    @Pavel I do not recommend using this servo as, although it says metal geared in the description, not all the gears are metal… There is a gear made of nylon in cheap “metal geared” servos.

    I know you want to replace the expensive servo you had with a cheap one but I really recommend you don’t do this as it will very easily break even in a light crash. You could argue that because it is cheap, you can buy it again but, I know from experience that you will spend more money buying multiple cheap servos than a few higher quality ones 🙂

    The HK15148B servo will not fit the servo mount and you will have to do the servo mount mod shown in the V3 build video/ FliteTest Tri. build. I recommend using this servo from Hobbyking. I have good experience using this and can confirm that it is almost exactly the same as the BMS servo. (Even David recommends it)

    Hope you will be able to fix your copter soon and get it back in the air!

    If it helps and to add on to Michele’s comment, try changing two of the wires from the motors to the ESCs. This will change the direction in which the props move… Match it to how your flight controller prefers it to be (preferably)…

    Looking at your images provided, you are using a KK2 board, so you want the front right to turn clockwise, the front left to turn counter-clockwise and the back motor to turn clockwise.

    If you do not have propellers that is meant to turn in the desired direction (e.g. A CCW prop on a motor meant to turn CW), make the motor turn CCW by switching two of the wires from the motors to the ESCs. In a tricopter, it is not critical on the direction in which the propellers turn. It just has to blow the air downwards… So, you can put CCW propellers on CCW motors or CW propellers on CW motors or vice versa.

    P.S. CCW means counter-clockwise and CW means clockwise. Sorry, if this sounds too basic for you but just in case you did not know this… 🙂

    If it is still not lifting, try to use a bigger diameter prop. Make sure you also calibrate your 3 ESCs as well.

    Thanks for replying…!

    I also would like to ask why the mini tricopter has less amount of flight time compared to the V3.5 tricopter. The majority of the FPV videos that I have seen with the mini multirotors are maximum 3-5 minutes while the ones with the bigger size last around 10-15 min depending on the setup.

    This, from my research in the internet :), was true even though the two aircraft had the same exact batteries e.g. 2200mAh and the same exact components (motors, ESCs). Don’t the motors produce the same amount of lift in both aircraft? Surely, the minis would be lighter compared to the bigger sized multicopters? So why is it that the smaller crafts have shorter flight times?

    Maybe it is because the bigger sized ones have more leverage and are able to produce more thrust as the motors are placed further away from the centre??? Maybe, it is because the smaller multirotors move faster? But if they are smaller, they are lighter and are able to move faster more easily than the heavier and bigger ones???

    I don’t know 🙂 Sorry to disturb you with my questions!

    Hi, Tjerie!

    I just wanted to ask what kinds of flight times you get with your mini tricopter… when you use which kinds of battery. Thanks for your great contribution to this site and sharing your knowledge.

    What kind of flight times are you getting?

    Buy another one! … but this time use the metal gear in the another one to replace the plastic nylon gear. Use this video to guide you. This will make a full metal gear servo and you will not have to worry about you servos breaking easily!

    I did this mod and it definitely made the servo stronger. It does, however, become very loud (as all of the gears are metal) I suggest putting some oil or lubricant on it.

    It is bound to do that… Any multirotor has to be trimmed out for you to have a good flight experience. You cannot expect it to work from the start.
    There are a lot of videos on the internet showing you how to trim your flight controller. Do a lot of research and you will have fun!

    Don’t worry, it is a process everybody has to go through to get a good aircraft flying! Even pros like David have to spend quite a bit of time to get the best performance possible.

    I hope you are able to tune it well.

    There was no wing when I got the model, I was hoping I could build it myself… The person who gave the model to me said that he would look for it. The model, however, is currently at school.
    And it is currently a ‘half-term break’ here in England… When I return back, I will provide you with the estimated weight along with the complete dimensions of the model!

    Thank you very much,

    just out of curiosity, which 3D printer do you use… I don’t have one yet, but I do plan on buying one.

    Aren’t the performance of ESCs based on the firmware that they are flashed in… not the actual ESC itself. I would rather buy a cheap esc that has a built-in BEC along with a SimonK firmware that is built for the purpose of multi-rotors, like this one.

    It’s only my opinion and it may be wrong… 🙂 Afro Slim ESCs seem to have good reviews. But David never used these escs in any of his builds, at least they are not in the ‘Projects’ section.

    And from “will be using a normal full size one on the tail for the servo”, I was a bit confused because I thought you meant you were going to use an esc for the servo. -> you don’t, you use escs only for the motors!

    Hope it has helped you,
    (and I don’t mean to offend you in any way)

    COOL! mind sharing the file… Please?

    Maybe you could make files for 5.8, 2.4, 900 etc and sell these.
