Motor Size for JAE FE Q class Rigger

[krashkrieg]

Hello all,
I'm pretty new to the forum and mostly a lurker obtaining information. Thanks to everyone here for that.
Finally I am building an FE boat and looking for some input on motor size for my first build.
It will be the new JAE Q class rigger built for racing.

Nue 1527 1Y is what most are running. 1250 rpm per volt.

If I was buying fresh I would maybe do a 1530/1.5d or even a 1527/1.5d for a rigger like that.

Another interesting wind might be a 1524/1.5d. The kv is bit high for my liking but in a rigger it could work.

Not sure about space in a JAE but you could even have Steve wind you a 2205 or a 2210 in the 1500kv range. Nice thing about the 22 series motors is that they are 8 pole instead of 4 pole. Acceleration is quite disturbing with a giant rotor and 8 poles. This winter I'll likely build something like that myself.

Terry,

Only the 22xx-24 series ar 8 pole motors. The 22xx-12 are 4 pole Motors. Not to pick but the more common boat motors are the 12 stator Motors.
I disagree on the viability of the 22xx-12 motors. I love my 2215 but my 2220 and 2230 are dogs compared to the lehners. I know we go back and forth all the time about efficiency of 2 versus 4 poles but my Lehners just have more power. My 2280/5 Lehner rocks in my Q Sport Hydro.

[T.S.Davis]

I stand corrected. I just noticed too that the 24 stator motors are only rated to 30000rpm. Interesting.

Not trying to jack the thread but I have two 2215 and a 2217. The 1Y is a monster but the other two I can't seem to find the sweet spot on. Still searching.

Crikey, I missed the boat on this one, I have the Minisprint, .12 and .21FE all set up for FE but have not heard of a Q version, is there one and if so where can I find it? I looked at Zipkets where the other kits can be found with no joy and NEStuff where the other plans can be found with no joy there either. Are you converting the .45 to FE? I did that with the .12 and was tempted to do it again bigger.

So I realize there are a lot of "NEU" or nothing guys on here but I'm a newbie not needing the best motors.

Does anyone have suggestions for those of us that don't mind running with the Leopards?

The guys at Zipp Kits have it now, just call. It will be on the web site soon.
I believe it's basically a .45 that has a taller body to accomodate the batteries.
There are 3 already in my district and I like bigger boats, so thought i'd give it a shot for a first build.

Sorry man. I didn't know you meant at a reasonable price.

I'm weird about motors. I try to get the biggest rotor I can at the kv I want. Sometimes I end up with too fat a motor that way though.

Maybe try a TP4060 1400kv. Should get you there for $119. In stock in the US too. I would shoot for something in the 1400 to 200 kv range. The lower end making for less amp draw and maybe more prop.

TS Davis Thanks for the advice...
What do you gain or loose going with longer / shorter length can? 4060 vs let's say 4074 or 4082

[photohoward1]

The mass dissipates the heat better. That's why terry lines the big rotors. Me too. Anything leopard 4082 or larger in the 1600 to 2000 range will work fine.

[T.S.Davis]

I have no data to prove it but in my feeble brain I always thinks....object in motion tends to stay in motion.....blah dee blah dee blah. More rotor mass means more tendency.
