Project Apparition!

Try the next size smaller stuffing tube and slide it into the original. Run linerless. Thats how all my boats are now. That 2650 should get up and go well. I run one in a 1/8 scale buggy on 3 and 4s. On 4s, I've hit 59mph with that bad boy!

Yeah, I pulled it from an E-Revo that I used to run with paddle tires in the sand. Basically wide open till it ran out of juice. It's a great 4s motor. I had it geared at 52.5 mph top end and ran it with two 4s 20c 4k packs for almost a half hour at a go. Good stuff.

OK, so smaller brass tube and lose the liner completely. Done. I'm considering a wire drive too, maybe a setup to match the Genesis wire Jeff just made for me. Less maintenance than a cable.

So, any bets on how fast she will go tomorrow?

I have stuffing tube to fit the new cables if that is what you are running. If oyu got the cables from me I will send you some tubes. They have plenty of room.

Wow...must have been hot...surprised the stuffing tubes did not melt.

Yeah, me too. I really don't know what made this one so tight. It was so tight, I couldn't re-install it with the cable in the tube.

This is one of the 4mm strut setups with the square drive and the separate hard prop shaft.

For now, I'm just going to run without the liner, but may have you make some more of those 078 wire drives. Like 4 more, but will wait until I have the other project at hand and see what I want to do then.

So the factory teflon for the 4mm flex is to tight from factory, im going to have to check mine when i get my boat,,,,seller said it had the factory 4mm setup,,,

It may just be mine for whatever reason, but yeah, always good to check drive cable clearance.

If you're talking about the boat you got from Justin, then it's probably good to go. I doubt he would miss any details like that.

This mornings run was fun, but really slow. Didn't break 40mph. Holy hell that prop is too small!

Temps were all under a hundred after a few minutes in the water. Didn't figure it could get hot, it reached peak RPM almost instantly and didn't even act like it was under a load.

OK, so on goes the 442 and more water later today. It's windy so it's a drive to flat water. Just so happens it's fresh water. =)

yeah got it from him hope its nice but gotta finish my single Skunk cat first, i went to lowes yesterday to look for some hooks to make into air rams for the hatch but didnt have what i was hoping for o well,,PS what speed are you shooting for,,,

[FighterCat57]

Hmmm. I wonder, can I overheat an ESC with too small of a prop? Doesn't make sense, but here goes:

Speeds are only in the 30's on 3s and 4s using the 42/3 prop. After a loop or two, the ESC get's hot and goes into protection mode. Like 1/2 throttle. I bring it in and the ESC is 170 or so and the motor is 90 and cells are 90. It jumps to full throttle effortlessly and acts like it needs more prop, but I'm puzzled by the ESC heat.

I reset the connection and repeated this process with different props and cell packs.

Good water flow. Same behavior on 3s, 4s and with smaller props. 40mm & 42mm.

Should I go bigger on the prop?

You could help the heat if you stop gunnin the boat on and off .Everytime you do that your heating up the esc.Driving styles have alot to do with the different data people end up with . Not criticizing but I wouldnt "play" like that with an experimental setup unless u dont care about tearing things up. We talk about hp like 1 is nothing. Think about 1 horse being hooked up to you boat. Can he tear it up?

to answer your question about small props that all probable depends on the rpm rating of the motor.

[Xfactor]

She is fast tho but the motorboating of the throttle hurts you. When it get on step leave it there and run the darn thing no more than two minutes If you can hold your hand on the motor for 20 seconds or better then keep pushing if not drop the prop down. Always I mean always lube your shaft lol. That didnt sound rite anyway.Check your timing too.

[FighterCat57]

Thanks for all the replies and the info on lubing my shaft and playing with my throttle. Please read previous posts for aggregate information pertaining to said maintenance.

The runs were accomplished by gently launching the boat in the water from shore and guiding it in large circles at open throttle, eased from none to full in about 1-2 seconds. About a minute or less into that pattern, the ESC drops into a failsafe mode (I think) which only revs to about what 1/2 throttle would be. At that point, I guide it to shore. Temps are as stated above.

There is a good amount of splash, but seems like it might be running a little wet. Perhaps that's the key. I can imagine if the hull is not up out of the water enough that it would put more load and increase amp draw.

Now, show of hands... who was thinking, "it's because you chunked up a drive cable and it's binding up"

Guess my little Neu-Castle is making some power after all. I did get a reading of over 1500 watts on the first run out, perhaps this is when the cable let loose. Explains the heavy amp draw and low motor temp. It never had a chance to catch it's breath.

OK, so new drive cable. Hey Jeff, want to make another one of those 4mm cables like the one I just ordered? I'll take that 4mm ball bearing strut too while you're at it... and a 5mm - 078 hex.

Might need to put Jeff on account terms if this keeps up.


PS- this also addresses the tight liner issue. It appears the cable had already started expanding at that point. These cables are weird.

We can work it out. Yes, if that cable was going then that is the problem.

[FighterCat57]

OK, new cable installed, all is well drive wise, but not really. All temps under 100 and the ESC still goes into "safety mode" after about 1.5 minutes. Top speed was only about 38mph. Yikes. Something is still really wrong.

The strut is setup with slight positive angle even with the sponsons and the COG is just under 8". It comes up to plane nicely, but now pulls to the right.

I don't recall what the solution was for pulling right on the single cats?
