"Absolute garbage. I failed to look at the reviews and comments before buying this, only the price tag. I have spent hours trying dozens of possibilities to make this thing work correctly in my gearbox to no avail. As soon as the battery is plugged in, the motor fires in full auto and it's obviously due to a defect in the mosfet. don't waste your money, buy another brand. "Installed on a stock Dboys Scar-L with a 7.4V lipo. Plugged it in and the gun went full auto the second the battery was plugged in! Tested unit outside of gun, made sure trigger contacts were not touching... plugged in battery and went full power to motor. Fuse blew. Removed heat shrink and mosfets tested bad with multimeter. Waste of time and money. "The value of these things is off the chart. A switch alone will run $10, and with this package you get a very nice MOSFET AND a brand new switch. All for a whoping $13 bucks. Look at the price of any other FET and it's double, triple or quadruple.. and they dont come with a brand new switch along with it. You can get MOSFETs outside Evike at places that like rhyme with "c-ray" for around $18-$25 bucks, but they are privately manufactured and they dont come with switches.
These Matrix MOSFETs come with the "low resistance" silver plated wiring that in theory sounds great, but in actuality have no noticeable affect on performance. Theyre really more of a pain in the @ss than anything because theyre so stiff and hard to work around through the gear box and onto the motor contacts in the pistol grip. As a matter of fact, what Ive done on two of these now is desolder the stiff wiring and rewire the thing with 16awg silicone wiring. The kind of wire that has the very soft pliable silicone insulation that comes stock in most AEGs. I rewire with 16awg silicone wire, 2.8mm spade terminals, deans connectors, 2mm, 3mm, 5mm and 13mm heat shrink (13mm for the MOSFET unit itself). I do it up right. make all the wires the perfect length for the particular gun its going in. Make sure theres enough length to access the fuse out through the end of the buffer tube on a crane stock or the full stock of an M16. Wish I could post pictures of my re-wired rigs with these Matrix FETs. I do a proffesional job on these things.
Now I want to address two suposed cons that two reviewers here mentioned. Ok, one guy says the spade terminals for the motor contacts broke when he bent them down (like you have to do to get them into the pistol grip). I guess that could happen if youre careless. Before I decided to rewire mine completely, I originally used the stiff wiring that came with the FET and had to bend the motor contacts down also because they do come straight (unbent) out of the package. I bent mine slowly and carefully and they did not break and worked fine. Another reviewer says that this MOSFET eliminated his semi-auto fire. Thats impossible. These things dont work like that. Trust me. What happened with that guy is that either the spring that connects his cut-off lever to his selector plate came off when he put his mechbox back into the lower receiver (which will of course make semi-auto not work), OR, sometimes when you put your mechbox back into the lower reciever and tap the take down pins back in it squeezes the mechbox against the lower reciever on the selector plate side, causing the selector plate to get pinned against the side of the lower receiver and get stuck and not operate properly.
Now on to the benefits of a MOSFET. How these things work is that they re-route the juice AROUND the switch directly to the motor itself. There are two 24 gauge signal wires that connect to the switch. The FET detects a closed or open switch through these two signal wires and when the switch gets closed the FET acts like a gate and closes off juice to the switch directing it straight to the motor. Pow. Full on power straight to the motor. MUCH improved trigger response and most importantly, no burnt up switch contacts from using kick @ss LiPO batteries. One reviewer said that the thin 24 gauge wires that connect to the switch itself got really hot. Haha! Can't happen. The 24 gauge wire is for signal only, the full power of the battery does not even pass through these wires.
Get this MOSFET/switch combo. Theres no downside. Only benefit. Especialy is youre using a LiPO battery. And if youre a mechbox geek and really into it like me, desolder those stiff wires and re-wire it with 16awg silicone wire and deans connectors. All materials available at that place that rhymes with "c-ray". Be carefull rewiring a battery over to a deans connector. Never let the positive and negative wires make contact. And don't cut both the wires off the tamiya connector at the same time shorting out the battery. It will kill your expensive LiPO battery. Cut one wire at a time and tape it off then cut the other wire. Keep the contacts taped off from each other when soldering also so that the soldering iron doesn't touch both sides together shorting the battery out.
PS: Make sure that the wires going through the bottom of the box over to the switch are laying as flat as possible or the pinion gear on your motor will get hooked on them. If that happens youre screwed. You will not be able to remove the motor from the mechbox and will have to rip the wires out to get your motor out. After you put your mechbox back together if you look perpendicular into the bottom hole of the mechbox where the pinion gear goes in, you should not be able to see the wires, or just barely be able to see the wires. Otherwise your pinon gear will get hooked on them. Read More Reviews Write a Review
