Corsair and T-28 Trojan

by Fred-Busmann
(OHIO)

I have probably 10-20 flights on the F-4U and as many on the T-28, and both have the 72 mhz transmitters. I had nothing but trouble with the DX5-E radio in the Corsair-(glitches and nervous servos). Seems as if everyone loves the worry free 2.4 Spectrum set up, but I am starting to hear nasty little rumors about the dependability and "un-binding" while in flight with the DXE5-6-and 7 series Spectrum receivers. Has anyone else had problems that you have come across, Pete?

Hi Fred,
I have a DX6i and so far haven't had any such issues. But I do have 'nervous servos', as you put it, in the Blade 400 heli which uses the DX6i with an AR6100e Rx. Similarly the micro servos in my PZ Sukhoi are constantly twitching, but my friend contacted Horizon Hobby about this and they said it was normal for that technology. The issue certainly doesn't show itself as any adverse effects in flight.
The un-binding does sound a bit worrying though. The only major issue I had was with a couple of the cells in the Tx coming loose because the battery tabs had somehow pushed flat; the connection kept breaking while I was trying to set up the heli and so the Tx kept rebooting and wiping all the settings from the memory. Not good.
I suppose we have to remember that it's very new technology, and maybe they haven't got it as perfect as they think they have yet...

Bind OK
by: Michal

Hi, I have DX6i and different Spektrum receivers (AR6200, AR6000, these 5-in-1 units as found e.g. on mCX), but the technology seems flawless to me in the matters you're describing.
Sometimes it just can take some time to bind or connect (typically with the AR6000, but that I suppose might be because this Rx is just DSM, while my Tx is DSM2), but once it locks it holds
If you're describing un-binding, I'd suspect that perhaps you might have wrong piece. This technology absolutely should not unbind. I've lost control of a plane only once, but it was because of the bad connectors - it short-circuited, apparently dropping the voltage too low - which will make the Rx to reboot (a process that takes few seconds). The lesson learnt is easy - do not use cheap connectors (these were Tamiya) and get something that can handle that current.
Overall, in my experience if you're experiencing the system getting unbind, you should return the hardware and request a new one. This is not standard behaviour of the product.
