How do I plan my build sessions?

Break the build into sub-assemblies that can be painted separately. Plan sessions around drying times — paint one sub-assembly, let it dry, work on the next. This maximises productive time.

How long should each session be?

Most modellers find 1.5–2.5 hour sessions optimal. Shorter sessions lose too much time to setup. Longer sessions lead to fatigue and mistakes. Take breaks when doing detail work.

What order should I build in?

The general order is: clean parts, assemble sub-assemblies, fill and sand, prime, paint, gloss coat, decals with setting solution, optional gloss seal, weathering, final assembly, then a final matte or satin coat. Apply a gloss coat BEFORE decals — a smooth glossy surface prevents silvering (trapped air under the decal film); the matte or satin coat goes on last to restore the scale finish. Paint interiors and hidden areas before closing assemblies.

Build Sequence Scheduler — Plan Your Build

Plan model building sessions with estimated hours, session count and recommended sequence.

Model ComplexitySets hours per sub-assembly: simple 1.5 h, moderate 3 h, complex 5 h, masterclass 8 h

Number of Sub-assemblies

Major sections to build separately

Paint Scheme ComplexityPaint workload multiplier on build hours: basic ×0.5, moderate ×1.0, advanced ×1.8

Working Session Length

How long each build session runs (1.5–2.5 h is typical)

How We Calculate This

Session Planning

Build hours = Sub-assemblies × Hours per sub-assembly (set by complexity tier)
Paint hours = Build hours × Paint scheme multiplier
Total hours = (Build hours + Paint hours) × Experience × Perfectionism
Work sessions = ⌈Total hours ÷ Session length⌉
Drying days = ⌈Estimated coat count × Dry time per coat ÷ 24h⌉

Total calendar time includes both working sessions and drying wait time. Use drying days to work on other sub-assemblies or prepare next steps.
