Re: OTW NACKEN BUILD HMS Neptun

Getting some glitching on my servos. How would I add capacitors to this motor?

Re: OTW NACKEN BUILD HMS Neptun

Heard of X2Y components? Basically a balanced capacitor network designed to reduce EMI. Heavily used in the automotive sector for suppressing brush noise. Works better than three caps, and will be a snap to install in a motor like that.

You can get them from Digikey.

Have a look at this for information about how they work and how to fit them-

Three caps should also be fine wired as close to the can as possible. Inside the can would be best and looks tidy, but more tricky to install. SMD caps are very small 1206 components are easy to solder with conventional sized soldering kit.

I see that Mouser sell them too, probably a better bet if you only want a handful.

Thanks Andy... I will look in to them...

Still trying to work out the electrical glitching.....For now, I'm working on the hull seam.

Re: OTW NACKEN BUILD HMS Neptun

what seam?
that looks damn near perfect!

Re: OTW NACKEN BUILD HMS Neptun

I'd say it IS perfect—at least that corner. Wow.

Re: OTW NACKEN BUILD HMS Neptun

Unacceptable seam. I think you should keep at it until a scanning electron microscope is the only way you can identify it. LOL You have done an amazing job on this sub.

Re: OTW NACKEN BUILD HMS Neptun

Looking at your work here and others that you have posted.

I should just quit. Give all my stuff away. Start saving money until I can afford just one of your projects when it comes up for sale.

Re: OTW NACKEN BUILD HMS Neptun

Thanks guys. Just takes a few extra rounds of bondo and sanding. As for future projects, several targets are on deck after these 2 are completed. A high speed tug and jet patrol boat of some sort.

Re: OTW NACKEN BUILD HMS Neptun

Just finished up the control surfaces. Nice and smooth and no binding. Does anyone have a source for the double U joints that can handle more than the Dumas dogbones? Need it for 6mm.


Thanks,

Re: OTW NACKEN BUILD HMS Neptun

Maybe these stainless steel universals can be used.
Stainless steel universals
They are not expensive and look as if they could be made to work.

I have seen your boat in person and I do believe you have room in the hull to have a mechanic maintaining the equipment.
He price is right.

Also might look at these couplings Look at the Universal Couplings.

Re: OTW NACKEN BUILD HMS Neptun

Thanks Ralph. I do have 2 of the stainless ones in the mail. Will make a double out of them and see how it works. The Lovejoy couplers have too small of a misalignment tolerance. I can get it aligned well but with the large hull, the flex makes it bind terribly. It needs the double unit.

Re: OTW NACKEN BUILD HMS Neptun

Your building skills this issue will be over come making everyone else look like the amateurs we are.

You work is so clean and well placed.
Thought and execution as you build are a very high standard to duplicate.

Jealous..no...envious yes.
