Note: This is just my Personal take on what needs to be rebuilt (especially in terms of aesthetics), it is by no means a definitive or comprehensive list.
Crafts Highlighted in RED are high priority for rebuilds, mostly due to incredibly limited functionality.
Crafts Highlighted in ORANGE need rebuilds as per the suggestion of the Original builders and/or BW.
Crafts Highlighted in GREEN has been CLAIMED and is being worked on. Please contact the original builder of a craft before claiming a spot. Suggest/comment to claim (or ping @CyrusPlayz on discord)
Unhighlighted crafts are the ones that IMO need to be rebuilt, or at least undergo major overhauls/improvements. Basically if the craft barely/doesn't work, or has a lot of potential but could be executed better, then it would likely be on the list.
Bonsai: Has Transparent clips (RULE BREAK), too much fuel storage. Generally looks a bit awkward shaping wise, especially the bridge. Fix or replace spin-clipped torps (RULE BREAK 2). Protect exposed detection (Note, Cheezebagz, the original author, has already said they are ok with all of their stuff being rebuilt, so no need to ask them again.).
Cacti: Has stone blocks (RULE BREAK). Cannot fly correctly when enemies are spawned in and flops into the water. Actually has a lot of internal space for a lazer. Give it some missile interceptors.
Mangrove: Can’t dive correctly, use lead to help it sink if necessary. Electric engines are unnecessary (The fuel engine generates more than enough power as is). Cut down on fuel storage. Looks too plain. Remove Remote Camera. Doesn’t need above water detection. Needs some torpedo defense.
Archerfish: Not enough side armour for a Broadsider. Needs to be made cheaper and more optimised(loses to the unbreakable, a ship that is 200k cheaper). Fuse the lift jets for cost-efficiency(use the exhaust corners) and split the push jets for redundancy. The Pac lenses should be sunk into the turret so that they can be better protected. Use vertical lenses if you don’t want to deal with the shot-splitting thing.
Bullfrog: Has trouble staying upright(Front heavy)in the water. In shallow water the props don’t turn on. Doesn’t have enough ammo and fuel storage.
C-Hawk: Needs better shaping. Could be faster. Maybe remove the guns because they do basically nothing. Should probably spawn in a squad.
Cetonia Aurata: Has Transparent Clips. Needs actual APS tetris(BW’s words not mine). Needs Actual armor EVERYWHERE. Jet Stabilisers should be removed. Too boxy in terms of shaping.
Eurypterid: Needs to be more Godly (Loses to the Hippopotamus, a Hard craft of equal cost). Needs more and better frontal armor (multi-backed 4m wedges and backed beamslopes are your friends). Change the Shotgun plasma for normal burst plasma (I know, its lame and meta, but this is a godly, you have to be lame and meta). Reduce the amount of EMP traps and insulate components properly. Cut down the Steam jets, change it out for CJEs or Custom props. Has more energy generation than it needs. The Lazer can be expaned. Needs more missile defense.
Toad: Doomed by the premise somewhat. Having a large deckgun like this is difficult to make hard (gets defeated by the Caiman, which is 10k less expensive and is a medium. Also gets killed by the Ibis, which is its intended target.). The gun is too unprotected. Optimise the Interceptors.
Walrus: Rebuild progress stalled as the builder (The man, the myth, the leg) has lost interest in FTD for the time being. Known issues are: lightly armored for the cost, insufficient power for the secondaries, the engine compartment, no active defenses.Rebuild according to BW’s diagram.
Flyswatter: Needs better shaping, The Heli needs to fit on the helipad. The laser is too weak. Reduce the amount of upprops.
Piorun-9 (claimed by Marcel and Whit3u): Doesn’t really look like a real aircraft/period-accurate. The missiles have a bit too much fuel. Needs to not fly into space. Has extra fuel storage that can be used for more combusters on the CJE. Maybe a rebuild can be based on the Lampyridae.
SA-2 Samson: Build using beams for the love of all that's laggy. Might need to take some inspo from the Osprey Helicopter or the XR-1A as it might not be the most period-accurate currently? IDK.
