Default Starter Question

I have a Sullivan Dynatron starter with a Miller reduction belt. Ordered 2 of the 12V starter packs from Hobbico. There real junk.... won't even hold a charge for one start. (using to start a DLE55 and DLE30). Have since bought 2 Sullivan packs (which they don't make any more, but the batteries are toast. Can someone tell me where I can the batteries for these packs and another charger unit. I'll need 12 batteries for each pack. Thanks for any help

No, no go straight to your local hardware/tool store and order a Black @ Decker 24 volt nicd drill battery pack, This pack is already made and provides the optimum voltage for the Dynatron to provide awsome performance. The Nicd cells have the ability to give up a lot of current without damage Also they are not seriously affected by deep discharge which is why I shy away lipo's for starters. This becomes very important when your starter is the most popular on the flight line.

I love my Dynatrons and have two one is direct drive and I can alternate between a one inch cup as well as a quickly removable two inch cup. The other has my home maid gear drive and this one has a three inch cup. It depends on what I am flying as to which I will use and for the smaller stuff I will use the 18 volt black and decker drill battery but the geared starter with the 24 volt battery has no problem with my OO 55GT and my G-62. The direct drive Dynatron with the 24 volt Black and Decker has not problem at all with my OS 33.

The starters use Sub C size batteries. There are many places to get them on line.
There is also room to put 2 2S1P LiPos in there.
You will need to configure them for series when running and charging each one separately.

I'm not disagreeing with John, just pointing out options.

Good Luck,

Why not ditch the starter and hand flip those DLEs,, Mine start pretty darn easy by hand.

I use the same starter/drive as OP and simply attached a flat four cell A123 battery directly to the starter. No wires, relatively light and it would start my DA 100 NO problem.

The OP's starter is a Sullivan Dynatron which is a 24 volt starter system and a five cell lipo is going to be what something less than 19 volts? Decidedly lethargic. Any battery chemistry that is going to be less than 24 Volts is going to be disappointing for the bigger stuff and certainly not insane.

The Black an Decker makes a heck of a lot of sense for the Dynatrons and boy do they work , yes they are Nicd's and yes you need to charge them every time you go out (I would not do otherwise with any battery system). And they are reliively cheap you do not have to deal with assembly of a bunch of loose cells and if ya don't have the drill then just pick up the B&D charger or like I do use one of my two Venom Plus chargers which I charge just about everything with and are rated for 20 cells or 24 volt.

As far as hand propping of my larger engines, well no thanks although I have done it out of my wheelchair its a challenge but using my appropriate starters it is not.

Yup lots of choices! ain't that Cool

John

John, I had that same starter set up and ran a single 12 volt motorcycle battery,, it turned over my quadra 40 no problem,, full 24 volts isn't need IMHO,,

Maybe you know something I don't but the OP didn't mention he was wheelchair bound also or handicapped in anyway. Not sure why you have to find opposition with any opinion but your own, No one was talkng about your unique situation, As we all know, hand flipping these is the common procedure at fields everywhere.

Sorry I offended you that was certainly not intended. What I did intend to point out was that the OP was using twenty four volts and any other battey type that was less than 24 volts would definitely be a disappointment to him its that simple.

Not everyone hand starts for many reasons.

So I will refrain from posting on this thead any further thanks.

John

How do you keep the contacts on the starter button from sticking?

If you open it up you can see where the brass gets build up from transfer at the contact point. This is from the heat/arch of electricity and causes a small amount of brass to stick to one side. The part that has stuck has been annealed so it is softer and causes the sticking, either file the transferred part back off or replace the piece altogether. I file mine off several times, before it becomes necessary because of loss of material, to replace the brass. A spot of electrical grease slows the arching down as well.

John: I see you have a "home made" gear drive on your Dynatron. Just curious, "where did you get the parts/assembly etc. from" I've got a Dynatron and was looking into a Miller, but, if there are other options out there, I will certainly look into it.

Thanks
Mike

Hi Mike sorry I was late in getting back to you. Yes my starter is a home made system that was first devised by a gentleman who was intending to sell them actually many years ago now. He finally retired from modeling altogether and his original prototype was snapped up by another local flyer and when the other local said he had parts for more of them I immediately connected with him and was able to buy all the parts to put one together except the cover which I later cobbled one up.

I am sorry I know that is not what you want to hear since I cannot answer your questions as to a gear source etc or even what the actual ratio is.

John

John: Thank you for breaking it down so I could see the inter workings. Really not that "technical" to what a person is trying to do. I am going to keep your response in one of my "I shall build it" favorites and work off of that. By the way, I really like your cutting mat, it shows that your "doin' your thing" aka, a lot of wear.
Thanks again.

Mike
