Sonic-Troincs 4.8V Pulsed On Board Glow Driver - Five Cylinder.
How do I select a battery pack for the Sonic-Tronic / McDaniel’s glow drivers ?? May I give you a quick way to answer them. This applies to any of our glow drivers MCD471 thru MCD479. ( The MCD466 is an exception as it has a built in battery pack and does not apply to the following information. ) Simply supply one (1) amp or 1,000 ma for each glow plug. Example, a five cylinder engine has five glow plugs and will require 5 amps or 5,000 ma’s. A 4.8 volt pack is the required pack voltage and should supplied from a NiCad or NiMH battery pack having 4 cells. ( NO LIPO cells with or without regulators can be used )
In the case of a 6 thru 9 glow plug engine we suggest a 5000 ma pack which is normally adequate for a full days operation. Keeping in mind this type of model will have less flights in a day so why have a larger, heaver battery pack in the model than what you’ll need. The glow driver only requires power from the pack for starting , idling and low speed operation. The engine at high speed does not require external glow plug drive as it’s running quite well.
An important fact about our glow drivers. A normal glow plug connected to a single (1) cell will require about 3 to 3.5 amps to properly light. Using our Electronic Pulse Glow Drivers you only need one (1) amp to light the plug properly. If our driver was not on board the model and it had a nine cylinder engine can you imagine a 9 x 3 amp or 27 amp battery in the model. I don’t think it would get off the ground.
