My 1st post (with many questions) - Engel diving systems

[color=#000000]Hello to all,

I'm in the "planning for kit purchase" phase, and have decided on the supplier]

The navy version is an option but i don't think that with such a long boat the effect will be noticable. If you go with the normal tx you can always choose to mix the rudder and esc's by means of a mixer. You'll have to use to esc's though.
I can always recommend 2 esc's because of redundancy. If one breaks or the prop becomes entangled with weed or anything like that you will still have control over your boat.

About ballast control. I don't know the Engel system but I know of a plan in Norbert Bruggen's book available at Modeluboot.de for a fully propotional piston tank.

You can also use his controllers for the depth and pitch control of your submarine. That way you have and alternative. There is also subtech, a guy named Nils Canditt (I have one of his) and probably more suppliers of depth controllers. I think they might even be cheaper than Engel.

Hope this helps.

For a mixer that inputs rudder and throttle and outputs to two different esc's and rudder where the rudder is assisited by the esc's check out this sit.

Erik,

Thanks for the replies http://www.subcommittee.com/forum/icon_biggrin.gif

Erik,

Thanks for the replies especially the link + idea of the mixer, I like that concept.

I think point about the length and narrow width of the ship degrading impact of seperatly controlled screws is vary valid though. I'll think I'll stick to simult. control in my Phase 1, can always add a mixer later. I do wonder though if a mixer could result in a change (improvement or degrading) in high-speed turn behaviour in terms of yaw (think thats the term... I mean keeping the conning tower and rest of the sub 'straight' up) stability.

As for the alternative pitchcontrollers and diving systems, i've investigated many of them but engel's seems most appealing (and price differences arent that enormous compared to the total initial purchase cost of the kit), I know I want one of theirs , just am wondering which one cause I dont want it to be so over-automated that certain manouvres become impossible , hence the info request . My main concern is the 4-position system, it is unclear to me if those 4 positions (surface, dive, hover, park) are fixed or proportional in the 'between positions' (want to be able to crash dive but also to make a 'slow' decent for example).

I'll join the subcommittee as soon as I've ordered & receive my kit, seems like a excellent source of info .

thanks again for posting!
