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.

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

You just got the boat and you already want to upgrade :w00t:

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

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...

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.

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.

10-02-2010, 11:17 PM

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.

I know, replaced a stock motor, but for some reason, the stock motor, with both the stock and 42x55 props, would not spool up very fast at all. All esc settings set identical to yours, but still no performance. Curious if the hyper performance flex made any difference. Had to readjust for the extra length, but now runs great with different motor. Any ideas?

Darin Jordan

Open to suggestions for more props

Actually, the 42x55 with some tweaking will be very close. It needs to have some pitch added to it to be where it will really shine, but also have some load taken off the prop. If you back-cut it a bit... start at .030" or so, and start pitching it up a little at a time, I think you'll get better.

Remember, this boat is a bit heavier, being a RTR production boat, and not a purpose built race boat, so it's not going to work the same as a lighter VS-1 or Cobra or ???...

Gonna run a single 5000mah 4s 30c pack per O/B. Do you guys think the 2030kv's will run cool enough or should I get the 1800kv's.

Should bolt right on. You'll need to make sure you install the coupler at exactly the same distance from the endbell. Otherwise, it should be a bolt-on...

Just installed a ul-1 motor in one of my stilletto outboards. Motor and mount holes are a tad off. Start all 4 screws, and alternate tightening them a few turn each until tight. It fits, just a little snug! Also picked up some hyperformance flex cables that look much better and straighter than the stockers. Slightly longer than stock, so the motor coupler has to slide all the way up the motor shaft. It looks like a good fit as well.

Yes, I've tried a Feigao 11L (2300Kv) and I didn't see a great improvement in speed, that was with a x437/3. But I did see smoke coming out of the stock ESC and later a Suppo 70A... :lol:

I've also tried a Turnigy 500 1800Kv outrunnner with the same prop and it was better than the Feigao.

I would stick to the stock 1800Kv or Ul-1 and play with the prop size/pitch as suggested by Darin. I'm wondering if the Y537/3 is worth a try too.

DING-DING-DING-DING...

If you guys have paid any attention at all to what I've been saying, and also to my MG testing EagleTree Data... you'll see that simply going up in KV isn't the answer... You go up in KV, but leave motor dimensions the same, you are gaining RPM at the expense of torque. The end result is about the same amount of power, laid down in a different manner.

I have solid data showing a STOCK motored MG racing in the 45-47mph range. It's done with prop and setup. Going to a 2030KV UL-1 motor on a 6+ lbs boat (STLO) and having to run a tiny prop to keep it from overheating is the wrong direction. The stock MG 1500 motor with a 42-25mm prop with around 4.0" of pitch (last .250 or so of the blade) will have this boat flying, and not overamping it. Will have more grunt out of the turns, and through the turns. Setup will be a little more critical, as the added pitch can torque the hull more, but the setup would fly.

NOW, if you want Higher KV, you will really want to go with a LARGE motor... the 1515 1Y or something with more mass, longer rotor, etc.

I tried like CRAZY to make the Stiletto light, but it's a bigger boat, with cool features, and a production boat to boot. Only so much weight savings was possible and still keep it strong enough to survive the thrashing you guys will put it under! ;)

So, my recommendation would be to either upgrade to a 1/8th scale buggy sized motor, or a 1515 series Neu or similar. I have a Losi Xcelorin 1/8th scale 2100KV buggy motor that simply ROCKs on mine... and I also was thinking of trying a Castle 1512 1800KV or similar. ESC changes will be required, of course.

If you want to stay P-Spec legal, then I'd suggest you try the 1500 MG motor, or the 1800 STLO motor.

Very good sir. I just started thinking really hard about this so haven't had a chance to review everything you said darin which is Y i may have missed your information on that, or I read it and forgot I read it which is always possible. I have a spare BJ/MG motor and with the stock 60 amp esc may be nice bit of head room for playing around with some props. I also have a NIB CC 1512 1800kv which I could use. Darin I imagine the motor cover would work with the BJ motor and not the CC motor, is that correct? Also would the 1512 with the jacket fit OK? Never owned a tunnel hull, getting kinda excited.

Wouldn't that defeat the purpose though? More mass=more weight on the boat? :confused2:

Maybe a Leopard 4060/1900Kv or 4065/1800Kv are a better option? If we are to believe the mfg specs they are 295g and 311g respectively, which is less than the 1512 (370g) and the 1515 (424g) .

Not sure how they compare in performance though.

Just for reference, the stock motor is 206g.

Darin Jordan

12-03-2010, 04:52 PM

Wouldn't that defeat the purpose though? More mass=more weight on the boat? :confused2:

With this type of power... weight to KEEP the boat on the water becomes more of an issue... :thumbup:

As an example... I put a Losi Xcelorin 2400KV motor with a Hydra 240 and a lightly massaged X440/3 on my Stiletto and attempted a 2-Lap record run... Need to do a little more tuning, because the boat was BALLISTIC and just flew off the water on the backstretch at a speed I'd estimate to be approaching mid-50s.

With this type of power... weight to KEEP the boat on the water becomes more of an issue... :thumbup:

As an example... I put a Losi Xcelorin 2400KV motor with a Hydra 240 and a lightly massaged X440/3 on my Stiletto and attempted a 2-Lap record run... Need to do a little more tuning, because the boat was BALLISTIC and just flew off the water on the backstretch at a speed I'd estimate to be approaching mid-50s.

Diesel... I had to mod the motor cover to fit around this larger motor, but it looks pretty cool when done, don't you think?? :rockon2:

Darin looks like I'm getting ready to pull the trigger on this thing. Another quick question I know you had to mod the cover to fit over the motor, but I wanted to just make sure and verify the water jacket on the 1512 will fit under that cover. I can't tell if you have any water-cooling on the losi motor or not.

Ron you still looking to buy a Stiletto 60amp esc?
