Re: LiFe on ignition

Gary, no apologies needed. A little discussion is healthy.

From what I have gathered so far, a 6v nimh at full charge is around 7.4v. At 7.2v full capacity, a LiFe pack falls into that "safe" range. LiPo on the other hand would need a regulator to be safe. The printing on the ignition box and the instructions do contradict each other which adds to, I'm sure, burnt out iggy's.

I will use a Leopard Power 1750mAh LiFe from Pro-Rc unregulated on my new 35 on it's own switch.

Re: LiFe on ignition

For what it is worth - here is my experience:

Check the voltage rating on your actual ignition module (not the manual) - the DLE35RA has been around for awhile, and I know of at least 3 different ignitions that it has shipped with. Early in the DLE35RA run, they shipped with ignitions rated at 4.8v - 6.0v. In the case of these ignitions (RCEXL), the rating is very specific. So if your ignition is rated for a max of 6.0v - that means it can handle a voltage of 6.0v - NOT 6.1v or 6.2v or 6.6v. For these ignitions, a 5cell NiCAD/NiMH or a A123/LiFe is too much without a regulator. If you run one of these ignitions at 6.1v (or higher) you will prematurely kill the ignition - it may not die on the first flight or the tenth flight - but it will die before its time (we have replaced many of these ignitions because of this - we are an RCEXL reseller - and yes I have seen an ignition fail by over voltage on the very first engine run).

Newer DLE35RAs have newer ignitions that are rated for higher voltages (some will be 8.4v and the newest will even be 12v) - again the actual ignition module will list the rating. Do not exceed the rating.

Your manual may not correspond to the actual ignition module (they rarely update the manual). Also - don't assume that a "brand new" engine will have the newest ignition module - sometimes there is old stock, sometimes the manufacturer won't use the "newest" ignition on a specific batch of engines. Check the rating on the ignition.

Hi guys. this is what I found to be the best way on mine ignition to guaranteed there's going to be no issues. I use one battery at 3600 amps. Life battery which is a 6 6 volt.I run one switch to my receiver and 1 switch to my ignition through a optical kill a voltage regulator set at 5.2 volts. I run 645 and 5645 Hitec servos on my 30 cc and a 50cc. Had no issues whatsoever.I do like to try to keep it as simple as possible.

hope this helps.
