Esc for a tp 4070 1090kv

[zhevers]

I'm trying to find the right esc for a tp 4070 1090kv. I'm going to be building a twin set up if it will all fit.

I'm looking at the dual 100a esc's that are being sold on the forum but I'm not sure if a 100a hv esc capable of 8s will be enough for one motor or if I'll need to go to a 200+ amp esc.

Looking for help and advise not grilling. Thanks

How big of a boat and what type is it? and what do you plan on doing with it?

Is it a 2 x 8S setup or 2 x 10S ? What is the hull?

Daytona CF. Max I would want to do I think is 8s per motor. Dual motor set up. One battery per motor

That's a lot of power for that hull, I would go at least 200amp. I've got a Cheetah with twin TP4060s and 200amp Swordfish Pro Pluses, it works real nice.

@flraptor07. That's a single set up I'm assuming

No the Cheetah is a twin setup, here's a video of it running. https://www.youtube.com/watch?v=CWlC...4Q-xrOOtP2wC-8

Nice run with the Cheetah

Where do you want to put 2x8S in a Daytona?
In a transom 5S 5000mAh is a maximum, 6S are too big.

You can try 2x5S with 1800/1900kV motors, TP4030 or TP4040 or NEU 1512 or .....

The batteries is a bridge I haven't crossed yet. I'm starting to find that a hull this size is not that big haha

tp 4070 1090kv are for this cat?...

I say sell that motor, then buy two 4060's and two seaking 180 esc 's. If your going to run 4s in each sponson, get around a 2200kv motor. If your going to run 3s in each sponson, then run in series and then run the power to both esc's, use about a 1500-1800kv motor for each side. If you fo a single, I'd still sell that motor and get a higher kv. A 4060 1870kv on 6s will push it into the 70's. You could also do a 4070 150 kv on 7s.....my preferred combo would be 4060 1870kv, seaking 180. ...I just build a 32" cat with this same combo and it runs 77mph with ease and I did no tweaking to it. With a sharpened rudder and tweaked with good batteries, it would do 80+.

I'm agree with kfxguy 2x4S or 2x5S with 35000 rpm unload is the rule to choose the motors.

I prefer 2x5S because autonomy is better. In that case here is a very good motor : http://www.hobbyking.com/hobbyking/s...arehouse_.html
2 x Seaking 120A should be enough

Thanks guys. I'm working with Travis on the build of my Daytona. I have the motor in the swap shop to try and get a higher kv replacement.

As with many of us, I have changed my build plan and going to go with a single set up. Looking for a Neu or Tp something that can handle the higher rpm

[iridebikes247]

I would go with the TP motor, take Travis' advice with swapping out. Recently I compared the tp 4070 to my neu 1530 I think the 4070 weighed like 605 grams without jacket, Two of em with 6s would just be way too heavy for that hull. Last thing you want with a light weight hull is a heavy motor trying to yank itself free in a crash.
