Motor upgrade

[FEJohn]

Is anyone out there running an upgraded motor? If so, any feedback would be great.

[Brushless55]

what are you looking for?

[FEJohn]

Something that puts out more power, I wanna keep the same esc tho if I can do that. Sorry it's a vage answer I just wanna know what my options are. Thanks!

[Brushless55]

More power?
are you looking for more speed?
these boats can do low 50s with the stock motor and esc

[FEJohn]

More speed, I want to safely run 2 3cell lipos without the motor or esc overheating. Do you know what a good set-up would be for this?

Thanks for your help,
John

[Brushless55]

Well first, how fast are you now?
if your only in the 40s like most are, then work on the setup to get the boat to the 50s..
What packs are your using? nimh or lipo and what size?
alot of new boaters want more speed but yet can't get the stock setup maxed out yet..
the stock esc and motor will take 5s with care..
I'm looking to try 5s this summer, like someone on here has done with great results!
I can get 52-53mph on my UL-1 running 4s, so 60mph on 5s should be doable
If you want more than 60mph look towards another hydro as this one would be close to maxed out at low 60s

What prop are you using to get into the 50s on stock power and 4s?

What prop are you using to get into the 50s on stock power and 4s?

I used Grimracer's L40 x 57/3 prop and water conditions were smooth with slight wind ripple on top.

I used Grimracer's L40 x 57/3 prop and water conditions were smooth with slight wind ripple on top.

I will have to order that prop and get it sharpened & balanced. Right now I run a x440 and I like it, but my boat runs low 40s. Not sure if that is average speed for that prop on that boat or not. I'm still learning how to set up boats correctly.

[Diesel6401]

Another question I have and this is a true noob question, but please bare with me I have only been in this hobby for less than 4 months, but how and with what do you measure the strut depth and angle? Like I said please bare with me, but if I don't ask I'll never know.

[Grimracer]

diesel,

I use a digital level and a solid rod protruding from the strut to measure the shaft angle.

To set the height I measure from the bottom transom of the boat to the work table below.

All measurements are taken with the boat resting on all three ride points.

This is the digital level that I have...

This is a must have for fine tuning ANY set up!

Thanx for the info Grim and Mike. You guys are great. Grim great boat I really love the ul-1 and I can't wait for the brushless cat you guys have in the works.

me to!

[Grimracer]

Thanks dudes.

I hope to be able to provide you with info on the boat soon but we still have a long way to go.

Lets see if I can find a pic for ya.. this is "Close" to the radio setup.. THIS IS AS GOOD AS IT GETS in FE RTRs...


Grim

EDIT

Im an idot.. thats a pic of the new cat.

Exact same here.

Man that looks awesome. Is that ul-1 esc/motor combo with a 2.4g tatic?

I am using 5400 30c lipos, The boat set-up is still stock. I do have the Grimracer L40 x 57/3 prop that I still gotta balance and sharpen. What set-up do you use too achieve the 52-53 mph range?

Thanks,
FEJohn

[Brushless55]

I need to look what prop I used to get that speed, it was a borrowed prop
once you get the strut set with the prop you will see 50mph!
and hold on cuz its fun

Thanks Brushless55! I cant wait untill spring so i can try it out.

[Brushless55]

OH man, the frozen lakes suck!
I'm wanting to finish breaking in my Gas KOS

[FEJohn]

Yeah it does suck! I only have a few good months here before the snow and ice returns. How do you like the KOS? Ive heard mix things about it, it looks fast tho. I got a Rio 51 w/ a zen m5that Im building.

[Brushless55]

I do like the Gas KOS because its a gasser, but for racing I would not want to go that direction because of the narrow hull..
I'm selling it to get a gas Hydro that my club is making bigger this season!

Here's the link to my 1st 50mph run and the set up I used:

You have more amps and should be able to run faster.

Thanks Crash, I was looking at yours a few days ago, looks good. I gotta wait for the warmer weather to come first then I'm going to try it out

[Brushless55]

I agree, these boats like amps!

Yeah, I wanna get a pair of MaxAmps 6500mah 2 cell lipos!

[Diesel6401]

So just for conversation & if I ever do decide to change motor/esc what would be the upgrade motor/esc of choice. Would a ammo 2600kv work with the stock esc? Would it be better to go with a 7xl,8xl,9xl etc... and if so what esc? Just throwing things out their for the sake of conversation & the orginal question wasn't truly answered...

[Rumdog]

Ammo 2600 is too high kv for 4s. My Ul-1 coulsn't handle the power of the 8xl. Lots of chine walking! The ammo 2300 may be an option. IMO the stock motor is plenty for this boat though. Maybe upgrade to a 120 amp esc and try propping up a tad.
