James bond lotus submarine

[ffr2608]

Motors mounted up and bonded to the hull. Decided to go analog from this point forward. Acrylic, brass, stainless and styrene. I did find some old Subtech SBS seals so I will be mounting the pressure box tomorrow.

I used to pass these out to the Gen X engineering teams with the poorest performance, with the admonishment, (can't go full-on Master Chief on them or they begin crying spontanteously) "Of course this is hard, that's why we hired you. Turn around. Do you see a line of people behind you trying to do this?

The Easy Buttons were a daily reminder that difficult jobs require extra dedication and effort to complete, not well-meaning intentions.

Talkers and quitters exist in every arena where work needs to be accomplished.

Not just this thread, but nearly all 'look what I'm building/assembling' threads are false starts; fools errands that just waste our precious time. Usually launched by unexperienced, untested hobbyist who have no idea of the long-term commitment, knowledge, tools, and shop skills required to see the project through to a successful conclusion.

Before cluttering up the forum with your high expectation/low performance posts read Bob's book first!

FIRST: Buy "Diving Deep - The Beginner's Guide to RC Submarines"
I created this book to help answer many of the fundamental questions that people have about this amazing hobby. Available in digital download or hard copy , it can answer many of the questions that you might have. DO NOT reach out to me or anyone else if you haven't purchased and read this book!

Most of you idiots have the attention span of a Goldfish; you all hardly have the patience required to yank a foamy airplane out of its box and toss it into the air.

R/c submarining is a deferred gratification game; you are required to put in many, many hours of planning, assembling, testing, trimming, painting and shake-down.

But, let me make this clear: the above rant does not apply to people like Darrin Hataway -- guy's like him are pro's who GET THINGS DONE. Unfortunately -- and this is true to all forums that deal with Craft -- the guys who actually see a project through to completion are way outnumbered by those who start things they never finish.

I get your frustration, and I share it.

Any news?

Please don't let this become another build thread that suddenly stopped. There's been at least one if not two 007 Lotus build threads that simply fizzled out.

That is possible but will try to get it all in the box. I could also add the low-profile s3 box to place the battery separately. Not ideal but possible.

18650's in the wet?

[ffr2608]

Brass sleeves for the dive planes are in. Plenty of room for testing and motor placement. Dry box is going to be a bit tight so might need to scale the battery size back.

Differential thrust with sliding weight for pitch control.

Yeah, I remember that. Pretty impressive.

ffr2608,

Nice Swift Boat! Very much impressed with boat operation and the great sound system! Thumbs up all the way, and thanks for sharing.

Good call Andy. I have had good luck with some non-sensored on a boat but a couple brushed can motors would make things super easy. I prefer dry electronics over "in the wet" any day.
This is my big PCF using mixed throttles on the left stick. Very easy to dial in the steering with a computer radio.

I could use some help on this because there are no brushless dual esc’s available out there.

If you're going to use differential steering with brushless motors, then I'd look for some esc's that have a very smooth startup.

You can use ESCape32 firmware on some blheli32 esc's if you're not squimish about burning a bootloader and firmware. That gives the esc's a rock crawler mode, so super smooth start-up like a sensored brushless motor or brushed motor.

Ideal to precisely shoot a helicopter out of the sky.
