Transmitter Mod for Range
I have no pictures right now because both my cameras are in the car and the
wife has the car... lol
I got really lucky that the Walmart in my area had a "Close-out" on these and I got
one for only $25 and a few days later, I got 2 more for $12 each
I noticed a question about "Range" in this thread and thought I would take one
of the transmitters apart to see what kind of antenna it might have.
It has a small "Wire" antenna that due to being enclosed in plastic, more or less
2 times, it is my guess that this is the reason for poor range.
Disclaimer: I am an experienced Computer Repair Tech and am very familiar
with some electronics modification and adept at soldering.
If you are not comfortable with modifying such items and are not confident in
your ability to expose the mechanics of such items, and are not comfortable
with soldering in close areas... DO NOT TRY THIS MODIFICATION!
I will not be responsible for any subsequent damage that may arise from any
attempts at this/these modification(s).
Here is what I did in attempt to extend the range to full potential:
I have never had much trouble with range - out of the box, I was able to go about
60' to 80' Up and about 60' to 80' out ... I would estimate about 120' max.
OOB, I can fly it well up over the buildings I live near and the trees nearby are well over
Since the Mod, I have noticed a slight difference in range and I don't lose connection
with the plane.
Good "Rule of Thumb:
1) Keep the front of the transmitter aimed at the plane and you shouldn't have
any loss of signal.
2) If there are other items in the area operating on 2.4GHz wave-lengths and
the same channel your plane is on, this will affect the signal between your plane
3) Many Cordless Telephones operate on 2.4GHz to 3.5GHz... this could be a
potential for signal loss.
Antennas arranged close to a receiver will also get mixed signal from the
other electronics in the receiver... Therefore, extending beyond the actual
receiver will permit better signals being sent and received.
I found this out when flying my son's Syma Apache.
If the 4' antenna wire was wrapped around and extended to the end of the tail, it
would lose signal about 30' out, due to the LED strip in the tail acting as a
But, if it was wrapped around a Landing Gear Leg or left to hang free, it wouldn't
lose signal until about 80' out.

A Leap Beyond... Real External Antenna Mod
In my previous post above, I gave instructions on how to do a simple mod to the
transmitter by making a hole and exposing the antenna wire. This reply will show
a leap beyond that to a real, detachable, External Antenna.
For those of you who are more Mechanically inclined, I have just posted a video
on Youtube of an External Antenna Mod I created for the Air Hogs Hawk Eye Blue
The video is about 6 minutes long and shows the plane in flight well over the
maximum range as listed on the box.
This was possible due to the addition of an External 8" Antenna made from computer
parts (e.g., Pin Coupler tips, Motherboard Stand-off bolts) and an 8" piece of
plated copper rod (which is out of the thinnest tip part of an old antenna).
The transmitter case required minor internal modification but it is simple...
The tube in which the original antenna wire is placed needs to be removed to
allow the Stand-off bolts, washer, and wiring to fit - and the washer needed
trimmed on 3 sides.
This mod took me about 3 hours to create and build.
Text Narrated and 4 photos of the project and finished antenna are included in
Also note that there is minimal "Porpoising" - This one has always flown good
right out of the box but I have noticed that "Porpoising" comes mainly from fighting
wind and when having the plane at full throttle during climbing.
There is no modification to the tail stabilizer and no weight has been added in
the nose area for steady flight.

Just picked one of these up. The prop slot design looks like it will be causing a lot of drag. Has anyone sanded the leading and trailing edges of the slot to try to reduce drag?

I just bought one of these for $27 at my local walmart. The storm hit New England that afternoon, so not much flight time. Although I had little issue flying it during the falling snow! Now that I am house bound I was wondering if anyone had any other hacks/mods for these things.
I would like to fool with this thing a bit more -one of the things I'm interested in is that, it shows up as a 64meg flash drive under "charge mode" -and as a USB device with all 0000's under "on mode"; the most data this gives me is "\VID_0000&PID_0000\6&150ea90&0&1". So this makes me wonder if this toy could be runing a linux variant. If that is true, then there could be some video options available to us...
That notwithstanding, I was thinking of tearing this plane down and sticking the electronics onto one of my rtf heli's for some indoor filming. And that brought me to asking what kind of cameras are ya'll using for your planes and heli's?

My hawk eye looks different after tonight
One flight to test it tomorrow, unsupported foam board, likely to crack on landing. If it looks promising I will redo in depron with tape reinforcing, maybe some fine cf. Don't know yet. If anyone is interested in the plan I have pdf's that I threw together.
The camera is now rear facing.

I just found this plane here in Sweden, at about 40$, they used to be about 120...
Thanks to this thread i guess i will pick one up tomorrow, sad about the range issues though, I´m used to Silverlits and have 15 or so, but none with a camera.
Nice to see that people are still enjoying these small wonder-toys!
10$... what a dream price!

Waiting to see your depron version, and as always pics and movies are nice!

Quite happy with it, but as always, too short flight times, wish the batteries were exchangeble, an easy mod, I guess?
