I am looking into replacing my Takuma remote with a Flipsky VX3. In another thread, I shared my findings for anyone else interested in doing the same. I note that the Takuma ESC uses PWM and am concerned that the pulse width duration used by Takuma is not the standard 1ms - 2ms used ny Flipsky and Maytech. Any thoughts?
Also, is there a manual floating around for the Flipsky VX3. I a am curious whether one can set “gears” (speed limits). Like the 3 you can set on the Maytech
Could i use an arduino to test the PPM range of the ESC?
If not the same range, could one use an arduino / esp32…to modify the signal?
Could use a servo tester?
Good suggestion but I believe servos use slightly different PWM signals.
Further reading has kinda confirmed that 1ms -2ms is pretty standard for a non braked throttle. However it seems that there is also the issue of frequency. The frequency in RC is 50Hz or once every 20ms. So we are not really using a duty cycle type signal, rather a true digital signal. Apparently a clock signal is not required because the start if each successive signal is sufficient for timing.
I half understand the above but would love some confirmation before i sink anymore money into my Takuma
I am sure there is a guru on this forum that can clear this up for me.
Not a manual but it might help. At 3 minutes in it shows the process to alter ‘speed control” H,M amd L
This might also help
Thanks @foilguy. I saw those two posts. Will revisit them.
I asked Maytech for support and whomever responded had no idea. They told me the frequency of the PWM signal was 2.4GHZ which is obviously the carrier frequency of the remote.
I spent some time on CHATGPT and have all but convinced myself that 1-2ms high signal with a frequency of 50Hz is the go. I also have an arduino script to read the signal from the receiver and modify it.
Hopefully get a response from either Naytech or FlipSky. Whoever gives the first sensible response, will get my business.
May I ask why you want/need “gears”?
Wouldn’t you change the ESC as well ? Doing so, you would master the whole chain between the user hand and the motor.
Honestly, don’t want to invest in this board. Being its a Takuma, the board is not that great and the motor is rated at 3KW, so I just bwant to be able to foil alongside my daughter when she hijacks my Fliteboard.
The way the Fliteboard works is you set the startup “gear” (top speed) between 1 and 12. Usualy about 3 or 4 then pull the trigger all the way in and adjust the speed by “shifting gear”. Of course youy can regulate the speed with the trigger. Its really easy for beginners.
The Takuma has a wheel on top of the controller that effectively has infinite gears. In fact the Takuma trigger is an on/off switch.
I’ve not had a chance to experience a Flite controller so can’t really comment on it.
The VX3 I find very easy to use as I can add or reduce speed instantaneously with the throttle. I use that capability to make minor foiling height corrections as I go along especially during sharp turns.
Their “speed control” really only has two useful levels M and H as L doesn’t have enough to get me up on foil. It could be useful in teaching someone who is fearful as it does move the board through the water allowing the rider to get used to turning etc.
I tried M for a bit but reverted to H as I like having the full capability of my system on hand. M provides most of the capability it’s just a bit more “mellow” on how it does that.
If you mean can you have throttle squeezed in and then press the mode button to switch values - I’m not sure as I’ve never tried
What I do is power on remote - unlock it and then pick a “ speed” for that session.
I just did sort of a test as I only had vx3 on - not connected to VESC and it won’t switch mode until throttle is released
Remote always powers on in H goes to M then L then back to H
