New 2.4GHZ RECEIVER NO NEED FOR POWER BOXES

[cjcyclesrc]

I just got a call from my LHS. Mine should arrive tomorrow.

And do you still want to spend an additional $100 on matchboxes? If I wasn't getting away from Hitec servos or didn't need matchboxes, I could make this work, but something like a Smart-fly Power expander EQ10 still sounds like a better option if you want full power to all servos AS WELL AS the receiver, and servo matching all-in-one. I had one on backorder 3 months ago. I saw it in use in one of McConnville's planes and it worked fine on a 43%er, but I still prefer to not run matchboxes and want the piece of mind of having full power to all my servos, so I cancelled my backorder...I bet a year from now they'll wise up and come up with an even better solution (power distribution, power back-up[like the D-cup], servo matching, and receiver all in one).

The Spektrum stuff has servo synch-not supposed to need matchboxes

[MattyMatt]

Servo synch is not matching the servos... it matches the channels so there is no latency issue.

What happens if you use a Smart-Fly Power Expander. I know there's no need for a power box type setup, but if you use, let's say, an EQ-10 because of the need for independant servo programming the Power Expander gives, what happens to the receiver voltage? The specs show the receiver works between 6V and 10V.

The EQ-10 etc. supplies a consistant, filtered 5V to the receiver. Does this mean that this receiver won't work with this type of setup?

I find it funny that a lot of you guys that are dead set against using a Power Expander, are all excited about these new rx's, which are basically set up to work like Power Expanders (a poorly designed one). 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).

If you want to use a Power Expander, I think you are better off using the "old" type of rx with the Power Expandrer.

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.

[BubbaGump]

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.

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.
