If there is a website like that, I'm not aware of it. I sure hope there is one in the future.

Watts is a measure of the power put into a motor. Volts X Amps

Actual work being done is HP and Torque values.

Efficiency is how well the incoming power is utilized. Watts changed into work versus watts burned off as heat energy.

I like to keep an open mind. Not everything that will be discovered has been discovered.

There is alot to be said about Motor winding also. Then there is the scale of measure for the strength of a magnet. With limiting factors being saturation and demagnetization temperature.

I've done alot of research. I get lost around the point where it gets in depth about eddy currents in the Magnetic Harmonics. I do know this also effects efficiency. Clashes or opposing forces that spend energy fighting each other instead of doing work.

Your setup will be almost dead on as far as being centered. :yes:

I really like the look.

I thought I would update the progress I have made making my Revo more and more 'race worthy'... and where I have got it at now is nothing short of amazing, performance wise. Everyone at the track comments on how it doesn't 'look' like a Revo when racing, more like a truggy they say. I would have to agree, the weight distribution and center of gravity seems like it is just right for the chassis, and really seems to shine in the handling department, compared to a stock Revo 3.3.

The battery mounts are 1.5" CF angle from SierraComposites.com, the mounting brackets (alum.) are made from 1/2" x 1/8" 6061-T6 strips, a little small, but has held up fine so far after some pretty nasty crashes. The packs actually sit 1/4" lower than the E-revo battery compartments, and are a few mm above the bottom level of the servo guards.

The Rx pack mount is made from some CF I had laying around, which I cut, and glued with some CA glue, sticky Velcro all-around, including main power packs, which take the securing to the next level, really works well.

I was worried about the CF getting quite scratched and damaged from landings on rocks, and scrapping on stuff that commonly occurs at a track.

Enjoy.

Very Nice ZPB! :yes:

That Quark looks just like the original Quark that you first modded and posted about a few years ago. Is that the same one?

I see you're putting those Hyperion packs to good use.

Is that a receiver pack I see in front of the motor?

Nice progress! That's gonna be a mean one.

Thanks Sike, the G3 packs have 2 extra heat shrinks on them for good measure as the packs are low enough to get rocks and stuff hitting them. Yes, that is a Rx pack, the HP G3 LiFe packs in fact, they work great, I get roughly 50 mins per pack running a 7955TG servo. I used a friends of mine iPod touch with the 'dyno' app. (very cool), get this, the 0-60mph time on asphalt now is 2.1 seconds, down from a ~3.5 second before the mods. I find the tracking and understeer and oversteer conditions are so much improved... on hard pack driveway, it has a slight oversteer condition, which is PERFECT, you can also just chuck it into corners and expect it to come out with a nice drift, and perfectly controllable too!

Well, that is all I am doing to it this year, next year I am going to do a Eight-T 2.0 build with a special weapon, and it involves an outrunner motor, while maintaining CD, and slipper action.


Oh, and just for reference, the setup is as follows:

-Quark 125 w/6s G3 lipo, 1512/3D (1700kv)
-new E-revo shocks w/70wt f/r (silver springs front, blue springs rear) w/P3 rockers
-new 13mm axle carriers front
-RPM true track rear end
-E-revo diffs f/r
-front caster angle set as far back as possible
-the toe in rear is 1.5 toe-in obviously (true track)
-front toe is approx. 1.5 toe-out (this combo provides best straight line 'on-power' stability)
-weight distribution is pretty close to 50-50 front-rear, with a slight rear bias

Just thought I would post this as it is an insane winner of a setup at the track.

Rubbish.





















:lol:

It does look extremely well laid out, and the symetrical battery trays are really well done, perfect way to get that great weight balance.

Rubbish you wish. Is there supposed to be a picture in that gap? :neutral:

Wah? I thought that was the oldest gag in the (forum) book?

1. Someone does something cool.
2. You reply by insulting them > big gap > smiley & then actually compliment them.

Its called a joke! :smile:

Yeah, I think you're right... except it is just that old that I must have not picked up on it! :lol: I think I was just tired and couldn't think straight at the time. :wink:
