Delivery Address

Terms and Conditions

1. Pre-orders

AeroTech estimated delivery: September 2027. Your item ships in our annual shipment from AeroTech, expected around September 2027. This matches AeroTech's advertised 44-week lead time, and we expect most orders to arrive then.

Delivery is not guaranteed. AeroTech's lead times have exceeded their advertised times before, and in the worst case we've seen, an order took about 2.5 years to arrive. If your item hasn't arrived after the 2027 shipment, you can choose to keep waiting or take a full store credit for the undelivered amount. If it hasn't arrived within 30 months of your order date, you can request a full cash refund of the undelivered amount.

LOC orders have typically arrived about 1 to 2 months after we place them. Busy periods can stretch this, but it is highly unlikely to exceed 4 months.

We expect Estes stock to arrive around April or May 2027. We have never ordered from Estes before, so this timeline is based only on what Estes has told Endeavour, and it could take longer.

If, for whatever reason, you have not received your LOC or Estes order by the end of 2027, you are entitled to a full refund or store credit.

2. Store credit

Store credit is issued to the account or email address used for the order and can be used on any future purchase in our store. Store credit does not expire and cannot be exchanged for cash, except where required by law. If you have issues viewing/applying your credit feel free to contact us via chat or email at sales@endeavouraero.com

3. Delivery and launch site pickup

Choosing Postage Delivery or Launch Site Pickup when you place your order is final, and you cannot switch between the two afterwards. Items for launch site pickup are only delivered to a launch if they have been assigned to that launch before the cut-off shown on the product allocation page. It is your responsibility to assign your items in time. This must be done in addition to selecting your pickup location on the current page.

4. Dangerous goods and safe use

Our solid rocket motors are classed as dangerous goods or explosives and are subject to strict laws on storage, transport, sale and use. By ordering, you confirm that:

  • you are legally allowed to buy, possess and use the products in your state or territory, and you meet any age or licensing requirements;
  • you will store, transport and use the products in line with the manufacturer's instructions, applicable laws and the rules of the launch site or club you attend;
  • the products will only be used for their intended hobby rocketry purpose; and
  • you will not on-sell or supply them to anyone who is not legally permitted to have them.

We may cancel or refuse any order, or hold an order until we can verify eligibility, if we reasonably believe these conditions are not met or that supply would breach the law. In that case we will refund or credit you as required by law. Some products may be restricted or banned at certain launch sites, and it is your responsibility to check the rules of the club you plan to attend.

5. Pricing and availability

We try to keep prices and stock levels accurate, but errors can occur. We may cancel an order affected by a pricing or stock error. We will contact you and will refund or credit you for any amount paid for it.

6. Liability

Hobby rocketry carries inherent risks. To the extent permitted by law, we are not liable for loss, damage or injury arising from the storage, handling or use of products after they have been delivered or collected, or from failure to follow instructions and safety rules.

7. Your rights under Australian Consumer Law

Our goods come with guarantees that cannot be excluded under the Australian Consumer Law. Nothing in these terms limits those rights, including your right to a replacement or refund for a major failure and compensation for foreseeable loss or damage.

8. Changes and contact

We may update these terms from time to time. The version in effect when you place your order applies to that order. Questions can be sent to sales@endeavouraero.com.
