Going to build a df33

[dannybj26]

Would the ose sv27 upgrade cable work for 6s of break ?

Wait, not trying to sound like weiner but you said you run it on 5s and 6s and it works great but it only ran 20ft on the first run?

Like I said, opinions will vary.

Well it went a little further than that I was just speaking metaphoric I got to run about a lap and a half and it fell out and have ran it since I got the new cable but it started slipping again so I stopped

A 4092 1700 kv on 6s will destroy that cable.

[Heaving Earth]

1400-1700 kv for 6s
1700-2000 for 5s
2000-2200 for 4s

Just my opinion

[dannybj26]

ok so anyone have a 4092 1480kv 3.5D for sale ?

You might have better luck posting in the wtb section if you're looking

Just be careful on the motor mount, you need a water jacket that will fit in between the mounting plate and rear support ring. If the jacket is too long it won't work

The DF33 is a 4s size boat. You will be way over powering the boat on 5 and 6s. I suspect that it could be submerged more than it will be upright. Get a 4s motor and 4s batteries and go have fun.

What determines a cell count on a hull? Makes no sense to me. Pick a cell voltage then pick a motor. What difference does it make...

[dannybj26]

so does anyone else have a df33 on this thread to post pics of ?

Well it's not a law or anything. It's experience. Jay's a racer as am I. After you've built, raced, crashed, stuffed and/or destroyed as many boats as we have you get a feel for size to power ratio.

It's from that kind of experience that racing rules were written for both organizations. The length limit for 4s boats is 34". Because that's around what works.

Of course not everyone races but those lengths are good rules of thumb.

[Heaving Earth]

I guess. But that doesn't really explain why a Df is a 4s boat to me. If you run a 2200 on 4s vs a 1700 on 5s, the 4s setup will havd more rpm, so why would 4s be better?
I thought the rules were written to make racing even.

[T.S.Davis]

For the same reason you wouldn't put 10s and 850kv in a delta 33. At some point the boat can't support it. You end up with a torpedo.

Plus, you can make a 5s setup that puts out the same rpm as a 4s but if you wanted you could do it different. Most people won't choose a 5s setup that spins the same as a 4s. Think about it this way. Say you have a 100 amp speedo that will go to 6s. On 4s you get 1480watts. On 6s you get 2220 watts. Minus efficiency of course. That's a bunch more power. The question you have to ask is "can the boat handle it?". If I max out a 6s at 220 amps or so in a delta33 what happens when I stuff? At reasonable speed it might be fine but if I push (like I know I will) to keep up with a 39" delta or a Seaducer will it survive in traffic? Will it stay together if I blow it off at 65mph with 6s2p in there? My experience.........nope.

[Heaving Earth]

I actually chose 5s over 4s in a 30" boat mainly because I've noticed that 5s has more power in the turns.
