In the MRC D3 I put in a YS 91 paired with a Hitori pipe. The compression is to much for my 20 year old starter. It’s not turning over at all. I might have to beef up the battery or something. What kind of starter setups are everyone using start their 90’s? I think its time for me to bite the bullet and get some new field equipment.

HI Greg,

I use this one

Also the Daynatron Starters are very good on a 4S Lipo you can start every engine :-)

Best Regards

Hi Greg,

I'm using:

"Hi-Tork Starter. The original standard Sullivan starter for many years. Features a plastic drive cone, 2.50" diameter steel body and yellow end caps. 12 VDC operation, maximum 80 amps. 210 in-oz (148 N-cm) of stall torque. 5500 no load RPM. For all engines up to 0.60 cubic inches (10 cc) and many to 1.20 cubic inches. No. S600."

With LiPO 3S. But in case when it is a bit overload with feul (engine) even 6s. Sullivan starters are really strong and heavy workers. I've attached it with two straps directly to my starter. And in case of need just change the connectors.

I was looking at the Daynatrons. I had one a long time ago. I don't know where it went. I think im going to get to get another one. Thanks for the help.

24v Sullivan Dynatron Starter coupled with a 6s lipo... actually that combo might be too powerful... so I'll switch to 5s as soon as I can

(I'm checking everytime I'm about to use it whether or not the engine is flooded by turning the starter shaft manually)

If you're going to use lipos, run a big pack with a stout surge capacity. I have personal knowledge of the nasty fire that can occur if a pack gets a bit weak and then the starter overloads it. Remember that a Dynatron starter will easily pull well over 100 amps under heavy load or near a stall. Something to consider when you think about how most larger lipo powered electrics use at least a 2P configuration.

Good point Dr. Ben.
I think I might go with a Dynatron with the powerpack.

I use to use a 12V starter with a 12V lead acid battery and never had problem starting an OS 90 or YS 91. It's only when you accidentally flood the engine and stall the motor in trying to start that the motor get destroyed, so I always do manual turns/feel on the engine beforehand to prevent this.

I use Dynatron with 5S3200 strapped on with 2 velcro straps.
Heavy, but more than plenty of power. Even here in -5degC.

Greg,
The Sullivan power pack is overpriced once you add all the sub-c batts, just use two 6 or 7 cell car packs,

Of course, everytime we have to turnit few times manually. As a routine like checking if the throttle stick is down

Very true the price is high. I have to save my pennys anyway before I make the final choice.

Thanks Greg

SUL601 Sullivan Electric Starter, 12V Deluxe with 4S should be enough and has a good value to its price
Mostly I use it really with 3S, but always remember to fully mechanically close the throttle valve to its limit.

Greg, could you please put some photos of your D3? Detailed and overall

don't forget to 'get the shaft' !

All good ideas. Be sure that if you spend the dough on a good starter / lipo setup (I run a 4S 3800 packs with good results), you should spend the money on a good start shaft.

I recommend the Sullivan Deluxe start shaft. The hex ball works great, and the ball bearing supported shaft unscrews so you can store it in a flight bag or flight box.

Just something to think about.

OK I straped at 4s Kokam on an old Dyantron that I found in my basement. (I do have the Hirobo starter shaft with the one way). I have power like crazy now. It started right up. I had an old gel-cell before, It had nothing left to turn over the starter. It has since retired to fuel pump duty.

Even a brand new gel cell can be a PITA. The weenie little tabs on most small gel cells and the size of the battery itself make them in no way capable of delivering the amps demanded by a good starter cranking a 90.
