Sullivan Dynatron Starter


If I hook up my Dynatron starter to 24v, will it work on a DLE55?

Maybe. But get ready for super fast spinning. I find 24v a chore to control and have seen others have the same problem. I have used a milwakee 18v battery drill with a 3" spinner insert to start G62's and DL50's. 18v might do you better if there is an easy way to do that. My dynatron easily starts my crrc40cc with a 12v garden tractor battery. Never tried my DL50. You might try a bigger 12v battery just for grins and see what happens. I know if you have a small battery that dynatron can suck a LOT of juice and bring a 12v gel cell to its knees. Just my opinion.

Agreed...I think what you need is more cranking amps. A 12V. "Garden Tractor" battery from Wal Mart (or equiv.) is relatively inexpensive, and will allow the Dynatron to give you a LOT more torque that a small "motorcycle" size battery.

I have a Dynatron that I occasionally use w/ 2X 8 cell 3300 NiMh packs which give me lots of R.P.M. but what you need is torque.

I am currently running the Dynatron on a 12v gel cell and, the battery holds up fine but, then again I am only using it on my .91 size glow engines. I am adding another 12v battery in series to my flight box to get the 24v. I will try it first on my 26cc SV. I will let you guys know how it does.

Careful with plastic spinners. I melted one on 24v.

Thanks, I only use aluminum spinners. I gave up on plastic spinners when I saw a pilot starting a 40 size airplane and, the plastic spinner desintagrated and, a piece of plastic ended up in one eye. All I know is that he was rushed to the hospital. He did not belong to our club.

You absolutely must wear this any time anytime you even come within earshot of a glow engine. Don't even THINK of starting it!



Seriously, it's a freak accident. I once poked myself in the eye with a straw, should I wear safety goggles before drinking?

Actually its easier to burn one up with a weak battery because the engine stops on each compression stroke and the starter slips a little until it leaks off and spins to the next one. A strong battery just spins it, no stops on compression strokes.

Maybe YOU should.

Be seriously, there are plenty of accidents waiting to happen around engines. Safety glasses are a simple way to protect yourself.

It is funny, in the industrial world, you never see a guy who lost an eye NOT wearing safety glasses. Freak accident or not, it is very easy to lose an eye.

Try the 2 12volt batteries in parrallel.I thenk You will be surprised at the difference twice the cranking amps will make.

Dynatron and 6cell lipo...wow. DL55 started with one light touch on the propeller. I think it will spin everything under 100cc.
I borrowed it from my friend to start my .46 evolution and melted my spinner. Be careful with fluidlocks on small engines. I think Dynatron + 6S combo WILL break every shaft inside engine

If you want to be able to start any engine...... the answer is a Miller belt reduction starter kit. Use your dynatron and add the Miller unit to it and you will never have a problem starting anything!!!!! You can purchase from Miller or Mac Hodges .If you do a search you will find the phone #'s for each of them. There is no web site to order from.
Here are the #'s

Mac Hodges 866-924-9505

Miller 707-833-5905

Spend the $125 and never have a problem turning over an engine again !

True, I think that setup with 24 volts on the Dynatron would start a truck engine, full scale truck, not model.

I was going to use one to drive a piston pump at my summer camp.
