Agreed....

What castle link settings are you guys running in your 1/8th buggies. Is there anything in your testing you found works good? I have a VE8 and I havent had a chance to run it but I have it set to 60% brake, 30% drag brake, 40% punch control. I left the throttle curve stock and I have it set to sensored mode.
Is there anything I could tweak for better performance. Is there a database with peoples settings online anywhere?

Run it in Smart Sense, most efficient. I wouldn't bother with drag brake or punch control. The punch control is your finger.

A BEC really just separates your esc/motor from your electronics to prevent brown-outs (heavy amp draw conditions).

The BEC circuit manages your electronic voltage (rx, servos, transponder) while the ESC manages your motor's voltage. Your external BEC usually runs at a much lower voltage than your esc/motor.

Typically this is done with bec circuits that are built into most ESC's, so people don't quite understand what a BEC really does. It just splits a single source (battery) into two different, dedicated circuits.

*I'm still not positive why its called a Battery Elimination Circuit but whatever

trying to help out a friend. He picked up a used slash 4x4 roller. He wants a really good solid setup and wants to run 2s, and he already owns a mm pro. Its a open class, so whats a good motor and gearing starting point. He is a racer and will not be bashing at all.

Because it eliminates the need for a separate receiver "battery" pack.

Yeah, back in the day we used to run AA's for the servos and receiver and the main batter powered the motor. Then the BEC ran everything off one battery. Now with the high current draw of our electronics, some BEC's just can't cut it so a separate BEC are necessary to keep from glitching or browning out.

I am thinking about picking up an cc 1800kv buggy motor and I plan on running it on 4s. I know some of you guys are running this setup but is seems that the total motor speed of 26,640rpm is a bit low, anything to be concerned about? I thought we wanted to shoot for the 30,000 to 35,000rpm range. if i gear my Ve8 to 22/50 i will have the speed i need but will i lose efficiency? any other draw backs to this set up?

Default MMP/Novak Ballistic 17.5/HPI Blitz

Is anyone using a similar setup in their HPI Blitz? I'm just shooting in the dark when it comes to the MMP setting for this combo. On a medium size track, I'm running 28/77 gearing. Where should I be at with the cheat mode settings and motor timing advance? Any suggestions would be much appreciated!

Exactly right...but we won't get into the history of rc devices I didn't want to confuse people.

Redbarton - have you posted this question in the HPI Blitz thread? You're more likely to get a model-specific answer there.

Ill tell you the drag brake is what makes me go fast. As soon as I let off the gas the front end trail brakes and makes the tires hook up in the corners. I am not loosing much corner speed and the advantage of being in control is worth it IMO.
I will change it to smart sense though.

Thanks

I agree with you concernig drag brakes. Many electric racers run drag brake to load the front end when entering a corner, its much faster than trying to brake and get back on the throttle.

I ran my ve8 on 4s with a tekin 2050 on a small high bite track in 100 degree heat this last weekend and it was perfect. Another guy was running a tekin rx8 and he thermalled several times. He couldn't believe that I was running a 1/10 scale speed control!

Man, that setup is pulling some serious amps too! Have you tested without a fan yet? I'm just curious to see how the MMP holds up if a fan goes bad in the middle of a heat.
