"I've been using the eLogger and the sensors and Power Panel
display for a couple months now. . . GREAT PRODUCT!! It has already
paid for itself two times over detecting over-amp situations I
wouldn't have known about until the battery smoked."
Keith, Tennessee
"The eLogger is awesome!!! It blew my mind on the amount of data that you can retrieve. I liked how I could see my actual flight time, the amps and battery current and the mAh. It will definitely help in the long run with problem with the plane. I can’t wait to add more features like finding out my RPMs."
Joel, California
"Just wanted to say thanks for a great product. I installed the eLogger
and the PowerPanel on my Trex 600e and love it. I won't fly without it.
Being able to glance at the display and see how much battery power is
remaining, and the temp of the battery has saved me hundreds in
puffed packs."
Charles, NV
"Thanks for your amazing Glide version. I just received it, and only have 1.5 hours of flight time on it, but it was truly amazing.
I would call myself an intermediate glider pilot. I am able to catch thermals here and there. I normally check out known locations at my flying field to see if there is lift, or depend on hawks, or other gliders to help spot lift. With the Glide, I caught 3 major thermals, and had many, many more indications of lift areas.
I would not have located many of these without the Glide. It makes it pretty easy to find the center of a thermal, and I was even able to follow a thermal that was getting blown down field, something I have never done effectively."

Now I can state without doubt
that your company offers the best equipment in this field, at
the lowest prices, and your support is among the best of any
business I have interacted with. Thanks so much for your superior
products and service. I look forward to doing further business
with you.” Vrezh Yetanikyan, AVVAT Inc.
“Any way you look at it, the CDR is something that I have
been hoping for. If you are an information junkie like me, you’ll
be ordering yours today.” (product rating: 10 out of 10) Derek Buono, Xtreme RC Cars
“It seems to me every serious modeler
would want to get a Flight Data Recorder to monitor his, and
his airplane’s, performance.” Jim Oddino, RC Modeler
“The potential ramifications of using the FDR are so
vast that that it is difficult to imagine all the ways it
might affect our hobby…” Tom Rockwell, QuietFlyer
“The Eagle Tree Systems - Flight Data Recorder is truly
an amazing piece of equipment. To think that something this
sophisticated can be installed in one of our miniature aircraft
is nothing short of a minor miracle.”
Mike Buzzeo, RCUniverse.com http://rcuniverse.com/magazine/article_display.cfm?article_id=253
" I don't know if it was beginners luck, the smooth air,
or data processing techniques I used, but all the data points
fell right on a curve that describes a classic glide performance
polar diagram. In my opinion, these are phenomenally consistent
results, better than I expected to achieve. Based on this,
I think your Flight Data Recorder is a significant advancement
and will be a truly useful tool for those who are interested
in measuring steady-state model performance." John Watkins, customer
“Eagle Tree Systems’ Flight Data
Recorder is an amazing device…The guys in the club will
eat this one alive.” Jeff Troy, Hobby Merchandiser, October 2003
"....I crashed my SuperStinker with the logger on board
– really neat. ..... From what looked like a safe altitude
and sufficient speed the bipe unexpectedly stalled (from knife
edge onto it’s back), and entered into a death spiral.
After analyzing the data it seems pretty clear, that
a) I was only about 160 feet high – too
low to recover from that problem
b) Airspeed had fallen below 35 mph – I had previously
measured the stall speed to be around 40 mph – It seems
I caught a blast of tailwind
c) When I was trying to rescue the whole situation the power
drain of the servos drove voltage below 4.3 Volts.
Three reasons, each of them significantly contributing to
the disaster… For sure, the main reason was my mistake
to begin with, but without the data logger I would never have
understood WHY?!" Matias Rajkay, customer
"The interesting part of all this is I was testing the
Flight Data recorder, from Eagle systems and I have a complete
replay of the flight & crash. The damage sustained was
from a 1 point spinner landing at 54 mph.
I learned three lessons:
1. Don't let your instructor think you know what you are doing,
cause you don't.
2. Wing bolts are better than rubber bands.
3. The Flight Data Recorder is really a neat tool. "
