Try it on a real build

The actual app, loaded with a sample RV-7A about two thirds of the way through. Nothing to download, nothing to sign up for.

What you can do in it

Read the log, open the entries, and look at the photographs
Work through the FAA fabrication and assembly checklist and watch the 51% arithmetic move
Open the equipment list, the weight and balance, the costing and the Phase I record
Look at the FAA forms and see exactly which fields are prefilled and which are left blank
Press any print button — the demo shows you the document it would have produced

Nothing you do in the demo is saved, and nothing is written to your browser. If you already own GA Build Helper, the demo cannot touch your own records.

The documents it prints

Every one of these comes out of the records above — not typed again at the end.

Builder's log

Every entry, with hours, who, where, and the photographs.

Fabrication & assembly checklist

The task list with the 51% working set out underneath it.

Equipment list

What is fitted, with part and serial numbers, weight and arm.

Weight & balance

The empty weight report from the equipment you recorded.

Costing

Purchases and budget, with what is spent and what is on order.

FAA form cover sheet

What was transcribed onto the form, and what was deliberately left blank.
