Re: Massacre - FW

I would recommend a ground clearance of more than 8mm, with tank steer robots the wheels wear with every turn, they is no point in having a low ground clearance, wedges are running against the floor so your never going to stop them getting under you

I would recommend a 20mm ground Clearence, and putting grease on you wheels, it improves traction :P and if you want more power use alkali AA battery's, there the best! :P

Re: Massacre - FW

Hey, I just want to make sure I'm not violating any rules with this.
Is it okay to use 45a anderson powerpole connectors on my drive motors if i am using a lipo, would i get failed on tech check for doing so?
The main battery connectors are deans btw.
thank you.

Re: Massacre - FW

Use whatever connectors you fancy

Thank you.

Re: Massacre - FW

I may have put the scare into Haz because the rules state that batteries require sufficient connectors for their type/power. Someone stated to me that Andersons were not sufficient for lipo use (said person uses lipo's a lot plus he tech checks).

Re: Massacre - FW

We have a deans on each cable of our LiPo, so we have double whatever the rated current for a deans is (50-60a?). I assume this is acceptable? I didn't feel confident running the 4mm bullet connector it came with, for a start it had been split (previously used for use in series) and I couldn't see that taking the strain as nicely as two deans, really.

Re: Massacre - FW

It shouldn't be an issue unless you are running a high powered brushless motor that will be running the lipo to it's limits.

Re: Massacre - FW

Thanks for the responses. I'll stick with how it is and stick up a photo or video once it is all finished just to see if its all okay and there isn't any glaring flaws that will get me disqualified.

On another note, I need to be a bit stupid for a while. I need some help wiring up the weapon. I have a turnigy rc switch and two 70a 5 pin relays (one for each motor) and... yeah. Haven't a bloody clue what to do. I've had a look around and nothing was desperately obvious. Can anyone help me out? I'm so sorry if this has a very obvious answer.

Thank you.

Re: Massacre - FW

Still in need of some help. Feeling rather foolish.

Re: Massacre - FW



Follow the diagram making load the relay coils. Put coils in series if switching voltage > 1/2 battery voltage or in parallel if switching voltage < 1/2 battery voltage.

Either hook up the motors and contacts on a separate battery or put them in parallel with the coils to use the same battery as them.

Re: Massacre - FW

Thank you, greatly appreciated.

It's now slightly more robot than it was previously. I'm pretty proud that I got something this far, albeit with massive design flaws.


Need to get the wiring finished and attach the wedges and wheel guards.
