Attention 14MZ and 12Z users
We have had a few emails about concerns with the use of the 14/12 radio’s and the TJPro or Revmax.
Owners of these radios are well aware of Futaba’s FAQ’s, write ups and forum topics related to these G3 RX’s and the difficulties people have had with its increased RF sensitivity. All heli’s have a certain amount of RF generated by them. With all the RX’s that we used previous to the G3, it was not a problem.
Out of precaution and because of the highly sensitive nature of these new G3 receivers to RF interference and after reading on Futaba’s website (see links and info from Futaba’s site below) about recommendations of filtering, we are willing to provide ferrite rings free of charge to customers that have already purchased our products and use the 14/12 radio’s to help keep our products from possibly interfering with it.
After you receive the ring, just wrap the throttle and Aux leads through the ring close to the RX for RF filtering.
Based on experience and also right on the top of Futaba’s list of things to watch is antenna routing. Get it out of the canopy with as short a route as possible and keep it away from other electronics, servo leads, and metal/carbon objects.
Another great technique to prevent interference is to braid your servo and aux leads. It is basically turning the leads into twisted pairs, which is common practice in the electronics field for fighting RF noise.
Please send me an email with your Name, Address and Serial Number off the 14Mz/12z to kurt@modelavionics.com and we will send you a ferrite ring.
Futaba’s FAQ’s for the 14MZ and 12Z Radio Systems
http://www.14mz.com/faq/faq-14mz.html
http://www.futaba-rc.com/faq/faq-12z.html
The two Frequently Asked Questions that we suggest you look at are in the General FAQ section for both Radios.
They are easy to spot since they are both currently the first two FAQ’s for each Radio.
1. The first, asks about cutting the G3’s antenna.
2. The second, asks about What’s wrong with G3 Receiver, and negative comments on RC forums.
Thank you,
