Starter for gas engine
I have a strong battery operated starter that I use for glow. It works fine with my DLE-30, but someone told me it spins my engine too fast. Is that valid concern?

No. It's always funny to me the theories that people come up with. What method does he use to match the speed of his starter to the optimum starting rpm for his engines?

RE: Starter for gas engine
I like for my starter to spin at 2400 rpm. That is more or less idle rpm. I've started a lot of different model engines with it.
Twice that is OK too but getting up to 5500 or so is just too fast for me. I don't like the Sullivan Hi Torks for that reason.
A friend has one that is 11,000 free running but he always keeps it against a prop spinner. I don't like that,

RE: Starter for gas engine
Once the engine is choked and ready to fire, a bump with the starter is all it needs. The ignition will fire on the first rev and the engine should start immediately if there's fuel in the head. If not, re-choke and make it ready. There should never be any reason to spool the engine up to the starter's max speed as was true occasionally with glow

What is NOT FUNNY is a bent connecting rod. A real flooded engine and too fast/strong of a starter can bend a rod. With cyl strait down...flooding can happen....so can bent rods happen.

RE: Starter for gas engine
I'm not sure but I think I bent the end of my crank on my DLE20 using a starter. Inever crashed or nosed over but I noticed that the spinner was rotating off center one day when I was rotating by hand. I changed the crank and it was fine again. I only use the starter now if I have to. Hand flipping is easy and if it won't start that way there is most likely something else wrong. Just my opine.

You guys laughing at the first post saying about spinning too fast and he is right and you are all wrong so he should be laughing. It is too fast for a gas engine, that is why they make gear reductions to slow down the speed.

Thanks, I wondered if top rpm is around 8000 rpm then my starter should be fine.

what starter/battery combo will spin a gas/nitro engine at 8000 rpm?
I have a hobbico 180 with a 4s lipo on it and it will spin my 30cc syssa, maybe 500 rpm, when/if it starts its spinning faster than my starter spun it.

RE: Starter for gas engine
Hey guys. good comments. got one for u. My hangar nine starter wore out (bad brushes). I cut the shaft off of it and put it in my craftsman 19.2 volt cordless drill. I put it on low and use it to start my dle 30 just fine. I use it on my da 50 some. but it will just barely start the 50. if u have a wore out starter give it a try.

RE: Starter for gas engine
The reason why they make reduction gears for these starters is to get more torque out of them.
I have not seen a starter spinning an engine with excessive rpm....and when it's flooded, it won't turn over. The rubber insert will just slip.
When I got my first gassers I had a hard time getting them started.
The starters I could buy where expensive and most of them required a 24 Volt power source.
So I just build my own, used a motorcycle starter and made a reduction gear. Works perfect.
And I rather break an engine then my hands.
I cringe when I see someone starting their engine with their bare hands. The accident is waiting to happen.

i start all my gas engines by hand never had any problems once it is wet the electronic ignition makes it easy to start

Recently Ibought a Pacific Aeromodel 3:1 starter. Two 7.2v, 1800 mAh packs are strapped to the frame. It's a torquie little sucker and isn't much heavier with the batteries than the is Sullivan without. It starts my 43cc engine nicely.

RE: Starter for gas engine
I too am a newbi to gas engines and I was recently advised that a gas engine will start by hand with the throttle set at idle. I tried and indeed it does. I was also told that reving the engine with the plane only restrained by the tail was dangerous as the more powerful gas engines were capable of pulling the tail right off the plane. Another nearby modeler confirmed that this had indeed happened to him only a couple of weeks earlier and he had only been saved from injury by the push rods holding the plane back. The engine I have by the way is a DLE30.

RE: Starter for gas engine
For years and years I started every engine glow and gas by flipping by hand. Whether its glow or gas, if the fuel is there and the heat or spark is there, its gonna run or at least pop. My gas planes are all 50cc and up. First start of the day is perhaps 6 flips with choke on, then 1 or 2 with choke off. One flip the rest of the day. BUT, I dont do that anymore.....one engine had a flaky ignition and was getting hard to start and would not idle. Well it popped back in the middle of a flip and just about cut my middle finger off. Since then I have used a belt reduction on a Sullivan Dynatron at 24V for gassers. Spins about 2100 rpm. But as was mentioned earlier in this thread, if all else is correct, the the engine only needs a bump from the starter.

RE: Starter for gas engine
I use a 4-stroke gas engines and, while docile most of the time, they can bite back. I've never given a thought to the speed of the starter and whether it might harm the engine. I was quite happy in my ignorance. I'll continue to use the starter except for those few occasions I stall when taxiing or after landing and don't want to carry the plane back
