"too hot for nitro"

[nintendodude]

how do I know when it's at BDC? I usually just give the cord a tiny tug until it feels really easy and then assume the rest.... is this right?

I take the glow plug out and move the flywheel with my fingers till its at BDC..

You can mark the flywheel with a white marker so you know where to put it when its at BDC without taking out the glow plug..

i wldnt assume anything just in case.. you dont want the engine to cool while the piston is at the top of the sleeve ever.. it will stretch the sleeve eventually loosing pinch..

Stevo is doing it the proper way. But getting it in what feels to be the loosest spot is just fine too. The idea is to just get the piston out of the pinch before the engine cools. Which is about 30 seconds tops. Kill the engine, get 'er to the loose spot and your pinch will last longer.

funny how many people are out there who get by just fine without knowing these little tricks

Every time I get into a hobby, I tell myself "i'm going to stay the hell away from the forums and save myself a lot of money and frustration"

but what do you know, I end up on them anyway.

Oh well, I guess that's the curse of the internet

I appreciate the info guys... you would think that Traxxas would include this info if it does indeed help the longevity of the engine.

It's more important on higher-end engines. Traxxas tolerances don't compare to, say, picco or nova. Most newbie's will ruin an engine from tuning it wrong long before the pinch starts to go. Then they trade it in, hit the forums, and learn to do it right.

If I had the money to burn... I'd buy two of the same engine and treat one like crap and take care of the other.

Since I don't, I just play it safe. I use ARO when I should, don't run the temps above 270F, put the piston at BDC after every run, break the engines in properly... on average, I get 10 gallons through an engine before a re-pinch is needed.

If you think this forum is gonna waste your money, we can ignore ya. I would have tossed my nitros to the side a long time ago if these guys wouldn't have got me going in the right direction. RCNT= no bullshit.

All the forums are like this. I didn't realize how awful my kit lens for my XSi was until I read the forums.... 5 cameras later and about 5K in lenses, i'm still not happy - but i'm getting much better photos

I like learning, but I usually can't afford it.
