All-in-One kit with switch: four motors of Kit #8 with a single switch control

Discount: 10-24 - 5%; 25-49 - 7.5%; 50-99 - 10%; 100+ - 12%

Designed and made in the USAAll-in-One kit with the switch: includes all parts required for assembly of 4 brushless motors where you can quickly switch between them.

This is a perfect kit if you want to experiment with different configurations and learn how all these motors work. It is essentially Kit #8 where with a simple turn of the knob you can switch between four different motors:

• R – Regular reed switch motor
• T – Reed switch motor with the transistor
• H – Hall Effect motor
• O – Motor with optical control

This motor uses standard AA size batteries (not supplied). Included jumper wire allows to experiment with different voltages.

Soldering iron required for assembly; you may add an inexpensive one with some solder here.

    I’m ordering 2 more of kit #9 today plus the solar panel since we got kit #10 (also #9) before and have a few components the next child will be able to reuse. (multimeter, color wheel, something more I can’t remember at the moment) All of kit #9 is needed for each student because they need the experience building their own. This is the best hands-on option I’ve found for learning these concepts.
