I've run an MF2 with a 13.5 and Orion 4800. I usually start with my stock +2 teeth for pinion. I've gone as much as +4 teeth, if I'm on a large open track.
Stock being = 19-21, depending on your setup.

What do you guys used to check your motor temps?

2) do I need to use the GTB's supplied capacitor with the 13.5 motor? You know, the beer keg of a cap. I would like to use the small cap that is included with the LRP worlds kit, mostly because it is 1/20th the size and 12th scales don't have a lot of landscaping area for electronics.

In 4 cell you definitely need to have the capacitor on the speedo. There's plenty of room for it. I'm thinking about adding a second cap to help keep the speed control temp down.
I can fit the speedo, transcap, and a receiver pack in a L4 style car.

You do have to gear up when switching to the sintered rotor. People run anywhere between 36 and 42 mm roll out.

I just started racing with the sintered rotor and I think I may be able to gear up as much as 3 teeth or more from the regular rotor. Been running the 13.5 since September with the regular rotor with no troubles. Except I finally burned up my LRP COMP.

Gear up.

Yes, you have to gear up with the sintered rotor because it has less RPM. We're going as high as 2.5 rollout in 12th (or higher) but you have to play with the gear to get the best laptimes. I'm only using motor and speedo temps as a safety thing. The lap times drive my gearing (normally around 2.35 in 12th on carpet).

Have found that with the Sintered Rotor, I can't gear up the TA05 far enough, can only go to a 25 pinion and was running a 21 with the bonded rotor, to get the speed back I'd need to be around a 29-30 pinion which won't fit!

@Nexus - change the 48dp standard spur in the car to the 64dp 105T spur that is available for the TA05. that will give you the gearing you want. hope it helps!

I saw a post on another forum (but then lost track of where I found it) that someone has already been able to purchase the 13.5 Pro motor (not the system with the ESC, just the motor). But a search online did not turn this up and any online vendors. Is the 13.5 Pro motor available for purchase or must one buy the sintered upgrade separate? Thanks!
