quark placement/neu/ direction?

first things first, you people are awesome, i've had very little headaches while building my g2r e-revo (also my first build). Although, it has taken some time to complete, it is still a fun build. With all the great and speedy advice, i have become hooked on this hobby. so I can't thank yall enough.

ok now back to my nearly finished build. I'm soldering up the trakpower 4900;s and the neu/quark combo. i need to decide the direction of my tranny, motor, and diffs. i will be racing mostly, so track performance is key.

1. solder connectors on quark/neu. yay or nay? if so male on which?

2. which tranny/motor direction has best weight distribution? cog?

1. The best way to make the connections between the motor and esc is to hard wire them. Solder them together without connectors. Most do, however, use connectors because it makes maintenance and other things easier to deal with. I've had good luck using the 5.5mm connectors. They have a good bit of contact surface area and have worked well for me. Put the female ends on the esc. That way, if anything does come loose, at least is won't short out.

2. I think that the motor to the rear configuration works the best, but it depends on the way that you set up your suspension and the way that you drive.

thanks Aangel !!
so hardwiring is the best. makes sense.
i think i'll go with the 5.5's just to be more versatile and maybe easier to mount. i'm going to use the rcm quark heatsink mount. do you recomend i use fans and why is the heatsink so much bigger than the esc. and about mounting the heatsink/esc sideways ? anybody got any pics? maybe a template of a mounting plate?

From my personal point of view, fans are great to use when you don't have enough heatsinking. I don't like to use fans and only use them when I have no other choice.

I think that the best way to mount the Quark is to the chassis. That's about the biggest heatsink that you will have available on an rc car/truck.

I have a bit of an odd Quark setup. I added an additional six capacitors to my Quark. The capacitors are contained in an aluminum box which is roughly the same size as the Quark. I epoxied both the capacitor bank and the Quark to a 1/4" thick piece of aluminum and then mounted that to an aluminum plate. The aluminum plate is attached to two aluminum standoffs which attach to the chassis using two of the stock engine mount holes.

This setup added a bit of mass to the Quark case and effectively transfers heat to the chassis. I don't run any fans on my setup and don't have any thermal issues.

my chassis is carbon fiber, will this dissapate the heat effectivley?
i don't have the stock motor mount, so i guess i'll custom do sumpin. well pretty much all the stuff is "point click buy" so i need to put my flare on it
i'd like to know more about adding cappacitors, good ideas
no fans is cool with you then hopefully cool with me
thanks again

I am sorry to disagree with you AAngel. But I was told and read on the web that If you put male ends on the batteries it's like having bare wires. If you have batteries lying around with bare wires, It's not "if" they will be shorted out it's "when". So IMHO I would put the males on the ESC. But all that stuff you are doing to your Quark sound great. Would you post some pic's because I don't understand exactly what your doing to add the extra capacitors. I just got a Quark and one of Mike's heatsink's, But I would like to add some capacitors for even more protection on my investment. (Big smiley) lol. I wish they would fix the smilies. (frown) lol.

he was talking about the motor connectors, not the battery connectors

this is how i have my quark mounted and it works great, and stays nice and cool, also on the backside of the heatsink is (2) 40mm 5vdc fans.....Also the heatsink was drilled at tapped on the side of it and mounted to the rear ext plate as well as thermal paste was used too.....

Sorry AAngel, I was thinking about the other end of the esc. Thanks for the heads up bdebde.
