Official SunnySky x2204s 2300kv versus BangGood’s

I purchase some nicely priced SunnySky x2204s 2300kv from BangGood for < $16.

Here’s a photo comparison against the x2204s purchased from SunnySky’s official US distributor: BuddyRC.com

I see that the one from BuddyRC uses thicker motor wires. And are generally neater wound versus the one from BangGood. The BangGood one has a thicker bell cross section, so you can’t see the magnets like you could with the original from BuddyRC. It also seem to use more glue to keep the magnets in place. I am not sure if this is in response to reports of magnets coming loose…especially those who are running these motors on 4s lipo.

The BuddyRC motor has a slight sheen to it. With crisp lines and a reflective, copper/light gold logo. While the BangGood motor has the SunnySky logo in a matte white, with a slightly different font. The motor bell is painted a more matte black. And the line noted in the picture below wasn’t as refine.

I also noticed that the BangGood motor has a shorter threaded motor shaft. This is interesting because SunnySky x2204s motors are known to already have a slightly shorter shaft than comparable motors. i.e. Cobra 2204.

At the bottom of the motors, the BangGood version has very obvious concentric rings.

Another obvious change between the motors is the use of a metal washer in the BangGood motor. Compared to the plastic one.

Another top view of the motor windings, looking into the stator/magnets.

And the same thing from the bottom of the motor.

At this point, I do not know if the SunnySky x2204s motors from BangGood is a knock off or just the latest production run. The only way to tell is getting official word from a SunnySky representative. Or grabbing the latest copy from their official US distributor: BuddyRC

In either case…my own opinion is the older SunnySky has a more premium look to them than the one from BangGood. On that merit alone, I would consider some of the other competing 2204 2300kv motors at the moment.

I will be putting these BangGood motors on Fyathyrio’s test stand to see how they compare. So stay tune for that.

WK-Devo-S-MOD Module for Devo7e

For those who attempted the Devo 7e range mod and did not succeed. You can purchase one of the upgrade module made for the Devo 8 and 12 to get your Devo 7e up and running again. With full range. :)

BangGood still carries it for < $15.

Here’s a picture of it installed. I removed the original and installed it in it’s place.

Devo 7e Swivel Antenna Mod

I just added a swivel antenna to the Devo 7e’s stock antenna tube. I cut and tapered the stock tube. Then used a coax to extend the connector, so I can mount at the new location.

The ability to adjust the position of the antenna will optimize the RF radiation pattern. Ensuring you have a good signal to your model. Combine this with the Devo 7e range mod. Or you can buy and install the Walkera Devo S upgrade module to turn the Devo 7e into a full range radio transmitter. This is the same module you would need in case you attempted the range mod and failed.

Soma’s WarpQuad

Just gonna share photos of the acro quad I am building. Thanks to Soma for coming up with the WarpQuad. Looks the best out of all the acrobatic quads out there.

Here’s the center frames. It sandwiches the 4mm carbon fiber legs.

soma_warpquad_center_plate_ninja_stars

 

I switched out some of the hardware. Such as the aluminum washer below. And used power cables that comes attached together. For a neater run of the brushless motor wires to the center of the WarpQuad.

soma_warpquad_motor_wire_routing

 

Another change from the standard build out. I added 1.72mm washers so I can run the 22guage motor wire underneath the top plate.

 

soma_warpquad_flat_motor_wires

 

Then I modified the XT60 lipo connector so that it can be sandwiched between the frames. Filed down the connector so it can conform to the curve of the top plate.

soma_warpquad_XT60_connector_location

 

You can see where the power distribution harness will solder to and subsequently run to each of the ESC.

soma_warpquad_XT60_connector_location_topdown

Those were the early photos. These upcoming photos are where the WarpQuad build out is at now. It took forever to source red aluminum washers with the same bevel as the blue ones I had on hand. Still not perfect but very close. The aluminum TeeNut that the frame is resting on is just to temporary hold the arms in place. And make it easy to disassemble without tools. This frees up my hand to ensure the cable runs are neat and nothing is pinched.

