Talon speed controller with power terminals connected. Leads are terminated using non-insulated spade crimps (McMaster p/n 8007K17) and then sleeved using 1/4" heat shrink tubing (McMaster p/n 7132K74 black, 7132K42 red). The black wire is 600V rated 10 AWG and the red wire is 300V rated 10 AWG, both PVC insulated UL 1569 30 strand 90 Celsius. The 300V wire is fine for FRC applications and save some space and weight compared to the thicker 600V.
Terminals were crimped using the Thomas & Betts tool shown.
All of the above can be used with Victor or Jaguar speed controllers also.

Very nicely done. Am I correct to say these terminals can be pushed on and off a loosened screw without the screw being removed? The terminals don't permanently spread wide do they?

Thanks!
You are correct, the terminals are designed to "snap fit" on a #6 stud. The speed controller connection screws are slightly smaller than that, so the terminals slide on/off easily when the screw is loosened, and they don't deform.

Re: pic: Talon connected
Could ring terminals be used or do the Talons possibly suffer from the same issue the tan Jaguars did with removal of the screws?

It looks like there's an important difference between a Talon and a Victor. Victors have the (-) power input connection at the corner; Talons have the (+) connection there.

lemiantIt would matter because with both on a robot we'd need a new strategy for verifying the correct polarity of our speed controllers. "Check to make sure black is on the corner", isn't going to work very well.

Bingo.

For those who've already ordered Talons, do they come with mounting screws and/or spacers for the optional fans? (This is important for teams in the middle of nowhere like mine. 
)

However, I don't think the mounting will be complicated. Two screws 6-32 x .625" should do it. No spacers needed.
The holes are about 1/4 inch deep. I put a 6-32 screw in one of them as far as it would go, and then counted 8.5 turns while taking it back out.

Yes, a victor fan will fit on a talon, and vice versa.

Re: pic: Talon connected
Would it be possible to tap the fans with a metric thread? Do the holes bottom out before the PCB? Would we introduce too much swarf?
Here there is an extremely limited selection of imperial, the only imperial hardware we use are from AM.
Alternatively is it possible to use something like the clips for the victor fans?
