pepperFIISH — 2S prototype thrust testing video

I finally found some time to take my new 2S version of the pepperF1SH quadcopter for a walk fly:

It was quite gusty that day but most of the time I did not notice it in flight. This was just some thrust testing, turn on the speakers, it sounds really creepy for such a small copter. The copter in the video weighted in at ~38grams including battery and all FPV gear. The battery was probably too weak, I used two of my turnigy nano 200mAh batteries in series. I am not sure if that one can cope with 80C bursts… I will probably switch to the turnigy nano 300mAh 2S packs soon 🙂

    Hi,
    What is the absolute miniturized size for 3s ESCs you think is possible with current components for 8-9A?
    Eachine offers one 20a but 20×20

    Do you think 16×16 is possible?

    I know the current bottleneck are the lipos.
    but gaoneng gnb is currently the leather with 80/160c & 350/400mAh. so you know what I’m going to tell you. Next level: dys 1104 6500/7000 on 3s.

    Greeting from Vienna.

      I think 3S on 16×16 will be hard. Maybe some day in the future. For now I am working on the 2S version 😉

      Thanks for the number! Thats 5% of the copters weight… I think I will stay with the JST PH2 for now (they are rated at 2A :-X).

    That punchout is scary ! This is going to be awesome 😀
    I think the connectors on the battery should be changed to something that can take some more amps 😛

      I use the JST PH 2.0 connectors (2 and 3 pin versions). I had those on my LKTR120 and they seem to work quite well. I do not like those red JST connectors, they are so hard to separate. Any recommendations?

        Simon I agree regarding the difficulty in separating the JST but they are a more robust plug with a higher current carrying capacity than the Micro Losi / Walkera style. I have found that you can file down the sides of the plug a touch to make pulling them apart much easier but yes we should not have to resort to this.

          The original JST PH 2 are rated at 10mOhm (or 2 0mOhm after repeated use). This should be ok for our application. Hovering current should be quite low.

        According to the JST-Connector page on wikipedia the VH series is rated for up to 10A but the connector itself seems to be pretty big.
        The smallest of the 3A capable connectors is the PA series.
        Another alternative would be using 4pins and combining 2 for plus and minus each…

          The idea with multiple pins sounds good. With the JST PH it would give you at least 4A continous current.
