P1 kos 35" offset rudder.

Ok, last pic.[ATTACH=CONFIG]71243[/ATTACH], sorry to take this long. Slow at computer

The blue water hose that go,s out the side of the boat,
And the two wire black and red that look like their both together in the black thing.
That is what looked scary to me.

Do your wires from the esc go all the way around the boat to the other side were the water outlet is ?

[tlandauer]

Thanks for the concern, really appreciate it. The photo makes it look like the two wires are touching, It is not and the black neg is completely covered in the heat shrink tube cap. But I will be more careful. Yes, the battery leads from the ESC is pointing to the back, on starboardside, when I connect, the wires are away from the turning motor. And I tape them flush on the batteries body, making sure no chance of being caught with the rotor. Having said that, I still had the misfortune of the water hose caught in the motor causing motor failure. Now off I have 50 miles to drive to concert hall, Thanks for all the threads, want to know more of your on-going tests.

Look at my pictures in post #31 and at the far right picture.
You would measure 1 1/4" from right side corner of the boat to my trim tab adjusting bar,
That has the bolt with lock nut so it wont move.

I still can make it work its not the same as what I have, My rudder is from center of boat over, 1 1/2"
Just will need to know your measurement on yours.

[tlandauer]

Hi, Thanks for the prompt, My measurement is 1 3/4'' from the corner to the center of the bolt. How is the weather there? Here is great but have no time.

[lenny]

Hi, How was your gig ?

Like I said we can make it work, Just need the right size hammer.
The weather hear is sunny and 45 f winds 20 to 50 mph, Just a little to much chop for testing.
I will be testing some more tomorrow to see if the 5.5 helped any and try some more props,
A X440/3 and grims 40 X 52/3 and a L40 X 57/3 and see what happens.
Than see how it likes 4s1p and 4s2p.
The last time I ran 3s2p the cells were all the way back to the servo stand and my gps was next to the servo,
But than it flip and got wet.
I put more seal around the hatch, So I will have to test that to.

[tlandauer]

The gig was OK, one more tonight, then a new set of program starting tomorrow Usually it is rare to have back to back schedule like this, that means can't go to the water
Sorry to hear your flipped boat.Hope everything dried up. I am not as disciplined as you or other members when it come to ajusting COG, I put my GPS infront of the motor when I checked the speed, I know it is laughable...

[lenny]

What every works for you with the gps, I just had room their.
Ok some good news and bad news.
The bad was,
The hot glue I used on the motor mount,
Got hot and it was coming lose at the end of the last runs back to back of the day.
Good news, The 5.5 made a big difference in temps and power on 3s and 4s.
The hatch seal was water tight when I tested it,
I ran on 4s2p with x442 and gps a 38 mph, Than 4s2p with a x440/3 and gps at 39mph and it ran better.
Hears some video on 4s2p 30c 5800mah packs with the x440/3 prop,

What do you think ?

[tlandauer]

Like I said: Lenny, looks fab! You really dialed her in. The rudder makes a huge differance. I don't understand the hot glue part. I was always afraid the temp on the motor mount would eventually make the epoxy and fibre glass brittle.
Your speed is really good for the P1, I don't think one can push too much further plus the scale look makes her look real good on the water.
Funny you posted today, was just going to say that I decided to ask you how you modified the stock trim tabs, I don't want to do the mod on this hull, think I will do on the other one that I have not used. Easier to take things apart and I like to use the trim tab w/o the bent down part---think you might have cut them.
Anyway, I am in for a real busy spell---guess that is good for my fleet If you don't mind I will ask more questions regarding the material you used for the off set arm, etc.
thnks

I was out of epoxy so I grabbed my hot glue gun when I had to fix the stock motor mount and bolts that were stripped out,
It worked on other stuff so I thought why not.
But not thinking how hot outrunners are with no water cooling,
So the glue started to get soft again from the motor heat, You can hear it in the last run I made.
Trim tabs I took off outside screws and than inside adjuster bolts, But you need to take the wood out to get to them.
I made my wood removable now with wire ties and a brace for them to go though.
Than I flatted them with a vise and hammer and sanded and polish them,
The offset bracket is 5/64 aluminum and you will need 4 new bolts, Two of them tapered with lock nuts.
When you are ready I will walk you though it.

[tlandauer]

Thanks, off to rehearsal! Also I think the 5.5mm plug is a real good idea, I have that on my ESC batt. leads but the motor i left them with 4mm, maybe I should up grade. I can't believe you really used hammer to flatten them, looks smooth! Thought you grinded them off.

[lenny]

I see you got some new boats,
The little hydro should be fun.
I have a mini bolt that runs on 3s and is really fun.

[tlandauer]

I forgot to tell you that the T500 motors came from Fightercat, nice motor but the diameter of the thin rim which the motor clamp could grip is larger by 1mm, still have not got time to try. I then also was wondering since you can mount that motor the regular way, it fits on a 4074 motor mount (OSE-80600), if one were to rip the stock mount out, can that set up work on the hull? I noticed how low the stock motor "sits" in the clamp, the 4074 is a bit higher. Still, this mount has water cooler and the fiberglass mounting will not heat up the hull like the stock mount.
Any thoughts?

[lenny]

Yes that motor will fit in the stock mount, That motor was in mine when I got it.
I Just had to fix the stock mount and see how it ran with the stock motor,
And yes water cooled mount is nice and will work with a little modding.
Boat on water heat go,s through the hull,Just a transfer factor.

[tlandauer]

yeah, I know, as long as the boat is on water that is fine, I worry when I take it out to change batteries or temp the motor and ESC, have you touched the legs of the clamps?! it gets hot and my motor's front is the hottest @ 150* or so. Which Kv do you have? 1600Kv or 2200Kv?
BTW, your Bolt is quite fast at 30mph! I think my DF Mini Hydro RTR is at high 20's, but it sure is fun, it has a BIG turnfin.

[lenny]

I have the,1600, T1800, 2200, and t600 1400kv,
My temps are getting better on the motor 135 f.
You should try a x440 prop and the 5.5 to on the motor.

Thanks I just did some mods to the hydro and need gps it again.
