Stick packs will work if the kit still has the right battery strap holder pieces. You'll have to mount your esc on the top of the back battery holder piece.

Will they fit in a mid motor setup or do I need to find some shortys?

I plan to run shortys or something else but I'm just wanting to get through the weekend until I figure out what I want.
IMO, I wouldn't bother with the stick and I'd wait for a shorty. I'd hate for you to make you decision based on using a stick pack when that probably isn't in the best interest of the car.

Holy moly! So I picked up this kit will all the optional parts for the Zack Rogers setup because a friend of mine is running this car with the rogers setup and the car is amazing. As I have found building the car is a major pain in the ass, worst build I have ever done worse than any old Durango kit by a mile lol! The fit and finish of everything is good, but each step requires parts form various bags which are not called out in the instructions, not to mention the pounds of flashing that mush be trimmed off all the parts.... I didnt realize this kit was gonna be suck a PITA, oh well, at least it will drive nice. Rant over....

The build is a pita, but it's a one time thing. After that, nothing but a smooth drivin buggy.

I felt your pain with the RB6. Friggen parts were everywhere! It was like emptying every bag into one big pile. I also loved the "Engrish" in the instruction manual too.

I thought the ZX6 build went a lot better than the RB6.

Got the car today and it's super nice. I looked at the assembly manual and it shows a stick pack with mid motor but nothing goes between the battery and motor so the battery hits the motor. I'm going to leave it setup for a shorty pack and grab a couple before the race. My 10 year old is racing it in beginner class so I'm not super concerned about dialing in the setup until I have a go at 2wd mod. class.

What are you guys doing with the ZR setup to keep the battery from hitting the motor?
