Hi,

I'm using hobbico electric starter: http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXL396

and power core setup: http://www3.towerhobbies.com/cgi-bin...&I=LXL372&P=ML

with this totally new battery: http://www3.towerhobbies.com/cgi-bin...?&I=LXL373&P=V

It doesn't spin my OS 75AX only when I'm spinning the starter first and than hitting the spinner only then it turns and starts the engine.

1. is it the starter showing its end?

2. is this battery gonna power a stronger heavy duty starter like this one: http://www3.towerhobbies.com/cgi-bin...?&I=LXJC37&P=7

I'm thinking about getting that heavy duty starter with a small car/motorcycle battery but it has its draw backs like keeping an acid container in the car...


Thanks
Alex

I had that same starter for a long time when I first started flying. When I bought my first 4 stroke (magnum 91) it would barely turn it over. It definately would not turn my saito 100's. I bought the 1.80 hobbico starter and with the same original battery it will fire all my engines including my 26cc gasser.

I had one of those hobbico starters too, they are only fit for up maybe a 60 size 2c motor. It struggled with my YS61. I used a sealed type aircraft battery. I then got one of the sullivan HD starters and its good for uo my YS140s motors. Its not a dynatron, its the one before that. I found the hobico just wasnt worth the money despite the blurb it came with said up to 1.20 size motors. i asked the gut in the LHS if that was with the glow plug in or out? Over the years I have found that it doesnt pay to buy the cheaper equipment for your field box, the cheap stuff doesnt last nor cut it when it comes to servicabilty

I would recommend a sullivan dynatron. It will be the last starter you buy. Expensive, but I can start up to 40cc gassers with it using a 12v garden tractor battery. I used it for many years with a gell cell 12v 7amp battery for up to .90 2-strokes. I've seen them used with a battery attached to it for easy portability. I never did that because I wanted sure fire starting power everytime. It can be upgraded with a Miller gear reduction to turn bigger engines. They are d@mn near bullit proof if you know how to take care of it (dont stay on the starter button for long periods of time when an engine wont start). Mines about 9 years old and uses the garden tractor battery in a 6-pack cooler for carrying. The ones listed are ok, but dont have the balls the dynatron does. I hate to sound like a comercial, but if you're in this hobby for the long run, this is the starter to own.

Thanks guys I was suspecting that after 3 years of extensive use something gonna give up, it just surprises me its an electrical engine there is no friction or touching parts there..
Now I understand why people use the expensive starters...

in electric motors, as in fuelers, there are motors and then there are motors. Its all in the windings, how many and how heavy the wire, and even the quality of the whole assembly, it all comes into play. again, you gets what you pays for. I'll pay for quality any day. In the long run it always works out cheaper and better

yes it sounds familiar....
The hobbico is the first starter I bought to start 46 engines now that I have 90 size it was working for a while and than I started to use chicken stick or just flip the spinner.
I guess everything is working until it stops working.

Hi!
Nothing wrong with the starter...the problem is that battery!
If you are going to use a 12V Pb battery use at least a 10-12A motorcycle battery...1,3A is not going to cope with larger engines!
