Jees...I have a PB Boeing 787 hull...cowl never cut...is yours FE?
If so, sure would be interested in the set-up!
Thanks!

look like thats what he said to me.

Not sure if that is a UL1 motor behind a stiletto or ?
that's why I ask

[hazegry]

he was talking about a ul1 motor on a different tunnel sounds like a good place to start

[Darin Jordan]

Guys... I have never run a UL1 motor, or any other AQ motor, on my Stiletto. I've tested the 1800KV and 1500KV ProBoat motors, as well as a 1/8th scale Losi Xcelorin 2400KV setup.

My comments on the 42x55 were for that prop on a UL-1 motor powering a VS-1 tunnel. That is a much smaller, and much lighter setup. I'm not sure how it would work on a Stiletto, but it should be a safe place to start.

My prop guy says it can be cupped to that number but will not have that much pitch..to small.
I'll give it a go....................

If someone actually measures a 42x55, they will find that it has a LOT more pitch than it's advertised to have... I'm not sure where they got their 55mm number (2.16"), but the one I measured has 3.1675" at the 60% point, and 4.1442" out at around the 80% point (about 1/4" in from the tip, I'm guessing on the % part... )

This is a stock prop with just a hair of bending done out near the tips on the trailing edge.

I found similiar results with the 45x55 I measured.

In fact... I don't trust prop charts anymore at all, because most of the props I've actually measured seem to defy the prop charts when actually measured. It's some very interesting and useful data once you start documenting things.

Ok great, thanks for the info.. I quess I'll find out when I send him a prop. Then he can see what's up with the size and go from there.

guys , quick question , is the ESC already programmed to use LIPO Batterys ?? Thks

[colormegone]

Yes it is... I called Pro Boat before I took it out yesterday for it's maiden run

Hey guys newbie here just got the Stiletto ..She is straight outta the box.....I was wondering how i hook up only 1 battery...I have 2 Brand new just got them last week.....
Turnigy Nano-Tech 6000mAh 4 cell 14.8 volt 25c-50c


and i want to run it in this boat ...but we have 2 battery connectors and no instructions on how to hook up just one...Any help would be appreciated...

Also i watch a youtube video of the boat with a Grim Racer 40x52/3 prop ....can i just order this and use it ...or do i have to do something to it?

The easiest way is to solder up a reverse Y harness. But I don't recommend that. Deans connectors are right on the borderline of not being able to handle the current that this model draws. The best way is to remove the pair of deans and install bullet connectors. Such as the Castle Creations 6.5mm ones. Then it's also easy to use two 2s packs in the future or your single 4S pack with out using any inefficient Y harnesses.

I don't recommend upping the prop size. The motor is already working hard on the current prop. The outdrive height and pitch affect the ride quite a bit, so get the feel for it and let us know how it goes.

Thanx for that but being TOTALLY NEW ..i dont think i understand the lingo hahaha......you said no Y harness and NO Deans ..this didnt come with deans
this is what i have ...also the wire to the ESC is only 14 ga and the battery is 10ga.....I dont see how that is at the upper current level for a deans....We use Deans in 1/8 E Buggy with a 1900kv motor and the same battery with deans and never a problem...NOT arguing just trying to be sure my friend...Also they would have given bigger than 14ga i would think if the current was really that crazy no?........and REALLY on the prop?...from all the threads i have read it seems to be what people change the most also this battery comes with 4mm bullets with 10ga wire..so i think the 6.5 may be excessive What i thought was just take the red from one side and the black from the other connector and make 1...I have Deans but no Bullets like on the battery but they can be ordered if that s the best way to go

That's interesting. Mine came with connectors that are different than your black ones, those are called Traxxas High Current Connectors.

Well, even though I like castle bullet connectors, you are probably best off choosing to go with the Traxxas connectors because they're already soldered on your ESC or the red one because it's already on the battery. Those are 4mm bullets.

If you go Traxxas, the gold blades are very firmly inserted but can be pushed out. Hold the case with pliers, push the gold blade back through the wire hole. I've used a straight edge screw driver, but be careful not to stab yourself. Only do the wire that's not connected to the esc. Now grab the other connector and push both wires out. Take the other wire attached to the ESC and insert that blade in the housing so you're down to a single connector. Cut the connector off your battery, solder on a traxxas. Check voltage polarity before soldering and again before connecting.

If you go with the 4mm bullets, I don't know where to get those red connectors.

The prop: long story, but yeah, everybody wants to go faster. I looked at the draw for this class motor and she's givin it all she's got. If I was gonna go faster I would change the motor.

Cool thanx for that! ...So in essence i am going to eliminate the red wire that connects the 2 connectors together and make 1 connection from the 2 wires(red/black) from the esc...Correct?

[Darin Jordan]

I have NEVER seen a Stiletto that came with those Traxxas connectors... That's a new one...

To run a single pack is very simple... One side of the ESC wiring harness should have either two red, or two black wires going to it. Just make a jumper to tie these together on one side of the harness, and then plug in on the other side.

OR, if you want to solder on new contacts, just cut the red wire, and the black wire, near the existing contacts, and solder on a single set to the black and red wires.

As for Props... Jury is still out for me as to what is the "right" prop, but the Grim prop I tested in that video had a little bit of work done to it. Sharpened, balanced, back-cut, detounged, etc... There are lots of other prop options that will also work. An Octura X440/3 works well too.
