Battlebot 150g Fairy N20 Hammer/flipper

thingiverse

This is a simple and relatively cheap UK Antweight /American fairyweight battlebot. I had built this to be a loaner bot that I could give out without having to send my more expensive transmitter with the bot for them to practice with since it includes a basic 3 channel receiver and duel stick transmitter as part of the build. Parts list and build notes are included as part of the download. This is a N20 motor Hammer bot but also has a small flipper arm option. For the hammer you want around a 300-400 rpm n20 to get decent strike speed, while for the flipper you probably would be better off with a sub 100 rpm motor. Total cost came out to about $40 for me but could be slightly more if you lack some of the tools that I already had or possibly less if you find better deals on the parts. It should be noted that the esc/transmitter board used in this build needs to be cut down slightly to fit, it can be done simply with a pair of scissors just be sure not to cut through a solder line. please feel free to reach out if you have any questions. see it in action here https://youtu.be/XOBTjffyeKU?t=869
