Moving the sensor in the same direction as the propeller rotation retards the timing.

I have 3 DLE engines from VVRC, a 55, 30, and 20. I have never made any adjustments to the timing from where it was set NIB. With the DLE20 positioned with the spark plug pointing straight down (six o'clock) the Hall sensor is right at the top (twelve o'clock). I am curious as to which way the sensor is moved to advance or retard the spark. Facing the engine does moving the sensor clockwise (to the right) increase or retard the spark.
Thanks
Mike
It will increase(advance the spark)timing if moved to the right/clockwise in your description.

Jody, Continued thanks on providing the best information on these engines!!

Question. Are the ignition modules fixed timing or do they adjust to the rpm? Then the would see 28, 35, or whatever degrees for low rpms before coming off idle. But if the sensor is off at idle, what would the advance be at higher rpms and could this damage a engine?

Was wondering if there was a way to hook a timing light up and see if it works off these small ignition modules.

Thanks, ML

I am not Jody but will attempt to answer your questions.
1)They adjust to rpm.
2)Whatever you set your timing to static is what will be at max rpm.
3)Rcexl ignitions retard timing at low rpm of magnet past sensor and increase timing as rpm increases(time between magnet passes sensor decreases)up to what was set static.
4)You could connect a inductive or direct coupling timing light but you would need to keep the ground circuit intact.As the shield(braid/ground) would prevent an inductive coupling from functioning you would need to connect an adaptor that would allow the emf to be radiated from centre conductor for the inductive pickup or fashion an adaptor to connect inline for the direct coupling type timing light,both methods require ground, that being the plug wire shield be kept continuous or in circuit.
Picture attached shows basic function of the Rcexl unit,do not take the max timing of 40 degrees shown in the picture as what your timing should be,it is an example of the timing retard function of the ignition module.

"Here's the deal with the timing, if you have one of the modules with #4 on it (stock DLE20) the timing is best at ~35*, if you have a standard Rcexl ignition with no numbers on it (says Rcexl on the module, not DLE) set it at 28*-30*. The module for the DLE20 has changed but even the original was set at 35*, personaly I prefer the standard Rcexl ignition at 28*. Either one will make the engine run very well but the #4 module will let the engine idle stupid slow, much slower than necesary.
"

Ok so I just got around to looking at my uninstalled DLE 20 today to see which off these I may have and now I am completely confused. On my ignition module is has both RCEXL and DLE on it. I do not see any #4 anywhere on the module and the serial number is 2489. So what do I have? Jody, you say it is either one or the other but mine has both on it. Not that it matters but is there another version now out there?

Thanks,

Joe

OK, I'll try to make this as simple as possible.

If it says DLE on the module, the module came with the engine, and the engine runs fine, leave the sensor alone.

If you replace the module with a standard Rcexl module not from DLE, set the timing at 28* BTDC.

That's all there is to it.

hope this makes it clear once and for all. This is a stock DLE/ Rcexl ignition that comes with the engine.

Looks just like mine. But I didn't know that these were set at 35 degrees until Jody made that perfectly clear.

Jodi,
You are correct do not need no instruction book.

Maybe Jody should change his user name to "jedijodyjob" or "jedijobjody" Try saying either of those 3 times real fast.[X(]

Is it OK to just take this engine out of the box and run it, without adjusting the timing and messing with all of this other stuff? This all seems to be overthought some. Especially if worried about the warranty.
Just run it. If it works, continue to run it. If it does not, then get it fixed. Easy enough.

That's what I did with mine. If your RPMs don't fall within what most people are getting for a given prop, then it would be time to investigate more - IMO.

OK Jody, as you suggested I pulled the plug out of the DLE-20 that has about 45 flights on it and put it in the DLE-30 that would not run. It was weird, it would not run, period. I swapped spark plugs from my older DLE-20 and it ran! Then I put in the new plug that would not run in the -30 and it ran fine in the -20! Whatever....

Got some great flying in this morning in the Bronx with my 70" GP Revolver and DLE20. Think I've finally got the DLE20 dialed in correctly - had to close the low end a tad and open up the high end another tad. Using an APC 16x8, and getting 1,700 rpm idle and 8,700 wot. Very good speed (though hard to be objective in a 15mph headwind...) and unlimited vertical. Did a couple of nice and high inverted "death spirals" today - got some good altitude first - then counted 20 seconds of spinning and falling! And after 20 secs of idle there was no hesitation on acceleration. And with that headwind the inverted hover just HUNG there! The gusts made for some interesting landings - but I like that - it keeps you on your toes. Love this plane and engine!