Tyranny: Subvehicle turret needs to be removed. Needs better shaping overall, it's too boxy. The Steam prop transmission can be simplified. Needs more optimised armor overall. PAC switching can be breadboarded. Butthole has to be sealed. Spread out and cut down on the Ammo storage. Remove Electric engines because it competes with the PAC cannon. Optimise internal space usage.
Gearrack: Barely able to move on land(flips over alot) and in the water. Looks too similar to the Geartooth. Vehicle type needs to be adjusted.
Hammer Squad: Flies up into space too easily and scuttle-kills itself. Too boxy and square. Not hard enough (loses to other hard crafts and even some mediums at cost equivalent). AI is vulnerable to EMP. Probably needs a hitscan weapon.
Lift: Make the shaping more sleek. Might need to rethink the APS sandblaster. Replace the transparent clips. Laser Tertis can be improved. ERA should be removed. Has way too much fuel. Try to make it lighter. Likely needs to be a broadsider. Fix the splotches of Non-fleet colours. Drop the missiles as bombs and add a thrust delay. Make the laser use normal combiners and be in fleet colours. Needs more missile defense.
Orbit: Has Steam turbines when it has no energy weapons. Has too much engine power. Likely give it a laser in place of the turbines or give it an energy weapon. Remove the flamers or change it to be a brawler. Optimise the APS tetris(maybe make it a railgun). Subvehicles should be removed. Or go with the meme option and make it a carrier because of its flat deck.
Quasar: The Side armor is too thin for the thing’s cost. The plasma should be burst single-shot plasma instead of rapid fire. The PACs are very inefficient and can be optimised a lot more. The Huge missiles should be changed out for Large missiles. It needs actual frontal armor. The Build’s current shape makes it difficult to retrofit. Likely the only thing that fits is a pierce laser.
Toothpick: Dies if someone breathes on it (I know it's easy but it should still need more than 1 hit to kill) and not evasive enough to compensate for it. The Lazer, APS and CRAMS are basically useless. Stylistically vibes more like a Heli(Nitpick). Could be put in a squad if necessary.
Wrench: Needs to be in fleet colours, needs more colour. All the weapons don’t deal enough damage for this thing's cost (Like this thing took quite a while to get the Ilex, which is a weaker Hawa Hard ship, down to like 80%). Probably should change out the Crams. Barely any frontal armour for a frontsider.
Note, Since most SP craft are VERY outdated, this list only contains the ones that especially need help (IMO). In reality most SP craft need touch-ups and upgrades.
B451L51K: Can barely turn, add Breadboard thrust vectoring OR Make the CJE an azi-jet. Use a U-turn aircraft behaviour instead of charge. Has too much battery storage for the PAC. Put the PACs on a turret so it can actually aim, as the current Field of Fire is too narrow. Needs Laser and missile defense.
C0R0NA: Too Big and Expensive for an Easy craft. Can do with less batteries. Change out the single rapid Plasma for burst Plasma (or make it more optimised for CIWS). PLEASE cut down on the Frequency doublers(not even Godlies need a 145 AP lazer). The Steam Engine can be shrunk down. Don’t use automatic propulsion. Needs more colours and Greebles and overall. Make the lasers be in Fleet colours. Up Jets can be optimised. (Its highlighted orange since although BW didn’t explicitly said it needed one, he did say “alright” to a rebuild)
CYCL0P5: Needs more frontal armor. Add ejectors to the APS or better Protect it from the rest of the craft (explodes half the internals if one gun explodes). Reduce the amount of Surge Protectors. Redo the APS with Tetris and with better shells (HEAT, Incendiary, APFrag). Make sure that the plasma cannon has a consistent Chamber to generator ratio (usually either 1m or 2m of Generator for every meter of chamber). Turn off automatic Propulsion. Better protect the engines (it's a frontsider, put them at the back). More greebles and deco (Maybe more cyclops-like?)
