Gordon,
I never really found many limitaions I could not work around with the older 72mhz system, although some of the limitations did seem a arbitrary.
The new unit has rectified many of the limitations that preceded the 2.4 unit, you can now assign any servo to any channel... Even drive a single servo by multiple channels. You can gang any servo, regardless of rx port and even reverse a servo when ganged and sync'd. Still playing with the features but have yet to find a limitation period...
Well, I downloaded the s/w and experimented with it a bit... looks like it has the same completely arbitrary restrictions as the old stuff.
Not sure if I'm just doing something wrong with the s/w though, so as a sanity check - can you please try assigning Channel 1 to both Servo 1 and ANY of : Servos 9, 17, 25, and let me know if you can do it ?
So, I am NOT able to "assign any servo to any channel" as suggested above, due to numerous prohibitions introduced by the software. Feels kinda like trying to book a flight on NWA using airmiles - gotta keep shuffling stuff around and around to avoid the "blackouts".

Hi Gordon,
First off, sorry for the long reply. You are the one and only customer who has an issue with the servo assignment "limitations", as you put it, that Weatronic has in the programming. To me, how I understand it, it is safety and feature driven.
Tip: To avoid your shuffeling, you program first, then plug in the servos and then you can play without having to shuffle. simple as that.
The following is based on the 2.4 Dual FHSS system and the R series (big) receivers.
Initially, one can assign any servo to any channel with the first servo. After that, there are two (three for the 30 servo outlet version) blocked out servos which limits the choice of which servos you plug into which outlet for that same channel. The ratio is 2 out of 20 or 28 outlets initially? Now we have one servo per channel and voltage controller, which makes it the safest setup possible.
I will explain it to you again in detail now for the 2.4 system, since this is a 2.4 thread.
It is a programming limitation driven by a physical limitation as I have described to you in another thread. It is there for a reason. It is not "arbitrary or hap hazardous" as you like to put out repeatedly. We have a design / feature limit of eight servos per channel.
With eight voltage regulators on board, every one of them is limited to a certain peak and continuous load (peak X? Amps, continuous 32 Amps). To share the load of every servo starting (current peaks simultaneously) at the same time on a single channel you have to spread it out to the eight controlers. Else there is no point in having eight smartly sized voltage controllers. To achieve what you want, it would take 8 huge voltage controllers and cooling systems as a current Power Box system uses. Weight and space limitations and staying smart prohibits this.
Each one of the eight columns is powered by one regulator. With that said, "The Weatronic Gods" have two things in their mind.
1. They want it to be safer. If any servo on any voltage regulator dies and causes the voltage controller to be blocked by the draining servo, all other 7 regulators will still work fine and you can land your model safely.
2. "The Weatronic Gods" want to make sure that users do not overload the individual voltage controllers in the setup installation for similar reasons (see above). (During prototyping this has lead and would lead to future complaints from more than 1 customer)
This would happen if a customer like you who intentionally or not, ignores or is simply not interested in the safety potential philosophy behind this, would decide to put three high load digital servos of the left wing aileron of a big model on outlets 1, 9, and 17 (column 1) and the right three aileron servos on outlets 2, 10 and 18 (column 2). Now you do a fast roll or a rolling circle and everything reacts sluggish, because you are driving all aileron servos from two regulators at the same time instead of six regulators.
That is not hard to understand. This makes a lot of sense and has nothing to do with "arbitrary or hap hazardous God decisions" as you have put out.
If this is a "no buy limitation" for you, that is ok for me. The last thing I want is an unsatisfied customer. Luckily you have a choice.
Not putting in these safety features (limitations in your world) will naturally lead to complaints from the users that do not want to have to think too much about this sort of a problem.
The choices are:
- One or more crashed customer models which are then very unhappy past customers, with damage to someone elses property etc. etc. or...
- One customer (YOU in this case) with no sale due to a non functional "limitation" of choices of outlets over all the other features...
go figure - I will rather not satisfy you and keep the other customers who can live with this "limitation" safe and happy.
I will let the other customers vote by making their choice of weather or not they want to accept such an insignificant (my personal opinion) "safety driven mechanical feature limitation".
Sorry that we can't serve you in this one point.
Also please put out facts and not ambiguous expressions as "numerous prohibitions introduced by the software", because just the opposite is the case. No other system offers so many useful new and never offered features.
e.g. Show me a system where you can make a choice between channel and servo failsafe. I could go on and on.....
It leads me to wonder weather you have an agenda going against Weatronic driven by???
No offense, I really hope this satisfies your questions and sorry for the long detailed reply.

P.S. Good luck if one of your servos dies and pulls down the power box.
