I would have thought as well, going up in cable size would negate the voltage drop on any platform. That is likely what kills the ESC. But if you are running good quality cables for the ESC and with sufficient core size to take the ampage with a 1% voltage drop (or less), then it should be fine.

When i did the numbers on mine, you could do 0.5m cable runs with 1-2% voltage drop on 3S, let alone the 0.05m runs I plan to use.

On 4S with a 30A ESC I was strongly recommended to use 3S (though mine is a 2300kv), all this to learn with wings too now… ergh!

I actually bought a 50A ESC so can 4S the thing and have some wiggle room. I’m planning on using Lipos, I guess Lion might be OK?

Actually just noticed it’s soldered to a 40A ESC… Re use that too :wink:

I bought 5 of these too, instead of the banana plugs. MT60 (XT60 for motors)… See how we get on!

An interesting one for you, watts = volts x amps.

So as you go up cell count the actual current draw will drop for the same power output…

So higher cell count does not mean you need to increase the max current rating of your esc.

I’m considering selling my 3", built it and have only flown a couple of packs on it. Don’t have a regular spotter, and the thing is hard to fly VLOS given it’s size.

Thing is I got a fair few of the parts second hand, and I know it’s not the latest and greatest, so no clue how to price it. Since we’re all trustworthy on this forum (:wink:), I thought I’d ask here what I might expect to get before listing it in B/S/T. Specs are:

  • GEP-MX3 Sparrow (without LED’s)
  • Mamba F405 v2 (older version with micro USB) + F25 ESC flightstack.
  • FRSky XM+ (I think) receiver
  • TBS Unify Pro Nano VTX
  • iFlight xing 1408 3600 kv
  • Runcam Micro Eagle

All worked fine last I tested but can’t say I’ve ever really put it though it’s paces.

Fly it, shoot a video, add video to sale thread. if it flies, then you have one up on people who don’t bother.

As for how to price it to sell. Add the cost of the parts and divide by two is the quick and dirty approach. But I haven’t sold any of mine, nor ever would. Much too fun to fly.

Has anyone used gps on softserial? What baud rate did you use? Did you just connect the gps tx wire?

I recently used 36400 or whatever it is and worked ok.

F411 btw

Deffo on softserial? One wire, the tx to fc rx?

Yes as Rx and hdzero were connected to the two real uarts

where you guys buy your pin headers, plug housings and pins from?

got a crimping tool from amazon and the plugs and pins that came with it are utter trash they don’t clip into the connector housings very well and are loose.

throw me some links guys to buy the pins for crimping and the connector housings looking mainly single doubles 3 pin and 4 pin housings.

I’ve got stock you can have mate, will put a selection in a bag and drop them through your letterbox today

This is a good set for making cables to attach to flight controllers, ESCs, etc SH1.0 is a common standard on quads.

For cabling needing inline plugs/sockets I usually use this sort of thing. I keep plugs and sockets with several different numbers of pins in stock at any one time. I shop around for the best deal. Some devices (eg GPS) have sockets of this size on them as well, so it’s a good choice.

I think UnmannedTech has a load as well.

Note that in each of the above to remove a wire, lift the tabs (carefully) with a craft knife and pull the cable out.

This is why I love this club! with in hours of posting about connectors and pins this little bag landed on my mat.

Absolute legend @Steviegeek you really are a legend man thank you.
