receiver base load, I was told by someone that you can't use a base load antenna with a synthesized radio. Thats what I am trying to find out for my Tempest.

i am using a base loaded antenna on my turbine Bell230. I have a 9Z tx and the synthesized RX. It works just fine, and there is no way i would be risking a $9000 heli with an antenna set up that did not work 100%


notice the antenna right off of the front windshield (its a deans 2 piece)

I just called Futaba because of what was said, there number is 1-217-398-8970 and they said there has been no problems useing Synth receivers in heli's. I got a little scared there. I just ordered and other receiver for my Tempest. You can go to futaba-rc.com thats there us home site and the number is there to for technical support.

PS

Wiwanczyk, nice 230, I'm going to build a 430 on a 60 mechanics along with a Long ranger III with fly barless heads for that scale look.

Send your Synthesized Rx's to Radio South, they'll fix it right up. I've seen a number of Synthesized Rx's work perfect after getting done up at Radio South.

I have two flying now and have two more on the way and have had no problems at all. I have found a sorce for them thats pretty cheap, not to far off from the 149 price and being from RC Cars I know about crystals and how easy they can be craked and then have intermitant problems that are hard to track. I just find it easier to turn a dial, but I can see how vibration could affect anything as far as electronics.

From what I heard on the Synthesized Rx's is that they are actually out of tune from Futaba which is what causes the lock out and then crash.

Is there any information about the failed 309's regarding how they were padded and installed? When I last met with Todd, (long time ago) he said the 309 was fine.

I see a lot of receivers with little to no padding beyond some foam tape holding them down. I use 1/4 receiver foam wrapped with a KSJ wrapper. For my 309 I use twice the foam pad.

If padded and packaged right, there should be no hi frequency vibration reaching the receiver.

on my turbine 230, vibration is not an issue (there is none) , but i also have beem flying a synth RX on my Xcell SE with a 90 in it ... also no problems ...

I had a raptor 70 locking out a lot a while back, and though it was the synth RX, however, i changed the RX and still had the same problem , so the RX was not the issue there ...

I would recomend sending in any receiver in for a checkup around once per every 2 years .. ( i only do it for the RX s on my more expensive tuff .. )
