Foil Drives patent application for the Gen2 was filed in Feb 2023 with a launch in October 2023. (WIPO - Search International and National Patent Collections).
Foil Drive claims the priority date for Gen2 was 25 Feb 2022, but that seems a bit odd considering their assist plus only launched on 14 Feb 2022.

Pwrfoil clearly built the first under board pod and also had it for sale in 2019:

Then there are open source systems that pre-date foil drives claims:

Foil Drive Assist, DIY - #119 by ptone?

I wonder, given the compact size of the controller and FoilDrive’s penchant for Maytech devices, if this is the model they use?

I think for Gen1 they used FSESC_6.7_PRO

Pretty sure its what they are using.

The 6.6 looks like a better fit and already includes the XT90.

They are indeed using that one. Interesting that they picked a 60A max controller…

How do you tell users that you have a low-power controller that is overheating?
Here’s how: we give you a free 10-second boost.

Whats more amazing is how they convince their users to buy into the obvious engineering faults…

That picture is a 6.7. Its written on the board.
FD uses the 6.7 pro v2.0. Its a 70A and the FD units top out at 1800w.
