Mark,
SubCommittee member Dave Welch has hands down the nicest example of this boat I've seen, and it runs great. Spent a good bit of time admiring it at the SubRegatta last weekend. A beautiful piece of work.
SubCommittee member Mark Jones is one of the "specialists" in tiny R/C sub conversions. Amazing stuff.

I would suggest that you check with either of them on the subject.

Best Regards,

Jim Butt
Membership Chairman, The SubCommittee

I've posted some shots Dave

I've posted some shots Dave sent me of his upgrade of this Dumas kit on my website under "Other Guys Projects". SubTech will be selling the upgrades as an option along with the actual kit.




Here is what Dave told me -
"Hi Tim, I just wanted to send you some photos of my new Akula. It is undergoing sea trials now. I started with the Dumas kit and just used the basic hull. I wanted to see what you could do with a inexpensive kit like the Akula and add more detail. You would not know it is the Dumas kit. I molded up my own scale tail planes and tail cone extention. I also molded in the raised hump on the rear deck. I used their basic WTC also but changed it to be more user-friendly, and installed a gas ballast system.

It has all Subtech seals in place of the Dumas ones to. I ordered the scale prop from Germany. I had 90% of the Dumas parts left when I was done but it is still a cheap way to go, for someone that has more time than money. I wanted to show what can be done.

I have a few bugs to work out but it looks very realistic in the water. Skip has my masters now and is planning to sell a retrofit kit. I just thought maybe you could use the photos on your web site.

See you at the SubRegatta, Dave."

Mine is 90% completed and

[color=#000000]Mine is 90% completed and still under construction.
During construction, it would be wise in cutting and trimming hull CAREFULLY!! i'm working on fixing hull gaps.
If you hold off construction, theres scuttlebut that in the next issue of TSR will be an article on building the Akula. If you don't want to wait. MY advise]

I just orderded one of these as my first sub, and I was curious what type and size battery to use. Will sub C nicad's be good? And what size motor does it use? Thank you for the help

[color=#000000]Frank,

I built one of these over the winter. The plans call for a Dumas 6 volt motor (model 2004) set up in a direct drive configuration. It is my understanding that this motor is a bit pricey. I used a Graupner Speed 400 coupled to a 3]

Does abyone use brushless motors

Does abyone use brushless motors in their subs, and would a 540 size motor be too big to fit in the sub? I know it would be too much power, but it would give me even more run time. Thanks for the help.

if the r/c sub could

if the r/c sub could run for more then 2 hrs., you may have to make a bigger battey pack for the transmitter.
don't over kill, with the brushless motor, on your first sub, things should be dry Will get wet! [one smoking speed controller for sale ]

brushless motor are not cheap.

still try to finish the dumas bluefish.
