Few months ago I was searching for a 2204 or 2205 size low kv & light weight motor for efficient slow flight on small foam plane. The solution I found was either blue wonder type or SunnySky X series 2204 for plane but both was not available in any LHS. I had a Emax 2805 2840kv sitting around since last year which is for 2S & also have low efficiency , then decided to rewind the same. I have rewinded CD ROM motors in the past & also has some wire for transformer winding. I started with removing the stock winding which was three strands of thin wire terminated as dLRK delta. Then followed the winding scheme as per Bavaria-direct. Marked the pattern(clockwise or anti clockwise) on the slots & started with 26 SWG single strand wire. The goal was to put as many turns I could to get a lower rpm/volt. I finally able to wind 15 turns on each slots.

Hello everybody,
Before starting the post I would like to tell that I have dealt with Mr. Vineet Sharma from 2016 since he used hobbysea later used hobbyxyz & never had a major problem, he seemed trustworthy & also recently came to know that he was seriously ill. I am also concerned about his health & really feeling sorry to share this.

I needed a flysky Tx & had a whatsapp conversation on 22th November, he said he currently recovering & shipping normally, I placed the order without a doubt instantly & paid Rs 4440/-. The next day the order status changed to complete without tracking no. When asked on 25th November he could not give the details .After repeated asking he finally called me on 29th November saying that he could not remember he has shipped it or not & said me to wait for few days. After that he stopped receiving my calls, email & whatsapp massages. Noticed that he becomes online at least five times a day but intentionally avoiding & rejecting my calls. Currently 17 days passed & seems no chance of getting the item, I will update if I receive that after this post.
Attached all the screen shots of whatsapp conversation & order status.

I am still very sorry to share this, if he is so seriously ill that he can't talk or process order he should temporarily put a notice on his website & stop taking orders till he completely recovers.  So that others don't loose their money & time like me.

Hi,
Got from Amazon and the details are here below. I initially ordered for supercapacitor, but not received yet. RTF got earlier. but found instead of super capacitor, it uses Lithium battery with charging circuit along with timer and push button. Charges through micro usb port. So you can use powwer bank for maidan charging. You also get 10-20 times of flight of 10 second, after charging it.
Very fun and ultra balastic as the battery is between two wing of biplane wing.
Slide tail heavy, and so glide is not high, but overcomes by power flight pusher at higher wing.

It more than a year my last 2inch was built.
I am aiming for a quad under 250gm AUW with gps and fly using 2 x 18650 li-ion.
I have to restrict to 2s due to weight and with 2s many people told emax 1106 4500kv would give more flight time.

Part used,

130mm dead cat style frame, it can take 20x20 or 30x30 stacks and can take 11XX or 13XX style motors.
EMAX RS1106 II 4500KV motors
Gemfan 3025 2 blade props
Hackrc 15A 4 in 1 ESC.
Matek F722 SE FC
BN-880 GPS/Compass
Eachine TX806 VTX
FrSky R-XSR Rx
No Camera yet.
2 x Sony VTC6 3000mah 18650 Li-ion. These can discharge up to 20A. I think my current requirements would be around 10A

I know the FC is heavy, but I needed one with baro and F7. There wasn't many choice available in 20x20.
VTX too is heavy, soon will be replacing it with light weight 20x20 stackable type.
Dry weight came to 128gm and battery weighs around 103gm.
Yet to do a hover test.

Hi RC people,

I have built my first ever drone and had gone through a maiden flight, result was a crash land. I'm pretty sure that the base parameters needs some serious fine tunings and tweaking, suiting my drone. My drone should possess smooth maneuver, stable Altitude hold & Loitering and RTL during fail safe – these are my expectations and I request your suggestions from your experiences and knowledge.

Suggestions and advice are requested:
1.   What kind of tuning is required for smooth maneuver, stable Altitude hold & Loitering and RTL?
2.   How do I start with the tuning process and what to be tuned?
3.   Is any pre-set values to be revisited initially, before tuning?
4.   Is indoor tuning with strings, help ? (https://diydrones.com/forum/topics/arducopter-tuning-guide)
5.   Will Autotune be helpful for smooth flights, what needs to be done before performing auto tune ?
6.   Also sharing any feedback/ advice/ personnel experience can help me to improve myself ?

Drone Configuration:
•   Purpose:    Photography
•   Frame type:   X- Frame – Quadcopter
•   Frame size:    680mm
•   GVW:       2.8kgs (Drone + 4K camera)
•   Motor:      EMAX MT3110 700Kv
•   ESC:      EMAX BLHeli 25Amps
•   Propeller:    1238 CF propeller
•   Battery:      ZOP 14.8V 4500mAh 45C Lipo
•   FC:      APM 2.8 + Ublox M8N GPS + 3dr Power module
•   Firmware:   Arducopter V 3.2.1 (Last update for APM 2.8 board)
•   Radio:       FrSky TH9X – 8 Channel
•   Telemetry:   3dr 100mW Telemetry – 433mHz

First Maiden Flight:
I had the drone out for a maiden flight with the existing PIDs and the default parameters in the APM 2.8. I had setup only Stabilize mode in all the 6 flight mode options, since I'm not sure how the drone responds to the other modes. And most importantly, I wanted to see the drone's performance in Stablize mode.
It was a mid noon in an open residential plot, the wind was very mild and I had the take-off. The drone lifted-off from the ground at nearly 60% of the throttle. But the wind was carrying away the drone. Since, I was in Stabilize mode – I tried to keep the drone in position. But the drone responded too aggressive to my roll and pitch sticks. I somehow tried to land the drone, coz I do not want to loose it in the wind. I lowered the throttle stick very slowly, but it happened to be a crash land and my propeller got damaged. Then, it was time for the propeller change and I decided to tweak the base parameter (PID gains, Pitch/ Roll tilt angles and any other required fine tuning) before taking them up in the air.

