They are good if you get a working unit. I have bought faulty ones. Bad luck for anyone who tries to install a faulty unit. This voids warranty. Warranty is covered if you get WAT’s to i stall for you. A clause written in red. Recommend: get it checked before leaving the store.
No guides showing how to install the mosfet, replaced the XYLARP9 mosfet with this one with only 5 attempts. Easy to program fire select, not so easy to program prefeeding and/or it doesn’t work! Continues to preload gels randomly (could be poor soldering maybe). Overall fixed the ARP and good for the price. Video guides for installation are in other languages so good luck!
Fast and very responsive
I'm very happy with my purchase, never had any problems with these Mosfets. I run them in most of my blaster builds
= Cracked gear box of Wells Metal CQB M4 + LDX expert V2 gear housing + Bigrrr Mosfet =
This is my story about my “gearbox cracked Wells M4” and this very reliable and reasonably priced easy installation electric trigger mosfet system.
After I had swap the gear housing with LDX Expert, I realised not often but sometimes this gun skip the gelball shooting in full auto with 11v battery (no issues with 7.4v but.) And I realised sector gear was slipped slightly because of gear stopper was malfunctioning sometimes with 11v speed…
It had same tendency with original zinc housing but probably gears can turn even quicker with LDX expert housing (may be it’s caused by less friction from my good gear shaft shims and LT2 gear grease instead of sticky and heavier factory silicon grease…)
The semi auto stopper obviously has the timing issues now.
So I had decided to put this from WAT.
The steel sector gear came with Wells metal M4 had a exact hole to be installed the magnet for the position sensor. (What you have to do is just a little bit of “touching” inside of the hole you wish to install the magnet on the sector gear with a drill’s tip to smoothing…
Installation of Bigrrr mosfet is so simple and the one from WAT already connected with gen8 style magazine terminal connectors (many of this kits available on the chinese shops on the webs are for Airsoft and has no mag terminal cables connected…).
As the result, my gun has auto preloading gelball function and various programmed semi-auto functions. :)
Thank you WAT :)
