My MQX quad I also had to reverse 2 channels on the 9XR whereas same model on my DX6i it worked as BNF without any reversing. At least with a plank you can get the controls going the right way in ground setup. The quad needed gentle low hover checking.

Same solution used for 9X can be applied to 9XR.
Replace one of the pots with a rotary switch and 7 resistors, value around 700 ohms each.

I was expecting similar results to the DX6i + R610. I've always been a fan of this combo and been able to fly at the edge of visibility with this combo and never had the issues I've had with 9xr. Unforutnately that's not the case though with 9xr + DSM2 Module + R610.

Since I've had the 9XR I've had 4 reliable airframes drop link, one 3x in under 2min, none of which had any issues in he year leading up to the DX6i to 9xr switch. I've been trying to troubleshoot what happened, I suspect the gimbals were loose for most, but now I am wondering if I was on the edge of range.

Since all of my planes are setup with this combo, it makes me very nervous to fly most of my planes, because I know I fly atleast 80% of that range regularly... Just makes me uncomfortable, knowing I am walking he edge of the range.

I will have to wait for some results from the new full range rx's, but right now I am considering keeping most on DX6i, Frsky is looking better and better, and 9XR keeps looking less and less like a diamond in the rough that I thought it would be.

I know it sounds like a lot of whining, but if I can save some people having to bring home planes in a box of parts like I've been lately, hey. I know that alot of people are making the DX6i to 9xr jump, expecting the same performance like me, but they should be aware of their diminished range and whatever you do, glue the gimbals before flying.... Trust me!

Maybe the issue is with your RF module and not the TX? Im using the OrangeRx but fly all at short range so far, small slopes or quad in backyard. Really want Turnigy DSM2 RF module though!

Agree, I can't see how the module's range would be affected by which transmitter it's fitted to, unless possible the antenna ends up in a silly place. If the Orange module is below par, not totally surprising at the price, then a genuine Spektrum module would be the way to go.

I think what you experiencing is the shortfall of spektrum frequency hopping or the lack of it. I've flown in the same place using same equipment (DX8 and AR6200 dsm2) and have had no issue on most days but on two different occasion I kept on loosing connection to my plane. Lucky it was high enough for it to reconnect and I was able to land safely. I later got DSMX rx and never had any issues what so ever. I now use 9XR and FrSky combination which is a bit easier on my pocket as my fleet gets bigger.

Aeajr,



I expect you know this already. For anyone who hasn't heard of it yet, by 4 axis I mean flying an aerobatic glider with the throttle converted to spring-centred and driving the flaperons up and down. This is normally used for ultrabatics , which is a new name for low, slow, in-your-face aerobatics with gliders like Le Fish or the Flow.

I had my question answered in the slope forum. RC Tanks Australia is selling the extra arm and hardware to mount it, to convert the throttle to spring-centred. All you need extra is a spring out of any transmitter. This info courtesy of Surfimp.

Hi e guys
I just got my 9xr and I really happy about it !

can someone help me because it seams that I have only 6 chanel working .

thank

You'll have to go into the mixer and program those channels to do something. The stock templates have 6 channels pre-programmed at most.

this brings up something a was wondering. would it be cool to spring center a radio for cp heli.new to cp never even hit throttle up yet but seems spring center throttle would be neet. even a switch that could switch between no spring and spring

thank you ! this is my first turningy radio !

No, that's not how you fly a CP helicopter. The throttle/pitch control must have smooth friction, not ratchet action, and certainly not spring centering. Unlike the cyclical controls, there is no "neutral" in pitch. The starting point is zero pitch before takeoff and pitch in the air is typically 3 or 4 degrees.

Learn to fly a helicopter and you'll soon see why you don't want spring centering.

Note that this is totally different from the glider example, where the point is that the "throttle" stick is being used for flap action that the pilot can use in unison with elevator to get very small turning radius (as in control line stunt models). It needs to be spring centered because its no longer a throttle control.

I think he means 3D heli flying, where there is both positive and negative pitch.

I have a 9XR with the Orange OpenLRS module on its way.. and have been pondering the antenna mount on the module on the back of the 9XR... which is far from perfect





The SMA socket on the TX module appears to be fitted with a Pigtail.. so I am trying to figure out if I could fit a longer pigtail an mount the socket on the 9XR next to the trainer ports... and fit Diamond UHF antenna on top ..






This would give the longer UHF antenna a better mounting point..

Has anyone done anything similar.. and if so any pics / advice they could share ?

Spring loaded still doesn't make sense, since the heli won't fly at zero pitch.
