Hi,
Some of my players were interested in getting grav bikes, and (as they were at Bulhai Freeport, Blue system, described in the Pirates of Drinax set) I decided there were some "surplus" IISS Grav Bikes for sale (for a slightly outrageous price, certainly as they were "used", i.e. 20+ years old). Good negotiation skills brought the price down. But I digress...
I was using the IISS Grav Bike from JTAS 6 (as it has MgT2e stats, unlike the one in my Grand Census DGP book from... way back).
However, looking over the stats, they are chunky and expensive.
So I decided to see if I could figure out how the IISS Grav Bike was built, reverse engineering them from the description to the Vehicle Handbook.
Basic = TL 15
12 hull = 6 spaces = Light Grav Vehicle chassis
Traits = Open Vehicle = Open Frame. Discrepancy: Open Frame has 1-3 spaces, and this is 6 spaces. Hm.
1 Crew + 1 Passenger = 2 spaces
250 kg cargo = 1 space
Cost per space = Cr 30.000 + Cr 10.000 for an Open Vehicle
Range = 7.500 km, which is +50%, so probably Fuel Efficiency, so cost per space = +25%, makes it Cr (30.000 + 10.000) x 1.25 = Cr 50.000 per space.
6 spaces = Cr 300.000 for the chassis.
Now the equipment:
Autopilot (sdvanced) Cr 15.000
Communication System (advanced) Cr 250 x 2 for increased range = Cr 500, range = 10.000 km
- Encrypted Cr 4.000
- Satellite uplink Cr 1.000 (uses 1 space)
Computer/4 Cr 3.000
Control Systems (advanced) Cr25.000
Life support (short term) Cr 10.000 (uses 1 space, I guess? It's 'one space per 20 people or part of')
Navigation System (advanced) Cr 50.000
Sub total = Cr 108.500 for equipment
Sensors (advanced) Cr 25.000 (for range = 25 km, Elec DM +2)
- hardened: doubles initial cost
- increased fidelity: doubles initial cost, gives Elec DM +3 (uses 1 space)
- increased range: doubles initial cost, range increased to 250km
So total cost for sensors is either Cr 25.000 x (1 + 1 + 1 + 1) so Cr 100.000 or Cr 25.000 x 2 x 2 x 2 = Cr 200.000
So, adding up everything, I'm at either Cr 508.500 or Cr 608.500 (depending on how you handle the sensor components doubling the initial cost).
The JTAS 6 article claims a cost of Cr 843.500, so either I made a mistake, or the author miscalculated, or my Vehicle Handbook is missing some errata.
And on top of that, it's 6 spaces, where the Vehicle Handbook indicates an upper size of 3 spaces for an Open Frame (making all the additions that use 1 space unable to be fit, and also making it a bit less chunky by going back to 3 spaces, which would also reduce the Shipping to needing 1.5 tons instead of 3, which is almost as much as a regular air/raft).
Thoughts? What am I missing?
