Sorry for reopening this old thread, but since I've been switching back from building tiny quadcopters back to robots, I realize that I'm not sure how you'd use a PPM receiver with a brushless motor weapon. For my robots, I've always just used a nice fat PWM receiver with pins for each channel. How ...

Is that a mini-version of the Fingertech weapon blade?

Does anyone know what screw to use on "the pink servo" (linked above at Hobbyking) for attaching the horn? I seem to have lost mine, and can't find the specs online.

We actually began buying stuff for our neighborhood battle box--based mostly on scrounged supplies. (We found a 1/4" sheet of polycarb that's 48x39 inches, and 80/20 channel that's in 16" lengths.) Given our scraps, we could build a 3'x4' or even 4'x4' arena, but the roof would only be 12&...

I'm about to start my first kinetic bot (after building a 1-pound wedge and a 150g flipper), and I'm trying to wrap my head about the weapon blade. Are people still using 2mm stainless steel (like I saw in an old post by Rory)? I have access to a waterjet that terrifies me, but I'd love to have an e...

Finally found a video of Swarf at Robogames--the 3-person rumble at the end. I finally made a polycarb linkage rather than a paper clip, and it was the first time the servo arm didn't detach. It also meant the titanium didn't go all the way flush, so I grabbed a bit of plastic and duct tape, and ext...

Made it with maybe ten minutes to spare, and the fix worked great--I had a ton of power in the flipper, no brownout issues at all. Again, thank you! Of course, the first match I forgot to bend over one side of the paper clip that was the linkage to the servo, so I couldn't self-right after the first...

Need to leave in about 45 minutes, plugging the soldering iron in now!

Cutting it a tiny bit close...

Thanks again.

Okay, so to be clear: I remove the red wire from the receiver, and instead wire it directly into a splice on the red wire from the LiPo? Leave the other two heading into the receiver as before? Do you just solder it directly in? I'm guessing I'll want to use this servo in other, better bits later on...

Help! Finalized the chassis, got everything in, but when practicing driving I realized that I have an electronics problem. When I actually try to lift anything, the receiver browns out. With no weight on it, it flaps up and down happily, but if there is any torque on the servo, it just dies. I'm usi...
