I had a similar situation with loss of signal while flying my UMX ULTRIX. Talked to tech support and Horizon sent me a free new receiver. I installed it and had no issues since.
I have and fly 2 of these gliders both with out radio problems. By the way there are two wire antennas, one goes forward the other toward the tail. Found this out when replacing a broken fuselage. Now. off subject, if you guys don’t like Spectrum don’t buy it, easy.
Well, this was my very 1st spektrum product. Unfortunately, it had issues. Also, they oriented both antennas in the same direction when obviously they should have had a 90 degree offset. I was disappointed that the most expensive receiver I've ever had was bad. It's not that I'm against spektrum products, it's that when I have problems with the 1st one I buy I won't be buying any more of them. That goes for non-spektrum products as well. Yep! That's Easy ;-) See you in the Air!
I'm surprised the wings stay on with that much power. Nice. Too bad you can't sneak out there at night and bulldoze or scrape a private runway ;-) As far as contact issues go, be sure to hold the radio with the antenna pointed straight up and the back of the transmitter facing the plane, due to the donut-shaped radiation patterns of typical monopole antennae. Pointing the top of the antenna straight at the plane gives the weakest signal. I myself have a habit of holding the TX down low and almost horizontal, but my DX6i has a pivoting antenna that can be tilted straight up when the TX is held that way. I don't know if that applies here, but something to think about. Happy flying!
Oi! Hobby King Au are gone, spewing, They were the go to for spares and the odd bargain Foamies. Back to cross Your fingers with Brangrood and RC Castle. Aahhahaha!!
PS: I sneak back at Night with My chainsaw an drop Mofo Trees that made the mistake of capturing My exspensive Toys. Mmm?Secret Runway sounds unreal too, hahhaha
Yep! That's exactly how my have my TX antenna set and I always rotate my body so the back of the TX is pointed toward the plane. Very strange and this is the only plane where I've had a comm issue. I never had any RF Signal warnings the whole time I was flying until I lost contact when landing and then received the warning. Hum...that was a bit late ;-) See you in the Air!
@@GroundControlRC That must be a huge concern. There should be 2 antennas in there btw... both mine have. Have you tuned the multi protocol internal module for the spektrum protocol?..... See ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-n2huRPIvMUc.html
See also the 1st (Bruno Porto's) comment in the video I linked for the more accurate way of doing it.. I'm in the process of converting all my fleet to crossfire.... not cheap but I know I'll never have any failsafe issues ever again... lower latency and miles of range thanks to 900mhz and LORA.
My Spektrum experience has been woeful, not a fan and way overpriced down here. Maybe the added carbon rods mixed with the spar could be related to Rx reception? Awesome flying, the vertical rolls into the top out stall flip thingy had Me drooling! Great show GCRC. Have a great weekend.
@@theoztreecrasher2647Yep, I sprayed My Galloping Ghost Chrome an it lost signal straight away, I since have poked out both antenna and it's been brilliant. Thanks Oz!
Thank you much Jono! I am in awe of the Sport Glider ;-) I was so glad it was close to the ground when that happened, although, the Fail-Safe would have kicked in if it had time with altitude. What a shame. See you in the Air!
Hi Oz! I was wrong regarding the single antenna. I could not see the 2nd antenna until this crash tore off the panel under the RX. The 2nd antenna was positioned the same way, along the side of the RX. I have that one pointing 90 deg. offset from the other antenna. It seems very poor antenna placement from the factory. See you in the Air!
Hi there, I enjoy very much your flight. I don`t know but I have not so much 2.4GHz radio experience because I usally used old style 72Mhz band. I guess there is some hugh high vertical antenna near your location. I worry about might be crash possibly and might be some radio interference from the antenna. Another try is better far from the antenna I guess.
Thank You! Yes, that big tower is cellular I believe as it's not putting out anything in the 2.4ghz range. I found the issue to be the DSMX Protocol after having the same issue with a couple of other planes. I switched the Protocol to DSM2 and the problems went away. I'll be buying something other than DSM2/DSMX Receivers on down the road.
I lost signal too man twice i changed locations of both antennas that seemed to help then it happened again but i have read somewhere that dsmx protocol has signal drops but dsm2 is good iam using walkera with deviation firmware i will try again and see if its better
Try a new receiver. I run a FlySky system and had a similar problem until I moved the antenna outside, up under the wing. Problem solved! Would like to run a gyro, but there is on room to stuff on in there.
Hi Dan! I moved the antenna outside the fuselage as well thinking that was most likely the problem but I still had radio issues. It seems the problem is related to the DSMX Protocol. I had the same problem with (2) other planes and moved them to DSM2 rather than DSMX and that solved my problems. I'm going to try that with the EVO and see if that also solves it's problem. If not, it's going to be a Radiolink Byme-A Gyro and WFly RF201S SBUS Receiver. That's seems to be a great combination.
