The oscillations come from the spring on your radio wheel and the speed of the servo. The time it takes for the signal to travel from radio to car will not affect the vibrations of the wheels, because regardless of that time it will still perform the action once it receives the signal to do so.
Your video really doesn't show much at all (apart from you telling us / claiming, repeatedly) because you are using completely different setups (for example, have you measured the return vibration amplitude or frequency of the MT4 wheel? it's likely not the same). In my experience most reasonably fast systems from both Futaba and Sanwa will replicate wheel return vibrations - if you want to actually display the difference you need to be more scientific - eg. setting up actual latency and refresh-rate measurements. The difference between FHSS3, FHSS4 and faster are very difficult to see with the naked eye on realtime video. That doesn't mean the difference is not perceivable when driving - it certainly is. But to actually show this, at the very least some high-framerate slow motion video of the vibration tracing (between radio wheel and servo) would be useful. I'm not saying your claims are wrong - just that your claims are not adequately proved or displayed here.
Good points. Actual test will be on the racetrack with lap times, which I should have in a couple of weeks weather permitting. All I can say is that on the track, the responsiveness is noticeable. Right now I don't even want to drive my MT4 controlled cars anymore after experiencing the speed of the M17 on the track. MT4 feels like driving a bus :D
@@rccartips Thanks for not taking it the wrong way and also for checking out my video, both appreciated. I have no doubt the MT4 is noticeably not as responsive as the M17, it's quite old now and uses FHSS-3 (also, are you using the SHR mode on your MT4?). But the MT-S is a budget radio using the faster FHSS-4 protocol (same as M12-S) and it would be interesting to see how the M17 compares to that. I'd like to upgrade my ancient gear soon, so I'm waiting to see some data before getting a current budget Sanwa FHSS-4 radio, or waiting for the "poor man's version" of the M17. Thanks for sharing, hopefully you have a chance to compare more, perhaps with same/similar servo.
Here's the slow mo at 20% speed, can still see some delay on the M17, maybe my hand is ultra instinct super fast :D ruclips.net/video/_RQflJVXSJc/видео.html

Yup! I hate that people don't have that common sense and have been doing this dumb test on RUclips for years.
I was just researching this control. Perfect timing
Expensive, but fast :)
I race off road and the antenna wire helps reliability and helps whit vibrates from the nitro engine
What rx type did u used on your video
RX 491 receiver
same servos on both cars?
Nope. Futaba 9550 on the xray.
Added a slow motion video :) ruclips.net/video/_RQflJVXSJc/видео.html
are you racing on road in the philippines? i cant find any on road tracks
Yes. STR raceway in Sunvalley Village.
Is this the version 1.01.02 of the M17?
Sorry I don't know the version. All I know it has been updated and bugs fixed.
the old one is better... it fixes your jittery hands.

It looks like mt4 servo return speed was slowed way down, wasn't even oscillating. at normal settings it certainly would oscillate.
@@rccartips i can drive a bus and still be faster than you on the road!
