Yes, you do run low gains in the Vbar. If you look at the pic in my first post I did put a screen shot of the gains as they are now. I dont believe its a gain issue as the heli was very soft, and I have gone from a rigid head to a softer head so if anything the gains needed increasing ever so slighlty But I will leave where they are for now.

I just see your message Angelos.

Get your pitch forks out and blame Spektrum! Switching to Futaba may just be an expensive way of masking a problem.

I dont think its a gain or mechanical issue either, if you were going FFFF and lose all your signals at then its going to upset the apple cart.

Missed signal:

"This Error is raised, if for 50ms no new signal arrives from the reciver. Depending on the hardware connection this can point
to a problem with the connection to the reciver/satellite. In case of sattelite recivers used, all channels will be accused at the same time. In case of single channels, this can happen seperately on each channel. Closely check your wiring for broken wires or connection problems"

Antenna swaps followed by missed signals on all channels would suggest you briefly lost contact with the model, How are the satellites mounted? That swanky SFR fuse might attenuate the RF a bit.

I'm running the white bushes and two black rings, so Rigid, all my gains are the same for FFFF as they are for 3d and low RPM <700 to 2260 the only thing i've done is added more expo and lower Duel rates to the Elevator channel for speed flight and use smaller tail blades.
I've never had a miss on channels or antenna switching, I don't know if the latter can happen on Futaba?

We started to have a more throughout look at these very high runs and found this post that reports similar issues at over 140mph. Search on the page for "Learning #2" and read just below. Unveiling - SFR 2012 - Page 1 - RunRyder RC Helicopter

Well said.

Welcome to rcheliaddicts.

was nothing to do about pitch forks I was concerned with range issue if ben flys so far away its a dot on the back of its blinding speed then it would worthwhile considering the modulation used from either JR Futaba and I think hitec also. The last thing anyone wants is to see all Bens hard work and time invested in pieces because of a range failing.

[Jamin_00]

It does appear where ever Speed runs take place and speaking with many guys who fly speed such as Oliver Jellen etc they do all use Futaba and Im getting the same info off HF. Im not against Spektrum, been with them all my heli life just prefer the JR radios but if these guys are all saying it then I'd be an idiot not to listen and take it seriously.

Fredrik posted this on my thread

I have a theory, conspiracy theory, after some info slipped on the net a while back, I'm pretty certain it's linked somehow, however, that theory is not something I will write, but it made me change brand.


If you want to keep the radio, I would rather suggest a fullsize RX, even a HobbyKing version of OrangeRX might be an idea, it's craftmanship is good, I have inspected it myself, and they have a version with SBUS out on spektrum...

Got a major change happening soon so could do without this tbh but if it has to be then so be it

Do you have any photos of how the satellites are mounted? Did you already say the cables and connectors were okay?

Regards,
Rick

[Jamin_00]

Hi Rick.

I not got a pic but they are mounted at the rear where the skids connects on either side and are mounted at the angles as recommended.

I have not looked at it anymore yet so still to check the connectors and cables. I guess the next chance I get will be next weekend as its the mrs birthday Saturday so it wont fly this weekend and I'll be out with my other heli's on Sunday.
What system you guys run?? See any issues??

[JoeBailey]

The Slope guys also run futaba/multiplex. They say on long runs out from the slope they can outrange spektrum gear with ease and when you look at some of those 5m span gliders they can really test the radio range.

[R.J.]

I personally run Spektrum in all my helis, but in the SFR, Scott runs Futaba sBus Rx with BeastX FBL controller, which replaced Vbar 5.2 that was pitch-up sensitive at very high speeds.

I have had a satellite cable wire break from the connector, but only after many, many flights on a nitro heli. I would check over the cables and connectors, and make sure there is line of sight to at least one satellite at all angles (esp. the left antenna as stated in MrMel's link on HF).

Regards,
Rick

Ben,

Did you see this post about antenna switching? The Vbar was not setup correctly for the type of satellite. Wonder if that could be the problem? Sounds like you have to have the frame rate and DSM2/DSMX set correctly. I think the JR11X is 22ms frame rate.
antenna switching again - HeliFreak

[Jamin_00]

Just caught this Rick.

Will take a look and see what it says. I take it the DSX11 and the 11X are the same radio just for the 2 different markets??

[Jamin_00]

Latest update.

Most know I did switch to Futaba with a 14SG and whether its due to different postion of the ariels or what I dont know but not one error in the logs or issues but in fairness I do now have the 2 ariels poking out of the airflow holes at the back so that could be a factor as when it was on sats I was forced to have these inside the fuse. I have noticed a little trend lately too in switching over including some big names haiving issues, none other than Marco Rebello kept having glitches so I know its not just me Most big names fly close 3D so dont get the chance to have issues but start flying 500m away and 600m high they do start to appear it seems. But then I could just be trying to justify the expense of it

On to flight reports. It hadnt flown much due to the weather and testing 1 or 2 items on TDR no2 before they went on here but it has had a good few flights lately. Mainly running in the new 7s 5000 Optipower Ultra cells that Im testing for Opti. Got Spin Blades making some custom one of blades. Marc was speaking to Andy at a show in Germany and wanted to try some special designs out and so on the way back from Rotorlive Andy and the guys popped in for a coffee and dropped of the first set of custom Matt Blacks for me to play with. What they are doing is weighting the blades more and also changing where the weights are so therefore giving the blades the perfect CoG for FBL speed flight. Man does that Marc know his stuff.
Then I been playing with the Vortex. The idea being that its perfectly tweekable and very easy to use what Vbar call bank switching. Therefore I can run the same headspeed and have 3 different flight styles so when testing I can in one flight effectively test 3 different set ups. Makes it much easier and quicker to get results.
The Pyro special Competition motor will be here soon too

The past few weeks have made me realise my flying is so the limiting factor here. Its not just a case of point and shoot as it were but the slightest move, wrong approach angle etc etc can cause so much speed to be lost its crazy. I just need time where I can fly and until it warms up I aint gonna get that.

Bring on the spring or summer anything this this freezing cold

Ben , you have a small write up about your speed run attempts in this months (April) R.C.M.&E. mate with a photo .
