Re: Can I really trust this 2.4 stuff?

I think I'm in the 15% minority of the users who actually have radio problems. I know I'm getting rid of the 9303 and probably picking up an Airtronics... people seem to have great experiences with them and Futaba at my field. Funny because I've been a JR snob for years.... but after losing 2 planes to the 2.4 9303 and crashing another twice, I'm going with something different. My 72mhz 9303 hasn't given me any issues except when I used crappy GWS receivers in cheap electrics, and several crashes with 3 different Berg receivers that were supposedly the "best" Maybe I'm just unlucky. |

Re: Can I really trust this 2.4 stuff?
Did you reuse electronics after those crashes? Did you try and send your radio in?

However, I tried a BRAND NEW JR921 receiver in another plane and lost all control after a high speed pass and it completely destroyed it. I also lost contact multiple times with an EDF jet which almost resulted in more crashes. I haven't gotten around to sending it in yet, but I'm not using it for anything except cheap foamies now. As for the Bergs, I tried 3 different receivers in 2 different planes with every antenna routing imaginable and still managed to crash them all after complete loss of control (all electric planes). Interestingly, I've had no issues in glow planes with them. As it is, I'm frustrated and am no longer buying JR products when possible. After spending that much on the radio and expensive receivers, I'm just not willing to take a chance again. My DX6i was more reliable than this, and even it caused me to crash my T-Rex 450. I might just go back to 72 for a while before switching to the Airtronics. 16 years of 72 and the only time I had issues was with POS receivers... |

Re: Can I really trust this 2.4 stuff?
Do you guys ever range check your 2.4 to make sure it is bound properly?

Re: Can I really trust this 2.4 stuff?
If you range check and come back to find one of the satellites is blinking what does that mean?

have you thought of maybe there is something with the electric motors or speed controllers causing a interference issue. it doesnt make sense that only the electric setups have issues. i know of alot of people using jr and all electric and no issues. so maybe there is an investigation needed. just a thought. |

Re: Can I really trust this 2.4 stuff?
If I found only 1 Rx blinking I'd be a little worried. At best you turned off your plane but not the radio and then turned the plane back on. The Rx thought it was a brownout and only 1 of your RX's is the new quick connect.

MadMonkey, I certainly don't mean to belittle you, I'm just trying to help. Did you range test the R921? How many satellites? How was your transmitter antenna oriented? Do you have a native 2.4 system, or module based? Did you use a data logger? I hate to hear of your misfortunes, but you could have something wrong that has caused you lose airplanes. I think if you were a little more proactive with sending the transmitter in if you thought there could be an issue with it, it may have saved you some greif. From my experience, 2.4 is more tolerant of poor setups than 72 was. It's not perfect, and I doubt you'll solve anything by switching radio brands. To me, that signals that you think there is something inherently wrong with DSSS, versus FHSSS. Before you go and spend more money, I would send the radio in, that way if you want to sell it, you at least have a good bill of health to go with it. |

Re: Can I really trust this 2.4 stuff?
I didn't have a data logger and this was the day of the crash on my Extra but after rebinding and doing extensive range tests and removing a old satelite I had on the AR9000 it worked perfectly for 4 flights and then a lockup. The batteries on board where not a fault and I rechecked the system in the end I believe it was the tx pack that went bad and dropped voltage. I brought this up in another thread but anyways I've had my good and bad luck with 2.4 the only problem I'm seeing is a lot less problems with Futaba Faast then Jr/Spektrum. So far with a friends experience on it after 3 years of no problems I would switch over to a 10Fg if I had the funds to replace all my receivers and radio. btw I sent the radio and receivers back to HH for check up.
