Fun With Magnets

[Ralph --- SSBN 598]

This I don't know.

There are some water based clear coats.
This discussion is going on on another board.

I have decided to go another way.
Because I am currently completely repainting the hull, which means I took off the decals and sanded down to the hull plastic white, I am going to use a good flat black.
Then apply the new decals when they arrive.
They I will do a test on a piece of plastic to see if I can clear coat just over the decal edges.
If that does not work, I plan to use a good auto wax and seal the decals with that.

I hate painting and I can't make a straight line or get tape to seal to make sharp edges.

I has resigned myself to possibly having an all black boat.

I am in the process of repainting the hull and have the bottom (below the waterline) looking good.
I may recover from this clear coat issue.

2K paints come in many different chemistry's- epoxy, polyurethane, polyester etc.

Usually 2k clear coats are polyurethane based. Extremely tough and hard wearing but lots of nasties in it, so an air fed mask is recommended if you're spraying it.

From what I can tell, acrylics are water-based and according to their marketing won't yellow as much as urethanes...just not as durable.

Not sure what urethanes you're looking at, but i was referring to the kind of stuff used in the motor refinishing trade. Those urethane clear coats won't yellow.

I once used a Dupont Imron system on a white boat and it yellowed after a few years...not sure about the chemistry though...

Be careful with the Krylon.

In my shop I have 2 cans of Matte Clear.
They are not the same.
One worked okay for me, the other blistered the paint right off a sailboat hull.

My problem is, I don't know which is which right now.
I guess I could make up a test piece and spray half with one and half with the other.

I just chose not to use either.

[Oldus Fartus]

Nope, that's not correct if I understood correctly.
Do not change anything to the UBEC connection. Just plug it to your Rx as it was a battery connection (+ and - wires).
It might be a mistake from Engel, you should not have received a 8455 but a 8454 instead. Maybe you should contact Gregor about that.
Anyway, if you decided to keep the 8455, you have to connect the two pins (where there should be the red and black power wires of the 8454) to the pitch controller and disconnect the red wire of the ESC plug that is connected to the RDD (use for example your extension cable between the two devices).

OK, I got the 8454 but it doesn't seem to invert the direction of the dive planes and the end point on the servo in one direction is very small compered to the opposite direction.
Both end points are set to 100% on the transmitter.
Any ideas as to what is going on?

I found this to be a bit of a puzzle.
I could not figure out how to reverse the planes.
Then a thought.

How does the boat know which direction it is going to reverse the plane deflection?

Answer:
You have to give input to the main motor.
First, give the main motor some forward direction. Very slow turns will do.
Now, lift the boat and pitch the hull watching the rear planes.

Bow up = rear planes down.
Bow down = rear planes up.

Change the main motor control to give slow reverse rotation of main motor.
Again, lift the hull and induce pitch on the hull.

Bow up = rear planes up.
Bow down = rear planes down.
------------------
I was not paying close enough attention the first time, that I missed it this happening.

I had to turn the main motor on forward slowly and pitch the bow up.
I watched the rear planes movement.
While holding the hull, I slowly changed from froward main motor to reverse main motor and saw the rear planes change position.

OK, so how do I get the throttle channel on a Futaba 9C to run the motor in reverse?

I've only run planes and helicopters with the radio.

[Ralph --- SSBN 598]

CAP 9 Tx.
start by placing the throttle stick in the center. Neutral.
When you turn the Tx and Rx on, the Tx should program the ESC to nuetral and you should now have forward and reverse.
---------------
You might want to go in to the Tx menu and make sure the Throttle stick is set to 100% in both directions.
Once you get both directions, then go back i and reset the percentages to about 30% to start.

[Oldus Fartus]

Hmmmm...the ESC will only program (red LED off) when the throttle is in the "0" or all the way down position.
If I start with the throttle stick the center position, the ESC red LED simply keeps blinking and never goes dark.
What am I missing?

[Ralph --- SSBN 598]

Sorry, there is more.
Turn on Tx and power up the boat systems with stick in center/neutral.
Then move throttle stick to full forward.
Pause then move to full reverse.
Back to neutral.
This should set the up and lower limits.

[Oldus Fartus]

That didn't work either.
Seems like I can only get the ESC to program "0" when the stick is in the lowest position.
This is the only stick position where the LED goes dark.
In all other positions the red LED is blinking until I move the stick to the lowest position.
Once programmed if I move the stick to full throttle the LED goes from red to green...not sure what's happening when that happens...the motor is transitioning from mid-range speed (LED is red) to high range speed (LED is green).
According to the Engel website the BL-30 controller can be programmed as Forward only or Forward-Reverse.
It looks like mine is programmed incorrectly.
So I went on line and found the supplier of the ESC (TecniModel) and downloaded the programming instructions (in French naturally).
Translated into English but still unable to change the Mode.
Still can't seem to get into Forward-Reverse Mode (not sure if it's 1 or 2)

[greg w]

parameter 1 is the running mode and it's two short beeps for forward and reverse, I will attempt to scan the manual and post it shortly

Was thinking on this.
Is your Tx set to PPM mode?
When I got my first Futaba CAP9, it did not work.
After talking to Radio South on the phone, he had me step through the menu and set the Tx to PPM mode and all was good for running boats.
---------------------------
The mode is displayed in the upper right corner of the screen. PPM
If not then try this.
Hold the Menu button down until the menu comes up.
Turn the rotating knob on the right side of the screen until it displays the second menu and Parameters.
Push the rotating knob down once.
Move down the list using the two up and down buttons on the right of the screen until you get to the menu item MODUL: and select PPM using the rotating knob.
Once selected, press the End button on the lower left of screen ntil you get back to the Main Screen.
PPM should be displayed in the upper right corner now.
