Re: Setting up a twin

Do not extend the battery wires on the ESC's, only use one BEC or a dedicated BEC instead of the ones built into the ESC's. You can extend the ESC battery wires using capacitors, but that makes things more complicated than you want to look at ! I think I understand what you are asking, Opto isolatio...

Re: Cheddar Fly-in 2019 8th to 22nd July

The Chedder fly in is really something special ! unfortunately I was unable to attend this year, spoke to Ron at Cosford and expressed my appreciation for him running the event ! For those that have not been, the site is on top of the famous Chedder Gorge with a NOTAM of 1,500 feet above ground leve...

Re: Setting up a twin

If both red wires are left in place then the voltage regulators in the esc's will fight against each other and get confused.
Do not extend the battery wires on the esc, extend the wires to the motor if needed.

Re: new registration rebellion

Question 1. Do you fly a multi rotor drone Yes / No

If you answered No to question 1. then you have finished the test.

Re: new registration rebellion

Would I be correct in guessing that the online test will only be on air law such as CAP numbers just in case someone has added a clause or comma during the previous year ?

Are you using the rotating shaft as a screw or to operate cams ?

Re: Which battery type

As for 2 or 3 cells, that depends on the prop size you want to use, 2 cells for bigger props, 3 cells for smaller ones. That might seem backwards as you may be thinking that you would use a bigger battery to swing a bigger prop, the reason for small battery - big prop is the current involved and to ...

Re: Which battery type

Lion does not have the current capability that Lipo's do, I suggest watching https://www.youtube.com/watch?v=UB8fas6zBSE for a comparison between them.

Re: Printed Circuit Boards

I should have added that using a PCB and plugging in is better vibration wise than soldering wires that can crack off !

Please excuse the double post but putting it under "Electric Stuff" may have been the wrong place. I used to make my own by printing the artwork, transferring them onto the actual board with ultraviolet light and then etching them in ferric chloride. Now I use JLCPCB, yes they are in China...

I used to make my own by printing the artwork, transferring them onto the actual board with ultraviolet light and then etching them in ferric chloride.

Re: new registration rebellion

Maybe I am missing something, what is the actual use for registration other than for the government to show to show that they are "doing something" about quadcopter drones ? Can we expect knocks on the door by the police to ask if you were flying it at Gatwick :( What I do recall is at the...

It would not surprise me to see a new clause appear in the insurance saying that we must register for it to be valid :(
