Stiletto Race Prep

Put a Losi Xcelorin 1/8th Scale motor on the stock outboard tonight. 2400KV 4-Pole, very similiar to a Neu in construction. Used a Neu 1509 water jacket on it, which fits perfectly. Just have to remove the endbell screws to slide it on, the reinstall.

ESC is now a Hydra 240.

Fabbed a plywood radio-box top to replace the platic stock one. I needed a little more room under the lid, and also figured this would be easier to tape down. Would have liked to have made if from some G10, but I didn't have any that was thin/light enough, so this will do. Put a coat of laminating epoxy on it, and it's ready to go.

Going to play with this tomorrow at the Puget Sound Model Boat Club's NAMBA D8 2-lap event. Going to throw an Octua 440/3 on there, a 5200mah ThunderPower 50C 4S1P pack, and see what kind of 2-lap time I can navigate.

This could be interesting!

I hope someone gets a video for you!

darin...ran the ul-1 motor and the new hull tonight...(long story on the hull lol)....faster but still needs some trim work on the motor....do u have pos trim in your motor?mine is nutral and seems like there is more speed there somewhere....maybe some up and some pos trim will do it good luck with that horse u just created

I just cut some thick lexan sheet to make a new battery box cover. Now I can effectively tape completely around the box.

Also packed the push pull cable bellows with marine grease, as well as the esc cable bellow to restrict flooding the radio compartment.

Darin - regarding blueprinting the sponsons. Do you sand all three ride surfaces?

Thanks,
JD

Still having a leak into the receiver box. Time to put a boot over the switch, or put in inside the box.

Darin, would it not be better to have the canopy attaching pins affixed to the hull and the locating holes on the canopy?

My lexan battery hatch cover

i aggree

i aggree on the pins being in the hull sealed instead of two holes below the water line into the hull......i know its not hard to seal but dont see why i should have to lol

like the lexan cover i may have to get busy on one myself///

I don't know. Couldn't hurt. I never get water inside the hull, but I'm still getting it inside the battery box and radio box, and I can't really tell where it's coming from.

By the way... the Losi 2400KV Xcelorin 1/8th scale motor... 440/3... HOLY CRAP! Need to work on setup, because it accellerated itself right off the water! Time to do some testing and get it setup...

[ron1950]

i guess i said that cause i am also getting water in batterybox and a few drops into the rx area....and also i cant find where its comeing from....now tell us more about the beast with the big motor..

I rolled over today, and when I recovered it, the hull had lots of water in it.

Im thinking its either getting in from the canopy pin locations up front (although inspection tonight they appear to be plugged already), or the culpret is the blind nut locations for the motor mount or canopy screws.

Ran the 40x52/3 prop today. Like the speed and turning, but had too much tilt on the motor. Carried the nose really high and Lots of cavitation once you set the front to turn tight (felt like slipping clutch).

X442 Octura was nice. I'll raise the motor depth a little next time to see about getting some more speed.

Make-A-Wake took a few videos. Maybe he will post them up of the runs.

Only thing I had to compare to was a few Ms Gieko's that are screaming.

This just sounds so wrong and right at the same time!

Do you get water in those compartments just by running her? I never get water anywhere unless I flip it, I used to get some water in the hull before, but not since I plugged the holes in the front with silicone.

I was running a Feigao 11L today (2300Kv) on 4S and a M440, it was running great until I hit LVC, or at least I thought I did, I brought her back in and when I opened the hatch there was a little bit of smoke trapped inside. One cap blew and the other was puffed.

Lesson learned: don't even try to take the stock ESC apart, it's one solid block of epoxy , if you need to replace the caps just wiggle them until they get free of the epoxy and carefully pull them straight out leaving the contacts attached to the PCB. You can then solder the new caps on those contacts.

I might end up replacing the ESC anyway, but I'm not very happy that a perfectly good ESC can become useless because you can't replace $1 worth of caps...

[GP73]

I forgot one thing about the hatch: if you trim the stock one by cutting along the ridge it becomes much easier to tape and much more waterproof.

i was getting water into the battery compartment and couldnt find out where it was comeing from....could only be from the water cooling tubes so a friend suggested to wire tie the hose onto the the metal cooling tips of the esc and next run ...no water so guess i found my leak...

[JDCrow]

I believe Ive found the source of flooding the receiver box.

The first correction is stop capsizing. But more controllable is the lack of watertight seal on the switch. Just inspected it, and there is plenty of gap between the insert and the threaded rod. There is a tag on the ballend of the pull rod, but something appears to be missing. Time to review the manual and see what, if anything is suppose to be attached to it.

Time to practice safe boating and put a raincoat over the switch.

I bought a Hyper Performance 3.5 Bullet Shaft, but found that the Allen screws do probably not match the metric system; my 1.5mm Allen key was too small, the 2.0mm too big. Do you have a different system of units for Allen keys in the US, and what would the right key be? ...
