Default Help tuning!! Duratrax's Overdrive ST

Hey guys so I bought a St overdrive back in the day, didn’t use it much as trying to tune it made me crazy after all the blisters and broken pull start cords! Anyhow I just found it and all my memories of wanted to smash it came flooding back Does anyone know the default setting for the 3 settings high, mid, and idol? Having a hard time to even get it to start let alone idol for 15sec! So far only 2 blisters today [:@]
Also is there a shelf life for fuel? Does it go bad? Any help would be greatly appreciated!

Well i dont know the stock setting for the needles but gas will last depending on the temp around it. Test it by smelling it, but don't do it like your a drug addict! If it makes your nose burn its good fuel

I would get some new fuel,get some 20%.Do you have the original velocity 17?I had mine out yesterday and it ran great.Heres my settings hs 2-3/4 out from flush,low even with collar,idle about a 1mm gap.These are my current settings and it runs great.The velocity 17 is a decient motor that holds a good tune when set up right.Good luck and post any other problems you have.

Hey just to let you know that the trx engines are always hard to start. so take a heat gun or hair drier and heat the motor up and it should be easy to start.

The Revo is defenetly the best rc from Traxxas,but if you would of looked around a bit you could of got something better.Make sure you don't run it lean while breaking it in or you will have a broken con rod.The 3.3 is notorious for con rod falure during break in so be carefull.A hair dryer to heat it up is also a good idea for the first few tanks.

Its amazing how things happen. One day you walk into a hobby store and next thing you POOF there is a new toy on the table and your sitting there scratching your head trying to figure it out and what to tell the old lady. I know I went through it with my Jato and the wife almost went balistic. I thought it was funny though.

Any ways on the 3.3 I personaly never had an issue with it. But then again I live in a warmer climate at sea level. But it turned out to be a good motor until the Jato was squashed by a car. I ended up getting the OS .21TM and it did make a huge differance in power and they drop right into the REVO. they are a bit pricey though. Wifey has no idea I got a new motor. That would be the end of the Jato. LOL.

I hear you on the poof heres another one,my problem is the bay.My closest hobby shop is a hobby town that carries my fuel but only sells Traxxas and I'm not into Traxxas.We have a great one about a hour and a half away that sells everything but the wife don't like me to go there much.If I go there I usually come out with something I really don't need but get anyway.Iv'e been hooked on the bay lately and have been getting some good stuff cheap but I promised I would take a break for awhile

Dreamland use the heat cycle method on your new Revo,look in the nitro engines forum and read the f/q sticky.Follow it to a tee and you will have a good strong motor that will last for a few gallons.

No, that's not typical of Revo's; they're very very durable trucks.

You just had a fluke; replace it with an OEM part and keep going.

BTW - If you're on your 6th tank and already bashing that hard, I would take it easy for a few more tanks first.
