Mentat · 10:48 PM

Hey guys, i just got thru setting up a Jammin X1 truggy and my buddy only has a 3 Channel Futaba radio. Its kinda glitchy. I have 1 fereite ring wrapped around the ESC to Receiver wire. First off is that the best place for the ring? Secondly what can we do about the Glitchyness? Would AM be less Glitchy? Thoughts, Suggestions!! SETUP PICS below

Move your RX farther away from your power wires

Also, braid your motor wires as well.

Thats what i said....

Pffftttt....

yeah, i know its the FM radio. I connected my 2.4ghz to it and ZERO issues. I added another fereite ring and that help some. Where would i mount the ESC? to the rear?

Behind the battery tray is the usual spot.

get a big ferrite ring and wrap it 5 or 6 time rather than having two little ones

Move your battery tray forward and drop your ESC behind it, and then move your RX on top of your steering upper plate (the carbon fiber one).

That would help quite a bit.

You'll be surprised how much placement matters. Even my Spektrum glitched sometimes when I had my receiver right next to my ESC and almost literally below my motor. Moved it and it works fine.

If you can't or don't want to move your battery forward and mount the esc behind it, make a new center diff top plate or extension that will mount the esc more towards the rear of the truck. I also second moving the reciever further forward and twisting the motor wires up to look like a candy cane.

I'd also try to keep the esc reciever wire away from the battery wires as much as possible. In the pics it looks to be too close and runs parrallel to the pos wire a little too much for my liking, I'd zip tie it to the chassis to get it away and prevent damage. This won't have as much of an effect as the motor wires but every little bit helps.

I moved mine back slightly and it made a huge difference

For the record, AM is bad, terrible for glitching ( 99% of people would agree).
FM is usually pretty good, I run 89mhz Fm and no real issues.
2.4ghz is generally seen as the perfect frequency/ radio type to run, and prices are pretty damn good these days, just depends how many bells and whistles you require..

well, we used an old AM setup and it works flawlessly, go figure.

I mount my RX as far away from the ESC as possible and I run an AM TX/RX. I glitch occassionally, but the frequency in my truggy seems to be common in my area as I've lost control of it the most often out of all my trucks.
Regarding why the FM glitched more...it just happens that the spurs of the MMM's frequency is in the operating band of that particular FM module. He can try another FM module/frequency. Otherwise, if the AM works, stick with it until he can afford 2.4GHz.
