Motors and gearboxes - verses Brushless
outrunners
Indoor flying is a
balance between the power of the motor for the weight it adds to the overall
model weight, and duration times. As the biggest single weight is the motor /
battery combination, it stands to reason that the lightest and most efficient
set-up will have your model flying at its best.
Brushless motors and LiPo battery packs offer
this efficiency, but at a greater cost than brushed motors and NiCad or MiMh.
You can of course swap over to one of these technologies without going all the
way and buy both.
Below, are a few items we have found, and
mostly tested ourselves...... and offer these findings up for your enjoyment.
The
DP 3A is a tiny (around 1gram) brushless speed controller built only for
single cell applications and for current draw up to a maximum of 4A
bursts.
This brushless esc is only to be used for Lipoly single cell
applications where no more than 3A constant is needed.
Features.
High speed MCU. Fast resolution for snappy throttle response and
excellent low speed timing.
Cell Protection, signal lost failsafe.
Smooth startup.
Linear Throttle
Supports 240,000RPM (2 poles) / 40,000RPM(12 poles)
Plush
10A Brushless Speed Controller
The Plush series of ESC are a very good quality controller with a
broad range of programming features and smooth throttle response
compared to other BESCs in the same price range.
These escs have linear throttle curve and can handle 10A continuously.
User Programmable, both via controller and optional programming card.
The programming card is an excellent item as it instantly tells the user
the current settings and with a few simple clicks of the buttons, the
user can change the settings and have graphical reassurance of those
changes.

with a GWS4530 prop on a 300mah 2S
LiPo the performance was:
9700 rpm, 1.7 amps, 7 volts. The calculated thrust is 66 grams.

Nice little motor
bought two, both weight 5.3 grams. Motor mount brings weight up to 6.6
grams.
Output wires are glued to bearing tube and are fragile, but then so is
any plane that flies on a 5 gram motor.
Needs 2 mm prop mount.
Roy Oetting
Nice looking motor. The shaft is 1.5 mm. Tested on 2 cells with a
GWS 4x2.5 - 1.24 amps, 9.1 Watts, Thrust 53 gm force, 11.4 K RPM. It
should be a nice motor for a 2.5 oz plane.

I got my motor the other day and was getting ready to run it and
noticed that a few of the windings had popped out. I put them back in
place and brushed a light coat of clear coat on them to hold them into
place. I would recommend doing this even if your motor doesn't have
this problem. One thing is for sure I will because I'm sure rewinding
one of these would be a pain. Still 5 stars great little motor for the
price.
Nitrocharged
After reading other reviews here I did a series of checks. First, I
checked on the windings. I removed the c-clip retainer from the shaft,
pulled off the bell assembly and inspected the stator. It did have a
few winds that were a little close to the outer limit of the stator
but a quick push with my fingernail in between all stator gaps got the
windings all snug again. None were hanging out. I just like them snug.
The wiring is indeed fragile. Use heat shrink on the terminal end
around all the leads to give added strength. I broke one lead at the
solder joint just from handling. Also, watch the motor end. It would
be easy for the bell to rub against the heat shrink of the lead out
wires if it were located incorrectly.
The performance of this motor is great! Smooth startup and running
thanks to the 12 pole/16 magnet setup. It is wound ABC ABC ABC ABC. I
tested this motor under load on 2, 3 and 4 cells (300mah - 20C) and
it ran faultlessly on all of them. I also ran it on a 3 cell 400mah
20C under loaded with the same result. Smooth throughout the throttle
range. For the price this is a fabulous little motor and you are
getting a bargain! My initial order was for two and after testing I
now know I can safely order more for my Micro models.

Nice and tough little motor.
I use the GWS 4x2.5 @ 9V. Current was 1.3A. It sure works fine with 3s
LiPo too.
But the bell nearly scratches the shrinked wires and the grub screws
are so small, I wish UH would include the right tool for them. Or at
least recommend to buy it.
Ray Williams
I have just test flown my own design with this great little motor.
300ma 7.4v 2x4.5gm servos, 12amp controller, 4x2.5 GWS prop, prop
adaptor from Homefly 1.5mm to 4mm, it fits the prop very neatly and
GWS 6 channel short aerial. Total weight 74gms. After 6minutes of
trying not to go out of sight the battery was only half discharged.
I share the concerns of others with regard to the position of wires
from the windings but, I cannot see any other means on a motor so
small. I have made sure that the controller is firmly fixed to prevent
any movement of the wires on the motor. For modellers who love
"small" this is a great step forward. The next item needed
is a very small 4 amp controller.

Super little motor. The precision firewall mount fits great in most
tight spaces. Worked great in my indoor flyer.

You guys are amazing I just mentioned to a friend yesterday that you
would probably come out with a micro light brushless ,crazy cheap
motor soon and this morning I check and there it is :-). Just ordered
2 more
Robert Groysman
Great little motor... getting a few more!
Wesley Phelps
love this little powerhouse I have mounted it in a Cox warbird f4u
corsair with a 5X3 GWS prop rock solid at 2.9amps on a 300mah Polyquest 20c 2s pack went as far to put on a 5X5
Gunther prop and wasn't bad am still experimenting but great little
motor will order
more soon and looking at the 5 gram 1 also to try
Put a 7 x 4 prop on it and a 2 cell and it pulled 4.1 amps and 31
watts. Looks pretty good. I have no doubt it will swing an 8 x 3.8.
Guy Weiers
This motor is made very well. For such a small motor it has great
power to swing anything under a 8x6 propeller.
Michael Reynolds
On a 3S LiPo with a 6030 or a 0543 it draws 4.8 amps and pulls
nicely.
This is also a great one to rewind for higher KV and smaller props. I
did a 18T 26AWG delta that came out to 3300 KV and did over 50 mph on
my mini-wing with a 4040 prop.
Mariusz Pawela
This motor is made very well and has great power.
Bare
Received my Tiny Outrunner.. Beautifully machined, Windings are a
bit sloppy though. I had intended this for a Gunther 6x3 prop. Tried
it with an APC 'E' 6x 4 and, by observation, on 3s it spins/pulls
harder than my 6v S400 on 3S !?..No.. heating issues whatsoever.. In
simple terms it means this little rascal is a direct replacement for an
s400 ! at least on Direct drive. A performance increase and significant
weight loss for your s400 warbird model.
Albin Törnqvist
This motor gives a lot of thrust and long flight times with a 4x8
prop on 2s 500mah! I run it on a small parkflyer called "nutta"
and it flies great!
Achim Stegmeier
As said, nicely finished.
Weight 18.0 g including the mount.
The connecting wires are flexible. The supplied prop-mounts are nicely
made although the spinner type one is a bit on the heavy side with
2.5g.
Keep in mind that you will need a 1 mm Inbus for the mount, which is
not too common.
