We may need a new definition for micro:

[old guy]

I have a mini cat hydro. It has a castle creations 4600kv motor and is set up for
4s. the motor is almost as big as the boat lol. carbon props just blow up after a couple runs so when the water is soft again I will try a metal one. how fast, to fast but it turns. when you pin it it will jump out of the water and land about 15 feet away. I will try to find the youtube fid

Could you share a link and specs for the Turnigy lipo? Thanks! I'm always interested to see what lipos others have been using in their small models.

with a 4600kv motor, it surely isnt a 4s boat!

[old guy]

not sure if this will work. this was the vid he had on ebay were I got it from. this video you will see it go, I put a little bigger prop on it and on glass water it was way faster

Something hear does'nt add up;-)

Not wise but doable.
I have a 22" tub rigger that has a 7S-5070kv can that I once fed with 3S to the 432 prop for low to mid 40krpm at the prop

What is being suggested above is good for low 50krpm at the prop and there is no surprise that he blows carbons at those rpm. I blow them at 40odd krpm. Given they are suggested for up to 25krpm then we are all having fun.

Some guys use high rpm for speed and some go for prop dia. I like rpm. It sounds nice.

If the you-tube vid will ever load then I may get to see his boat doing its thing, for now I believe him.

I like RPM as well Simon, actually, I like a happy medium between the high rpm and a decent size prop... I am still experimenting with it to find the happy medium.

This is about to go off the original topic and may need a new thread. Non GPS tuning methods There ya go Jan, you can start that one !!
I do a lot of my tuning by eye, ear and finger, ( cooling )
If it sounds like it is screaming, I smile and feed in more prop and watch.

I was merely agreeing w/ Simon but I can see where how can stray, sorry everyone.. back to topic...
