Best Engine Starter

My old engine starter, after 15 years of service, it has finally spun it's last spin. So I'm looking for a new one. What's the best engine starter out there for starting 150 size aircraft? I'll also be getting into 50cc gas at some point so is there one that will cover that range as well?

Best,

Gary A

Not sure I can answer your question with real expert advice, but the Sullivan Dynatron 12 volt starter is a very nice product for up to 30cc engines. They do make a bigger starter for bigger cc engines.--Smitty

The Starter Harold mentioned is a sweet starter but from 30cc on up is normally hand flipped.

This is my best starter.

Homemade, using lawnmower components and a motorcycle starter motor. The steel plate is from an electric wheelchair.

Pretty easy to do, when you set your mind to it. I doubt you'll own an engine which this thing can't start. Yes, it's a bit rough, but you can make a tidy one, if you want to. I paid a fiver for the electric motor. The rest is from scrap.




The Sullivan Dynatron is pretty good. Will start most things.

I had one for a few years, but it broke. The steel shaft has a couple of undercuts which house spring clips. These clips help to locate the armature between the bearings. Anyway, the shaft on my Dynatron fractured at the undercut. Totally beyond economical repair. Design fault, in my opinion.

Another for sullivan dynatron. Mine has started 40cc using a garden tractor battery. I start my dle30 with it regularly at 12v. You can run a dynatron on 24v, but I think 14v to 18v is ideal. For up to my G-62's, I use my milwaukee battery drill. I have an old riding mower engine I'm going to take the starter off of and use that to make something similar to Bogs.

I dont hand flip anymore. Got lazy a couple of years back and a G-62 backfired into my hand. Didnt break or cut anything, just too sore to type. Slowed down productivity at work for awhile. Now I use a big paint roller for a big chicken stick.

While I kind of like the lawn mower starter idea, I think I might go with the Sullivan Dynastart as a first go at it and eventually work my way up to the "larger and more robust" lawn mower model.

Many thanks to all those that took the time to reply.

Best,

I vote for the Sullivan too. I had other brands and they could not turn an engine even using a car size 12 Volt power source. The Sully will take up to 75 amps, so it will turn almost anything. Today I use a lawn mower battery and it over spins engines up to .90 without a problem.

I have an old antique sully I've been using with a garden tractor battery, thought it was too bulky and the batt was heavy so I got the Hanger 9 powerpro and the 12v powerpro power source with the 1.3ah gel cell and I would NOT recommend it to wind up a rubber band powered plane!! it struggles with my .91 4 stroke! I'm sure it's just the battery? the starter seems ok? but I feel like I really wasted my $$$ buying the combo with the power pack! someone told me the 12v 10cell was a stronger power source than the gel cell? but that's another 28$ on top of the 70 I just spent on this crap! DON"T BUY ONE! go with the sully! Like I said tho, the Hanger 9 starter seems ok??? I might put a 4s Lipo on it

I still use my original Sulivan I bought in 1975! It is VERY tired though and I recently started using it on 18 volts. It will get retired this year and will be replaced by an "import" though larger in design. I hve it bought but can't for the life of me remember the brand. It will also get the 18 volt treatment. I don't expect it to las as long as the sulivan though.

For 12V starters, use 4s A123 packs rater than lead based batterys.

These packs are so light that you could tape them to the starter, and they will last forever.

I bought a starter from a guy, i think from this group that made them from what looks like a motorcycle starter, i use a 5s Lipo pack. Its light as can be , and it popped over my buddies DA50cc like it was a 60 nitro. I try and find the post. think I paid little over $100.00. I have had alot of starters, nothing like this

The "Sullies" are VERY durable starters...

Dear Funcars & Julez:

The PIPE Here...that dear old, 1977 vintage Sullivan S600 "base model" starter of mine...



...which uses a "startpak" battery case of my own design from the early 1980s, equipped with switches to control power source, use/charge and even direction of rotation (switch with green handle just behind starter case) is going to get a fiberglass upgrade — read a fiberglass "exact replacement" made up when I can get back to work again — and a set of Julez' idea of a quartet of A123 cells right from "the source" to power it, thanks to Dave Thacker over here in the USA. It HAS used a Power-Sonic 12 volt, 2.9 amp-hour lead-acid battery before, but with the quartet of A123s, the "upgraded" one could be expected to be a fair bit lighter and powerful enough to spin over a 15 cm3 to 20 cm3 displacement four-stroke mill at full charge.

For a starter to be able to run nearly 40 YEARS later should speak volumes about its durability...and the "Sully" starters seem to be "the world standard" from my experience in the hobby.

(Hint: I DO have a replacement front plastic molding, to replace the chipped-up one in the photo...I just haven't INSTALLED it yet, that's all!)

Yours Sincerely,

The PIPE....!!

I thought I would replace this... with this... not even close!
The old sully has been cranking engines for almost 40 years and still puts the new ones to shame!
