Buying FPV drone parts is easy until you order a 2S motor for a 1S flight controller. The cart looks fine; the craft never arms happily. FPV Grind’s buying path is compatibility-first: pick a class, lock the radio link, match cells and connectors, then add consumables that actually ship in India.
Use this page as the order-of-operations. Price shape: how much FPV costs in India. Whoop-specific stock notes: tiny whoop parts India.
Buy in this order
- Decide the craft class - indoor whoop, outdoor whoop, or 5-inch. Do not mix shopping lists - which build first.
- Radio first if you are new - an ELRS radio outlives airframes. Practice in the free online FPV simulator while you wait for shipping - what is ExpressLRS.
- Airframe path - kit/BNF for speed, or parts list in Grind Lab for a scratch build.
- Batteries and props last-but-same-cart - you will need more of both on day one. Batteries ship surface-only in India.
Same-cart minimum for a whoop start:
□ Craft (kit or BNF)
□ Radio if needed (ELRS)
□ 4–6 packs matching connector
□ 2–3 prop sets
□ Charger story that matches cells
□ LiPo bagCompatibility rules that save returns
| Pair | Must match |
|---|---|
| Radio ↔ receiver | Same link (ELRS ↔ ELRS) |
| Battery cells ↔ FC/ESC | 1S with 1S, 2S with 2S |
| Connector | BT2.0 vs PH2.0 on whoops - connector guide |
| Prop size ↔ frame | 31mm / 40mm / 45mm must fit - pick whoop props |
| Motor KV ↔ cells + props | Wrong combo cooks ESCs - KV vs prop |

Kit vs BNF vs scratch (buy decision)
| Path | Buy when | Watch for |
|---|---|---|
| Kit / RTF | You own nothing | Radio quality; confirm ELRS |
| BNF | You already have ELRS | Goggles + packs still needed |
| Scratch | You want repair skill | Soldering + config time |
BNF cost shape: BNF vs PNP vs scratch. First whoop picks: Cetus vs Mobula · buy tiny whoop in India.
Domestic vs import
Start domestic for consumables (props, packs, screws). Import only when a specific part is unavailable. Full notes: import vs domestic FPV gear in India and the buying checklist.
| Buy domestic first | Import only if needed |
|---|---|
| Props, screws, soft mounts | Rare AIO / HD stack |
| Whoop packs (plan lead time) | Specialty frames |
| Common ELRS radios / BNFs | One-off mentorship gear |

What ships slow / what grounds you
| Item | India reality |
|---|---|
| LiPo packs | Surface shipping - order early |
| Props | Usually fast domestic - still stock spares |
| Niche HD / specialty | Import waits + duty surprises |
| “Compatible” mystery radio | Orphan protocol = dead end |
How many packs: how many LiPos. Charge/store before the first weekend: safe charge · storage.
Cart mistakes that waste money
| Mistake | Result |
|---|---|
| Mixed PH2.0 / BT2.0 | Nothing plugs in cleanly |
| 2S packs for 1S AIO | Dead or dangerous mismatch |
| One battery “to try” | One crash ends the session |
| Non-ELRS orphan radio | Bind pain forever |
| 5" parts for a whoop dream | Wrong class, wrong noise budget |
| Skipping Grind Lab on scratch builds | Incompatible stack |
Validate scratch lists in Grind Lab before you pay.
