Probably a topic on that somewhere in the forum, but still needing to get the RC51 to run cooler in the TX heat. Heard you can get bigger fans or motors and fans that would help. Anyone tried this mod. and where did you get your aftermarkets at?
Not knocking you, but you really need to try the search. We've discussed this to death over the last couple years.
Try words like *spal mod* (that's probably the most popular), cooling mod, overheating, running too hot, etc.
