  2. Test flight with Holybro Kopis 1 powered by Tattu 1800mah 4s 75c lipo battery Tattu 4s 1800mAh 75C Li-Po battery review: This battery comes well packed with charging plug protector and safety instruction. At first look it seems very well made with good quality terminals. Battery pack measures around 90 x 33 x 30 mm (L, W, H). Due to the the aluminium envelope, the Tattu 1800 mAh weights a bit more than other 4s Li-Po batteries with same capacity. After a bit of research I found out that this producing technique provides not just better heat dissipation and impact resistance, but also compression, in order to minimize puffing during high discharge. Tattu 4s 1800 mAh 75C battery technical specs Suitable for FPV racing drones; Minimum of 1800 mAh storage capacity; 4 cells of 3.7v. Total voltage of 14.8V; Total power of ~ 26.64 Wh; Up to 5C charging rate (do not exceed this value!); High discharge rate (75C); Max Cont Current of 135 A; Maximum burst discharge rate of 150C; Max Burst Current of 270 A; JST-XH charging plug; XT60 discharge (drone) plug; Net Weight: 198 grams; Dimensions: 90.30 x 33.27 x 29.90 mm (L W H). Battery came about half charged (48%), which is recommended for storing. I measured 15.34V on the XT60 plug. Cell 1 – 3.83V, Cell 2 – 3.845, Cell 3 – 3.83V and Cell 4 – 3.83V Is it worth to upgrade from 1300mAh to 1800mAh? In order to make a fair compassion I used same charger (SkyRC iMAX B6 Mini) with same settings. Both batteries I used for the test had less than 10 charging cycles. Firstly, I fully discharged both batteries, rest them for 1 hour, then charged them up at 0.5 A. As you can see in the comparison table bellow, the R-Line 95C finished the discharge process more balanced. At the end of charging, both batteries were well balanced. The two batteries remained cold during the charge. In order to test how these two behave in the real world I used my Kopis 1 racing drone. I tried to fly them with similar amount of throttle in order to get the most accurate results. As I’m not a Pro racing pilot, I haven’t noticed significant performance dropping from 95C to 75C while flying at top speed. Also, the extra weight doesn’t seem to be an issue for the 2450KV brush-less motors. Frankly, it’s hard to get an objective measurement of true “C” rating without professional tools. I ended my test flights when OSD shown 14 volts (~ 3.5V/cell). While my flight with the 1300 mAh LiPo lasted about 5 minutes, the one with the Tattu 4s 1800 mah ended after almost 7 minutes. Unfortunately, I forgot home my infrared thermometer and I can’t confirm if motors and ESCs became hotter after the longer flight. Conclusions Unless your are a pouch-out fanatic, the “only” 75C should be just fine. Personally, I found the battery powerful enough for most flight maneuvers, including repeated flips and rolls. Compared to the 1300 mAh LiPo, this Tattu 1800 mAh 4s 75c lipo battery offered more than 1 minute of extra flight time. IMHO, for practicing, the extra capacity/flight time is welcomed, but if top speed and agility really matters, you should stay on the lowest capacity that you need to finish your race.
  3. Here, I share my experience about how to diy a fast drone. In the past, I used QAV 250 frame equip with 1806 motors and 3S Lipo battery can fly very fast; and now I use 2205/2305 motor, come with small and light frame, DALRC6045 propeller, the speed get 185km/h. It is very important to choos your drone parts, these are my experience of how to choose drone parts? Motor: I have used many different motors, and these are some of I used. 2205 motors: equip with dalrc5045 3 propeller, their thrust is about 1200g(motor’s weight is about 30g, 4 motor is 120g) 2206 motors: I have used it, the weight is too heavy, hard to turn the corner, and the speed is not increased significantly; 2305 motors: this is my new test motors, and the thrust is very good, they’re super smooth and have a good power! For choosing drone motors, I think T-motor is better than others, most racing pilots are choosing their motor. Frame: I have three requirements for select the frame: Light weight; Small wind resistance; Strong and solid; In the past, I sued dalrc220 frame because it is strong and solid, and needn’t consider the weight, now I like the new frame xr220, because it is light, strong solid and small wind resistance. If you don't know frame or how to choose frame, you can read this guide: Quadcopter Frame Sizes Guide ESC: I think the most ESCs have no difference, the program are similar, you just need consider the price. I’m using the 30SA ESCs, in order to match my 2305 2450KV motors. Battery: To flight fast, a good lipo battery is very important; low C rate can’t discharge high current, if you want to flight fast, you need at least 60C or more lipo battery. How to choose high discharge rate lipo battery? I recommend you can choose this Tattu drone lipo battery, best power delivery, autonomy, reliability, long life and less sag than any other lipos, and most FPV pilots are using their battery. I have built many FPV quadcopter, and this is one of my FPV quadcopter’s build parts; Frame: XR 220; Motor: T-MOTOR 2305 motor Propeller: dalrc 5045 3 blade propeller; ESC: BLHeli_S 30 AMP ESC; Camera: Hsh1177; Lipo Battery: 1300mAh 4S 75C Lipo battery; Flight Control: F3. What do you think about these? Do you have any other tips to add?

