My guess is this is the one I saw in the Tower Hobbies scratch and dent section?

If no one else has answered, I can get those measuements when I get home this evening...

Don't think I ever posted this info...

...here's what I use in my boats that I can't add floatation to. My schooner and tug use the float/line marker to allow for snag and drag or lift and recovery. I use 30lb kite string attached to a cabin/hatch with styro under it. It is tied off to a hard point in the boat. This will mark and allow a recovery of the sunken boat. The schooner has a free spining thread spool of line attached to a floating cabin and the tug currently uses 30ft loosely coiled line (soon to be upgraded to a thread spool too) attached to the rear hatch.

This works as an insurance policy in the event the boat sinks....


I got a good start on the mods this weekend...and ran into some unexpected issues too. More on that next...

I got the fire monitor pump installed/plumbed, but the “Battle switch” is not working with it. I don’t know why it won’t work, but it shuts on/off very rapidly causing the pump to do the same. It’s not a defective switch because I tried both of the ones I have and they both react the same. So…I’m picking up a servo activated micro switch today to turn the pump on/off with.

I installed a micro servo to rotate the fire monitor with…but am unhappy with the 90 degrees of rotation…I will need to play with the linkage some more to see if I can improve on that.

The new turbo diesel sound board sounds really good and everything works great with it when combined with the old ESC, but for some reason it will not work with the new Viper 25 amp ESC.

The Viper ESC works great by itself, but when used with the sound mod, it glitches the motor all over the place. I tried 2 different radios/receivers and used 12v and 7.4v power and those changes make no difference. I use the Viper 25 in another boat with the Harbor Model Chris Craft sound board and it works fine…I don’t know why this sound board or ESC is giving me all the trouble.

I’m waiting on the new version of the smoke generator (should be in today) to try it out. Hopefully it will not follow the same suit as the other mods and work like it’s supposed to.

I’ll take some pics tonight and get them up ASAP.

Here's some info and pics of the components.

Here are progress pics.

First up building the micro servo/switch block to control the fire monitor pump. I've never done one so there may be an easier way? It came out looking/working really well.

Here are some fire monitor installation pics. I may need to use the sprocket chain drive that came with the monitor if I can't get more than 90 degrees out of the current setup.

I had to remove all the plastic port holes/wheelhouse windows. After 4 years, the plastic was very very brittle and shattered when I barely touched them. I will leave the portholes open for now and screened in the wheel house for better sound. It now has a tinted glass look from a stand off view...

Smoker pics...

The older unit (still in the unopened bag) is a full time on/off unit. The newer version has a chip added to allow variable smoke. It is wired to the motor input terminals. It can be wired directly to the power source and still be used as a full time on/off unit.

I'm thinking about a switch to give me the option of center is off, switch one way for variable, switch the other way for full power only.

Now all I need to do is figure out how to wire it?

It is in a 24hr wick oil soak right now, and I hope to bench test it tonight....maybe some video will be coming too.

This is how I did my switch. I also installed a filter on the pick up.

Millertime...I saw that thread and still think you did a great job...especially on the fire monitor...the roller switch is another way to do it...good thinking man...

I got the smoker “picnic bench” tested last night. I tried it with 12v and 7.2v both direct connect and motor “variable speed” connected, and here are my findings:

On 12v… full power this thing puts out a huge amount of smoke. Unfortunately when used as a variable speed unit the fan doesn’t come on and it doesn’t start smoking until over 1/4 throttle, probably closer to 1/3 throttle.

On 7.2v…full power it still produces a good amount of smoke…but the variable speed unit acts the same and you get even less smoke at all speeds.

Except for some rescues, I rarely run at high throttle. When slowly cruising around the pond, I won’t put enough revs on the motor to activate the unit or get any smoke.

12v produces way too much smoke for this little Atlantic Harbor tug at full output. So…for my tug…the 7.2v full time on/off setup seems the best.

It’s nice to have the variable speed option available in case I decide to use it in another setup, but for now I will be hooking directly to the power source with a dedicated switch, most likely under the aft hatch, for quick/easy access. I wish I had another “7th” channel to remotely turn on off the unit, but I would have to give up some other function.

Also of interest is that the unit I have leaks oil and even smoke in several place around the top of the box where the lid attaches…not enough glue? I ran a bead of liquid tape around the edge and over the wire connectors where some of the bare wire was still showing.

I got the unit mounted the boat but still have to install the wiring/switch. Pics will be coming in the next few days as I finish up things.

Maybe some of the excellent minds here can come up with a way to control the smoke output. End point adjustments on the unit would have been really nice…

Switch the little fan from a 12V unit to a 5V unit.

Tom...I see where your going with this, but I would also need the heating element to work at 5v for it to produce smoke at the lower voltage that I'm using...7.2v... how do I fix that...

I think I found a solution to my being able to turn on/off the smoke unit by doing it with a shared channel via a "Y" harness. So...when I sound the tugs bell (elevator stick up all the way up) a micro servo will hit a micro latching lever or micro push type switch to turn on the smoke. When I push up on the elevator a 2nd time, it will hit that switch again turning the unit off. So every time I ring the ships bell, I'm also turning on or off the smoke. Gee...ain't I smart...

Back to the electronics store to see if they have suitable switch...
