This is the shopping list. Every electronic part a TerraHawk FPV needs, in the order the manual fits them. No shop links, because those change and the parts do not. Search your usual shop for the exact name. The Shopping Summary gives rough price estimates.

The manual tells you where each part goes. This page tells you which part to buy. For component choices this page wins. For everything else, the manual wins. Carbon spars are in the manual, step 1, and are not repeated here.

Four decisions, then it is just shopping. Your route (basic or advanced), your battery voltage (4S or 6S), your lift prop (8-inch or 7-inch), and your FPV system. Everything below follows from those four.
</aside>
Both routes share the airframe, motors, ESCs, battery, servos and radio. The difference is the avionics.
| Area | Basic FPV build | Advanced autonomy build |
|---|---|---|
| Flight controller | H7 wing controller | H7 wing controller |
| GPS | One M8-class GPS | One or two M10-class GPS |
| Airspeed | Highly Recommended | Required, DLVR sensor |
| RC and telemetry | ExpressLRS or Crossfire, MAVLink on | Same |
| FPV video | Your choice | Your choice |
Notes: Bigger antennas are always better for GNSS units.

F405 Wing Flight Controllers
While often considered a budget option, we do not recommend them as they do not store the full ArduPilot Image due to limited flash memory which cut meaningful features, such as Full HD OSD and Optical Flow. F405 are also limited in processing headroom and lack of redundancy. Choose reputable suppliers to avoid QA issues.

Choose once. Every motor and ESC below has a 4S answer and a 6S answer.
| Build | Lift motor KV | Pusher winding | Battery |
|---|---|---|---|
| 6S (the manual's values assume 6S) | Lower KV, see Lift Motors | 640KV | 6S 4500 to 5000 mAh LiPo, or 6S2P 21700 Li-ion |
| 4S | Higher KV, see Lift Motors | 900KV | 4S 6000 mAh LiPo, or 4S3P 21700 Li-ion |
<aside>
Mixing voltages is the classic mistake. A 6S winding on a 4S pack hovers weakly. A 4S winding on a 6S pack over-revs, draws too much current and overheats. Buy the whole powertrain for one voltage.

These are rough price estimates, not quotes. They were checked in September 2026 across the brands recommended on this page. The low end is typical AliExpress pricing, with about four weeks of shipping. The high end is typical EU shop pricing, with a few days of shipping. Prices, stock and exchange rates change, so check before you order.