Good video, I have a Conscendo Evolution and absolutely love this sport glider. My antenna wire is coming out of the bottom louvre, that is were the manufacture installed it and I have no issues. But, let me ask you a question, did you do an 8 point range test (moving the aircraft 45 degrees 8x at the required distance, then retesting at each 45 degree position) test prior to first flight? It is amazing how many time I found a receiver position fail at one of those 45 degree point or you will see were the weakest receiver position is to the transmitter. Good luck…. JT
Hi John! It's and awesome glider! I did perform a standard range test but not an 8x position test. I have approx. 12-15 flights on this glider and performing aerobatics it has been in every profile to TX possible. I've never had an issue until the last couple of flights and it's never been crashed. Just to be on the safe side I'm going to replace the stock RX with a RadioLink Byme-A Gyro and SBUS RX. I've used that setup in several planes without issue. I'd sure hate to lose it because of an unreliable RX. See you in the Air!
@@GoofballFlyer I grew up just 60 miles south ;-) Small world. No, I didn't, but I might give it a go and see if they will replace it. All they can say is no ;-) See you in the Air!
This is weird. I have never had a lost signal with my Conscendo (or several other E-Flite models) in literally hundreds of flights. Lately I have GPS telemetry that gives me distance from the launch point. I have had it out to 800-900 feet and no issues. I am running the OEM AR637TA with no antenna mods, GPS and altimeter/variometer modules. Transmitter antenna issue? Just lately I have replaced all my non-AR637 receivers with the AR637T. Love that receiver! But you do have to know how to position and program it.
Well, we all get bad ones from time to time. It's sad that my 1st and only Spektrum Receiver was a dud. It's by far the most expensive Receiver I've ever owned. No Transmitter issues as I fly all of my planes with the same TX and have put several flights on my new Volantex PhoenixS with no issues. I even tractor around the same way in the same location at the same altitude and distance for landing. The RX antennas were at the factory position when I received the 1st signal warning. Bringing the antennas outside the fuselage with 90 degree offset didn't help. Not a single issued on my $16.99 RadioMaster SBUS Receiver on the PhoenixS ;-) I also had my Arrows Viper EDF Jet out this morning with the same TX, no issue. It has a $16.99 LemonRX Receiver in it ;-) Most of my Receiver are DSM2/DSMX, so I know it's not a protocol issue either. I'm going to replace the stock RX with a RadioLink Byme-A Gyro and another RadioMaster SBUS RX just like I have in the PhoenixS. So Hoosier, where are you located as I grew up in Indiana ;-) Awesome State and I miss it.
This is still my fav bird G.C... It has such a great blend of speed, power, aerobatic ability and gracefulness IMO. I love how they fly.. Do you have a pecking order for your fleet? I'll need to check back your videos to see if you ever did one for that subject... seems to ring a bell... if not I'd love to hear what your pecking order is
Hi Paul! This is definitely my favorite Sport Glider of the (3) I've flown as it's so aerobatic and has such great power. Flies like it's on rails and so darn stable and graceful. I don't know if I have a favorite plane as I like to fly all types of planes. This one if one of my exceptional flying aircraft that I would not part with ;-) I'm going to replace that RX though before I take it back out as I don't want it destroyed. I'm going to install a RadioLink Byme-A Gyro and an SBUS RX. The same setup I've tested on other planes that works extremely well.
You're correct! I could not even see the 2nd antenna until this minor crash ripped off the cover on the bottom of the fuselage. What I don't understand is why they had both antennas running parallel to each other right along side the receiver. Surely they knew this would block signal. Even after routing the antennas outside the fuselage with a 90 degree offset from each other I was still getting RSSI warnings. Time to replace the gyro and receiver. See you in the Air!
@@GroundControlRC Sounds like there’s something wrong with the receiver I have a lot of flights on my evolution and I’ve had it so high that I could barely see it and never had a warning I can check my transmitter Telemetry and see if I’ve even had drops. As far as the antenna placement that comes down to a good worker named Dave on Monday and shit hole Joe on Friday with two hours left of work. Lol
@@sxsmarine4075 Hehehe...I think you're right about that worker ;-) I had approx. 20 flights on this glider without a single problem until this flight. I just happened to get a receiver made by Joe ;-) See you in the Air!
@@GroundControlRC In the off chance you haven't visited - there's some excellent swooosh content here. ru-vid.com He has an ideal flying environment as well!!
I'd be calling and complaining to the distributer and at least asking for a new receiver. Horizon Hobby I presume. They have always been more than helpful with me.
Hi Jack! I'm not sure I would trust one of the Spektrum Receivers again. I may put a Byme-A Gyro and one of my SBUS Receivers in it since I've never had a problem with those. See you in the Air!
I usually remove the spektrum rx from my planes because the range is very limited. You have about 700 yards of range which is a great distance but not that far if you like to fly high as well 😉
I hate Spektrum... Wouldn't use any Spektrum radio since it lost signal and Crashed my brand new E-Flight Apprentice plane that came with that Spektrum radio a few years back. I'd tear out that Receiver and put in any better quality Receiver.
@@Mikeylikesit1968 Nah... IDTS... Looked like it snapped right while turning left to get to the runway.... The giveaway that it's the crap Spektrum RX is the "RF Signal Critical" warning at that close distance.....
@@Mikeylikesit1968 Sorry... no.... I won't touch a crappy Spektrum anything anymore... Haven't had a Radio problem since.. Glad you are comfortable flying while the radio knows (and is trying to warn you) that a signal strength RSSI signal is low. Hey it's not my $$. Just saying...😉
