I use novak gtb brushless esc with novak 3.5R sintered rotor.
Number of use: only 5 races including today, with very little practice time.
My car is tamiya 415msx using FDR 11.52 ( I race in tropical climate, so 11.52 fdr is already the limit if I want to keep the esc and motor below 80C / 175F after 5 minute run ).
Here is the problem :
On race #4, I bought 3 set of Hi Speed Energy Lipo 4000Mah 35C
It was awesome to feel lipo power and brushless. The car went balistic during the race. I was a happy man on race #4.
A month later, On race #5, I still use the same car, fdr, lipo, motor, esc, etc. The problem become noticeable during final 1,2,3. How come my car lost the punch and acceleration ? ..... I feel the punch and acceleration were not the same compare to last month race ........ and worst, my friends also told me " why your car is slow today ? "
So what's happen in here ?
I'm thinking to replace the rotor as my first try
2nd question, adding one more power capacitor pcb board like the one already installed in gtb, is this beneficial ? or over dosage ?
