today's work

[Monahan Steam Models]

Structurally the only assembly work left is the sail and to integrate my 'fitting kit' control surfaces and linkages to the hull. Part of that fitting kit is the foundation to which the 1.25-inch FPV enclosure resides. I'll spend tomorrow working up the next installment to this thread -- mostly dealing with how the camera-transmitter antenna is replaced by a length of coaxial cable so that the transmitters antenna can be placed high atop the periscope.








Film at Eleven. I'll show things off during Saturday's Zoom meeting.

It’s looking really good. Nice work. Look forward to Saturday. Should be a fun boat with the new camera gear!

Can I join your meeting?

Not my call. Sign up with Bob.

How’s the type XXIII coming along?

Oh, ****! Sorry Andy and Bob. Pulled the trigger too soon. Thanks for the catch, Nick.

Too big for the cylinder. Thanks for the tip, Bob.

Very nice work and it fits like a glove!

Couple quick questions. What effects have you seen with these camera enclosures on the ballasting and stability of the model? Are you going with a snort system or S.A.S? And finally, are you planning on using a ghz or MHz radio in this build? Asking because of the model only having the single periscope where normally you can hide the antenna or snort intake.

Looking good Pal!

Overall submerged trim is as before because the enclosure (which is well above waterline in surfaced trim) weights as much as the water it displaces. However, the extra weight of the system does make the models surfaced freeboard a bit lower than scale. The added topside weight also contributes to a slight de-stabilization of the boat about the roll axis. But I always go over-kill with the amount of fixed ballast weight I stick in the models lower hull.

SAS. Only because I built this SD over ten years ago. As this camera mule will spend most of its time at PD I could have gone with current fad of 2.4gHz for the r/c system. And that is not a problem with the current FPV camera-transmitters as those operate on the 5.8gHz band.

I'm going with 75mHz gear as I plan to dive and work out a means of recording the video on board to a mini-SD card. That way, when the cameras transmitted signal is lost at the ground-station (say, I see a target I want to chase that went deep), I still have a complete camera record which I can pull from the mini-SD card later.

The 75mHz antenna will be down in the hull.
