Mine just stripped and I can't seem to find any places that sell the button alone...does anybody know a place where I can find one? Or different buttons that will work?

Get the Part Number, and type it, along with the brand name into Google.

I found a couple, but they're like 30 dollars...which is kinda ridiculous regarding I'm paying for a piece of metal.  Anyone know if other buttons will fit? like the one from force .28 or Axial .32  button?

Prolly not.  That's what it costs to replace things like that.  Or... you can buy a new engine...

That's an option, but my force .32 is actually very new still, Idon't even know how it stripped. I rather spend the $30 on the button than ~$200 on a new engine when this one is perfectly fine.

That was all I was trying to say.  Spend $30 to save $170.

In the future I'm gonna have to invest in a new engine anyway, there's barely any parts for this one around..

You actually have lots of options these days, including brushless.  With just one brushless conversion, you won't have to buy fuel, glow plugs, or any of the other ancillary nitro stuff on a regular basis.  You buy the setup once, maybe a new battery every year or two.  Then, when everyone else is tuning, adjusting, playing with clutches, etc... you throw your battery on charge, and chill out.  When it comes time to hit the track, you'll have the fastest car BY FAR and the least amount of head aches.   Just mentioning an option.

They carry parts for pretty much every ONFA engine. Very nice people too.</p>
