Rx482 range issue.
 
Hi guys. Bit of a noob here.
have a yokomo bd8, was running a sanwa rx472 reciever with a sanwa mt4. I've replaced the reciever with a new rx482 and now the car runs out of range on my local Onroad track. Isn't a very big track and had no issues with my old reciever.
Any ideas on what's the problem? (Others at the same track have no issues with the same reciever)
Thanks

Maybe you should try a different mounting. The standup part of the receiver contains the antenna, if it is close against some metal/carbon or the transponder it can suffer from a weak signal

Nicko451 07-26-2018 01:46 AM

Thanks for the reply. I've remounted it. Will have to wait for daylight to test.

Let us know if you fixed it.

Was hard to tell as I always drive at a track and just tested it out sidey house (not sure the difference me standing on ground level compared to at the track) the car drove about 110m before it lost range. Seemed to be alot less distance at the track.

Do you use Life or lipo batteries?

HaulinBass 07-27-2018 07:19 PM

Was it indoors? Steel building? I only have issues outdoors when blocked by a steel structure like a seacan. I have my transponder attached to the standup part of the antenna just beside the bind button

Just making sure but does your transmitter have full batteries?

Nicko451 07-28-2018 10:38 PM

It's outdoor. Others race there with the same reciever. Yeah full batteries. I'll be going there on Thursday to test again.

Went to the track today after re soldering my ESC and motor (tabs were loose and a messy solder job has them touching)

It was much better but still went out of range in one spot on the track, which was strange as it was not the part of the track which was the most distance away.

I run the same receiver on a large outdoor track with no problems.

You should post a picture of your install

yes, I know the reciever is capable. Trying to figure out my issue.

It's not letting me upload from mobile for some reason.
Pretty standard layout. For a touring car.

belewis01 08-04-2018 10:04 AM

I think you need 9 posts before the forum lets you post pictures. Didn't see your post count before I suggested a picture.

do you run a esc bec or a ubec. whats its voltage and are the rx plug for it ok?

Standard touring car setup. Everything is compatible.

platgof 08-04-2018 05:36 PM

I think you got it wet somehow, or wiring. These are very good rx's. The only problem I had was when I caked it in mud, that was bad. But I kept blowing the mud and water out and it came back to life.

JC3 08-04-2018 07:11 PM

Take it apart and look closely inside for anything unusual.

Nicko451 08-04-2018 07:51 PM

I'll have a look inside jc3.
it had issues from brand new, not a chance it's ever gotten wet since I've had it. Wires were all done by a RC shop.

windellmc 08-06-2018 02:42 PM

Could just be a bad receiver. Maybe the internal antenna is bad or disconnected. Does anyone at your track have a spare you can try?

Nicko451 08-07-2018 02:00 AM

I have a spare that I've tried. Went out today with 2 cars, 2 recievers and could not drive out of a 15m radius without losing signal. All I can think now is my transmittter.

Nicko451 08-07-2018 09:57 PM

I'm running a sanwa mt4 for the record .

seems likely. If you want to confirm need to ty another transmitter with your car/receiver. Make sure your transmitter doesn’t have a low power option. I think some countries (France maybe?) limit the transmitter power. If you have a low power model you may be stuck with the big antenna.

Nicko451 08-09-2018 05:42 PM

I've not heard of low power option. Got a friend sending me his transmitter to test.

Roelof 08-09-2018 11:54 PM

In Europe for DSSS systems there is a law that it may not transmit with more than 10mW power while in the US it is 100mW. I believe with FHSS it is on both continents 100mW
