  • Right just to keep people posted and so i have a record to keep track of i'm going to post up a few details of all my robot projects that will be happening over the rest of the year.

    So here it goes..

    Hatchet - Buying the old girl back some time soon and making a few more modifications, namely a new scooter motor, upgrade from a 4 to 5s Lipo and possibly a reduction change on the axe. Going to be using it as my running feather for events until i get around to building Hatchet 2 at which point Hatchet will become a Whiteboard machine.

    Hatchet 2 - Putting a lot of thought and design time into this to make sure it's as good as can be, will be built towards the end of the year/beginning of next year. Changing just about everything to make it stronger, more reliable and crucially more powerful, I won't give away too much as the specs have changed from when i last posted about it but i assure you all it will be a MUCH better machine.

    Lynx - My beetle i'll be bringing to Brize Norton, basically a Hazard style overhead spinner with a stupidly big blade powered by an even more stupid Brushless at a stupidly over the top 4s. Will be starting this early next month so keep your eyes peeled for updates!.

    Buzz - Antweight bar spinner, basically a teeny tiny buzzbar with a 2mm stainless steel blade. Hopefully i can get it together for AWS but building it and the beetle side by side might be a bit ambitious in the time frame. If not there are always more Ant events and if it comes down to it i would choose to focus on the Beetle.

    Wraith - Something a bit different this one, after finding the motor/gearbox combo i posted a couple of days ago on my doorstep i decided i really wanted to use it in something. Well after thinking about it i've come up with Wraith, basically i'm going for a Featherweight version of IG-88 from Robot wars. The robot itself will be pretty old school, i'll be using drill motors, servo switch esc's for the drive and a relay for the weapon, the chassis will be a mix of Hdpe, Nylon and Aluminium and the bar will be a whacking great lump of stainless ( 250mm long, roughly 25mm thick!). For testing purposes it will be run on 5s but for full combat fights i'll run it at 6s and see how that works, won't be all that damaging or high tech but i quite like the idea of making a simple, cheap spinner just to show that it can be done.

    • I look forward to seeing what you do with the new hatchet and seeing how the beetle performs, from what you said on earlier posts it should be pretty nasty :P

      • Cheers Andy, Hatchet 2 *should* be a massive improvement ( not hard ) over the first, what i will say is that the axe will be roughly the same size/weight but will be run on a 350w motor (up from 300) a bigger reduction and at 6s.

        • Just a quick question, i'll be using a relay to control the weapon of Wraith (IG 88 style spinner) i'm a little bit stuck on how to wire it though. I've got one of those Turnigy on/off switch things and an 80a automotive relay, any help would be fantastic.

          • I haven't used that switch myself, but there is a wiring diagram here: http://www.hobbyking.com/hobbyking/s...X370526X29.jpg. Hope that helps...

            • Cheers Nick although it's more about how to wire the switch to the relay and the relay to the motor and so on

              • Also found a huge steel disc that looks like it could be good for an interchangeable weapon, 6mm steel, 230mm diameter and around 2kg. Wouldn't cause any huge damage and i wouldn't bother using it against other spinners but still could be fun. Couldn't resist stacking a load of bits onto the old base from Hatchet, the whole thing would need to be a lot bigger but it still looks good all together.

                • One wiring diagram coming up...

                  • Facking sick mate, I love it. Shoot us a message, I might have some spinner stuff you could be interested in.

                    • Awesome thanks Nick

                      Harry i'll drop you a pm

                      • OK, this should explain most of the wiring:



                        The relay should have symbols similar to what I drew on it; the important thing is to not use the NC (normally closed) side of the relay. Your relay might be different to the most common one I drew, so let me know if anything isn't 100% clear.

                        • I would not use a relay to fire the weapon. I would go with an ESC. I was using 50V, 80A Solid state relays in Conker 1 & 2. I lost one every fight to it either burning out or getting suck on. Buy a 3rd TZ85A and use that on the motor. That's my advice.

                          • I think you'd be fine with a relay tbh. If you're running a lower voltage, say 6s max. Relays handle other brushed spinners like old Inertia XL's and Scissorhands (although that has now gone over to a couple of botbitz I think)

                            • The plan is to run it at 6s max so ill try the relays and see what happens, if they prove more hassle than their worth then I'll upgrade to something else. Tbh the only reason I'm using the relay is because I had a couple lying around.
