hey guys aint posted in here in a while, ive just recently picked up a ho-bao hyper one7 evo wiht a lamborghini bodyshell, was talking with a friend about it who then starts to spout alod about being an expert racer etc,
telling me that once the engines run in i need to replace the con rod and things like that
does that sound right?

im newish to nitro but never heard of that before

andy help would be great

hi mate, welcome back to the site. your mates talkin rubbish though, an engine once run in will last a good seasons racing without rebuild, much longer if your just bashing etc

Although......

There is a little truth in the statement.

The mechanicals behind it are...

When Braking an Engine in, it is going through some of the hardest conditions it will go through as an engine, because everything is sooo tight.

So, the Conrod has a Bush top and bottom, in the process of starting when everything is soo tight, these can actually be slightly worn.

Now... Only the Top Racers would usually do as your mate suggests. They may even replace the Front Bearing as this is where there is a potential Leak risk.

The Average Joe cannot and would not even realise both of these changes and as Matt has said...

No point really, treat the Engine Correctly and at about a Gallon/Gallon & Half you could think about a Front Bearing change. While your doing that you could do the Conrod then.

Hope this Helps a little further.

im at about that point with my hpi mt2, so replace the con rod, and the front and rear crank case bearings??
any help would be good

Without sounding condesending...

Are you Good enough/Capable of doing it yourself ?

Conrod's a pice of piss, but beaings are a different matter.

Remember... You Don't have to do it.

Is there actually anything wrong with it ?

Is it still running good ?

If you answered No & Yes. In that order, then Leave it alone.

There is a Very Good old saying...

If it Aint Broke, Don't Fix it.
