Just curious if anyone has thought of running a ammo 2600 in this on 3s/4s setups with a smaller diameter prop of course, like a x437/3. Just wondering. I'm really interested in this boat... Never owned a tunnel, but when I do this would be it. Also curious on how this stacks up against the UL-1 power VS1's with this running ul1 gear of course. Just wondering.Comment

pick up a stiletto and a vs-1 and see the difference in weight.....all things considered id go vs-1 if i had it to do again.....never tryed any other motor then the ul-1 in my stiletto.....it runs well now but still not into the 40's ....think i need to adjust the motor angle again and maybe a new prop as it runs very cool now with the 640MY RETIREMENT PLAN?????.....POWERBALL

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.Comment

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.Darin E. Jordan - Renton, WA

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.Comment

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.Comment

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??Darin E. Jordan - Renton, WA

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