Our verdict

A PP whoop frame with a 65mm wheelbase, for someone who has already picked the motors, flight controller and battery and wants the mounting sizes stated: 3 x M1.4 (6.6mm) for the motors and 25.5 x 25.5mm for the flight controller. Look elsewhere if you want a complete drone, a frame with a stated arm thickness, or a listing that names the parts it fits. The main caveat is that the listing says the frame resists crash impacts and adds approximately 5% more thrust, and these are the maker's own claims.

Best for
A builder planning a 65mm whoop who wants the motor mounting, flight controller hole and battery slot sizes stated up front.
Skip if
Your project is a complete drone, or you want a stated arm thickness or a frame that the listing says fits a named motor.

This listing is for a frame alone, not a complete drone: a PP whoop frame with a 65mm wheelbase and a listed weight of 2.65g. The listing presents it as a redesign of the earlier Air65 Frame, with four arm braces in place of six. The table gives a 3 x M1.4 (6.6mm) motor mounting, 25.5 x 25.5mm flight controller holes, an 11.4 x 6.2mm battery slot and maximum dimensions of 82.6 x 82.6 x 15.1mm. It costs $4 and comes in five colors.

Options and pricing

The listing shows five variants at one price of $4, and the only option is color: Black, Transparent Blue, Transparent Orange, Transparent Purple and Transparent White. The price does not change with color. There is a single 65mm wheelbase, and no other size, thickness or material option appears in the listing. The table repeats the five colors under Color Options.

How it compares

The Air65 Whoop Quadcopter-Racing,ELRS 2.4G is a complete drone at $105 with a 65mm wheelbase and a 17.3g weight, while this $4 listing is a frame alone at 2.65g, so the two do not replace each other. The drone's table names the Air65 Frame rather than this II version. The MIROKU Frame is $58 and lists titanium with a 5.0mm arm thickness, a different material from this PP frame, which lists no arm thickness.

Shipping and processing

  • Processing. The store's shipping policy says every order, including orders placed through the Shop app, ships from its warehouse in Japan and is dispatched within 1-3 business days after payment is confirmed (checked 2026-11-11).
  • Shipping cost. The policy gives a flat 800 JPY inside Japan and 5,000 JPY to eligible countries for parcels up to 2 kg, and gives no rate for heavier parcels. It does not list the eligible countries; the store's country selector offers the United States, Canada, the United Kingdom, Australia and New Zealand, and the terms of service reserve the right to limit sales to any region, so the checkout is the final test. At the rate the store used for US prices when we looked (about 0.00642 USD per JPY), 5,000 JPY is about $32; the checkout shows the exact amount.
  • Price against shipping. This listing costs $4, less than the flat international shipping fee above. The policy prices shipping per parcel up to 2 kg, so what an order of several small parts pays depends on how the store packs it, and the pages do not say.
  • Duties and taxes. The policy says import duties, taxes and customs clearance fees are not included in the price or the shipping cost, are charged to the recipient by the carrier (it names DHL, FedEx and Japan Post) and are outside the store's control. It declares the full value of the goods on customs papers and cannot mark a parcel as a gift or declare less. A parcel held for unpaid duties is not delivered, and if the carrier sends it back the return shipping is deducted from any refund.
  • Tracking. A tracking number is issued once the parcel ships. For international parcels it can take a few days to show up, and it can change when the parcel is handed from one carrier to another.

