Will the UL-1 motor work under the OB cover, and will the stock Stiletto ESC handle it?

[simo71]

Can't see why not. The stock ESC would be no issue as it is 60amp unit as well & you can program it timing etc unlike the UL-1 esc.

I'm fairly certain the stiletto motor is the same length as the ul-1 motor, I do not have a ul-1 motor on hand but the Proboat motor measures around 55mm long.

Put the ul1 motor in the stiletto. Cover barely fits. It's just a bit longer, but fits.

Hey Kev,
Are you going to run the UL-1 motor in yours?

Going to try to run after work this week. If not will run over the weekend. I will try to post a short video.

You just got the boat and you already want to upgrade

[Diesel6401]

Damage is already done steve, I just bought the stilleto motor off of him, Its going in the MG. Maybe a nice little pb upgrade over the BJ power already in the mg. Not sure if I wanna keep it all PB and buy the stilleto esc or just slap a different esc in it. Prob a seaking or swordfish 120

Ya. I'm bad.
HazeGry is polishing the OB... WOW!

[Brushless55]

We want a report of how well this motor is going to work in this hull!
IMO, this F1 should come with a higher kv motor

[ron1950]

a friend of mine polished the outboard and wow it will shine like crazy.....mirrior anyone?

Higher KV = Less Torque... And less runtime. Remember, this is targeted to a sport market, with racer appeal. Racers are expected to want to upgrade, change, etc... Plus, this hull is a little heavier than the VS-1. I am not expecting a miraculous performance increase with the Ul-1 motor, honestly. You'll need to prop it way down... < 40mm in my opinion to make it work.

By the way, the stock Stiletto motor is actually 1885KV, not 1800... or about 31,000RPM on 4S...

I'm thinking more in the lines of rpm over torque for this hull..

Prop accordingly, and let us know how it works out.

I'm not the one with the UL-1 can sitting on my Stiletto

[Diegoboy]

I am! Woo Hoo!
PB motor = 53mm long
UL-1 motor = 56mm long

I hope that adds at least a little back to the missing torque.

When you pull these motors apart, you'll find that the stator and rotors are exactly the same length... only the cans are different.

I've burned them all up and have torn them all down.

[Doug Smock]

Darin my brother. Ya got to learn not to burn. lol J/K

Danny I'm glad to see have a tunnel. Your going to have a blast with it next year!!

I burn... so you don't have to!

Thank you sir!

This statement is true for the PB BJ26/MG motors vs the UL-1...

The Stiletto motor is actually shorter inside by about 1/8". 1885KV, but less mass yet, so torque suffers.

Doug, I also got a cobra tunnel in custom blue/yellow coming. I picked up an OS lower unit from my LHS for that. I'll be needing all the tunnel gurus advice for that one...

[Diegoboy]

The stiletto will be my spec, and the cobra willbe my P

[hazegry]

danny your outboard is done

Just got back from running with the UL-1 motor. With Grim 42x55, I barely had it up to full throttle. Temps were great after 3 minutes. 88 degrees on the motor and esc. Too windy today to be comfortable at full throttle.

[Diegoboy]

nice report, even on a 42mm prop. SWEET

How do you think it did vs the stock motor?

How do you think it did vs the stock motor?

When I got the stiletto, I was seriously disappointed with the lack of speed. Now with the ul1 motor, I am timid to hit full throttle. There is now a serious increase in speed. So much that I will probably go down to a smaller prop. Expected the temps to increase. Temps went down a bit but that is probably due to the decrease in water temps. The last time I ran the stock motor the water temps were around 98 degrees. Today's water temps were around 80.

Today's run was with the stock esc but installed 5.5mm plugs and hyper performance flex. The stock cable unwound because it was in contact with the outboard housing at the motor end. Corrected by opening the hole just enough to clear the flex shaft. Check the alignment as Darin suggested. Also, if you use the ul1 motor the esc rev limiter with no load prevents the motor from operating out of water.

[Brushless55]

Right on man!
sounds like a great direction with this hull

[Diegoboy]

Awesome, my UL-1 motor should be here Monday afternoon, I can't wait!
