Happy New Year to you and Ellie!!
Am finally, once again, able to get back to my little Skipjack, after 95 feet of post-and-rail fencing!
But, "She-who-must-be-obeyed" is very happy! Hah!! One less project on the ever-increasing length of the "honey-do" list. Life is good!!!
Ennyhoo, with regard to the aft dive planes, it appears that the hole into the planes themselves needs to be in the neighborhood of 1/4" to 5/16" deep???
Hope 2014 is a good one for you!!
Party on!!Comment

Many thanks, once again, M!!
Your help is greatly appreciated!
Happy 2014!Comment

Master "D":
After much sanding and fitting on my little sub, I finally got the upper and lower hull halves to line up pretty darn nicely!!
Got primer, and will soon have "real" color!!
I'm starting to figure out the sd assembly, and have a few "assumptions"!? Please interject as needed!!
First, the "flanged servo box" lower cover interferes with the sd's ability to fully seat into the lower hull half. I'm assuming that if I remove the flange, and make it look like the "servo tray", that all shall be right with the world!?
Secondly, the depth at which the "servo tray" is to be anchored should be a "few thousandths" short of the bottom of the cover!? The close, the better for the magnets to be able to do their job efficiently!?
Lastly, it appears that the "ears" on the little linear servos need to be removed to allow placement of two of them, and also be mounted to the tray with a dab of silicone!?? Just made sense to me, but I digress!!!!!
Your 4-1-1 is, as always, much appreciated!
Thank you, M!!Comment

Bevel the longitudinal edges of the lower servo box cover till you get clearance with the hull.
Test fit the servo tray with the servo's made up with their magnets, put a piece of masking tape over the magnet -- this acts as shim to get that little bit of clearance between the top of the magnet and the bottom of the upper servo lid. Test fit the servo tray and upper lid till the lid makes contact with the magnet. Once you have that worked out, CA the servo tray in place.
When you chop off those servo ears, you'll have to bridge the board where you loose continuity -- hello micro-soldering. This will test your metal, pal! I mount the servo, via its micro-processor chip to the servo tray with CA.
Go get 'em, Tiger!

Copy that, M!! Thanks a bunch!
So, "micro soldering" you say, eh?? Oh. boy!! I knew there wuz gonna be a "bit of a challenge" somewhere!! Hah!!
Fortunately, I had picked up on one of the "Iso-Tip" soldering pencils a while back for my model railroad work! Great little unit!
O.K.! Off to the drydock, as soon as the first blast of caffeine kicks in!
Have a good one, and thanks again!

Oops!! One more time, M!
I would think that the servo box covers should be secured with silicone, so as to allow for removal, if needed?Comment

M-
Another "grasshopper" question, if you please.
Is there a rule-of-thumb as to placement of the SD electrical components so as to avoid any possible interference among them?
My inquiring "newbie" mind would like to know!!
Thank you kind sir!Comment

And yet again, Dave!!
How necessary is a LiPo safety circuit, and what exactly is its function???
Muchas gracias, Jeffe!! (LOL)Comment

Not vital to have it on board, but if the Lithium-polymer battery voltage drops below a critical voltage, you kill the battery (or reduce its capacity). If you run the thing with a 900mAhr pack and keep your run time under 30-minutes, you're good between charges.
The function of the thing is to kill one of the r/c channels aboard the model submarine -- in this little thing I put the Lipo-Guard in series with the stern plane circuit. That way, when the thing senses low-voltage I loose control of my depth keeping ability, telling me time to come home for a battery swap.

Hi, M!
I figured out a pretty easy way to avoid the "micro-soldering" regarding removing the mounting ears from the little linear servos. Hopefully, I'll actually be able to attach photos of exactly how I accomplished this!!?? (Film at eleven!!)
I removed only the mounting ears that don't need to conduct power! Fortunately they're both on the same end of the servo.
After determining the depth for the servo tray, I Dremeled out a couple of little pockets, in the sides of the servo box, to allow the remaining ears to recess into them. (See the red marks??) The servos are then acc'd to the servo tray facing in opposite directions, so as to have the linkages as close together as possible.
Seems that this will work out pretty well!!
Thanks, again, for your ongoing assistance and support!!

Holy frijoles!!! Ah dun it!! YEEEEhah!!Comment
