Eagle Tree Systems Car Data Recorder
I was looking for a review of some sort of this product before I bought it but, couldn't find one other than what's in the magazines and online, I wanted a review from a normal R/C racer type. Just in case I am not the only one who considered this product, here is my short take on it.
First off, I am a novice racer that is a "tech geek" so this is something that I just had to have. I use it mainly to verify my gearing is correct. This allows me to view the temperature of the motor throughout a 5 minute run. At the end of the run, I can see if the motor is too hot therefore overgeared, or vice versa. I can also see my steering and throttle inputs, RPM of my spur gear, a calculated MPH, and with the optional expansion unit, I can also measure battery pack voltage and amp drain.
I like the unit, it puts numbers in my head, I have hard facts (Temp, RPM, amp draw, etc) of what's going on with the car.
Combine the data from this unit with an Orion Lap Counting System... almost like I have onboard telemetry on my R/C cars. I have to admit, I'm such a tech geek!
So to sum up...
Is this a WANT or NEED? Want
Did this make me faster? Nope
Did it make me smarter? Yes
Now some pics:
THE DATA DECK
The data recorder is the black receiver looking piece strapped down to the upper deck of a Yokomo SD SSG. You can also see all the wiring the recorder comes with. The purple tronsponder is the Orion LCS. The way I use it is, during practice, I screw the top deck onto my Yokomo CGM. Before a race, I remove the deck (4 screws) and it's back to it's race trim:
The sensor in the middle of the picture is the current draw sensor:
Here is a pic of how I installed the RPM sensor, a magnet was CA'd onto the spur gear, the RPM sensor itself is held in place with zip ties and silicone on a bent battery bar.
Recently I have been experimenting with using this unit as a dyno. I remove the electronics from the motor, place the Voltage and Amp sensors to the motor, hook up my Turbo 35 to the motor (like a motor run), set it to 7V and run.
Here is a snapshot of the interface from this particular dyno run:

LOL Runin....
I bought it also... for the same reasons...
it's a heck of a lot of extra junk and weight on the car, but I've actually raced with it all on their a few times with good results although having weight up that high on the upper deck I'm sure does my car no favors in the handling department

I did a few races with mine on board but it kept yanking my servo wires out...
Fun toy, gets everyone gathered around your laptop at the track...

WOW!!! 
This thread is a YEAR old! I took down the pics awhile back but, I've uploaded them again.
I still have it but, it hasn't been installed on a car since these pictures were taken. I've sold my SD and am running a TRF415.
Anyone looking at buying the data recorder?
