The Jefftron Leviathan Optical is just absolutely incredible.
TLDR: It's incredible, and far better than the gate titan. Video attached to this review is on the Jefftron, 36k warhead brushless with a 14:1 DSG on 11.1v.
I've sadly been running a GATE titan for over 3 years now and it was always plagued with issues, for example:
1. With a GATE Titan, ROF control is literally useless, it makes your gun sound like a crappy rental with its PWM control, and delay mode for simulated semi spam doesn't work on the gate with brushless motors (so whats the point?)
On the Jefftron, its incredible snappy. It's delay feedback only, so you get easy, snappy sounding ROF control.
2. Bluetooth out of the box
On a GATE titan you're forced to fork out another $70 USD to use the GATE app on your phone. On this, it's already integrated. App is way better too. No need to enter "No shoot" configuration mode to adjust simple settings either, just open your phone and change a setting on the fly and its instantly sent to your gun.
3. Much better cycle detection
The gate uses a strange teeth/break system to detect a cycle, which is unreliable at consistency. The leviathan detects the cut off lever gear cams (which is on every gearset) which i've found to be much more reliable, and much more resistant to grease (which was a major issue on the gate)
Strangely enough, the snappiness of semi increased significantly with the jefftron over the gate. I don't know if theres some slow amp ramping feature on the gate, but I noticed a significant increase in responsiveness with the jefftron immediately when I switched over. I'm running 20% precock with a 14:1 DSG + 20k brushless and am getting 8 millisecond precock release response. It feels like HPA. The amount of compliments i've gotten on it already within the first few days of fielding it is pretty insane too.
My favorite feature of this mosfet is the RFTS (Real Feel Trigger System). It integrates an uptake and release feel, which feels like a real firearm and significantly increases the pleasure of using the replica. Somehow it allows me to spam the trigger faster aswell, likely due to the very clear trigger point.
Only negative was the included screw did not fit my retro arms gearbox and I had to move the gate installation screw + rubber washer over to the leviathan. I DID love the wire retainer clips though, really reduces the chance of snagging a wire.
5/5 it's the only mosfet i'd ever buy again. If you're starting a new build, check out the retro arms gearbox + leviathan mosfet bundle deal on Brill, it's a pretty incredible value.