Changes done to the base parameters:

ANGLE_MAX (cDeg): Default value=4500 ; New Value=1000 ; Comments:Difference in tilt angles observed - 10deg
ACRO_YAW_P: Default Value=4.5 ; New Value=1 ; Comments:Now the Yaw rate is smoother and not aggressive as was in default values

Background on the Quad build:  (I've put this session at last, since I do not want to bore anyone with bla.. bla.. stuffs in the first)
I am Arunkumar from Chennai, I am a Mechanical engineer by passion and an Engine calibration engineer by profession. I am so much fascinated to build a drone rite from my college days, but never found time and budget. Its been almost 5 years after graduation now and I decided to pursue it. I started surfing on the web regarding building a drone by late 2018 and almost touched upon every basic topics. And finally came up with my requirement for building a drone, I wanted to see how things look from above. Yeah, I decided to build a drone with capability of carrying a camera payload of 0.5kg or atleast an action cam with Gimbal.
I decided to build an Quadcopter and started to begin with the GVW calculations, with the help of 3D CAD modelling (Calculation part in the next paragraph). I liked the design of Tarot-680 and Alien H4 680, mainly their looks and portability. I wanted the drone to be very portable and have space to mount the camera equipment. I started looking deep into Alien H4 680/ DAYA H4 680 designs and modelled a 3D CAD respecting the basic symmetrical rule for X-frame, i.e. when the axis of the motor mounts are joined by lines, looks like a square whose diagonal length measures 680mm.

I finally built a 3D model of my frame after multiple iterations, which respects both symmetrical rule and fold-ability. I wanted my complete frame to be made out of Carbon Fibre (CF), but considering the availability of CF here in India – I decided to go with Glass Fibre (GF) for the base plate, CF tubes for the foldable arms, aluminium motor mounts, TAROT mounting clamps for the CF tube and a wider landing skids. Since I had the complete 3D model, I was able to specify the density of each material (CF, GF and Al) and could finally get a very closer estimate of my frame weight (~700 grams). Believe me, my drone now weighs the same as the estimated weight. I felt this is quite heavier for a frame along with landing skids, but this was due to the high density of Glass fibre and the M3 Carbon Steel bolts (nearly 40 numbers).

Then proceeded to look for the available Flight Controllers (FC) in the market. Researched on that topic, finally decided to go with APM 2.8. Because, I liked that had a open source platform, compatible for other types of RC vehicles and mainly the budget. Further looked upon for the type of Motor – Propeller – ESC – Battery combinations, considering their own weight that adds to the GVW and matching the thrust provided by the combination. After many iterations, my calculated GVW of my drone was 2.3 kgs without camera.
GVW: Drone = 2.3kgs | Drone + Action Cam = 2.3 + 0.2 = 2.5kgs | Drone + 4K Camera = 2.3 + 0.5 = 2.8kgs
I decided to have my thrust to weight to be 2:1, which is the thumb rule. I chose EMAX MT3110 700kV motor which provides a maximum thrust of 1.4kgs @ 17.3Amps in combination with 14V battery and 1238 CF propeller. The total thrust provided by the motors shall be 1.4kgs x 4 = 5.6kgs, this shall be an exact match considering the critical GVW=2.8kgs (i.e. Drone + 4K Camera = 2.8kgs).

Then, I started procuring the materials and components required for the build (both from India and China). Out of which 90% of the electronics were procured from Aliexpress and the building materials from India. It took almost 6 months for me to collect all the components. Finally my drone configuration was supposed to be as below;
Now, once after collecting all the components, I started to fabricate the frame first, next the wirings, setting up the motor configurations. Fabrication and wiring were one of the very trickiest part in building the drone, my personnel opinion. Because even a single wrong solder can ruin the complete setup. I referred to the "Flight Setup" from the Ardupilot website https://ardupilot.org/copter/index.html and after few reworks, I finally built the complete drone. Yet, the calibration part was left out.

I started referring to the below tutorials for each;
Radio TX/ RX Setup:
TX/RX – Flight mode switch setup: https://www.flitetest.com/articles/Turnigy_9x_and_Arducopter_flight_mode_setup
ESC Calibration:
APM Setup: All the 8 parts of Painless 360 channel

Firmware uploading, Compass Calibration, Accelerometer Calibration, Radio calibration, Fail Safe setup and other Mandatory calibrations were done. Successfully !!!

Hi,

I have a Walkera Devo 7 Transmitter and its original receiver for sale. I have purchased it last year. But i am not using it at all. I have hardly used it for 3 to 4 times, Not more than that for sure. It has the original box. Attached Pictures for your reference. The price is Rs.6000/- plus shipping.

Thanks
