G'day everyone

A mate of mine has given me an Anderson Sintra boat to fix.
It is a Sintra 700 twin power model; all I've found so far is they only seem to be available in Europe.
Anyhow, It has 2 x batteries, and 2 x motors driving a single prop.
The micro switches are no good, but I do not trust the way it was wired in the first place. Does any one have some info as to the connection of the 3 x micro switches??
The throttle servo has a cam on the horn
Reverse uses 1 x switch, forward uses the other 2 x in combination.


Please help!!! [][][][&o]

g'day mate!

i assume you're referring to some sort of mechanical speed controller right (MSC)? i've tried a few, but really i think you're better off using an electronic speed controller (ESC). That way you'll get much smoother throttle response, and some MSCs do seem to cause problems when they get dirty and don't make proper contact, then power kicks in all of a sudden etc.

You can get reasonably priced ones on ebay

110A should be much more than enough for both motors.

Thanks, but I'm not about to re invent the wheel with this clanger!
I just need to get it working again.
Anyone????

The sintra 700 and the caribbean cruiser are similar boats. The micro switches setup for that boat are heavy and have alot of resistance as appose to a good electronic speed control like the jeti navy 600. A good 12cell esc will allow a few more mph with out a motor upgrade. I will try and get back to you with the wiring info.

Thanks, mate; that will be a big help. My buddy just wants the boat to go,
when he's tired of the pace, maybe then we'll think about beefing the ol girl up, or going to another boat altogether.

Cheers

Can anyone help out here???? I just need to get the boat back together, and get it out of my hair!!! God knows, I have enough RC stuff of my own to keep me BUSY!!!!

Mudgy place a fax number in this post and I will try to fax the wiring diagram for the micro switches.

Mudgy Emailing the information via email maybe easier for me to forward the information to you. Whats you email address?

Mudgy

you can PM me - I checked my profile, and it's there


thanks

Mudgy I scan the info on to my computer but I cannot get the info forwarded. Thanks for your cooperation.

Alright, this much I'v'e worked out myself....reverse and forward, only need one or two batteries in PARALLEL.
I read too much into it thinking series/parallel. The forward switches are single throw, single pole (hence the need for 2 x to change motor polarity).
Reverse just connects motor negative, using the N/C of one of the forward switches to complete the positive side of the circuit. ( I knew the ol' sparky in me would come out eventually)

forwards is a reverse polarity set up ( like a power windows switch, duh!)
So if just one battery is used, same results. 2 x batteires (and 2 motors) is always better than one, right????

So, after throwing away lots of scrap paper, I have come up with this. Just so no one has the hassles I had.

Mudgy what is can tell you is the first speed is the 2 packs in parrallel and the second speed switches it to series. When you are wiring the switches keep that in mind. Also the switch that is single by its self is nomally on so when the servo is in neutral and set right it clicks that switch to break the circuit. When the throttle is advanced a bit the servo arm ease off that switch and connects the circuit to have power flowing from the supplied packs or pack, when advanced some more the two micro swithes are connected to cause the packs to be in series. You should be aware that is setup is good for 15amps above that you run the risk of have the switches damaged. Therefore your friend don''t have room for much up grading with the speedcontrol.

I gave the boat back to my mate wired the way to my diagram. Reverse and forward uses parallel only, and 1 x or 2 x batteries can be used. I think this will do for bashing.

thanks.
