old ENGINE spark to life!!

[Finne]

I just dug out my old charger and batteries. It's a 7.2 1400mha kyosho from 1991.

figured it couldnät hurt that much to test them before i throw them away.

not realy expecting any results i charge them for 45 minutes (the charger is also from 1991 )

the old mechanical esc is broken, but I hotwired the engine to it just to see if anything happens.

Blue sparks appear as I connect the last wire, but the engine won't run.

So I guess there realy is life left in those batteries.

wow. they're 14 years old!!

Now I've put the engine in some corosives remover oil to see if i can bring that old baby back to life aswell.

I guess I wonät be throwing them away afterall hehe.

two days soaked in oil.

a few carefull turns of the engine.

Connecting the cables again.

"tick tick tick" goes the engine as it slowly ticktacks arond reeeealy slow.

hmm....

I try it once again.

WRRRRRRROOOOOOOM goes the 14 year old engine.

It's alive!!!

Now to make a homemade esc so I can use this thing without makeing sparks all the time.

Anyone have some usefull links or info on this? :unsure:
