Mitsubishi MU300 Diamond Parts Available

Industry Leading 90-Day Money-Back Guarantee

You may return parts or request a replacement within 90 days of the purchase date with no penalty. We'll also pay the return shipping costs if the return is a result of our error (if you received an incorrect or defective item, etc).

We do not accept returns on anything marked CORE, Fuselages, or anything stating "No Returns Accepted".

If the return is past 90 days from the date the item was delivered, you may incur a restocking fee. Each return is handled on a case-to-case basis, and we do our best to be fair and reasonable.

Once we receive your returned parts, you should expect to receive your refund within a week or so. In most cases, you will receive a refund quickly.

If you need to return an item or want a replacement, fill out the form HERE with your order number, details about the product you would like to return, and the reason for the return. We will respond quickly with instructions for how to return items from your order.

Our 90-day guarantee is our commitment to treating our customers honestly and fairly. We put every part through a rigorous process before we make it available for sale. Despite our best efforts, sometimes we do not have the capability to test certain items, or we might miss something during the inspection process.
