The HHFF is an Erector Set for adults. It can be endlessly configured to meet your direct drive needs. The systems uses standard 15mm traded rods and standard D-Rod. You can get the D-Rod from Servocity plus a lot of other cool stuff. The mounting plate will attach to either side of the gear box allow you to orient the drive shaft in any direction. We offer two different size swing-away arms and many different size drive wheels, with which you can gear up or down.
Special thanks to my brother Hayden and his band Skirts for the music.
