Hello Markus need a little help. I am going to fit the 3 motor setup with v mixer. I Have three questions if you could help please.
1. I am not all about on servos. What is a servo notch and where can I find it?
2. On the 4 channel setup you show 1st turret ESC on CH3 and 2nd Turret ESC on Ch4. Where can you purchase these items?
3. Also shown is 1st motor ESC and 2nd motor ESC are they also required?
Matt

Matt hi matt ! 1. the notch is located inside the servo - it's a mechanical 'stop' for the end positions 2. if you mean ch3 and ch4 - these are just the outputs of a 4ch receiver. a 2ch recevier doesn't have them, so you need a 4ch transmitter, too if you mean the turret esc's - these are tiny 4amps forward/backward esc's. you may get them in a model shop or i'll get them for you 3. these are just the 'normal' esc's for the prop drive. they're needed if you want to run your ship on a pond markus

Thanks for the information Markus. I will have a look next time I am up town in the model shop otherwise I will let you know. Once again thanks for your help.

Hello Markus. I have managed to find two esc's for the turrets thanks. This however raised a question.
As my power to the receiver is from the electronic speed controller number 2 in the 3 Motor setup the red wires cut feeding no 1 and 3. My question. In the 4 channel setup drawing should the red wires also be cut feeding the 1st and 2nd esc from the receiver?
Thanks
matt

Thanks for all the help Markus. Looking forward to the fitting of the radio equipment in the near future.

hey markus, I was just wondering... instead of doing lots of difficult modifications to servo's by adding new wires and switches etc. ... wouldn't it be a easier, more reliable solution to use a flap dial from a model airplane transmitter? ( talking about 2.4Ghz here, 35Mhz is illegal to be used for boats) this is some sort of potentiometer and can be used to turn the servos... the only problem that will occur is that the front and back turrets will point in different directions, but this can probably be solved by turning around the + and - on the rear servo's...

The servo normally only goes 90 degrees. The mods Marcus has done extends the swing to the 270 odd degrees needed for a gun rotation.
You need a servo reverser gadget to reverse a servo. It's not a simple case of swapping the + & -. That would just wreck the servo. You can get a Y lead with a reverse built into one of the legs which would do the trick.

a flap dial will work, but the servo simply follows the dial so the turret's movement might be too fast. also i don't even have a spare proportional channel servos can only be reversed if you swap the motor's AND potentiometer's terminals - otherwise damage like mark pointed out the transmitter's servo reverse switch will do if you use 2 channels for the turrets (anton/bruno normal - cäsar/dora reversed) markus

What about the servo reverse, that is on some transmitters. Well spotted Sky You used to be able to buy left left had and right hand servos, but they seem to have died out now nearly all transmitters have a reversing switch. (or at least become difficult to get)
