5014 in electric heli

[Dokey0]

Hi,

Has anyone tried the 5014 RX in an electric heli ?

Just going to install one in a Xerg 600ep electric heli, and wounder if anyone has run into problems with radio interference with this setup (elec heli and 5014 RX)

Thanks,
Ryan

I've been running one in my Ion-X for about 10 flights or so.(the weather has sucked here for the past 3 or more weeks) No issues, other than needing some expo for the first time because it is SOOO quick!! :shock: Never used Expo on the 9Z.

I know Russ McCutcheon has been using the 14mz and 5014s with his Ions. I have not heard about any problems from him.

[Russ McC]

Nope, no problems!

[Dokey0]

Thanks guys, makes me less nervous when I give it a whirl :glasses2:

Edit: Never looks like there is much going on in this section, but its still good that some guys are always watching to try help out.

Thanks,
Ryan.

I am getting lock outs :arggg:

Pinion is off the motor and I am just running the motor free, but it is constantly loosing radio connection :(

Changed over to a dual conversion ppm RX and all is ok, just do not particualy want to use this RX when flying though.

[WillJames]

So motor and fan are turning but nothing besides the clutch stack is turning? Maingear is stopped and all the rest of the moving parts are stopped?

[Dokey0]

Hi baja170,

Everything is in the heli, except for the pinion which I have taken off the box, so it does not drive the main gear etc while I setup the heli

As soon as I raise the collective/throttle stick, the swash starts to rise and then I get a lock out as the motor picks up speed.

I have some pics in my gallery on RR, will have to get some put on here sometime.
Hope you don't mind me posting a link to my gallery here: http://www.runryder.com/helicopter/gallery/4445/

No big deal at all on the link. Sometimes they are blocked, sometimes not.

I forgot you are talking E-Heli. I had a box myself, but definitely not this issue.. Did you get it new? How are the bearings in the box, do they feel smooth. If I remember correctly the shaft that goes up from the box goes into the lower clutch stack bearing with the pinion on it. Is there anything to support that shaft when you run it without the pinion on it? How does your lower clutch bearing feel, is it new or wqs it a glow Raptor first? Where is your antennae routed? Is it anywhere near the lead coming from your ESC? Are you running the 77-O Heli ESC?

[Dokey0]

This is with the Jazz control 55-10-32, the heli is brand new.

Antenna is routed opposite side to every thing, well out of the way.

Has been mentioned that the RX battery lead and speed controller lead should be kept separate, so I will try that next.

Also tried a Futaba PCM RX and it shows no sign of misbehaving on the table, I wounder if it is the 5014 being to sensitive, or the PCM RX will show the problem in the air ?
:dontknow
Just not comfortable with how it is, keeping safety in mind !

[WillJames]

I wonder if you have a bad RX if another PCM RX works. The 5014 should not be that sensitive. I know Shannon is running all 5014's in his fleet and a bunch of them have bee crashed HARD and no problems so far...

You know anyone with another 5014 to try in your heli. Since everything is brand new and another PCM RX works fine, makes me suspect the RX.

Check this out, havent had trouble my self but some have. Futaba has also said that this RX is more sensitive then any other of there RXs.

[WillJames]

It will be interesting to hear if cutting off the antenna works. Interesting "fix", but if it works then great.

Also, this should not matter, but have you tried changing channels and see if it makes any difference with the 5014?

[Dokey0]

Well I have changed the wires around a little and that did not change anything with the 5014 RX, put the PCM RX back in and it behaved immaculate.

Took the heli outside with no main or tail blades on, and got the heli up to RPM, at the same time slowly moving all the cyclic etc servos and seemed to respond super smooth, so hopefully no lockouts(fingers crossed!)

Will let you know how I get on.
Also will try another 5014 RX later.

[Dokey0]

It flies :glasses2:

No glitches, lockouts nothing.

Maybe just the 5014 RX is just too sensitive

[Phaedrus]

If you have not done it yet, absolutely trim the 5014 antenna to 21.6 inches from the case. This is the recommended length now and all new RXs are shipping with this length.

[RCfan]

... all new RXs are shipping with this length.

Where'd you get this from and who's selling these "new" Rx's?

[WillJames]

I just got a new one but did not measure the antenna before installing. :DOH

[Dokey0]

Is this just for the US on 72 mhz, or does it apply to everyone ?

Thanks

[DavidH]

Dokey,
The antenna length was originally issued to the Team Futaba members here in the USA to check out. So I would think it may just be for 72mhz here in the USA. You would need to ask the service center in your country if they know anything about it.

I've run a g3 in my t-rex with the wrong length anttena no problems. A little heavy for it though C.G. all wrong. I really did it to make shure the receiver was okay. It was until I put it in my raptor 50. It should work fine for you though. good luck. Tim Korn

From the 14MZ site:

Current-production receivers have the 55 cm. antennas.

I cannot tell you what the stock status is at Tower, etc. Regardless, if you get one with the long antenna, cut it down. No big deal. Futaba authorizes it and it does not effect your warranty. In addition, since the new production comes with the short antenna, I would cut any one you have now to the 55cm (21.6 inch) length.

It is absolutely for the 72 band only.

Cut your antenna to 21.6 inches and I'll bet it's rock solid.

[Dokey0]

I would but that is only recommended for the US on 72mhz, not for us who are using 35mhz.
I have three other 5014 RX's in IC helis and have never had a problem, its only since I have tried one in an electric heli :(
Could still be worth a try I suppose, thanks for the suggestion Phaedrus.
