Gone for Hamvention!We are out of the office for Dayton's annual Hamvention. Come see us at the booth!

Our sales and engineering team are out of the office this week for Dayton's annual Hamvention! We will be answering calls and emails remotely as best as we can and might not be getting back to you until the week of May 23rd.

Controller's are Shipping!

We now have all the parts for the electronic controllers in-house, and we anticipate rapidly catching up to our backlog. This will also have a significant effect towards reducing our lead-times for new orders.

We have had many challenges at SteppIR during these unprecedented times, and we are a very proud company as we emerge stronger than ever - we could not be in the position we are without you, our fantastic customers.

See you at Hamvention!
