Onboard Glow Plug Driver GDL V6.9

  Thank you for interesting our extremely lightweight robust and easy to use glow driver system.
GDL V6.9 was designed to eliminate the need of external handheld glow igniters or start panels, traditionally used for starting methanol (nitro) engines of fixed wing RC aircraft. Heart of this device is a specially designed converter that gently conforms the 2S LiPo battery voltage to any standard RC two or four stroke methanol engine's glow plug. Upgrading your aircraft with this device will allow you to totally control your engine's glow plug from your transmitter. By your choice, the glow plug can be remotely turned on, off, or automatically controlled by throttle stick position.

Technical characteristics

Every item passes six steps of QC. The final stage is Real Load Test that we perform right before packing. There is no any chance for faulty device to pass out our factory's door.

Engineering over marketing

  You presumably may say, that the perfect glow driver must have a button to set it up, a button to turn it on for engine start, a switch to turn it off after the flight, and several LEDs to see when you lost connection with the plug, when you need to charge the battery, when you shortcut the plug's cable, and of course, the most important LED-of-pain called "Your Plug Is Dead". Oh! Don't forget the battery cutoff and overheat protection! And... as a cherry on top, a complicated paper manual, making the whole thing useless if it lost.

 Do you really think you need all this? Or maybe sales guys do? It's not a secret that it's way easier to sell something fancy looking over really cool engineered.

 Face it, the only thing you really want from onboard glow plug driver is that installation should take not more than couple of minutes and after this, you'll get a couple of things less to care about. Less, not more! Since you install it, it must work as expected till the moment you'll decide to reinstall it to the next model.

 Honestly it was not too easy to achieve this, but we did it finally. It took about 10 years of research and real life testing. Just check the following "In details" section to find out how it works.

In details

  First, we need a perfect electrical and mechanical connection with the plug. As it usually happens, there was a very long way to find the perfect solution that is pretty simple and obvious. Unlike traditional plug caps (weak or oversized or both) our clip consists from only one small part and this is just a specially shaped piece of thick and strong springy wire. It's easy to clip it on and there is no any chance that it will unclip by accident. The electrical contact is perfect too, cause the physical tension is really strong. Also it's a spring loaded connector that is paramount for high vibration environment applications such as small engines.

  Next, we need a really good wire. We use military grade fluoroplast insulated ones. Its sheathing is hard to cut even by knife and thermal endurance is enough to stand the hot soldering iron or even open flame. It's way thinner, lighter and tighter than traditional silicon wires, while the same soft to bend. We wrapping the tip of the wire over the clip and then soldeing it. The second "ground" wire is the same, with the exception of fork connector for motor mount screw at the end, instead of plug clip. It's a real overkill for any real life situation.

  And finnaly, we have to connect with the electronics. Here we use the industrial microlift connector produced by Degson Electronics Ltd. It's really small and lightweight but incredibly durable. There are two the same connectors in GDL V6.9. One for glow plug and another one for the battery.

 Bingo! Now we're free from contact-related troubles. You really have to crash your model into dust first, to break this kind of connection. Say good bye to several annoying LEDs and related "so necessary features".

Let's dive into electronics!
Just one boring fact first. Unlike almost any modern electronics, this device is not fully digital. But it's not fully analog either! We use semi-analog tech based on non-standard utilization of every single part parameters and even more their stable imperfections. It's far beyond the typical applications described in manufacturer's datasheets. The basic principals are: "more features with less parts applied", and "all features must be based on physical laws, not by adding special circuits". Finally we've got simple device with lots of features that never fail, while the laws of physics are unchanged in the universe.

 OK! Let's jump to funny stuff!

 As we already know, our GDL V6.9 does not have specially added protection circuits, but!

Thus, the only LED you need is one small but very bright one that will show you if your glow plug is on or off. You'll use it maybe ones or twice, during initial adjustments, so there is no need to drill the fuselage for it. Speaking of drilling, the only fuselage modification you may need is a tiny 2mm (1/12inch approx.) hole under the hood, for two thin wires that even has no connectors on one side. (Thanks to Degson's the GDL equipped with.) And finally, all installation operations can be performed with no soldering, and with almost no any additional tools, right on the field!

Quick Start

THE GOAL HINT: The LED on the Glow Driver board works only when the plug's battery is connected. It's a good point to connect the battery but NOT connect the glow plug while performing the initial settings, cause fine adjusting radio's mixer can take a while and there is no need to heat the plug all this time. Don't forget to connect the plug after all initial adjustments are done.