Returns and warranty

  • Returns. The store's refund policy gives 30 days after receiving an item to request a return. The item must be in the condition received, unworn or unused, with tags and in its original packaging, and you need the receipt or proof of purchase. Use the contact page first: if the return is accepted the store sends a return shipping label and instructions, and items sent back without a request are not accepted. The policy does not say who pays the return shipping on a change-of-mind return. Refunds go to the original payment method within 10 business days after the store has received and inspected the item (checked 2026-11-11).
  • Not returnable. The refund policy lists custom products (special orders and personalized items), perishable goods, personal care goods, hazardous materials, flammable liquids and gases, sale items and gift cards. The legal notice, which is in Japanese, adds made-to-order items, digital downloads once downloaded, and goods whose value was lost through the buyer's use or modification. For an exchange the policy says to return the item and, once the return is accepted, buy the new one separately.
  • Damaged or wrong items. The refund policy asks buyers to inspect an order on arrival and to contact the store at once about a defective, damaged or wrong item so that it can evaluate the issue and make it right. The legal notice says the store exchanges or refunds such an item at its own cost.
  • Warranty. The shipping policy, refund policy and legal notice describe no warranty, and we found no warranty page. The terms of service say products are provided 'as is' except as the store expressly states, disclaim warranties, and are governed by Japanese law. Many of the parts this store sells are made by other brands; nothing says whether the store or the maker handles a fault that appears after the item has been in use (checked 2026-11-11).

Before you buy

369DRONE describes itself as an FPV racing drone brand from Japan. Its About page says the founder, Daichi Sakakibara, spent over a decade as a test driver at Toyota Motor Corporation and builds products with experience from racing. These are the store's own statements (checked 2026-11-11).

The store is in Japan and quotes yen. The price on this page is its United States dollar price as of 2026-11-11; the store converts at its own rate, which moves, and a visitor in another country can see a different amount or currency.

The legal notice, written in Japanese, says the products are meant for FPV drone racing and hobby use, asks buyers to follow the Aviation Act, the Radio Act and other laws, and says the store takes no responsibility for damage caused by use that breaks the law. Those are Japan's laws. We have not checked what applies where you live and we do not say whether this product can be flown or operated legally in your country.

The English refund policy takes back items that are "unworn or unused", while the Japanese legal notice says, as we read it, unused and unopened, so check the condition rule with the store before opening the package. We have not read any independent review of this product or of the store.

What we liked

  • The listing gives the wheelbase (65mm), the weight (2.65g) and the maximum dimensions (82.6 x 82.6 x 15.1mm)
  • Mounting sizes are stated: 3 x M1.4 (6.6mm) for the motors and 25.5 x 25.5mm for the flight controller holes
  • A battery slot size of 11.4 x 6.2mm is given in the table
  • Five colors at one price of $4, so the choice of color does not change the price

Worth noting

  • The listing gives no arm thickness, so that fact is missing from the table
  • The listing says the PP blend resists crash impacts and that the arm redesign adds approximately 5% more thrust, with no test details behind either statement
  • Color is the only option; the listing offers no choice of material, wheelbase or thickness

Can I return it if I change my mind?

The refund policy gives 30 days after receipt to request a return of an unused item in its original packaging, with proof of purchase; contact the store first and wait for its return label. Custom products, sale items and gift cards cannot be returned, and the pages do not say who pays return shipping.

How long and how much to get it from Japan?

The shipping policy says the order ships from Japan and is dispatched in 1-3 business days after payment. International shipping to eligible countries is a flat 5,000 JPY for parcels up to 2 kg (about $32 at the store's US rate); the store's country selector lists the US, Canada, the UK, Australia and New Zealand.

Who pays import duties and taxes?

The recipient. The shipping policy says import duties, taxes and customs fees are not in the price or shipping cost, are collected by the carrier and cannot be predicted by the store. A parcel held for unpaid duties is not delivered, and return shipping is deducted from any refund if the carrier sends it back.

What we couldn’t verify

  • The listing says the PP blend resists crash impacts and keeps durability, and that the redesign adds approximately 5% more thrust; these are the maker's claims and we could not check them.
  • The listing does not name any motor, propeller, flight controller or battery that this frame fits, so fit is not stated.
  • We have not read any independent review of this product or of the store; the About page is the store's own account.
  • The English refund policy takes back items that are unworn or unused, while the Japanese legal notice says unused and unopened; we could not tell which rule applies.
  • The store's pages describe no warranty and its terms provide goods 'as is'; we could not tell who handles a fault that appears after use.
