I did something similar with The Honey Badger 2.2 where there was a sheet of Aluminium over a layer of HDPE. Had I bolted it down properly, it would probably still be with me but it seemed to hold up quite nicely against non-spinners.

Having a bit of bother with the servo controlled linear - I took this from the Barróg thread
[QUOTE=RogueTwoRobots;468452]On point number 2, the easiest way would just be to use a servo to turn on a couple of microswitches, one for each direction. It allows you to control forward and back from one radio channel and the stock actuator motor will have a low enough current draw to not require any additional relays etc. Here's a setup in its simplest form; I usually tend to just hot glue the switches onto the sides of the servo and wrap a cable tie around them, but you may prefer a more robust/maintainable/aesthetically pleasing alternative :)

I assume I wired it wrong. But not sure how I identify the right terminals.

My expectation was without either microswitch engaged it would be off. With one or the other polarity would be reversed.
I possibly toasted them in the process of getting it wrong.
The switch is a Z-15GW-B
The pin nearest the rocker is 1 - COM
Centre is 3 - NO
Nearest switch extended arm 2 - NC
Advice appreciated as my electrical know how is poor at best.
I think if you connect on each switch:
pin 1 (COM) to the motor
pin 3 (NO) to batt+
pin2 (NC) to batt-
I don't think you will have blown them up :) as long as you keep the motor connected across the 2 common pins, you should be ok.
Let me know if this works, or if you want me to draw a circuit diagram.

you're a genius! that works thanks very much
Thanks to the help of Paul I got the linear control working. At least this mock up, which powered a small 12V motor. The idea is to make a sandwich with some polycarbonate as the bread and the microswitches as the filling. Conveniently the mini servo I am using is just the right height to align with the arms.

I need some long 4mm bolts and some longer 1.5mm bolts, and in the final version the polycarbonate will shield the arms too. (Pictures updated with bolts fitted)
Got a few deliveries this week.
Bolts, nuts, titanium plate, polycarbonate
I am going to make the top mostly from polycarbonate as it's light, also it's cheap to replace so no big deal if destroyed after each event. I'll add reinforcement behind.
Did a little more work on the electrical system. Configured the buck voltage reducer to put 18V to the lineac.
Added a 'live' light, a 100A fuse for lipo and a kill switch/jumper
I am making a polycarbonate lid for the bucky and adding a fan to be sure it can handle max load.
Here's a video of my lineac controller working

Its looking really good :) I am excited to see it all together.
Thanks very much.
I added some titanium plate to the front instead of that bit cardboard ;). It weights in at 13.02kg so once the ramp is fitted it's going to be a bit over but lots of opportunities to lower weight.
Having some electrical issues. Got it all wired up, motors spinning, lineac running, but something is not right.
