Build: Night Hawk 250 Pro

DSC05904

The Best Hobby Mall’s Night Hawk 250 was our first venture into 250mm class quads. It had a nice introduction price of $39.99 USD with free shipping and it’s really non nonsense free shipping. We got it shipped to Singapore.

Rebuild 2 – 9 Dec 2014

Rebuild it and flown it with a Hobbyking Naze 32 (This is the soldered horizontal pins version. There is a vertical pin version and a no pins version). Great fun as well. Picked up a pack of spare accessories that consists of all the bolt, nuts and blue rubber thingy as well.

The ESCs didn’t like being cramped together and we learn the hard way. It just never flew properly. After one ESC discarded and all moved to the arms later, we were flying again.

Rebuild 1 – 15 Sept 2014

It never flew properly on a KK2.1.5, gave up and anxious to fly it, swop to a DJI Naza M Lite with GPS. yes, a little crazy with the GPS and all but it flew great!

7 April 2015 – Naze32

After. #hobbyking #afroflight #naze32 #acro #abusemark #funfly hahaha long product name.

The Nighthawk 250 has another change and it’s to Naze32 this time. We picked up the Naze32 from Hobbyking. Bluetooth What you must buy, repeat MUST, when you get the Naze32 is the Bluetooth module and while at it, pick up a buzzer too, we reuse the one from our KK2 board. Once flying stable on default PID, all you need to do is change the rate for roll, pitch and yaw. Here’s ours, change from 0 to 0.50 then finally to 0.8 and you’ll be flipping with great fun without loose altitude. Screenshot_2015-04-14-21-46-25 Android Apps


The above is EZ Gui Ground Station. Pay for it, trust us. It’s great. The first one we tried was the Naze32/ MultiWII Configurator but it can’t read (as of 15 Apr) AUX 2 that we setup for Autotune.

Flip!

Build: Aliencoptor 430mm

The Hobbyking Aliencoptor 430mm is one of the nicest frame thus far that we have built.

Following from Hobbyking product page. This is the 430mm version. Aliencopter has another 470mm version that folds slightly different here. Here for people who can’t see the page. We still cannot figure why they don’t like traffic from Singapore.

It got us getting out Paypal account ready when we recently crashed the F330. Got another team member, the Mrs. to rebuilt that while this Aliencopter gets built too.

The manual is horrible. So here’s better pics! We can’t vouch for better words but it sure is better with the original manual having little and quite useless instructions.

Top Chamber

Build up the top chamber first and the stand offs. Leave the upper most plate off for Flight Controller installation.

Put in the 8 red standoffs. We swop out the screws after the first few flights. They are simply too short to be able to hold the top plate nicely and it keeps coming off ripping the threads away from the tip of the short screws.

Arms

Install the standoffs on the arms. Note that these 4 standoffs are packed separated from the above 8 pieces with it’s corresponding screws.

Install the motors. We migrated some DJI 2212 from the last Reptile Build here. It already has nice long cables that we tuck below the arms then back up again, later to the ESCs. We removed the DJI and mounted EMAX as the DJI can’t take some standard propellors the emax could. The center hub was thicker at 10mm.

Run the cables on the outside so when folded, the cables dont come into place and get sliced.

Bottom Assembly

Install all the teeny tiny screws and standoffs on the bottom plate. We like to have the “arrow” design pointing forward but it’s no difference since it’s a quad. If you have any preference like us, you have to decide now so it’s tidy.

Power Power Power

Install the PDB. We made use of the existing one from myrcmart since it’s a nicely solder with 4 x 30A Opto from DJI. Just made use of some standoffs. There are some transparent nylon screws with nylon nuts and standoffs. These are all for the Aliencopter PDB that came with it. Do not use metal standoffs. We skip using the provided one as we have existing ones. The provided Aliencopter one has blue LEDs like what we ordered separately from Goodluckbuy and installed on our Alien560mm.

Put in the bottom plate 2. We only screw in 2 center screws right in the middle for now for adjustment. Layout the ESCs. Put in the arms Screw in all bottom screws. Completed.

In the field

packed

We brought this quad to St John’s Island and the neighboring island and it’s a blast to fly it around but the constant dismantling and assembling of the arms is really frustrating.

Being on the island, we decided to simply strap it on the bag and walk around with it out of the bag, assembled and ready to fly. It doesn’t cause much alarm with the whole quad in the open as these island are only full of anglers and a few tourists.

Gimbal

Our contraption works great using only cable ties, strapping the dismantled Tarot T2-D gimbal to the front of the whole quad.

We used the Hobbyking single cable to do “traditional” setup of the Naza M V2.

End

The most irritatant was the constant assembly of the arms and dismantling of the arms. The size is generally the same as compared to the ATG 12 inch foldable quadcopter but the ATG using Tarot type catches that do not require removing screws to be ready to fly.

Next up

– 3D Printed front gimbal mount to replace the zip ties
– Repositioning of the GPS, video transmitter and receiver into the cage

overall more space at the back for the GPS and the Lipo can be pushed all the way to the back to counter the weight of the gimbal at the front

morespace

– Try out with 9047 and 1045 propellors hoping to get a little more flight time. We average 10.5 mins now with the gimbal and a Turnigy 5000 mah lipo

RCX GF223 Build

This is one fun build by The Mrs. She took her time and meticuliously tidied up the cables. The difference between men building a quad in the team and women building it.

Men in the team are untidy and get it to fly first then worry about the looks of it. Women seems want to build it tidy from the get-go hahah

Cheaper alternative to the nut that was surely to go missing…

5mm nut. SGD$2 for 10.
