My Dad's heavily modified stryker is having severe glitch problems. He's using a Hitec 555 reciever, and we tried with another 555, and the glitching was only marginally resolved. Replaced the crystal, no better. I tried my electron 6 (couldn't be any better than 555, just smaller and +1 channel) with my radio on my channel. No problems whatsoever. Flawless range. What could be wrong with the setup? Antenna replacement time? Service time? I'm going to see if the electron and 555 crystal are the same, we'll try his channel with the electron. That would point to the transmitter.

You guys are a great help! [8D] I've been having lots of problems and questions lately!

I gave my dad my electron 6 after trying it with a range check on his channel... 555 and electron crystals are interchangeable. The electron performed flawlessly... So, it's not a radio problem, but if you have anything to add (unlikely, not Futaba's problem at all now), go ahead! I'm glad it's a safe plane now!

We moved this to the Hitec forum because this isn't a Futaba question.

Well Hitec? I'm waiting... [sm=tired.gif]

Yeap the dual conversion crystals are interchangeable with all Hitec dual conversion RX's.

Everything is the same of the RX installation less the RX itself?

Did the 555 ever work in this model?

How are the range checks being performed static without engine running or both?

More than one TX has been used for testing? What kind of module?

The 555 did work in the model, but it glitched heavily. Even during range check. I moved the 555 around quite a bit, with no change in range. I even hooked up a second 555 outside of the model, with only marginal positive results. Once I switched to the electron 6, the improvement was staggering. The range checks were performed with the motor off, and at half throttle (electric brushless). The transmitters used were T6XAS (ch 43) and T9CAP (ch 60), with stock crystals and stock modules. Oh, one thing I noticed was that the 555 antenna was a smaller wire than the electron 6, and it looked shorter for some reason... [sm=confused.gif] Is the 555 a lesser reciever than the electron 6? Some kind of change in circuitry made it better? BTW, would you recommend an OPTO isolator in between the ESC and the reciever? (Just hit me).

Guys? [sm=confused.gif] Can you tell me anything about the differences between the electron 6 and the Micro 555? Either something is wrong with both 555's I have or they're just not as good of a reciever as the electron 6.

Anybody home?

An opto isolator is not required.

The Micro 555 is a dual conversion 5 channel full feature RX, is less sensitive an RX than a Electron 6, I honestly don't know without reviewing the specifications, I suspect there quite close.

I’d suggest you return the RX’s to the Hitec Service for a free evaluation.

ok, thank you.
