Hello,

I will be running a Xray T4 with a Tekin RS PRO and Tekin Redline Gen 2 13,5 motor in a calss that allows timing and boost.

Temperature is during winter a bout 5 - 15 C (41 - 59 F) and in summer 28 - 38 C (82 - 100 F) and normally humidity is 60-80% here in Shanghai.

The longest heats we will run is 8 minutes in some races.

What sizes and placements for fans and heat sink will I need for this? Do I need the same both summer and winter?


Last time I was running touring was in the early 2000s with brushed systems and NiMh so I have some catching up to do on a few points, so thank you in advance for the help!!
