Quark 125 & Lehner 1950/8

Leroy, 5S of those cells, especially in 2P, feel like 20 Nickel cells to me. Keep in mind Ni cells drop voltage under load. And with almost 150amp as a continuos rating on Danverz' setup, he won't have to worry about voltage drop.

Sure Dafni you are right, but there is a bad face of the coin, the weight.
The truck is about 5.2 5.3 Kg . Not really light.

I just posted some other photos in my album.

I added the antenna support, the servosaver, some blu alloy screw caps
(I love them, they make everything cooler) and the 2 motor heat sink with
fun.
I have to say 3racing 3x3 fans sucks a lot :) Really more and more better the
muchmore ones (we are talking abut 5/6 volts fans).
I cannot wait for the roll cage, it's on the way :)

Ciao !

I think you got the wrong question out this. It was for standard_63.

I would probably guess close to a 18 cells with out the voltage droping.
20 cells at 1 v is 20 volts and it takes some serious draw for that. I caught the 5s 2p configuration. The 5s 2p is probably just as light as 20 nimhs but more run time for sure.

Ops :)

With my setup and on the road with the road rage tires I saw a peak of 97
Ampere and a peak of 1880 watts. And I'm running 2WD.
I think with the second differential and the with the grip of the front tires,
on the road, I can achieve 120 130 Ampere. It seems to me to be reasonably.

And sure, it's a huge draw :)

I'm running a 4s lipo -- 2x 2s1p 5000mah PolyRC packs.

My run did consist of a backyard track session with some wheelies and roostertails, then immediately out to the street for 10 or so full speed passes, and then back to the yard for more jumping and roostering. After 18 minutes of that on my 12lb. truck with heavy tires, I'm not sure 180f is so out of line for the 7xl? I need to try a fan on it next.

A 8XL would certainly fix part of your problem. Thats alot for the 7XL. A 8XL will have more torque and handle the heavy truck better.

Hi guys,
this morning I broken tooooo many items in a tooooo high jump with a toooo
bad "landing".
My Maxx hit the groud with the front skid plates, and it curved it, broking the
servo carbon fiber servo plate of the gorilla chassis.
I think, do I make it again by myself with a bigger carbon fiber, or do I
buy the alloy one ? I don't know yet.

BTW my dpr-100 is not able to record more than about 24 minutes, using
a resolution of 10 records per second and 2 temp monitor.
Here's a graph of my first 24 minutes of bashing.
As you can see I surely will achieve the hour. And I am very very happy
with the temperatures. Red one is the ESC and yellow one is the motor.

Ciao,
Daniele

This is a bit off the topic, but how do you get the graph? I'm thinking you have something wired in to collect the data? what is it? thanks, sorry for the hijac!

[coolhandcountry]

Eagle tree will record the data for you.

[neweuser]

Hey Leroy, where do you get the set up though? You must have to connect it to the system some how...

[squeeforever]

Go to eagletreesystems.com and check out the Micro Power E-Logger. Just plug a Deans into, and the battery into it, and it records all the stuff you have sensors for. Metalman has one and loves it. They also have a LCD panel for it now so you don't have to use a comp.
