DLA 56 help

[BlackRain]

Hi ... I'm new to the gas engine stuff so some of my questions may be really newbish so I appologize... but no such thing as a stupid question.

I have my engine sitting on a break in stand and since the manual tells you pretty much nothing about how to set the thing up this is where I need some help.

I have the spark plug wire figured out and pretty sure I have the battery one figured out (black & red) but what are the other two multi colored wires for?

I have read that you should use a 4.8 v battery for the ignition system ... but mine says to use a 7.2-8.4 v lipo battery. It says this in the manual and again on the ignition box itself... which is true?

I purchased a 7.4 v lipo for it but don't want to install it for fear of frying something.

Any help would be greatly appreciated.

Thanks,
BR.

With the Lipo you would need a regulator to bring down the voltage. Use a 2 cell 123 with no reg. Hope this helps. Phil

DO NOT use anything over 4.8. Everyone seems to think that more volts means hotter spark, and longer battery life - WRONG. Get a good 3000 mah 4.8 battery, buy yourself a good battery charger/discharger, USE the recycle on the charger at least once a month, and you shouldnt have any issues. Do not turn over the engine without the ignition system all hooked up, or it could back feed thru the pickups and fry your ignition. Take the ol lipo, and throw it over your shoulder to the dog. Happy flying :)

May I be so blunt as to suggest you ask the retailer that sold it to you what they would suggest. Seeing they are the ones that you will be dealing with if you encounter problems.

Lipos arent all that great. Theyre unstable. Actually, VERY unstable cells, thus the explosion hazard. niMh or nicad are good ol batteries that have proven themselves in the test of time. I know that most engine manufacturers say 4.8 or 6.0 volts will work, but Ive heard of WAY too many horror stories about 6 volt guys frying their ignition modules. 4.8 is fine like I said, just get a good one. JR sells some good products via sanyo. Give my advice a shot, and prove me wrong :) I know you wont, but hey, a good challenge is always good for future reference!

Thanks for the info guys... much appreciated... here is where I am at so far... a friend brought over another CDI... from another engine he had.. list was 4.8 v to 6 ... hooked it up and the engine fired right away... didn't stay running as we were getting too many air bubbles in the fuel line from vibration and a longer than normal fuel line from the tank..lol. But none the less it did fire up...
Upon further inspection of my lipo battery today I found that it was not fully charged... so I have charged it up and will be trying the factory CDI again later this week as time permits. I will post up the results for you guys here.

As for customer support I fully agree that these over seas dealers need to get something set up over here as far as customer support goes. I am looking into opening up a hobby shop with a friend and this is something that I will be taking a very close look at in dealing with these engines... maybe a good owners manual would be something to suggest to these folks in the way of trouble shooting.

Cheers,
BR.

DLA uses 2 cell lipo battery for ignition. don't need any regulator or anything else. just connect a 2 cell 7.4v lipo to your ignition if your ignition has black box and says 7.4-8.4! dla works much better with its own high voltage ignition. don't touch anything on the engine (no adjustment needed). if it doesn't starts easily, use a starter. a good starter can turn your 56cc. it will be running fine after a gal of fuel.

Here is the manual for the DLA engine.
http://www.greathobbies.com/manuals/d/dla/dladla56.pdf

Look at page 3.

It calls for no more than 6V. That being said, you should use a 4.8V battery. These batteries fully charged are around 5.6V which should be plenty for your engine. 4.8V @ 1500mah would give you a full day at the field.

One thing to correct though is that you can use a Lipo battery if you wish with a regulator set at 5.5V. Lipos are not "unstable". I have been using Lipos for many years, for my receivers all the way to ignition modules using quality regulator and decent chargers and never had an issue, not even a battery getting warm.

I also use lipos in high current setups for my pattern airplane and again. It is a well proven setup that works awesome.

You can go either way, to simplify things I would use a NiCd or NiMh 4.8V @ 1500-2000mah. It will keep the weight down and it will work great.

Cheers,

Both my manual and the CDI both call for 7.2-8.4 volt lipo.... this is the upgraded cdi from DLA not the gen 1 version. I will be testing the new ignition with another proven Lipo battery again soon.

I have 112cc of the same engine. it only starts with its own 7.4v ignition!

No way should you need a starter, and as soon as it fires up start tuning, don't run it rich, no such thing as factory settings.
