motor quistion

[lrm50]

Recently built a 33 delta force mono set up with 240 hydra 2 3s lipo 4500 mha and a 14 xl nemesis, speed master mono system, X445prop. Boat runs approxmately 45 mph. What motor could I use to achive 60

[Diegoboy]

How's your motor budget?

[lrm50]

thinking neu 1515 1.5y or 1.y

[Diegoboy]

I will assume your (2) 3S are in series?
I'd go with the 1Y

you beter tell him this is a SAW setup, 50,000rpm unloaded will detroy everything after 2 past.

I am a big fan of the 1515 1.5Y series on 6S, mid 30K rpms makes me smile, but having set up a DF33, and also 57 mph without trying, I would recommend a little more motor: 1521 1.5D on 5S or 1Y on 6S.

Destroy what?

It is not always the motor, there are many other considerations. Are you going to stay with your original setup minus the motor? Is the Castle esc high voltage?

Ok Diegoboy, let me make it clear here, you recommended him running 1515 1y 2200 kv on 6s, is it SAW, oval or sport running????

That is a very good question only the poster can reply on his aspirations. Run time, speed, and longevity of equipment

No Douggie, poster made thing clear, he ran 14xl for 45mph with x445, of course its oval or sport setup NOT SAW, and now he asking for 60mph setup, of course NOT SAW either, Diegoboy just gave him a killer setup that will burn everything in his mono, even his hair.

[Diegoboy]

That motor can spin a max of 60,000 per Neu.
so again I ask...
"Destroy what?"

Like i said, you will destroy EVERYTHING and maybe the only thing you have left is....bearings because its can handle 60k max

To answer question my 240 is low voltage. I build my boats for pleasure and love the speed the faster the better. This boat has alot of time and $$$$$ in for it to do only mid 40's I want faster

[Fluid]

The OP's boat is under-performing a bit with the current prop; it may be running wet or the cells aren't delivering top power. The first thing to do is to run a real speed prop, an m465 to start. Loosen the boat up a bit too, he should be seeing low-50s with the m645. Watch the heat but he should be okay.

I agree with Kevin, the 1515/1Y on 6S is a disaster waiting to happen. That is a 4S hydro motor and is totally unsuitable for 6S. How do I know this? First the numbers tell me so, along with my considerable experience. Second, a fellow Texas FE boater tried to get several 1515/1Y motors to run in racing hydros on 6S, but he could never keep a motor or ESC in one piece for more than a couple of charges. I lost count of the number of ESCs he destroyed and cells he puffed.

Depending on the budget the next motor to try would be the 1521/1Y and an m445, m545 or x450. This should get the OP around 60 mph safely, but he needs to watch the heat as he dials in the boat. That speed requires pretty smooth water but should be attainable. Watch that LV240 though, it is best used with a maximum of 4S power.
