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.

Shipping
Orders placed before 2 p.m. EST usually ship the same business day from Columbus, Ohio, by USPS or UPS, with most packages arriving in 2 to 5 business days. Orders over $100 may ship free within the US, excluding most airplanes, and LiPo batteries ship only by UPS Ground.
Returns
Items can be returned within 30 days of receipt with an RMA code requested by email. Returns in new condition with original packaging have no restock fee; others are charged 10 to 20%, and shipping fees are not refunded.
Warranty
Products older than 30 days may be exchanged under warranty but aren't eligible for a refund. Specific warranty terms aren't published in the policy text.