3RR4: Needs actual armor and not just metal plates. Could use some greebling. Probably get rid of the lazer since PAC works better for compact craft. Should spawn in squads of 2 to 3. Add some flares or Radar target simulators for missile defense. A rebuild should keep the agility of the original. Try to coordinate with the rebuild of the 5C4R4B to avoid being too similar in role to each other. (rn both are small planes armed with PAC and short-ranged lazers)
G1lg4m35H H4mm3r: Needs anti-sub buoys and missile defense. Make it more Hammer-like and alive in aesthetics. Improve PAC positioning so that it's more survivable (ANYWHERE BUT IN THE MIDDLE). Needs nuke-proofing (faster firing hitscan) and shields. Needs more side armour, redundancy and evasion. Replace small turbines with medium/large ones for efficiency. Could change out Stone for Alloy for less weight or Metal for more armour.
H3R4LDR1C E4GL3: Change out most of the HA for metal/alloy to cut down on costs. The Lazer intensity could be cut down a bit maybe? Needs updated frontal armour (either multi-backed 4m wedges or backed beamslopes, you pick), with anti-plasma spaced armour. Cut down on fuel storage and properly armour them. Look up statues of Eagles and the like for reference. Overall, just go wild:)
H0M3: Has next to no armour, add armour or add more evasion to compensate for that. Missile decoys or interceptors needed. Could use more compact weaponry (missiles, PACs, Plasma, etc.). Deco continents can be smoothed out a bit more (use deco half spheres)
KR4K3N: Add more armour or make it faster and more evasive to compensate. The PAC is very vulnerable and needs to be armored. Can cut down on the amount of batteries. Small steam turbines can be switched out for larger 3m ones(it's more efficient I believe). Don’t use automatic propulsion. Needs missile defense and EMP insulation (Surge protectors can only last so long). Needs more GPPP. Needs to be built in Fleet colours.
M4SKT3T: Probably needs to be bigger to be viable. Needs more of basically everything (armor, Active defenses, energy generation, etc.) Needs more and better detection. Turn off auto propulsion. Probably needs more colours. Has too much fuel, ammo and energy storage. Or alternatively, just change out the Stone for Alloy and the plasma for missile spam and call it a day.
M3DU54: RECOMMENDED TO DO AN UPGRADE FOR THIS ONE. The mechanics are so complex that I do not want any poor soul to have to go through the motions of figuring all of that out again. The amount of batteries can be reduced, use that space for energy generation. More frontal armor. CJES should be made more redundant and the lift jets could be moved to the centre. Just use a simple “Point at and maintain Distance” behaviour. Remove any spin-clipping.
N4G4: Too sluggish, should probably change some of that HA to Alloy, and also add thrust vectoring. The PAC is too vulnerable and can’t aim well, maybe put it on a turret? The Plasma shots should have more charges to do more damage, rapid plasma is cool but not great for DPS. Needs laser and missile defense. Keep the shaping though, It's unique. Also keep its ability to get out of the water, that's also unique.
5C4R4B: Needs to have armor protecting the engines. Don’t spam simple jets. Should also spawn in Squads (depends on the price point of the rebuild). Up to the rebuilder to decide if it is a plane or a frontsider. Try to coordinate with the rebuild of the 3RR4 to avoid being too similar in role to each other. (rn both are small planes armed with PAC)
53K1NM37: Make it more lion-like aesthetically. Remove the Steam Jets because they are too inefficient. Replace with CJEs. Plasma can be changed to a burst plasma. (multiple firing pieces, they have enough charges to spare.) Remove material gatherers, resource gathering behaviour and frontal PACs. Needs better missile defense, move the chaff emitters inside. Reduce resource storage to about 50% of craft cost. AI components need to be properly insulated, don’t spam Surge protectors. Better protect and isolate the ammo storages. Improve Evasion. Breadboard the ACBs. Optimise or remove LAMs. Remove electric engines (inefficient and uses energy that should be for the Plasma/PACs). Needs reverse for better maneuverability.
The Stonelight: Change out most of the HA for metal/alloy to cut down on costs. Needs updated frontal armour (either multi-backed 4m wedges or backed beamslopes, you pick), with anti-plasma spaced armour. The Main weapons need more oomph. Could use some missile defense (maybe change out the turret on the back to be a burst flak). Maintain the spaceship vibe but make it feel more imposing and mothership-y. Give it enough material storage to spawn a R4 (about 3 million should be good). H A V E F U N :].
