Your temps are good as with the other efficient set ups we have on the forum. Now I saw that you mentioned 170, but how was your driving style when and if it got that hot? Have you thought about going higher on the spur tooth count? I see that you have the space for one.

i was driving like a bat out of he11 when i hit those high temps. i do have a 17t and 18t pinion that i plan to try tomorrow and see what happens.

How fast is your vehicle now? At that size, making it faster would be just too risky I think.

its 55mph currently. that is my estimate. i havent gps'd it yet but i know its in the 50mph range. i could definitely take off someones leg with it. who knows the formula for determining impact force. weight x speed ?? it weighs 27lb.

The plans that I have laid out for when I start my 5th scale vehicle shows a speed of only 40mph max for the onroad version. The problem with the 5th scale that I see are the plastic parts breaking at such speed. You could go with a bigger spur and 12T pinion to get a more efficient set up which will provide tons of torque and will be fun getting a few extra minutes of run time.

i actually wanted a larger spur gear but the next available size was 48t and just too big to mount. it could be done with a very large alum. shim under the center diff mount but i want to stick with the 40t spur cuz its simple and clean.

as far as durability the rampage has proven to be very durable. i have taken a couple of heinous spills and it didnt skip a beat. i have the Vertigo titanium turnbuckle kit since i heard the stock ones can bend .

i am just gonna play around with things and i am starting to feel not really concerned that i will see hot temps again. that day it got hot was when i was letting my 12yr old nephews drive it and they were making me nervous cuz their driving was not good. it was after they drove when temps were high. i had checked temps a few minutes previous to them when i was driving and temp on the motor was only 100*. so i am thinking that what happend is what aqwut said, that stopping and starting over and over and revving to top speed instantly builds up the most heat and i think thats what they were doing.

i am bidding on a baja currently for my next project. cant wait to convert the 5b. they look like a blast too. i want to build a nice 1/5 collection for myself.

I see and 100F is not even warm. Do you drive until the LVC kicks in?

I'm still waiting for a company that makes CF parts mainly for the military to let me know if they'll be able to do my parts. They told me they can make almost everything out of CF using their process and that got me interested.

Ryu-
Glad to see your truck is moving! (I was offline for a while.)

You said you were on grass when the temps were high Maybe all your runs were on grass, dunno, but I suspect the grass was the culprit. Any setup that is dialed on dirt or asphalt will usually run hot on grass. Even though it's a big powerful 5th scaler, grass is just rough on r/c stuff.


Kulang-
No offense here (just stating my opinion),but I hated the video. There were no "fluid video" shots. Just a slideshow. There is a bit of artistry when you add stills to video, in moderation. To me it seemed you tried to hard to make it a good video with all the stills, and should have left some of the meat and potatoes. Just my opinion. Either way I was happy to see the big guy in action, I just prefer real time video......
