[Kos-Mos]

I have no first hand experience with the ASCU, but I did install some FET units on front-wired guns.

I used a 20ga wire with a simple pin/hole connection just where the battery wires have a connector. It works great and since it is just a "data" connection, you don't need an extremely efficient connection.

I really like the idea of the trigger replacement block, but I find that their software is lacking a bit. It would be easy to implement a motor brake without any extra hardware. An other solution would have been to use the cut-off lever to trigger an optical switch. Parts cost would be under 5c and I guess that the software implementation would be very simple.

The other thing I don't like is the size of the unit vs the features. It is really big for a simple MOSFET unit with very basic control features. I guess that if they didn't add motor break, they are not using a H-bridge setup. That means that only 1 FET would be required and it does not explain the size of the thing.

They should sell the trigger module by itself to let people use it with any MOSFET module (either SW or basic home-made). Might just build a trigger module with some board I have...

*edit*
Apparently they have implemented active braking since the last time I checked, and the semi-cut-off works properly. It is a lot more interesting now, but at 100$/unit, I still find it quite steep.
