That's a good theory to assure a successful system, but it doesn't answer the question - will they work with a Power Expander only supplying 5V to the receiver?

I can't answer that question because I don't know.
Why would you want to use these rx's (instead of the "old" style rx's) with a Power Expander?

You know, someone, inevitably will try it. I was just wondering the outcome.

I saw this in a airplane before it was out, I think this is the way to go. The plane I saw it in I think he had Matchboxes in the wings. It was a bipe.

You are basically agreeing that Power Expanders do improve performance, otherwise you wouldn't be interested in these new rx's. The problem is, these new rx's have solved the problem of current flow into the rx, but still have a problem with current flow out of the rx due to only having one standard connector output on each channel. If you want to use 3 or 4 servos on a surface, and need to plug 3 or 4 servos into one standard plug output, you are severely limiting your current flow. It's kind of like pouring water through a 2" PVC pipe, but you have a reductuion down to 1/2" diameter in the pipe toward the end of it. The water will start pouring into the pipe fine, but will slow down severely when it gets to the 1/2" reduction area (this is like using the new rx's with one standard output plug per channel). The water would flow much faster if the pipe were 2" the whole way (this is like using a Power Expander and not having any limitations on current flow). Jim

What I dont understand about your Pro expander type posts is what makes the tiny pins on a Powerbox/expander setup any better than the ones on the reciever???
The trace on the Reciever buss is every bit as capable as on the Power expander.

Both systems are limited by the servo connectors which you have to have at the moment somewhere in your system.


The manual clearly stated 6-10v on the 9100 using one or both of the ec3 connectors.
Using a PowerEx you will have to figure out a connection from the source to supply both the Power Ex and the reciever thru a Deans.
Will get round to trying this weekend.

Note I have the 9100 and a powerex so not biased , I just dont see a clear advantage to using the power expander when using a channel per servo.

Alright smart as*es. How do you freaking think they matched up servos before the matchbox?????? Do you remember all TOC airplanes falling out of the sky because of not using matchboxes or all of the airplanes at the older Joe Nalls falling out of the sky because there wasnt a powerbox or matchbox in the planes with multiple servos on wings, ailerons and elevators???? What??? You dont remember???? THATS BECAUSE IT DIDNT HAPPEN!!!!!!!!! HELLLOOOOOOO Anytime any of you would like to check my plane out you are more than welcome to have a look at and hook whatever amp draws or whatever so you can say my system will fall out soon can do whatever the heck you want. I'll just stand back and laugh. The planes I have, have been flying like this for numerous of years!! My 40% Carden has been like this for over a year and god knows how long my other planes have been like this. I'll be at Joe Nall and you can check out my planes all you want. Heck I'll be there starting the Saturday of Joe Nall and you can check my volts for me after every flight for me to be sure I'm not losing any extra power from not having a matchbox. And I'll guarantee at least 8 flights on it with 12 minute flight times. Oh and I'm not the only one out there flying without matchboxes. I can hear it now you'll probably say its not smart to run dual recievers either. I'm waiting for that one to arise as we speak.

The difference is that the 9100 only has one output per channel, while the Power Expander has 3 or 4 outputs per channel (depending on which Power Expander you use). When using multiple servos per channel with a Power Expander, each servo gets it own current source instead of sharing with other servos through one standard connector.

You just plug your batteries directly into a Power Expander via deans plugs, and the Power Expander supplies current to the rx, and to the servos. It couldn't be any simpler.
You don't need to use a deans plug to supply power from the Power Expander to the rx when using a Power Expander because the rx only needs a small amount of current. The servo current is no longer running through the rx.

I don't think anyone is saying that you can't do it the way you are doing it. All we are saying is that due to new technology, there is a better (easier) way to do it now.
Each person can match the servos any way they want to.

I agree with that statement. But the way everyone is coming at me they are saying its impossible and I'm a complete idiot. They are the complete idiots for making statements like that. Agreed it can be easier with the new technology but thats all it is, easier. Its not a need to keep an airplane up in the air. The plane is not going to crash if you dont have a powerbox or matchboxes.

I agree, the airplane is not going to crash just because you don't use a powerbox or matchbox.

I don't use matchboxes, because they don't provide me with proper current flow unless I use yet another battery plugged directly into the matchbox. That's more weight.
I do use Power Expanders, but I don't use them for the servo matching capabilities. I use Power Expanders simply because of their ability to provide me with better current flow.
I use programmable, Hitec digital servos and program my servos to match.

I used to match my servos the same way you are doing it. This was before the new technology, before I had a choice.

Consider another issue if you will. Our servos are drawing more and more power. I'm not sure how you set your planes up but if you don't have as many channels available as servos, you are likely using a Y. As servos get more powerful, you may start to see problems with being able to get enough current through the one connector on the single input side of the Y. I'm told the limit for a servo connector is about 3 amps. 2 8711's can draw more than this. As we are expanding the number of channels to 12 or more, this becomes a non-issue as you can run each servo through it's own channel and avoid matchboxes, Y's, and powerboxes.

I'm not saying this has been or will be an issue for you, but just something to consider as the technology advances. Guys flew 40%ers with nylon gear 100 oz servos a few years back but it doesn't mean it was the best solution.

I fly with dual recievers, 1 battery to each reciever, 2 switches, 2 regs, 2 8611's per surface except rudder which has 3 servos and on the SWB self adjusting servo tray. Works perfect.

[MattyMatt]

You're all right.
I believe the issue with the servo matching isn't so much the servos but how they are installed... we are having to adjust the movement for improper geometry.

I got the call last night from my LHS, that my 9100 is in! I will be running 8711's, A123's and try to not use matchboxes. I want to keep this one really simple.

I will be making up a very short "Y" for the ailerons and the rudder. Yes we all know that the stock servo connectors can only handle 3 amps continuously, besides the rudder you almost never will see the peak current draw on any other surface.

I am running a EQ10 in my 42% 260 and think it works really well. I also have ganged servos on every surface (12 8611a). On my new plane, Dalton ML300 42%, it will only (2 servos) be ganged on the rudder and ailerons (8 8711)

In my opinion this is THE setup for a 50-100 cc sized plane with only one servo per surface hands down.

[SmoothFlying]

It seems like everyone now is starting to make sense!! Where is "Exeter Acres", "Pale Rider", "Bodywerks" and "Windecker"???? I believe they need to read the last posts to get some insight and knowledge. I believe lightning will be striking there planes instead of mine!

[ifly3d]

Matt and Chris,

You are both correct. I have never run a power box and not had any issues. But I do run match boxes. I try to get ecerthing as close to perfect as I can get it and just fine tune with the match box, most of the time its only one click on the match box. I all so run two leads from my reciever to the match box from a spare channel, this is power only so I have two power sources to the match box. (This is on the 300 with the new 9100 ) on my other planes I run power from the regulator (fromeco with three outputs) I all ways leave the jumper in place on the match box. I could get away from the match box, but I like the fact if I have a servo go out on me at a contest I can change one out really fast with the match box, then fix it later.
