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

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

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?

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.

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.
