Can you change the shift select on a Futaba 9CHP so it will work with a JR radio?

Thanks!

Nope. As far as I know, Hitech is the only mainstream company that offers this.
Polk may as well though.

Airtronics offers the feature.

Polk's Hobbies most definitely does support it - but they aren't mainstream (yet).

I have seen somewhere that some JR radios support this as well. I think they call it INV-PPM. Or maybe I'm thinking of Airtronics...

Futaba is likely to NEVER support positive shift on 72Mhz, since they are the SOURCE of the issue. Overseas, everyone uses positive shift (including Futaba).

The leading theory is they implemented negative shift to try to force brand loyalty... Just like JR does by having it's charging receptacle with reversed polarity of everyone else.

Positive and negative shift is a function of the 72MHz band we fly on. It is not a function of 40 and 35MHz products used overseas.

It's not a theory Strato, it's just a simple fact =>

There's a shift inverter kit for the 8U that's suppose to be usable in a 9C, fwiw:

Until someone from Futaba admits it, it is only speculation.And from what I can tell, it's also unique to North America. A while back I saw a thread where someone in another country flies on 72Mhz, and +ve / -ve shift is not an issue.
