Gate X-AXR Alternative/Sources

The mosfet in the boy's Specna has shit itself and needs replacing. 

Are there any better three wire mosfets worth looking at, or should I just get another one? 

Tah muchly.

Yeh - the X-ASRs do that. Especially if you put a few more amps through them (i.e. an upgraded motor).

Don't bother with another one. They are shit. And the wiring setup differs from the Nano-ASR, Nano-HARD, WARFET etc so it's not plug'n'play.

I would go down the Perun Hybrid route personally, but a cheaper option would be to either fit a complete replacement switch/wiring set (non-mosfet - will work for years on a 7.4v LiPo), or fit a cheap simple dumb mosfet (like the nano-ASR) and at least you can easily upgrade to the likes of a WARFET later.

Maybe try the Perun AB++; it has three wires https://perunairsoft.pl/products/ab_plusplus/

Burst control, AB, precocking, ROF control etc.

Yup, it's very well featured for the price. You'll need to do a bit of soldering, but into every life some flux must flow.

It's the pricing that puts me off that one - another £15-20 gets you the excellent Perun Hybrid unit with the wiring already soldered. Should drop into a Specna GB with no fuss.

NanoASRs can be had for £20. Yes, you still have to solder, but the two signal wires is easier to deal with than two power wires plus a signal into the switch for cable routing. Obviously you don't get AB and precocking, but you do get the ability to hot-swap the unit later on if it dies, or you want to upgrade.

But again, for me, the Perun Hybrid is the way to go.

Edit: Looking at the wiring diagrams, you could bodge the AB++ onto the existing X-ASR wiring. Not sure I would want to do that personally but it looks like it could be done.

The question was about three wire mosfets.  I have replaced a three wired mosfet with the AB++ by connecting it to the existing cables; it is a simple soldering job.

Yeh - got it in the end, hence my edit.

Thanks for the advice - will take a look at the options.

The AXR didn't get anything through it that it shouldn't, but I think one of the wires came loose where they are soldered onto the PCB and shorted something out, as the plastic protection has started to come adrift too.
