Wow, I put a lipo in my mini and its definitley quicker.
Seems to handle ok without any extra weight but I will bring some on saturday anyway.

I\ve never added weight to mine, and always run lipo. Not sure if it makes much difference. I do add wight to the touring car though, cos it was struggling for grip and the weight is off centre, but the mini it seems OK to me so never bothered.
The problem isn't the fact that Lipos go to 8.49v when fully charged, the problem is that when a cell drops below 3.0v... Then you see a lot of smoke..
So, if you're not using a regulator, you might blow up your pack one day...

a regulator or BEC controls the voltage going to your reciever and servo constant and regulated (prevents servo and reciever them from high current damage) it has nothing to do with the lipo pack dropping to 3.0v.
to prevent cells dropping below 3v you need a low voltage cutoff
anyhow your pack shouldnt blow if it drops below 3 volts per cell it will just become a brick
All but one of us are saying the same thing which is -
1) Too much voltage can damage your components
2) Most speed controllers provide a BEC or Battery Elimination Circuit which provides a 6 volt output for your receiver and servo. It gets its name because way back when, we all used to put 4 AA batteries in our cars to power these components, then as electronic speed controllers got better they introduced this circuit to eliminate the 4 AAs so - Battery Elimination Circuit or BEC was born.
3) Some speed controllers dont have this circuit and just pass the battery voltage directly through to the radio and servo. The Tamiya TEU101 which comes with many kits does this.
4) If a LIPO is used in a car with no BEC, there is a risk that too much voltage will reach your radio and servo and damage them.
5) Its unfortunate but true that this voltage is more likley to damage more expensive equipement which is designed and built to higher tolerances so while we all get away with using low end Futaba/Hitec servos, change to a high end model from the same manufacturer and its much more likely to get killed by unregulated LIPO voltage.
6) What this 'unregulated' business ? well a good BEC also acts as a regulator this is a circuit which trys to keep a constant voltage and current available to your radio and servo regardless of the damands of the motor.
7) This is the good news bit - You can buy a separate regulator so you can keep your existing electronics and know that you shouldn't damage them. A seperate regulator might even provide smoother power to your electronics and reduce any glitching you might have.
last but not least no radio gear or servo was ever harmed by too little voltage.
Lipo and Nimh batteries regularly die from too little voltage - to prevent this you can buy a LIPO cut off, or a lipo buzzer or solve all your problems and buy a speed controller with a lipo cut off and a BEC built in.
Its all been said before and its right apart from the one previous post which isnt.
