Hey guys,

I'm looking into a new Tx since I just sold my Eclipse 7. It is down to two and i won't say what two in order to not star a flame war. But, I have alot of dual conversion hitec receivers and I always forget, does dual conversion mean it can change shifts or not?

No, shift and dual conversion are two different things.

Since you have a lot of Hitec receivers... I'm assuming you'll want a transmitter which is shift selectable (like your eclipse was) or which "shifts" the same way as your receivers.... unless your receivers themselves are the universal type with the jumper to select which shift they receive.

I think Hitec, by default, is the same shift as "F"

You may to consider Futaba since the shift is the same as Hitec. Makes things easer for you, and there are a lot of Futaba TXs around with a lot of capability. If you know someone that wants to buy an Eclipse, I have one of the damn things I would like to get rid of also. Going back to Prism 7Xs as fast as I can find them.

I need to check though I have one of those Sombra receivers so I know thats shift selectable. Also, I think my two other planes are supreme 8s with the universal selectabilty. Need to make sure.

I have a Hitec Prism 7X and a Futaba 9C. I use almost all Hitec receivers. Work great. All are neg shift.

The only two that I have that are post shift I fly with the Prism which is shfit select.

Since you sold your eclispse I presume you need something wiht more features as the Eclipse is a pretty capable radio.

Here are 4 for you to consider. I have the 9C which has been replaced by the 9C super.

Futaba 9C Super has replaced the 9C that I own, though some places still
have
the 9C. 9C Super has unlimited model memories via removable modules, 7
User-programmable Mixes + 8 defined mixes, 4 snap roll programs, two servo
elevator support, 4 servo wing support, customizable trainer program and
switch assignability. This is a very flexible radio.

Unless you have a large budget, I would not consider this a first radio. If
you have outgrown your entry level or intermediate computer radio and want a
significant jump in capabilities, take a look at the Futaba 9C Super.
This is an advanced sport radio, or a budget competition radio, that has
virtually all of the features that advanced sport power and sailplane
pilots are likely to need. It has a very strong following.

I'm hoping this thread isn't the wrong place to pose another subject related question...


Coattail Subject: Futaba 9CHP Super FSS (with Synth Module) and, the E-Flite Blade CP


My question: Can there be a marriage between the Futaba 9CHP Super FSS (with Synth Module) and, the E-Flite Blade CP stock 4-in-1?


The situation and wonderment:
I'm thinking about purchasing a Futaba 9CHP Super FSS, with the Synth Module and R319DPS receiver. I plan on setting the receiver aside until a shiny new T-Rex SE V2 shows up in my reality. In the meantime, my desire is to use the Synth Module powered 9CHP Super with my E-Flite Blade CP.


I've been doing some research on the web, and have heard a lot of interesting stuff about using the Blade CP with the 9CHP Super FSS (with the Synth Module). Being in the early "still disoriented" stages of the RC Heli experience, I certainly feel qualified to ask what may be some dumb questions. Soon, I may be able to tear-down, build-up and adjust the mechanics on my Blade, blindfolded...well...I may be stretching it considerably...but, the truth is, I haven't focused on the electronics end much, cuz the mechanics and tuning are a pure delight to play with.


Some of the things I've heard:

One guy says I need to buy a Berg crystal for the 4-in-1 unit on the Blade in order to use the Synth Module equipped 9CHP Super with it. Another guy says you can't do it, period. He's tried everything (including talking to the Futaba folks), and he can't get it to work with the Synth Module. He was able to plug in a Frequency Module on his 9C and then it worked.


I didn't want to invest in a Frequency Module if I didn't have to, and from all I've read, the FSS Synth Module equipped 9CHP Super should work with just about any contemporary "receiver". The guy that told me to use a "Berg" crystal, said I needed to plug one of those into my 4-in-1 in order to be able to take full advantage of 9CHP Pitch and Throttle Curve programming for the Blade. Huh? Isn't the "Berg" just an ordinary, everyday single conversion, standard crystal? Just like the one already in the Blade CP? Or am I missing some additional understanding here?


Another gentleman cautiously gave me some advice that sounded like it may apply: Ensure that you can get the right shift. It (the Futaba 9CHP Super...with or without the Synth Module...I'm not sure...) is negative shift, so any rx must be negative shift or have a toggle to go from positive to negative. After that you need to check on dual conversion vs single conversion crystal issues.


Now, here I am, wondering. Is there anyone out there, who understands and/or has had experience marrying the Blade CP with the 9CHP Super FSS (with the Synth Module), without using the R319DPS rcvr? If it can be done, what is really required?

What receiver do you have in the blade?

Is it 72 mhz?

Is it positive or negative shift?
