Hi,

So I have a large 1,3m long mono im converting to direct drive, it was a geared belt drive...

I really would like to not drill the hull if I can get away with it but...

Would a 1521 1Y on 4s driving a 30 (maybe 35mm) jet unit require cooling?

Which ESC should I go for? I have the as26's but they don't work very well with 4 pole hence my purchase of Lehner 2250's for my other boat and these are spare...



I was thinking about longer run times using 10,000mah packs / side... maybe cooling would be needed?
