Very nice...just make sure those battery wires can't touch the spur...ah, the joys of Zip Ties...

Nice job Hippie! :004: I love the clean wiring. Is it possible to slide in the battery tray on the motor side inward since the rear brace is opposite the drive bone? This would help out the left to right balance.:032:

Thank's Cadima

Not really there is about 1/8 or 3/32 of a inch or less as it is. I acctually slide the battery's out to were the chassis kicks up on both sides to make sure they both clear the diff .

It"s Alive
 

I got my ERT running tonight. Im running a 62/13 gearing right with a 9XL with 9920 no fan & 8000 4s lipo. I was playing around out front of my apartment for about 6 - 10 min it's 11.30 pm EST. My temps were

ESC 125
MOTOR at can 125 at heat sink 100
Left lipo 92 & right LIPO 92

So far im very satisfied. Any suggestions ?.

Also can i just throw them back in my car tommorow & have fun or do i have to charge them again & do i have to discharge them or can i just store them ?. I dont know how accurete my OFNA temp gauge is.

I ran it again today here are the results after about 8- 10 min of high speed runs. .


ESC & fan 105
Motor 155 at can
lipo 103 each

Those temps are good- cold as a cucumber.

1st day at the track results
 

I finally got to the track with my ERT today. I was very pleased with the results. The track was blue groove & a light coating of dust, air temp was close to 90 degrees

My equipement was
9XL with 62/13 gearing with fan
4s 8000 maxamp lipo's
warrior 9920



The following results were after at least a 15 minute run

Motor temp 155 average max was 170
lipo temp were 108 average 118 max
ESC was 105 thru the fan average, 121 at the heat sink max

Mac what are you running for oils in your ERT ?

FR shocks
RR shocks
FR diff
CEN diff
RR diff

Sounds like you have a good setup there! Nice temps considering the ambient temp...

I thought so to . I could use a touch more speed on the front streach. I wonder if it's better to go to a 14t pinion or go to a 8XL motor ?.

It very much depends on the track conditions but I like it a bit stiff. Most of the tracks I run on are not very bumpy (at least not at the start of the day) the trend up here is big, flat base with nice size jumps, not bumps...so I run 50 or even 60 wt oil in the front and rear. I tend to run the same on both ends. I feel like the Electric truck has plenty of squat already so on mine, I don't drop the rear 10wt like you do on most trucks. As for Diff oils, it's 7K or 5K up front and 3K or 1K in the rear. In the center I mix it up often. I keep a 50K built and a 30K built. I like the feel of the higher oils in the center but I have swapped it down to as low as 10K. I like the 30K best though at the Wolcott race I ran 50 for instant acceleration over the triple.

I'd always say give it a shot and see, remember that one these trucks 1 tooth is a MASSIVE gearing change so I'd never move more than 1 tooth up or down if you feel like you are in the right ballpark. Personally I run either a 9 or 10 tooth, never tried anything bigger with my current setup.

Thank's david

So you run 30 or 50 thousand in center, mine has 7000 in it i belive, from the guy who built it. I'll go up to at least 20,000 to start. My home track is very smooth ( well groomed) & a real blue groove track.

It's very close in my opinion. I'll try a 14t pinion plus try different diff oil might be exactly what i need.

Oddly I like the way 10K feels in my Nitro CRT but I didn't like it at all on the electric. It diffs out WAY too much and then it accelerates erratically. With a light diff oil in the center I'd say mine feels "mushy" it takes extra time to get traction and start moving out. It IS easier to drive but it's slower...I like the feel of a heavy center...20K is great (if you can find it...I seem to recall it was hard to come by) anyway give it a whirl and post up your findings.

DM

David use this program & make your own. Use 10 & 30 to make your 20 .
This program tells you how much of each oil weight to use to make your desired weight.
