Help on motor and esc choice

[charlieb]

Hello all. I recently acquired a BBY 40" Winston eagle war eagle (lobster boat) and I am looking for advice on the power train.

What I was thinking was a NEU 1527 1D with 2 4s lipo packs to make a 8s.

now being fairly new to electrics I thought I would ask the experts opinion on what set up I should run and what speeds to expect, I want well over 60mph, will be used for racing.

Thanks for the help

Welcome to OSE Charlie.

A 1527 1D is too hot for 8S unless you want to go 100mph once. It can be used using 4 cells with two parallel packs to make 4S2P. You will need a strong 240+ amp controller to make that motor run properly. If you wanted to run 8S, you should look at a 1527 1Y.

You can always call Randy at BBY who makes the hull for suggestions.

so a 1Y instead of a 1D ? what is the difference and will there be a huge speed difference? I would like to hit 80+ not sure if that is possible reliably.
thanks for the input

Well first are you planning on running 8S1P or 4S2P? Are you planning on racing? This will make a difference in which direction you go. 80 mph is obtainable with either choice, but easier on the controller if you go with 8S1P, a 1527 1Y and a reasonable controller.

was going to run 2 4s in series. and yes it will be raced. (oval right hand turns, not SAW) I may switch to a single 8s battery, all depends on room and such

[charlieb]

why would there be a difference between 1 - 8s pack or 2 - 4s packs run in series?

any recommendation on the controller? brand , size etc..

[RaceMechaniX]

S sport Hydro is rarely raced not even at the National level, so I assume you plan on running in open?

There is no difference between 2 4S in series and a single 8S brick besides the extra connection. There are fewer chargers that can directly charge a single 8S brick unless it is split up.

Look at the SF300 Pro or Castle 240 ICE if you can find one.

[charlieb]

that's good to know on the lack of difference. My chargers only do up to 7s. I may even drop down to a 6s so I can fall in the Q class, but yeah mainly open class. so a 1527 1Y with a SF300 pro controller and 2 4s packs in series. with this setup and the right prop any guess on speed? or would you rec a diff motor ?

[RaceMechaniX]

For 6S your best match would be a 1527 1.5D which has a kv near 1500. That would be a very solid set-up and with a X450/3 or 1455 you are looking at speeds in the 70's assuming the hull can be set-up.

I am a little hard to get a hold of now a days. I work a part time job Tuesday threw Friday/ after noon for 5 Hr. a day. I am running the 1527 1D on 4S2P with great results. I have the 1527 1.5D for my next run at S Sport hydro (SAW) if I ever have any free time again.

Hello Randy :)
I am watching the mail closely, waiting for the boat you shipped me to show. I cant wait to get it painted and in the water. Sounds like the 1527 1D with a good ESC is the way to go and I can play with battery and prop configuration to get what I need for speed out of it

[RandyatBBY]

I have tracking in my car I will look for it.

[RandyatBBY]

I emailed you the tracking info.

[charlieb]

Thanks Randy :)

This sale went wrong. Charley wanted to return the boat. I wanted to think about it and come up with a plan. This morning before I had a chance to do anything he filed a dispute claim with PayPal against my account. He has not returned the boat either. As far as I am concerned.... If he does not return my product and takes my money first he is a thief. You guys be careful of him, he is a loose cannon.