  5. This Quadcopter Syma X1 is meant to be used not only indoors, but also outdoors in calm weather. A very lightweight construction helps prevent damage in case of small accidents that may occur during training. Main Features: • Very light • Durable frame • Resistant to damage All electronic components are located on a single board. Charging the copter is implemented via a USB cable. The 3-axis gyro with adjustable sensitivity gives the Syma X1 a perfect stability. It is also capable of performing the 360 degrees flip (upside down). The flight time can be up to 4-6 minutes. Technical Specifications: Power supply: Battery Li-Po 3.7 V 350 mAh Type: Quadracopter Flight range: 40 meters Engine type: electric Remote control: 4-channel Height: 60 mm Diameter: 260 mm Country of origin China Principle of operation The copter is equipped with four electric motors on each propeller. It incorporates the 3-axis stabilization of the copter during the flight. The execution of the 360 degrees flip will require some training, but fairly easy to implement. Light body with Lexan protects against impacts to the board electronics. Use and storage The remote controller is simple to operate. The Syma X1 quadcopter is fairly stable, thus it is ideal for video recording and even for children usage. The Syma X1 is controlled via the four channels, just like any four-channel helicopter: RPM (height), pitch (forward, back), Aileron (roll right, roll left), rudder (turn left, turn right) To extend the flight time you can order a couple of spare batteries, which are very cheap. It is best to avoid flying the copter in strong wind conditions.
  6. Hey y'all! I'm from PR and got started on RC flying about 2 months ago and due to my time availability and lack of people who are willing to help, it has taken me a while to learn. Any tips are more than welcome. I'm also available to anyone that would like too come over to my little island for any type of activities, drone related or not (everything is better with DRONES).
  7. Hello to all the drone enthusiasts, I wanted to give you a heads up, that we have just launched a "Drone Challenge" on SimScale with a 3D printed assembly of a drone as an award for the top three submissions. The goal of the challenge is to optimize the design and performance of a 3D printed mini quadcopter by either applying changes to the propellers or modifying the design of the arms in the structural frame. Participants will be able to validate the results of their design changes, such as increase in the lift or reduction of the weight virtually, using the SimScale platform. All the winners will receive a 3D printed assembly of their drone, which they can then build at home. On top of that the first place winner will be awarded with a simulation training and a 1 year subscription of a SimScale Professional plan, which will grant him access to all simulation features and 3000 core hours that he can use for private projects. The submission deadline falls on the 29th of February 2016. More information about the "Drone Challenge" can be found here. Hope to see some great submissions from you - Agata
  8. So I'm building a 450 class quadcopter and purchased the multiwii pro ez3.0 from readytofly quads. Everything looks pretty straightforward to hook up. The transmitter I purchased is a Devo 10 and I upgraded the firmware to deviation 4.0. The receiver that came with the Devo is an RX1002. The question I have is can I send the telemetry from the FC through a channel on the receiver or do I need to get something like the lemonrx with telemetry? I've posted this question on a couple of forums and still don't have an answer. Thanks
  9. I started working on my first Quadcopter but what the problem is one motor is stopped when the throttle increase i can't figure out the problem
