Microgyros, you are indeed correct I did miss out some information not intentionally just lack of understanding on my behalf......
Inertia I didn't realise that about gel cell batteries, I assumed a big bulky battery would have more to give than a 10 pack of nicads....... Again just lack of understanding on my part.
So, a 10 cell NiMH for the brushless motor connected to the ESC. this is then plugged into the receiver. So far so good
Now then I have 4 sail winches, they have a working current of 0.3a to 0.35a and a stall current of 0.86a to 1.05a. Is the suggested separate battery pack per servo or enough to power them all for a decent sailing time?
The reason I am trying to avoid Lipos is because I want to charge my batteries whilst still in the model and I don't like doing that with Lipos! There may be a lot of space in the hull and 3 openings but 2 are blocked by servos and the large centre opening will have strings in the way. (Although if needs must I will fit a removable lipo under the strings) I'm just trying to find the best method to suit my situation and preferences. I'm beginning to understand and with all your help I'm sure I'll get there. Thanks!
Netleyned you are quite right it is only a 'get me home motor' for my 'Alantis' so why a brushless. Well, when I started the build I had one in my workshop sitting there doing nothing. It was shiny, new, and got designed into my plan. I am learning as I go along (especially with boats) that just because it's a more modern invention that it isn't necessarily better, but it's been built in now and I don't want to start changing what's already been built. That's why. That's also why I ask all these questions now so that next time............ U2
