Q.E.D. 😊👍
That's the main thing - whatever you do or how you do it - Enjoy it!!
Apropos Normal or Reverse at the TX:- Terry is quite right. 👍
If I remember my history correctly the Reversing function was originally added many years ago mainly to accommodate the 'fly boys'.
It made reversing servos very simple when the confined installation space made mechanical reversing very difficult or downright impossible. For ailerons in thin wings for example.

Have fun with your boat JB, and don't forget to put her in your harbour with some pics / video.
All the best, Doug 😎

Doug, you were quite right. Mtroniks have sent me a new ESC, with no explanantion, but it works in exactly the same way as the previous one, as you said it would. So, I shall ignore the settings on the transmitter and just enjoy the boat! A lesson has been learned......

Thanks to everyone for their valued input. 👍

Hi John, regarding the rudder, the 'Normal' and 'Reversed' designations are purely arbitrary.

If you put a servo arm in one position on the servo, then remove it and place it at 180 degrees to the original position, the servo is reversed with respect to the original position. Try it with a spare servo and servo arm.

The Normal/Reverse options on the transmitter are only there to allow for variations in servo to servo arm location variations. The 'Normal' designation is somewhat misleading.

As far as the ESC goes, that is sorted by programming the ESC.

That's my 2.7p worth. (5 cents Australian)

Cheers, Terry

John, thanks for the info; but that’s not the case here.

Hi just a thought the VIPER 25 AMP has a BEC (Battery Elimination Circuit ) built into it and if you connect a power supply to your receiver as well to power from the motor battery all manner of thing can go wrong

No sweat JB 👍
Very curious about what Mtroniks have to say.

Sorry JB but,
Total waste of time and postage.😲
1. The Mtroniks ESC and your TX appear to be working as advertised.
If you arbitrarily reverse the servo output at the TX then you must tell the ESC that, i.e. go through the Mtroniks setup process again.
2. if the whole thing works just fine with the servo reverse switch on the TX set to reverse - so what? Why mess about and waste money?
There seems to be no particular standard for what is 'Normal' or 'Reverse' between manufacturers.
I have noticed this phenomenon with several manufacturers.
In particular between older 40MHz sets and 2.4Gig sets of recent Eastern manufacture.
I just set the TX switches so that everything works the way I want and 'Bob's yer Uncle, Fanny's yer Aunt'. I really don't care if it's 'Normal' or 'Reversed' - "If it works - DON'T FIX IT!!"
Whatever, I would be MOST interested in Mtroniks response. I don't believe there is anything wrong with the ESC.😉
Please post their answer 👍
And yes, I have several Viper Marines in operation with no problems. Just follow the instructions as John posted above, and IF you change anything at the TX - TELL THE ESC!!
Good luck, Doug 😎

Mtroniks requested I return the ESC to them; which I did this morning. Will keep you posted.🤔

John, I have only tried the boat once on the pond for a fairly brief test, so I haven’t really tested the range. I have dropped a line to Mtroniks to see if they have any ideas. in the meantime I will continue working on completing the build!
Thanks to you and the others for all your help; I will keep you posted as to the outcome.

Ganz recht John,
Absima is a German company, just up the road here from Munich. They are specialists for RC Cars.
I have some of their LiPos but that's it. A lot of their RC gear seems to be just 2 Channel, gas and steering only.
A few 3, 4 & 6Ch sets, presumably to appease the truckers & co with lots of lights and horns 😉
Grüß aus München, Doug 😎

hi ya, I have just been reading up on your transmitter and it looks as though your transmitter was originally made for cars but it doesn't make any difference. Apparentlyit is a 2 channel transmitter which is supplied with a 3 channel receiver. Therefore when you plug the speed controller into channel 3, it isn't going to work. So the way you originally had it set up is the only way to get it working unless you go for a different transmitter.

What is the range of these transmitters? because I have one myself which is a Planet 2.4 Advance T5 and its got an extremely short range because its called a park flyer - I am wondering if yours will be the same just for curiosity. Best of luck.

Hi J have a look at these files it may help out 👍

John, I followed the video exactly, using ch.3 instead of the ch.2 recommended with the radio gear, but then I could not get response from the esc. Mine is a 25amp; would that make any difference?
I then switched it back to ch.2 (having already reversed the motor leads) and ran the setup again. The throttle now runs in the right direction, but if I switch the trim to normal, the motor runs at full speed forward. Switching it back to reverse, it functions normally.
What am I doing wrong??

hi ya J that looks like an Mtroniks speed controller in the pic - does this one have the button on that you press to set it up? because I know what you would need to do is set your trim in the neutral position for the throttle and then go through the procedure of switching on the transmitter and then the receiver and then pressing the button on the speed controller so it recognises where neutral is. I believe some of these Mtroniks are something like 100% rpm forward and something like 75% rpm in reverse. if this idea doesn't work you could always swap the wires over on the motor. (NOT ON THE BATTERY) 🤓 Chinee smokey come out of speed controller if you do dat 😲

Whilst I am not new to boat modelling, I am new to r/c and I’m confused about an issue I have.
You can see the setup in the images. Everything works fine, and testing the boat on the pond; I was very pleased how she ran.
The issue is this: if I set the trim switch (bottom right on transmitter image) to reverse, the rudder works normally. If I set it to Normal, it is reversed.
If I set the throttle trim switch to normal, the throttle is reversed, and if I switch it reverse, the motor runs a full throttle, with the joystick in the neutral position!
All the other trim controls are in the neutral position, as in the image.
I have double checked all the wiring, and would really appreciate some help on what I am doing wrong.
Cheers,Barry
