Hi

Bought an optic 6 system when in germany, plain vanilla one with 4 standard servos, big receiver and channel 77.
Got home and installed it into the plane, range checked with folded transmitter antenna and all servos were glitching after only a 4-5 meter distance, ofcourse without me touching anything.
So I tested the system outside of the plane, same result. Tried an old hitec dualconversion receiver instead, tried different crystals, different receiver and transmitter batterypacks, even different number and types of servos and nothing changed the result. I am quite sure I narrowed down the problem to the transmitter.

Sent the radio back to germany for repair (I live in sweden) This took some time but finally got it back and instead of repairing it they had sent me a new one.
So I install this new radio into the plane, and do a range check. Well,, better, I can step back about 8-9 meters now before the servos start glitching. But I know that compared to my old basic laser 6 system this is still not a very succesfull rangecheck.

I'd hate to send the radio back to germany again, this takes a very long time and so I'm just wondering it this is a known problem you guys have heard of before? Or is this range problem just normal with the optic 6? If so I there is no point in sending the radio to germany for another replacement.
I have no way of testing range with transmitter antenna fully extended as this would be a groundlevel test and so a rather unfair.

I'm sort of loosing all confidence in hitec radio systems becouse of this.

"compared to my old basic laser 6 system '
there are still many variables e.g.. Which model RX. Does RX have appropriate genuine Hitec single or dual conversion xtal? Was range check with Laser 6 and the other RX in the same model you are now experiencing "short range"?
Perhaps a new model is shielding the signal, refer sub sections "Range check and Range problem solving" and "Receiver - FAQ, guides and aids to best reception.." amongst other sections under "Radio Systems, Accessories, Alterations and FAQ" on my web page, especially
Guide to receivers - and solving apparent RX & "Interference" problems

Hi Alan, thank you for replying.

I use the included dualconversion xtals and the included HFD-08RD with the optic 6 transmitter.
I did suspect the plane at first, after all an electric powered hotliner with long servo extension cables to both tail and wingtips can be tricky.
So the first thing I did after the failed rangecheck was to check the receiver, servo's and so on outside ot the plane instead. I ask a friend to hold the transmitter while I myself walk away with the receiver, a receiver batterypack (no power switch inbetween battery/receiver and tried different batterypacks) ) and a servo or two (tried different servos).

The old laser 6 system uses the supplied rcd 3500 dualconversion receiver and supplied original xtals.
So ofcourse I tested swapping xtals, receivers, and batterypacks between these two systems. and everything seems to work fine except for the optic 6 transmitter. It has a very short range nomatter what I try. While the the Laser 6 has an equally good range with both par of xtals and the HFD-08RD receiver.

But I agree it seems very strange that two new Optic 6 systems should suffer from short range.
So I've been trying to think of something I did wrong, like having the transmitter turned on without extending the antenna. Wich caused something to overheat. Or perhaps using a better quality and higher capacity 8 cell nimh transmitter pack was a bad idea as fully charged it has a marginally higher voltage than the supplied no-name pack, And so mabe it overloaded something.
perhaps I accidentally kinked the receiver antenna cable, but no the receiver works fine with the laser 6 transmitter.

Just can't think of anything else to try or check,

Hi radek, i too have just realized this problem and am thinking to send it back to my LHS for checks.. Seems like im not the only one having this problem.. I've notice short power cut and glitches on my helicopter and was trying to pinpoint the problem.. So far i have 2 electron6 rx and both the receiver can only do range check up till 6 steps away from the optic6 before glitching..

I've taken the Rx out of my heli to try but the results were no where different..
