We are in the business of offering innovative aircraft instruments for light plane flying. As a result we often introduce new products for sale that are in the final engineering phase. Sometimes an engineering problem emerges in the final phase that delays our production runs. This means that if you are ordering a new product, we could be several weeks out from shipping. We try to keep our product pages up to date with shipping information.

As of December 2020, there are only two of us working Radiant instruments. We manufacture products in batches, and cycles take about a month. It is always best to order now and get on the list. We do charge your card at the time your order is placed.


We are now able to offer 2nd day UPS shipping on domestic orders, as well as USPS Priority Mail and an even lower cost First Class Mail. In some cases, we may need to revise you shipping amount, and will notify you by email of that change.

International Shipping: We ship internationally by USPS Global Express. We have a flat rate of $40.00. Other shipping methods may be used if you contact us for a quote.
