I ran for the second time with my "new to me" M11X. I really like this transmitter. My range issue has been fixed with the new internal antenna and I was able to recalibrate my Justock ESC's to run more brake. I use the throttle trim (I have it set to both switches above my left thumb) to adjust the brake when I'm running.

Bump anyone got any info ?

First thought would be the RX antennas may be damaged- kinks, nicks etc. Replacements are about $10 each on ebay.

I was offered a free M11X. Does anyone know what receivers will work with it?

FHSS. FHSS-2, and FHSS-3 receivers

So any of them work, they don't have to be specifically for the m11x then? Is there a difference that I will really notice if I go say for an FHSS versus a FHSS-3?

As long as the receiver has any of those protocols it will work with the m11x, it doesn't have to be specific to the m11x. And the main difference would be speed. The FHSS-3 receivers will be a lot faster than the old FHSS receivers. So I would prefer FHSS-3 for racing and if just bashing the FHSS-2 is more than enough.

How do I change from fh3 to FH2?
