ok,
Don't laugh at my ignorance and crappy TX for my gasser
Was wondering if I could use my Futaba T6XH in my cppro by just changing the crystal in the stock Rx or would I have to do something more elaborate ? Granted the T6XH (as I have been told (like 4-5 years ago when I was using it to learn how to hover the raptor) is a entry (crap) radio, I would think it's better than the TX that comes w/ the pro if only for the fact it has expo



Also I have a JR g410t gyro that is brand new in the box, could I put this on the pro as well, or would it prolly be too heavy ? I would think if I took the Futaba GY240 off the raptor and tried to install it on the pro, I might run into probs as well.

Thanks in advance

Hi Mosiris,

You can use the Futaba T6XH for your CP-Pro. I use the same TX for my CPs. You just need to make sure you use a Futaba Short crystal (or compatible) (Single Conversion) on the same channel as your TX, in the RX.

Hope that helps.

Do you know if the radio does the CCPM or does the receiver do it?

Atzanik

It is done in the radio.

What's the deal w/ having to use a single conversion crystal ? My futaba rx has a dual conversion crystal in it. Put it in the RX that came w/ the cppro and it wouldn't arm. So, I called the LHS to oder the Futaba Short Single conversion crystal. Hope it works, will help tame the cppro down a great deal ! If it does, gonna be fun programming the TX

Thanks very much Atzanik

The crystal should work fine for you, and I won't worry about the distance. I've never had any range issues with the SC crystal... by the time you are out of range I don't think you'd see that little CP anymore anyway.

As for programming, here are some settings that should get you started:

PPM

REVR Ch1=Normal, Ch2=Reverse, Ch3=Reverse, Ch4=Normal, Ch5=Normal, Ch6=Reverse
D/R Ch1/2/4=100%
EXPO Ch1/2/4=0%
EPA Ch1/2/3/4/6=down 100%
EPA Ch5= up 100%
TRIM Ch1=0, Ch2=0, Ch3=+120, Ch4=0
N-TH 0, 25, 50, 75, 100
N-PI 60, 68, 76, 82, 90
I-TH 100, 75, 50, 75, 100
I-PI 0, 25, 50, 75, 100
HOLD INH
REVO INH
GYRO INH
SWSH Ch A=+81%, Ch E=-82%, Ch P=-38%, 3-S

You might want to play with the throttle/pitch settings a bit to make it suit your style of flying. Using the Futaba on the CP certainly does make the flying experience a lot better - at least it did for me.

Mosiris..are you doing this to eliminate all the electronic glitches in the CP Pro? I have been consideirng switching to an new radio also, but I wasn't sure if it is the stock transmitter, receiver, or control unit that cause the glitchy tail rotor/collective thing.

Can a different receiver be used in conjunction with the stock control unit?

mosiris

Well went to the LHS to go ahead and pay for the crystal. The owner was wondering what I was trying to do. I told him about the info Atzanik gave me. He was looking up the crystals, then pulled a cp pro down from the shelf (we where trying to figure out why the short crystal). Well, to make a long story short, I said, hmm. I didn't try to use the TX crystal from the stock cp-pro TX in my futaba. So I drove back home, put the crystal from the cp-pros TX in my futaba, and it friggen worked !

Yes , that is part of it, but I already had this radio for years for my nitro heli that I has been sitting around due to my fear to crash it due to money. It has a lot more features that the stock radio. One of the ones I like is being able to make the sticks less sensitive near their center positions (exponential). There is also dual rates.
It being a 72 MhZ radio it may be still prone to glitches, not sure, just now setting it up. By doing this I will be elimating one thing in the glitch chain (I hope).

Atzanik ----

Again I thank you ! Once I get it set up it should be much better with the computer radio than the stock (granted when I get to stunt mode I will miss the dial I never used, will just have to make a new model # with a different throttle curve (never got that far with the raptor 30 anyway )

Now the gyro question still lingers. Maybe I need to just strap the thing on and see. I can see it now ... it's alive ! I created a monster !

Atzanik ...

Your TX must be newer than mine or I am just reading wrong.


I don't see this setting in on my TX.

I am thinking that would be STRM on my TX.


This stuff always confues me, but I thought the t6xh only had a 3 point curve.

Again, thanks for all the help !

Hi Mike,

My TX is the [link=http://www.futaba-rc.com/radios/futk58.html]Futaba 6EXH[/link] Maybe the 6XH is a bit different? I'm not sure, I wasn't able to find any info on it. If you don't have EPA settings, don't worry about them. And the TRIM values are just that default trim values.

If you only have a 3 point pitch curve it won't be quite as configurable, but you can still get a nice linear curve from 60 to 90... say 60 75 90 for pitch and 0 50 100 for throttle.

As for the crystal, yes you can change the TX crystal but you can't cross the band. If you are low band (channels 11 to 35) you have to stay in low band, and if you are high band (channels 36 to 60) you have to stay in high band. If you really want to go from high to low or vice versa you can send your TX back to Futaba to have it retuned, but that probably isn't worth it to you on an older TX.

If you were to buy crystals, and you wanted Futaba, you would get either FUTL62** FM Short Rx Crystal 72MHz Low (FUTL6211-35) or FUTL63** FM Short Rx Crystal 72MHz High (FUTL6336-60), depending on what band you are on. If you want to get another brand of crystal, the eSky and Eflite crystals are compatible. Hitec are not.

As to the glitching on the EFlite TXs, it's a pretty common problem that the radio is what is causing your glitches. Going to another radio fixes the problem in all the cases I've read.

As for the Gyro question, I'm sorry, but I'm not familiar with that particular JR Gyro.

OMG I can fly it w/ the computer radio ! It's like a whole new, sexy. silky bird ! This is like night and day even before I tweak it. I bow down to the master jedi !


I forgot how much better it is to have a 'real' heli TX (no, I am not knocking eflite's product. So far I am pleased with what they offer out of the box (minus glitches). It does what is says it will do on the box (minus glitches, again ((too bad they didn't say it can crash )(by real I mean no ratcheting throttle, and , well , you get what you pay for (in my case you can sometimes keep using it) )TX, the sticks are soo sliky smooth and all. Granted I gotta do so programming to get the pitch and throttle curve right. Thank goodness I know not to 'chop stick' cause right now I got full travel on pitch (haven't guaged it yet, but I know I got waay to much neg pitch)


Bah, joy and beer clouding the mind, time to play wow, least I can't break a toon
