Ignition Timing Adjustment The ignition timing is preset on the DLE-20 at 38-40° before Top Dead starting point.Center (TDC). The ignition timing can be advanced or retarded by loosening the (2) ignition sensor Phillips head screws and sliding the sensor to the full extent clockwise (41° advancing the ignition) or counter clockwise (37° retarding the ignition). Be sure to retighten the Phillips head screws after adjusting the ignition timing. It is best to attach the sensor with the screws centered in the slot as a I moved the sensor as far as I could to retard the spark, replaced the plug with a properly gapped new NGK CM-6, and checked the high tension lead. I'm ready to start testing tomorrow afternoon and see if these initial changes have had any difference. McD |

On small engines, a ignition timing of 15° to 22° will be plenty!!!!!

http://www3.towerhobbies.com/cgi-bin...?&I=LXANVN&P=Z Ran my engine yesterday and still have the miss. I guess the plug, timing, pickup lead, and high-tension lead were not the problem. I'll disassemble the fuselage today and dig out the battery, opto module, and switch wiring so I can bypass each one and see if I can find the faulty unit. Last resort will be to replace the whole ignition module with one from my DLE 30 that I have on hand. McD |

This is the official web site of DLEngines; http://www.dlpower.net/ Your quote came from the non-official DLE web info site which is in reality the Hobbico/Tower Hobbies site; http://www.dle-engines.com/index.html Their manual, while a lot more extensive, has it's errors too; Page 3 - Lawn Boy Ashless......very poor choice, far better choices exist. Page 7 - Dubro Vibration reducing eng mount....truly unnecessary for this DLE20. Page 9 - ..."deactivate the throttle return spring"....a personal choice, but that little spring puts very little pressure on a servo. Far better to leave it on there, as it will return your throttle to idle should your throttle linkage ever come off. The idle SCREW should be removed, as you do better controlling your idle from your transmitter, and with that screw out, you can more easily kill the engine if you need to. Page 13 - Ignition timing 38-40BTDC....waaaay wrong! 28 is correct. Those are the errors some of us have found Even though you may have purchased your DLE from your LHS -or- TH directly, don't feel too bad about not knowing the above things. They try fooling many, and now you know. Set your timing as close as possible to 28 degrees, and gap your new NGK/CM-6 plug to .020 and go fly!!! |

Good news, Bad news.
Good news is that I found the problem. Bad news is that the ignition module was the culprit. I replaced the module with one from my DLE 30 and the little 20 purrs like a kitten - not a miss to be heard.
Thanks for all the help and suggestions. This tread is wonderful for us newbies. McD |

Off your topic sorry. But can you guys tell me if it is okay to use a 6volt nimh pack on the DLE 30? Every buddy says no but the manual says Technical Data:
Ignition Battery: 4.8-6.0V NiCd or NiMH, 6.6V LiFe or 7.4V LiPo pack (LiPo or LiFe use requires voltage regulator.) Compression Ratio: 7.6:1 Gas/Oil Mix: 30:1 Replacement Spark Plug: NGK CM6 (DLEG5510) or equivalent Weight Breakdown: Engine: 32.1 oz (910 g); Muffler: 2.1 oz (60 g); Ignition: 4.2 oz (120g) I don't want to let the smoke out of the box I have the 4.8 on it right now and I am having starting problems??? Thank you and sorry to take you off topic. |

A freshly charged 4-cell NiMh battery pack will have 6.0 volts at the battery terminals. A freshly charged 5-cell NiMh battery pack will have 7.2 volts at the battery terminals.
I fly my DLEs with a 4-cell pack and don't have any problems. McD |

Thanks do you think it makes a bater spark with a higher voltage pack? Does the 4.8 have a weaker spark then the 6volt pack or does it not matter as long as the spark plug get the 4volt min? Thank you very much,
