Motor upgrade

[Diesel6401]

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.

I agree that stock power is enough. My goal is to push the stock setup fast as I can 50+ hopefully, but after that... plus I want to use my ul setup in my sv which gives me a reason (or explanation to the wife) to buy a new motor/esc...

I would like to try a 7XL with a small prop and see what happens

[ncornacchi]

I've got a Fieago 7XL, 2370KV with Etti 150 and Grim 57/3 in the UL1 and it runs like a charm. But IMO, the Nue 1515Y with Woltz .078" wire drive, M440 and the CC240 is the way to go. We run consistant 48-50mph (data logged) on two other stock UL1's and the two setups above pass them like they are standing still! Just have to make some lead adapters this winter for the EagleTree ( deans ultra to 5.5 bullet) and see if I can fry an Eagle Tree on a Nue1515

a 7XL with a 57mm prop?

I would also like to try this motor as well. Is a 120a esc enough for this motor and maybe 5 or 6s? I really don't want to shell out the $$$ on a etti I rather buy like a turnigy marine 120a if it would work well in this application.

I think he means a Grim L40x57/3. 57mm pitch

the 120a esc should get it done, and on 4s will be a monster..

5 or 6s is too much voltage for a 7xl

Sorry for the typo...It;s an L40x57/3 Grim prop

[ncornacchi]

Off subject, but.....I once got a set of 300A CT's shipped to me instead of some guy who ordered them from Norway...Called EagleTree and got them off to the guy..but I then started wondering that when you exceed the ELoggers amp range (I think its 100A) if you couldn't buy these CT expanders for the hotter setups instead of frying the logger. Plus, I think it stinks that they have the deans connector built in to them, limiting the current..I made some 5.5 to deans adapter jumpers, but still feel that I'm probabbly gonna cook something..That's why I'm afraid to use them in the Nue/Fieago...thats alright, the only thing we have up here in new england is block ice and snow...

Motor specs rate it at 2s-6s. Even though it is rated for it, is it recommended not to use anything above 4s?

[Diesel6401]

Would a turnigy 180a esc fit into the hull of a ul-1?

yes, the rpm is getting very high on anything over 4s.

[Rumdog]

I fit that esc into a vacu-pickle, but it was a tight fit. It is probably too tall for the ul-1.

[Diesel6401]

Good to know, this will probalby be a new motor/esc combo for my ul-1. I just read about the new venom boats 2 seconds ago so new ul-1 power is going to have to wait. I just got a grim 40x57/3 and strut depth is set to 1" so soon as weather breaks I can test it this setup then work on strut adjustment. Looking forward to it.

I'll stick to the 120a whenever I get some more cash.

So does the Feigo 7xl mount up directly to the stock motor mount without changing anything? Does it come with new mount bolts or do I use the old stock bolts currently installed? New guy quesitons i know

[Brushless55]

Oh man!
a 7XL in a UL-1, all I can say is yes it will mount up just fine
make sure you bring someone with a video cam, cuz we all want to see this one run..

Thanks and does it come with new bolts or use the old ones? Their are a few other things I need to do to the ul and also gotta wait for weather to clear and it will be ready to go. I am currently hitting high 40s (46-47) close to 50 but can't get over the hump. I honestly think the boat will do over 50 with my setup, but I don't have the best gps (kinda big) and I think it is weighing me down due to the size of it. I am running 1" strut depth and a sharpened and balanced (by egneg) grim 40x57/3.

[Brushless55]

the motor does not come with new bolts, you should be able to use the stock ones..
what batteries are you using?
are they at least 30c?

I will be using 2 2s Zippy 4500mah 30c and 2 2s zippy 5000mah 30c heres the esc i ordered http://www.hobbycity.com/hobbycity/s...ter_Cooled_ESC

have you used these batteries on the first go around with your UL-1?

[Diesel6401]

Yes i have, when I ordered the boat the 4500 30c where the first batteries I got with it which have several runs on them. The 5000 30c I just got and they only have 2 runs on them and work wonderfully temps where good on both sets of batteries. I just switched the stock esc to 5.5mm bullets.

On this new motor/esc combo I am going to use are the 5.5mm bullets i mentioned above over kill for the 3 wires for esc to motor connection or ok?

[Brushless55]

no such thing as over kill, trying to get more amps to our motors
I'm thinking of changing mine to 4mm on the motor

GREAT, every connection on the new setup will be 5.5 then. sweeeeeet, I can't wait to get this thing in action. After I get everything installed in the ul I am going to take the stock ul esc/motor and put it in my SV...

How do you feel about the esc I ordered? Do you think it will be up to the task?!?

[Brushless55]

That esc should do just fine, just watch your temps on the first run

Grimracer did you delete the picture of the new cat? I can't find it.
