Need Prop Advice.

[Rookieboater]

I have a new Mean Machine Cat with the Dynamite 3835 1500kv 6 pole motor. Will be running 2-2s graphene 5000 70C-140C batteries.

Need a couple props as starting points.

Thanks in advance.

What are your speed and run time expectations? An m445 will give speeds in the low 30s and pretty decent run time if the boat is trimmed out well, but an x545 or x645 will give better speed. Watch for heat.

I want to go as fast as possible for 2 1/2 minutes. Will be using the Seaking 180 speed control

I was turning a 45MM with some reducing,, on my mean machine, with a 4074/2000 kv on 5S 45mm sounds big to me for a 2s set up I would start at 40 mm 2 blade

Chris, he's running 4S using two 2S packs. That motor has a very low Kv for 2S. My club runs a 2S Sport Hydro class with 4500 Kv motors and the m445 prop, speeds in the mid-40s and one mile heats are easy.

But I digress. The OP can run a bigger prop than 45mm, that's a torquey motor. A lot depends on how the MM is trimmed, but an x447 or even an x648 might be okay for 2 minutes.
