JR 347 and Hitec Electron 6 poblem
Hi everybody.
A couple of weeks ago I purchased an Align Trex ccpm. The heli is pretty good so far except for the flex in the head and flybar assembly which I am slowly but surely remedying with aluminum upgrades (I do have to budget myself otherwise I'd spend my entire paycheck on RC stuff). I also like the fact that a crash costs me $30 versus the $300-400 I usually spend when I wad up my Xcell. Anyways, I've spent the last two weeks asking every employee at almost every hobbyshop located within 30 miles of me why I can't get the Hitec Electron 6 to work with my JR 347. I've tried everything I can think of. PPM, PCM, Hitec crystals, JR crystals, negative shift (Futaba/Hitec), positive shift (JR/Airtronics) and nomatter what I do it is still not registering with the Rx. I am running HS-56's and a 401 (if that matters) so I know it's not the lead arangement in the plugs for the servos. Any ideas? Also does JR even make a 6ch rx that will fit in the Trex? Thanks....Jesse

RE: JR 347 and Hitec Electron 6 poblem
Hi,
From the days when I did more RC, I was using Futaba, Hitec, Sanwa (Airtronics) and JR Rx's with my JR X-347 and X-388
The gear must have it's own manufacture crystal.
That is the X-347 MUST have a JR crystal, and the Hitex Rx MUST have a Hitec crystal.
Also, from what I understand, PCM is NOT cpmpatable across different bands, so u can only use a non-JR PPM Rx with the X-347, with it set to PPM mode.

RE: JR 347 and Hitec Electron 6 poblem
Yep... put a Hitec dual conversion crystal in the RX, leave the original JR xtal (that came with your TX) in the TX, if the Electron-6 doesn't specify it's shift (although it should), it probably negative shift (Hitec/Futaba)... if it is positive shift, it will say so (JR, Airtronics). Now, if the Electron-6 is negative shift, then your JR TX must be able to transmit in negative shift PPM mode, otherwise it will never work with negative shift Electron-6.
I'm not familiar with your TX so I don't know if it has selectable shift (+/-)...

I have even just recently activated the eCCPM modes "hidden" in the X-347's programming and am using it to fly my Caliber 30 with electronic mixing.

RE: JR 347 and Hitec Electron 6 poblem
oh yeah that's right, the electron6 is a dual conversion Rx, that means it needs a dual conversion xtal.
also, JR makes 7 channel micro rx. that's the R700 (ppm) or R770 (pcm). it's very small
. i love my r770, i wouldnt trade it for anything else lol

RE: JR 347 and Hitec Electron 6 poblem
I have already tried a hitec dual conversion crystal with no results. Right now I have a positive shift Rx. I have already tried both positive and negative shift. Now the Dual conversion Xstal is a different story but I think the guys at the hobbyshop would have a little more sense then that. Aren't all HItec crystals Dual Conversion? I'll have to try that next.
BTW the eCCPM mode kept me frustrated for a few days. I don't have my manual since it is in storage so it's made things a little difficult. I found a post using google in a forum that explaned it very well. It just took a few times to get the gear switch rythm down.

RE: JR 347 and Hitec Electron 6 poblem
Hitec has both dual conversion and single conversion crystals, they are different, you can tell by the color on the tag...

RE: JR 347 and Hitec Electron 6 poblem
I think we have a winner!!!! My crystal is green. The local idiot at the LHS guaranteed it was dual conversion since, according to him, Hitec only does single conversion for car stuff. They better let me return it. Luckly they know me pretty well. Just like Bob I have to throw away my receipts and then claim I bought everything on Ebay at 1/10 the price!!! If I remember correctly when I bought my TRex it went something like "I won the auction for only $50"[
. I think she's catching on by now though.

RE: JR 347 and Hitec Electron 6 poblem
OK new problem. I got the receiver to work fine but now I can't figure out what channel and switch/knob adjust the gain on my 401. I swear I should have just left my full size receiver strapped to the bottom!! I have the gain plug on ch6/bat on the receiver. Now can anyone tell me which aux channel it is on my Tx. I REALLY wish my manual wasn't buried under a rediculous amount of boxes. Also, since my 401 manual is buried as well, can anyone tell me if I can visually see in the LED on the gyro if my switch flipping and knob turning is adjusting anything or do I have to just keep popping it up into a hover. I'm really close to just ripping off the 401 and buying a 240 (it would make my life so much easier).

RE: JR 347 and Hitec Electron 6 poblem
Ok,
The main lead of the gyro is plugged into the rudder channel, and the gain control lead is pligged into the gear channel (usually 6).
Then, going into radio setup, you adjust the travel adjust of the gear channel to change the sensitivity.
Usually, travel is defaulting to +100% and -100%.
Change these values to change sensitivity in the two modes of the gyro..
