Part 2:

Recap

In Part 1 we developed the concept and bought the frame and weapons of a new mecha, the YF-38A Fox, which is intended eventually to be a transformable fighter/humanoid.

For the recap, cost and space are not included in servo or weapon write-ups

Shields:
No shield.

Pilot:
1 pilot in a canopy-type cockpit in the torso.

Sensors:
Superheavy sensors in the head.

Step 6: Buy Additive Systems

Recon Systems: A jet fighter doesn't really need very much in the way of advanced sensors.
Electronic Warfare: Likewise, jet fighters don't get much in the way of EW.
Remote Control: Modern technology doesn't allow for "bit" units, so remotes and their control are irrelevant.
Options: An ejection seat is it.  1 CP, no spaces.

1 CP, no spaces for additive systems.

Step 7: Figure Base Weight:

Weight from Part 1 is 26.5 tons.  This is about what we expect for a fighter jet.

Step 8: Weight Efficiency:

Weight efficiency on this design is unnecessary.

Step 9: Flight Systems:
Fuel Weight: 1,000 km worth of fuel (about 600 miles) weighs 2.65 tons and takes no spaces.  This range, however, is far too short to be useful for a fighter jet, so we will buy an additional 2,000 km worth of fuel and put it in the wings for another 5.3 tons.

Current weight: 34.25 tons

Propulsion, obviously, will be Thrusters.  We have to use heavy Space Efficiency on thrusters to make them fit; this is acceptable for this design.

The design speed for the YF-38 is 24 MA in fighter configuration (1641.6 km/h or Mach 1.38; this is supercruising MA, by the way); this translates to an MA of 12 in humanoid configuration.  Wings add +2 MA so we have to buy thrusters for MA 10.  Since the legs only have 2 spaces left, and the proper thrusters cost 6.5 spaces each, we'll have to efficiently take care of 4.5 spaces.  This means that each thruster costs 8.75 CP and takes up 2 spaces in each leg.

Afterburners aren't dealt with by Mekton Z rules; in my own house rules, Afterburners add +4 MA (in humanoid mode) but also use up two hexes (0.1 km) worth of fuel for every hex (0.05 km) traveled.  The YF-38 in afterburner has 32 MA (3110.4 km/h or Mach 2.62).

Step 10: Figure base cost:

Cost from part 1 = 90.4 cp
Additive Systems = 1 cp
Weight Efficiency = 0 cp
Propulsion = 17.5 cp
Total base cost = 108.4 cp

Total Weight: 34.35 tons

At this point, we have the following spaces left:

Head: 1
Torso: 3
Right Arm: 1
Left Arm: 1
Right Leg: 0
Left Leg: 0
Right Wing: 0
Left Wing: 0
Tail: 2
