Just spoke to dave on the phone who explained that I will need to experiment with the pot to find the resistor values. Im using 2.2k resistors at the moment and I do have some control so im thinking its just the wrong values. Hopefully it a common size otherwise it will be very costly. If anyone can offer any help, im using the MG996R servo boards.

If you have trouble obtaining the resistor values you need, let me know. I may be able to help :)

Ive changed my design now and was wondering how to bond polycarb to polycarb for the chassis? I've read the normal superglue will work but is this true?

Superglue will weaken polycarbonate over time, and is not really recommended.
Nuts & bolts or rivets are the best bet. Epoxy can be used, but the best way is to drill holes in the pieces to join so that the epoxy runs through the holes and forms something like a multi-rivet joint.
Polycarbonate more than about 2mm thick can be tapped and will hold a machine screw quite well. M2 screws work well if you have thick enough parts to screw into.

ok, epoxy it is!

What thickness do people go for when making 3d printed chassis/ armour? would 1mm be enough or does it have to be a little thicker?

cheers!

Depends on what its being used for. I know that 3mm will stop most if not all spinners, 1mm as a structural part is probably a bit thin. For example, the side armour on Baby Hell was mounted through a 1mm printed plate (part of the chassis), and it kept snapping off or breaking under spinner impacts. Changed to 3mm at the edges and its survived 2 spinner events with no issue.

Nearly complete! servo boards and lemon Rx work great (although you have to sub trim quite a bit to centralise them) and the 3d printing has turned out well. At 86g, got plenty of weight left for the 1mm polycarb lid and Ti scoop. any tips are welcome.

Cheers, Dan
