TOPIC: Acoms techniplus 2 ch.

Acoms techniplus 2 ch. 1 year 2 months ago #51091

I am new to this group and a total newbie.
I have built many model ships incl the Santa Ana spanish warship, took me 4 years.
Also built a full working scale Minnie tractor engine which works with steam.
Just taken charge to sort out a Smit NV tugboat.
All in reasonable condition, a few repairs to the mast etc but is in good shape.
Estimated age of the model 20 years.

Ok, I am new to R/C.
It runs with a 12V 7a/H battery, I am replacing, should arrive this week.
The original battery would not take any charge, its a sealed acid type.
The battery has a direct link to the 2 prop motors and then into a M$ sonic marine box.
This box ?? has heat sink vanes and a SET button.
1 (3) wire ribbon cable goes from this box to the Acoms 2 channel receiver.Plug Ch2.
This receiver also has a 3 ribbon cable to the steering servo.
There is a 3 rd plug socket for BATT.
Question, as I do not think anything is missing, do I need to supply power to the receiver, or does
power come from the BOX to make the receiver alive.
I see some need a 4 x AA batteries and a on/off switch.
I do not want to power up and have things go wrong.
The hand set is a Acoms Techniplus 2 ch.
What do the 2 switches marked R N do.
Sorry again for asking silly questions.

Welcome John,
You need to connect the 4cells to receiver. A receiver works under 4,8 to 6V.

Many thanks.
I have a battery pack holder and switch on order, as a back up if the receiver does not
see voltage from the ELS?
Seems a mystery that all the bits were in place but not battery holder.

I will keep you informed.when the new battery arrives.

Thanks

John

Your techniplus should have bec system but if the power source send more than 6V, il could burn the receiver. The bes t if you have a doubt, put the batt holder on the receiver.

Thanks

Reading up a "bit", that would mean cutting the red wire in the 3 wire ribbon from the BEC " what does that mean, life is full of acronyms.
Then connecting up the 4 x AA box to the vacant plug hole.??

No! Don't touch to servos wires. BEC = battery eliminator circuit. When you use a ESC or classic MSC (variators), the bec system included in the receiver avoid the use of a dedied battery. But you, from what I understoud, you use a 12V batt directly. So you need another batt to avoid to burn the receiver. If you had a gp system, you need a battery for the receiver. You maybe have a too high voltage with a 12V batt.

No, the battery goes first to the MSC (BEC) also paired off the the 2 x motors.
I will send some photos
Best send me your ( if possible your email address), I can send direct a bunch of photos.
I truly believe we are on the home run, looks like the BATT female in the receiver has never
had a plug into it, also when I received the boat, there was no 4 x AA battery pack or switch.
Best regards

Depending on how this M sonic marine ESC works or does it job you may not need an extra receiver battery. If it has a BEC it probably feeds the receiver with 5/6 volts. Photos and a model or type number and some Google or forum experts will probably sort that out ;)
