing about this UWB radar. When I first read it, I thought that it gave character 360 view, well, it seems that it is concentrated radio beam that follows LOS. So its as easy to miss something as it is when you are looking around you in daylight with your own eyes..

and still there is nothing there on detection of things underwater.
