Default Best glow driver?

Here's mine: It's a non-knocking plug heater made in Norway, check it out:
http://jonwold.blogspot.com/2008/08/...-glow-pro.html

Disclaimer: As you can tell from my blog post I know the guy who makes it but I have no economic incentive for posting this. I think it's a fantastic glow driver that will save plugs, engines and keep starting the 4-stroke beasts safe for everyone.

I post it here so that we can discuss glow drivers (I know there are more out there including Rcats from Central hobbies) and get feedback. What do you think of this glow driver?

It seems to be a nice piece of equipment! One question though:
Is it a true glow driver in the sense that it regulates the glow-plug current to compensate for varying electrical resistance of the glow plug, i.e., does the glow driver automatically increase the current when the glow plug is cooled by fuel droplets, or is it a constant current source?

Yes (or should I say Ja).
Here's a snippet from the manual:

"The plug power is continuously regulated to the preset power with regards to the battery voltage. Glow-Pro also measures the plug temperature and automatically adjusts the plug power to keep the temperature to the preset level. This makes the Glow-Pro uncritical to both sinking battery voltage and “drowned” glow plugs."

Looks expensive. Why would you need one of these compared to a plain old glow starter? I'm curious. Thanks

Call me crazy, but I just use an inexpensive starter from the hobby shop. [sm=confused.gif]

Until the advent of the YS DZ's there didn't seem to be much of a need for a delay glow driver, but I can tell you from personal experience that the delay feature is worth every penny. Prior to using one I had everything from happen from props loosening, to spinner cones wrinkled, to threads messed up on the crank/jam nuts, to the spinner back plate and thrust washer grinding themselves into little pieces of aluminum. The knock on initial ignition, even if it results in a successful start, can't be good for the crank pin, either end of the connecting rod, or the piston (to say nothing about the stress that initial whack can put on the front end of the plane even with a soft mount). I have heard about, but never seen, engine cowls being damaged by that kick. With a delay, most starts are extremely smooth; sometimes so smooth with the idle throttle matching what the starter is turning, only the change in sound will signify the engine is really running on its own. The one I have (similar to the one in discussion here) has adjustable delay timing as well as plug current. It was worth the cost. With a second person to punch a button, an option could be to have the other person fire up the glow plug once the engine is turning. Many times I'm flying by myself so the delay driver is great. Based on my experience and comments of others who use something like it, I would recommend using one.

My 2 cents worth.

The RCATS driver is really nice. It is still around 100USD but the delay drivers with the DZ's make life a lot easier. Not 100% necessary, as there are other ways, but I think it is much easier using the time delay drivers for the DZ's.

RCATS also has the option of a delay glowdriver, 5 seconds delay.

As Red B. from Sweden was asking, this (and some other glow drivers that are in the upper price range) provide a variable current to the plug so that the plug heat remains the same regardless of amount temperature, raw plug full of fuel etc. If you use a normal glow clip w/battery it's gonna start glowing immideately when its connected. That's not good for the plug, and you get the problem of backfiring. With these new generation of non-knocking heaters you can start spinning the engine before it starts giving current to the plug, eliminating the backfiring problem.

The driver I use is 1295,- NOK which is equivalent to 240 USD. It sounds expensive but the currency rate is very much in favour of NOK right now. A few years ago it would have been a $100 less but yes it is not cheap.

$240.00!!!!!! I've been flying glow engines for 30 yrs and I've never heard of or needed a delay glow driver. Glad I didn't at that price.

Have to agree with Rune on this one. I don't think you need to spend 240 for a driver either. There are others that work. However, if you arent using a delay driver and you get the dreaded DZ kick and it breaks the front of your 2500 pattern airframe. The 100 or so, or even the 240 seems cheap then. I personally use the NHP driver from Japan, and love it. There are other techniques that will work, however, the delay drivers definitely low this risk.

I get it. I knew the YS DZ engines were expensive but didn't know about the starting issues. You're right. I haven't used a YS and it's to late for this old dog to learn that trick.

Its not going to win over any clip starter fans, but the Radio South Pro Driver does everything the R-cats driver does for about $80. (Uses NiMh instead of Lipo.)

As i see it ...the delayed start off the glow and possiblity to adjust both that and the "glowing" is the big thing here.
It also let you use any type off battery you want ....you can change if you want dont remeber the volt it need.

The Radio South orange glow driver I have has a 7 second delay start.
It works great on the YS 170DZ.

I have the Radio South driver and I wanted to continue using it, because it has many advantages. So I put a simple lamp switch in the middle of the wire, I hold the switch in my left hand together with the landing gear and flip it On or Off when I want to.

Right...I think I have seen your driver before now.
My driver has the delay built in and is activated by the button on the driver....not in the wire.
So....I push the button, start cranking and 7 seconds later the glow comes on automatically and lasts for one minuite.
If the engine quits before the driver turns off, I just push the button again and the 7 second delay starts over.
