ACETECH AceMOS Basic Mosfet Unit (Model: Rear Wired)

"I meant to say cutoff levers each time I said ARL in my previous review. Dumb mistake on my part. These things are awesome tho and wish they were in stock.

"I've written a review of this already but I just wanted to post a bit more info.
I've installed most of these mosfets into CYMAs, and these things don't seem to cooperate too well with the CYMA arl. I also installed one into an old KWA 2GX AEG and it suffered the same issue then too. You'll get full auto fire on semi unless u pull the trigger back stupid fast. I'm positive this has to do with the stock CYMA and KWA 2GX anti reversal latches. They do seem to work well with Lonex and G&G ARLs from my testing. They also worked in the 2 A&Ks I've installed them into. This is my long winded way of saying that these things are a bit picky with working correctly with certain ARLs. They're still awesome for the price though. Definitely recommend them.

"I've bought several of these so far. I've installed 2 in VFCs and 1 in an A&K. Fairly easy install. Only tricky part is getting the negative wire to go over the signal and positive wire while putting them into the wiring channels in the gearbox shell. Does come with a basic instruction manual and spare 30amp fuse. Very awesome basic drop-in mosfet.

"I bought one of these a little while ago to put into one of my beater Scars, I wasn't expecting much due to the price but I was actually fairly surprised. The packaging was very nice. it comes with a very detailed guide with multiple languages, it also includes an extra fuse and heat shrink which was surprising that they would include the heat shrink as well. The mosfet isn't anything special it looks to be made with quality and works quite well for what it is, it does increase trigger response not to mention its prewired and uses deans connections. Overall a good product

"I bought this for my A&k featherweight m249 and it works great! It keeps my high speed neodymium motor from overheating at fast pace pickup games. Also keeps my 7.4v lithium ion from any over-discharging. I did also drop in 13:1 gears and made sure to do the best shimming I could which helps. This is also in a DMR style build with a high torque motor and an m160 spring. It performs very well and has a very snappy response! If you wish to have a “hair trigger” I recommend modifying the trolly trigger spring to be tighter and either shimming your current trigger with an old credit card and super glue. Or spend a little extra for an adjustable trigger to get the same effect. I noticed this works without any issues in the VFC gearbox as well as any Gen 2 Lancer gearbox. The cutoff lever in both of those gearboxes work without issue and no need to modify. Take with a grain of salt, I might have just been lucky both times. Definitely a great starter MOSFET if you are early into Tech work. As others have mentioned it is a little difficult getting the wires to sit flush under the trigger. Also my only bad encounter was on a replica I built for a friend. While putting the wires into the buffer tube it caught onto the buffer tube nut and the black wire was immediately damaged with the copper inside completely splitting. This was all user error but a warning to be cautious while putting together your replica. It was a very easy fix though after cutting the bad wire out and soldering in some spare wire from the old trigger unit that was removed. No issues since!
