Works as a MOSFET, but the design is not well thought out at all, the signal wires are connected at the wrong end so your tiny white connector gets pulled and breaks easily, thus requiring the signal wires to be soldered permanently, which makes any gearbox work a tiring effort having to try to run your mosfet back through the stock tube. The mosfet is quite big and doesn't come with any heat shrink for covering it up either, save your pennies a bit longer and get the GATE MOSFETs.
