Buying from Buddy RC

Buddy RC is a strong pick for RC pilots who need specific parts, power systems or helicopter spares from a US warehouse with same-day dispatch. Skip it if you want generous returns, since shipping is never refunded and returns that aren't in new condition carry a 10 to 20% restock fee. Confirm the exact part number and motor or frame compatibility before ordering, because most of the catalog is model-specific.
