Honestly I didn't know KO had a synth system in place.
Also your glitching can be casues by many different factors.
My Yokomo SD glitched so bad I almost quit RC all together.
Luckly some really nice people showed me what was what.
If you are running a Carbon fiber chassis then the factors just jumped up another three clicks...
Not even a synth system can solve some of the issues.
I thought the same as you and bought the Novak switch and the glitching still persisted. So really what we need to do is figure out what is casueing the glitching....
First anything Grafite-Carbon Fiber-of both rubbing can cause glitching.
The antenna touching a Grafite-Carbon FIber part can cause glitching.
Running Carbon Fiber-Grafite chassis can cause glitching.....
AND ON AND ON AND ON.
Some really good items to look into are radio noice redusers (ferrit coils) that you put on your ESC and Servo wires to eliminate radio interferance going out to your componants.
Also there are clip on Ferrit coils that go on your motor wires, Futaba and Much more racing have those...
Yokomo has a Noise Killer kit.
Here is a link to the Yokomo kit.
You put the noise killer between your Esc and receiver.
The silver tape is to go around your receiver to kill any chance of a glitch I just used ferrit coils and my glitching stopped.
Unless of corse someone turns on their radio....
Here is a lick of how I used ferrit coils on my Yok SD.
Hope this helps
Besides it is a whole lot cheeper than a $300 radio.