I switch to button head screws. Red aluminum 5mm. The hex size will take the same allen wrench to be consistent with the rest of the screw head used on this quad. The four button head should be strong enough to secure the motor.

daryoon_soma_warpquad_build_motor_6mm_red_aluminum_button_head_screw

 

Here is a closer shot of the red washers and where I intend on placing the ESC. In the center of the quad instead of on the arms like the reference build out by Soma.

daryoon_soma_warpquad_build_countersunk_screw

 

A look at the cable run and how it meets up with the brushless motor. I created a stagger cut because I didn’t want to seperate the wires to fit heatshrinks. The stagger will keep the wires from shorting. As extra precaution, I applied Liquid Electrical tape to insulate. Then follow by a larger heatshrink to cover up the area. To dress up the heatshrink…I used chrome tape and nail art tape. This brings some blink down to this end of the arms.

Additionally, I hope the chrome take will help reflect some of the LED lights up to the props once I place one there.

daryoon_soma_warpquad_build_motor_wire_dressed

 

Here is a look at the stagger cut I mentioned before. Some folks have asked why I choose to use four motor wires when brushless motors only require three. The simple answer is for symmetry once it gets to the center of the frame and have to go to the left and right of the screw.

daryoon_soma_warpquad_build_motor_wire_stagger_cut2

 

The quad is ready for the ESC to be soldered on. Easy to do. However, I need to figure out how I want to route the power wires and still have room to fit the Flight Controller between the frame. There’s really no room for both. :)

Hobby King HKing 10a Brushless ESC

Lovely spring weather means I am antsy to build and fly again. I am planning on using this Hobby King HKing 10a brushless ESC in a 230mm size acro quad. Not sure if it will be able to endure SunnySky 2204 2300kv with 3s lipo but I like the physical size…so I will give it a try anyways.

HobbyKing_HKing_10a_amp_brushless_esc_actual_dimensions_measurements

Anyways, the dimensions on Hobby King is incorrect (23mm x 18mm). Here are the actual values as measured with the digital caliper. The bare ESC as pictured weighs 2.59g.

It arrived with 20guage silicone wires for the main power. And 22gauge silicone wires for the motor leads.

Missing from the photo is the electrolytic capacitor (100uf 16v). I took it off so I can use a tantalum SMD capacitor with the same values. It’s much smaller physically. Hopefully it works out. :)

What I like about this ESC is the fact that it’s BLHeli compatible. Plus, it uses all N-channel MOSFET. And it was reasonably inexpensive at $5.78.

v911 Pro Brushless

Just stuck a brushless motor into the v911 pro frame.

Flights felt underpowered. I think it will need a larger pinion. I didn’t play with it too much so I can’t tell if we can get the v911 to actually fly better. Additionally, you’ll need to reinforce the main frame after cutting away the vertical struts to make room for the brushless motor.

My 1S Charging Station

Just wanted to share my new 1S LiPo charging station. I took a 1s Micro parallel charging paraboard from Hobby King and mod it to become a serial charging board. I think this paraboard would be cheaper and easier to mod. Plus, it does not have the LED that drains the first lipo cell if you don’t remove the lipo right after charging has completed.

With this mod, I can use the balance port of the charger to individually charge each cell. I can charge from 1 cell to 6 cells.

1S_serial_balance_charging_para_board_mod_hack

 

Here’s a closer look.1S_serial_balance_charging_para_board_mod_hack_closeup

Here it is, charging two 150mAh LiPo. The stick the temperature probe near the cells so the iCharger could monitor the temp and be able to shut down the charging if any cell rises to unsafe temperature.1S_serial_balance_charging_para_board_mod_temp_sensor

And here’s how you configure the board if you were to charge 3 lipo cells. You simply move the positive lead to the last cell. I like it because I can charge all the various connectors normally used with 1s LiPo.

1S_serial_balance_charging_para_board_mod

You can also charge different capacity LiPo together. But for safety, you would limit yourself to the charge rate of the lowest capacity connected lipo. Not a big deal if you have the time. Otherwise, it would be better to charge cell combination with similar capacities.

Hope that inspires you with your own mods.
