Default SuperFly meets UltraFly

Hi all,

No, it's not a cheap "B" movie like it sounds but rather a review and test of the [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXJVC1&P=0]Ultrafly Model B/06/10 Brushless Motor[/link] using the [link=http://www.rcuniverse.com/magazine/article_display.cfm?article_id=161]SuperFly Electric Wing[/link] as a host for the upgrade.

Specifications:
Shaft Length: 0.45" (11.5mm)_
Shaft Diameter: 1.8" (3.17mm)
Motor Diameter: 1.3" (32.5mm)
Motor Length: 1.6" (41mm)
Distance of mounting holes:16mm & 19mm
Mounting screw 3x3mm
Maximum input power: 180 watt
Maximum operating temperature: 100C
Magnet: Neodynium (150 C temperature tolerance)
Max Amp: 12A
RPM/Volt: 1000
Weight: 1.48oz (42g)

The Ultrafly Brushless B/06/10 Motor requires a brushless ESC and is precision CNC tooled with hi-quality materials which allows the motor to operate at higher RPM without vibrations. Ultrafly brushless motors have a one year limited warranty from the date of purchase.

The B/06/10 motor is a 180 watt class motor that can handle continuous currents up to 12 amps. It works best on the following plane types and prop sizes.

Planes Weight Prop size
3D 450g,16oz 9-11 inch
sports 700g,25oz 8-10 inch
hi-wing 1kg,35oz 8-10 inch

After plenty of abuse, my brushed Speed 300 motor is worn out in my [link=http://www.rcuniverse.com/magazine/article_display.cfm?article_id=161]SuperFly[/link] Delta wing. My gearbox was also replaced once, and, since I love how this wing flies, I decided it would make a good host for a direct drive brushless motor. No more gears or brushes to wear out!

To mount my Ultrafly B-series motor, I used an [link=http://www.hobby-lobby.com/motormt.htm]MCD400S[/link] Square Speed 400 mount from Hobby Lobby. The motor is held to the mount using two M4 screws and the cooling holes line up perfectly!

I used a [link=http://www.hobby-lobby.com/jetiblue.htm]JESAP18W Jeti Advance PLUS ESC[/link] that comes with the Programming Card for easy setup. The Jeti ESC can handle 18amps continuous current.

The mount was epoxied in place and then supported on the top with two plywood posts. The Ultrafly B-series motors have built-in prop-saver adapters that allow you to easily attach an APC slowfly prop with a rubber o-ring.

Default RE: SuperFly meets UltraFly

Using an APC 9x6 SF prop, I tested the B/06/10 motor using Kokam (15C) 1250 packs.
[ul][*] 8.7amps, 60w, with 3.1oz 2-cell Kokam 1250mAh pack[*] 17amps, 180w, with 4.2oz 3-cell Kokam 1250mAh pack
[/ul]

The 3-cell Kokam pack provided the burst power I needed and created a power system that was just right for the motor and battery ratings. The 15C 1250mAh Kokam pack can provide 18amps continuous and the Ultrafly B/06/10 motor is rated at 180 watts.

The B-series outrunner brushless motors from Ultrafly are a good match for small parkflyers like the Great Planes Flatouts and Ultrafly Extra 300. All three winds are 180 watt class motors that can handle various prop sizes from 6" to 11" depending upon the wind (or last number).

The shaft diameter is 3.17mm and you can flip the motor around to use the built-in prop-saver adapter.

I'll test the new motor out in the SuperFly wing and post a video soon.

Just curious Greg,.. why did you drill and tap the 3mm mounting holes for 4mm bolts? Don't you just love typos

Oh yeah! The screws I used are M3, not M4. I'm not sure what size screw comes with the [link=http://www.tim.mcdonough.net/]Tim McDonough[/link] laser-cut mount. Something for Speed 400 mounting I guess.

The Ultrafly B/06/10 motor was a total success on my Superfly wing. You can see for yourself on my video below.

Greg,

Thanks for all of the great reviews you do for RC Universe. I have been flying a Superfly-E for some time now. I just duplicated your install of the Ultrafly B/6/10. I am using the new Electrifly Silver Series 25A brushless speed control. In your review, you mention your motor pulled 17A on a 9x6SF prop. with the 3 cell Kokam. This exceeds the motors max amps of 12A, but equals the 180 watts. Is it safe to exceed the max amps that much?

Also, how much run time do you get out of the 3 cell 1250mah Kokam?

You'll find that full throttle is rarely used, if ever. The design isn't meant to leave the stick at full throttle but to have tremendous burst power when needed. The offloading in the air combined with excellent cooling and a voltage drop after flying a few minutes keeps the motor safe.

Flight time depends on flying speed and maneuvers. You'll get at least 10 minutes because the current draw is normally quite low.

Good luck!
