Fitted Lf3 with a new flipper system but it is 1.5kg heavier than the old system so have lightened the
chassis today and wired it up. Shall put it together tomorrow and see how much armour i cant put
back on and then test the flipper if theres enough time.

Thats pretty neat, how are you expecting it to act compared to the CO2 system?

Sadly, I've had to withdraw doorstop as some parts won't arrive in time (even though I was promised they would!). best of luck to everyone!

[PJ-27]

Is that a solenoid?

That's a shame
What parts do you need? I'm sure someone who will be there will have suitable stuff.

Custom made 5mm steel wedge and two machined HDPE wheels

Hopefully will make it to burgess hill!

anyone reading lower than 8.3kg ??

8kg exactly according to my scales. Oh the joys of wooden robots.

Okay, not many of us will have them lying around in our spares box :P

But looking at the last picture of Doorstop that you posted, could you not just put some tyre tread round your wheels and some more HDPE at the front (on the vertical bulkhead, rather than in the shape of a wedge) to absorb the majority of impacts?

Im sure you could get doorstop working, maybe not quite in the way you intended but should be fine

Yes its a 26KW solenoid, in theory it wont be as good as the co2 system but havent tested it yet
with the flipper arm on and dont know how long it will last.

A while back I was looking into Solenoid alternatives to CO2 but ran into problems with stroke length being too short and the fact that the solenoid loses power as the arm extends further.
What sort of Nm rating has it got? I found I needed something like 2000Nm to contend with a FP flipper system.
