DLA Engines

6v is going to be way better to operate at then the 4.8 for sure! I see the new DLE ignitions are labeled for the specific engine. I have a feeling that they have been working on the timing advance specific to each engine.

that must be due to some of the internals in the ignition because when I worked at DA our ignition did not give a hotter spark for a voltage change.

I've heard this too. From what I understand with Rcxel 6v is preferred but over that it generates heat in the ignition itself which can shorten it's life. That was before they became rated for 2s Lipo though. Again, I'm no authority on it though, just heard from credible sources.

.....the airframe finally arrived today. Whoo hooo!!!!

Come on Rob,

You've had your new toy for a while now and you STILL haven't posted any pictures yet. What are you going to do, leave us all hanging AGAIN ! ? ! ? ! You ought to be ashamed of yourself...................

P.S., Don't you just love a smarty pants?...........................

So does anyone know who is making the DLA ignition or is it there own? It is in a black case and you can clearly tell there is a LARGE capacitor in the case... Just curious

Call them and see or call the DLA rep. Sounds if he would be happy to answer your questions from what @stangflyer has said.

@ChickenBalls IMO and knowing how Ohm's law addresses electrical matters.....I would be more concerned with lower voltage causing my ignition to run hot than with higher voltage. Think of it as supply and demand where efficiency is greatly diminished and demands more energy but ends up exhausting what energy is available through heat loss (BURN OUT).

On DA ignitions my guess is that they have a "fixed" value resistor on the input side of the circuit that is nominal to voltages between 4 and 8 volts dc instead of large input capacitors.

Sorry. Not meaning to keep everyone wondering. Just been lots of hours at work lately. Pretty much done by the time I get home. I will get the motor mounted tonight and hopefully post a few photos.

No sweat Rob. Trust me, I feel your pain, but I look at it this way. The harder I work during the week, the better I feel when I get a chance to "play" on the weekends.

Sorry for the wait everyone. It's been a bit of a long week. But I did get off early today. Which allowed me the time to test mount the 128 quad to the intended airframe. I wanted to keep the airframe under wraps for a little while as I plan to do something kind of cool to it. (At least I think it will be cool) But unfortunately it is revealed while test running in the motor. Oh well, I still plan to do something kinda different with it.

That being said, I ran into a few little hiccups with the DLA after getting it mounted. Not the motor at all, but subsequent components attached to the motor. My advice? Take them DLA Iridium plugs and chuck them as far as you can. They are truly just about worthless. I got little to "NO" spark from them on one ignition module. And ZIP on the other. Come to find out, Hiccup number two turned out to be a bad ignition module out of the box. Course this was discovered after my son @Shayne Epley and I flipped on that Falcon 28x10 for about an hour. We'd get a couple of "pops" and then nothing. I can always count on my son. He has not mounted his new DLE 111 yet so he ran home and grabbed his ignition module from that motor. Mounted it in place of the dead DLA module, replaced the DLA Iridium plugs with genuine NGK CM6's and what do you know? This little guy sparked to life almost instantly. A little difficult to get going at first, but once the needles were set right, away she went. So that would be hiccup number three. Don't trust the factory needle settings. Also, it would be my opinion, that DLA needs to revisit the ignition modules they supply. A DLE twin is a direct swap out replacement. I would think the RCExel also would be a great replacement module.

I am uploading a video of the second run right now and will post it here as soon as it finishes. In the meantime, I will say that the more that little motor that "can" runs, the better it gets. After the fourth and final run, I was up 150 rpm from initial start up rpm. Idle was basically smooth as glass from first start up. Last run with the Falcon 28x10 was just over 6300. I am feeling really positive once I get a couple of tanks through the motor and the Bowman rings installed, it will have no problem spinning that Falcon 29x9W at a good head of steam. Throttle response is snappy and crisp. Top end is like a Ferrari. All in all, I am actually quite pleased. Now all I need to do is find the time to get the plane built and the unique scheme done on it.
