OK......so with a 120 amp ESC and the Leopard 4074 how do we think theses are gonna work? I tried the cheap glass filled plastic just to figure out what works.

52mm Diameter, Pitch 1.4x52=72.8mm or 2.87" 3 blade

47mm Diameter, Pitch 1.4x47=65.8mm or 2.59" 2 blade

Also they say 20-25k rpm. Is it unsafe to turn theses higher than that?
Sorry to ask what so many have already asked but this thing looks HUGE compared to stock and I want to go FAST without burning her down! Thanks for the advice!!!

I would not run the 52mm prop without knowing the voltage and the Kv of the motor - telling us just the size of the motor is not helpful at all. If you exceed 25,000 rpm the plastic props may throw a blade.

It's a 2000 kv max 25 volts. Ran it today. CRAZY!!!! Went like a bat outta hell!!!! But the t120 esc thermalled after about 5 minutes on 4s. It read about 170 degress. The motor was 110 the batteries were were atound 100 also. seems like i Just need a bigger esc
