Radiant Solid-State Turn Coordinators for Portable and Panel Use
 
We've reworked our original Turn Coordinator to deliver fluid motion, crisp readability, and solid stability across temperature changes. You'll also see an 8-step pilot-selectable dimmer for day, dusk, and night.
 
You'll see a daylight-readable color LCD that shows digital yaw rate (deg/sec), a central aircraft symbol for turn direction, and a bubble-style roll inclinometer for coordination. 
 
It delivers crisp, high-contrast graphics, automatic dimming, and rock-solid reliability in a compact 2¼" package – now also available in a 3⅛" format for standard panels. No vacuum system, no moving parts, no drama. It gives you modern, solid-state turn information in three flexible formats:
 
  • SafeTurn Portable – Compact, battery-powered Turn Coordinator with “ball,” ideal as a grab-and-go backup or to move between aircraft. Internal battery and typical runtime, making it truly portable (no panel mounting required). 3⅛" holster for mounting is available.
  • 2 1/4" Panel Turn Coordianator
  • 3 1/8" Panel Turn Coordinator 
These are both ship-powered panel-mount units designed to drop into standard instrument holes as a modern replacement for legacy vacuum or electric gyros. They have the same internals, just different bezel sizes.
 
All three share the same solid-state sensor core, neon-blue LCD graphics, and a clean two-button interface, so once you’re familiar with one, the others feel instantly natural.
 
Available in three versions
 
 
How it compares (past generation to now)
  • Motion: it was stepwise; now it's silky.
  • Legibility: better, smoother appearance in every detail.
  • Stability: tighter temp comp.
  • Configuration Options: Set the Gyro rate as ultra-fast to molasses slow&smooth.
  • 8-step pilot-selectable dimmer for day, dusk, and night.

Looking for a mini glass panel with Turn Coordinator, Altimeter, VSI, and optional ASI (0–220 kt / 0–250 mph)? See our Mini Glass SafePanel instruments.
 
We're introducing our new Mini Glass SafePanel, which uses the same core products as the Turn Coordinator, but adds an Altimeter and a VSI to our Turn Coordinator (2 1/4" and 3 1/8")  versions, with backup battery that runs when ship power is dead! 
 
 
This is a great value for home builders and an excellent choice to install beside far more expensive, high-dollar glass instruments as a backup. This product is designed for use in experimental, ultralight, and Light Sport aircraft (with manufacturer approval).

  • Any pilot who has ever wanted to add a turn coordinator to an experimental aircraft panel has been put off by the complexity, weight, reliability, and price of traditional electric or vacuum units.  The Radiant Panel Turn Coordinator solves these problems.

     

    Compared to all other Turn Coordinators, this unit also provides a digital indication of degrees-per-second during the turn.  It is also inexpensive.

     

    It utilizes a solid state gyro and accelerometer, weighs less than 2 ounces, attaches to any aircraft ship power system, and allows for easy in flight calibration at the push of a button.

    The unit graphic design looks exactly like existing turn coordinators, so there is no learning curve for the pilot. Also, unlike some products, the unit’s gyro will stabilize even if brought to power under aircraft upset conditions.

     

    What's new (and why it matters)

    • Higher frame rate = fluid motion. The airplane symbol and bubble now move with smoother step, so trend and magnitude are obvious at a glance.

    • Smoother graphics and fonts. Refined anti-aliasing and subtle dithering—our neon blue theme—increases perceived resolution and legibility.

    • Intuitive power watchdog. Simple green/yellow/red indicator provides a warning for power droop.

    • Selectable Gyro Filter (0–3). A brand new idea and feature! Tap both buttons to choose response: 0 = snappy/aerobatic, 1=normal, 2= slow, 3 = molasses smooth & slow.

    • Improved temperature compensation. Updated model to keep the digital yaw centered as cockpit temperature changes.

    • Clean two-button interface. Left button = DIM (short press). Right button = CALibrate (long press ≥7 s). Both buttons (short press) = Change Filter, from levels 0–3.

To Our Customers

We are in the business of offering innovative aircraft instruments for experimental aircraft flying, and backup / CO instruments for general aviation (non-TSO/non-PMA). The instruments from Radiant Technology are not designed to be used in applications where their failure would endanger safe flight or human life in any way. They are intended solely for use in VFR conditions. They are not certified to meet any Technical Standard Order, and are not produced under a Parts Manufacturing Authority (TSO / PMA). As a result, they are suitable only for use in experimental and ultralight aircraft, and in Light Sport Aircraft, if meeting the requirements of the respective manufacturer.

Support

If you need support for your Radiant instrument purchase, please contact us by email at support@radiantinstruments.com. Because of our small staff, we do not have a direct phone number.  We do our best to respond to emails as soon as possible. If you do not hear from us within 48 hours, please try again. You may also try kathy@radiantinstruments.com. Please check our our Warranty Information here.

Shipping Information

Since we offer innovative aircraft instruments, 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 2025, 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 ship by USPS Ground Advantage. We do not ship internationally, but our distributor, Aircraft Spruce does. Please order at https://www.aircraftspruce.com/. Search "RADIANT" and most of our products should pop up.
