I'm Thinking Of Building A Feather, And Need Some Advice

You would have to invest in a mixer in order to give you full control on one stick unless you spend a few more bucks on the TX and get one with built in mixing

Hey Kevin. You dont necessarily have to have a completely flush wedge to be able to get under other robots. I went for a similar idea to yours on my first bot and made the wedge completely flat against the arena floor. After I had seen the other competitors I realised that the majority of them actually have a fair bit of ground clearance so most wedges could get under them even if they dont graze the floor. :) And with arena surfaces sometimes being uneven, it might be best not to have a super flat edge.

If you have a flat piece of metal coming out from your wedge so that that can go under your opponents then you will be more effective. What I am clumsily trying to say is the front can be like the front of Bigger Brothers flipper.

I plan to use an electric window actuator from a car as the flipper. How fast would it work with a 12kg robot on top of it?

Slow. It would be a lifter rather than a flipper. If its not gas or spring, I cant see anything being a flipper.

Not even if I over-juice the electric actuator?

A CO2 flipper pops in a fraction of a second. An electric motor system will never manage that. If it did, no one would use CO2 for all the trouble it is.

Crank back a spring with an electric actuator and that is a different matter.

Storm II manages about 30ms for full stroke from down to up, and even thats not true flipper territory.
