So good news John is that this is the best review of m9 as you actually do hands-on. This remark about roller blocked when screen is tilted is priceless. Bad news is: since you don’t do much ‘wow’ and ‘amazing” sub base will grow slower. :) Well done.
36:02 Regarding those weird (992) SBUS readings?... I figured it out -- (and they now make perfect sense.) DISCUSSION: The SBUS numbers displayed by the ToolkitRC devices are in units of: _counts_ (CNTS). The SBUS communication protocol, (invented by Futaba,) represents each channel data value as an 11-bit integer number having 2048 distinct values ranging from 0 to 2047 _counts._ It turns out that each microsecond of the PWM pulse width (USEC) is 1.6 CNTS. To clearly see this, set up the OUTPUTS section of your OpenTX/EdgeTX controller as follows: Subtrim = 0, Min = -125.0, Max = +125.0, and PPM Center to 1520. To set the +/-125 travel limits, you will first need to check the "Extended Limits" checkbox on the MODEL SETUP page. (Note that Futaba historically defined the servo travel center position to be: 1520 µsec.) These settings result in channel output PWM pulse width values that range from 880 to 2160 µsec with a center of 1520 µsec. When you connect the SBUS output of a bound RX to the ToolkitRC input and twiddle the sticks, you will see that the displayed CNTS values will vary from 0 to 2047 with a center value of 1024. Mystery solved! SUMMARY: To compute PWM pulse width (USECS) from displayed CNTS, the equation is: USECS = CNTS * 0.625 + 880. To realize the full range of the 11-bit SBUS channel data, the travel limits must be extended to +/-125% and the PPM center must be set to 1520 µsec. Cheers!
I just bought one of these chargers. It seems to work OK except it doesn't announce charge completion. Any idea what could be wrong? I have tried changing the operation, announce, and warning sound settings to high, medium, etc.
Excellent indepth review! I really like the USB-C PD feature on this, you could actually fieldcharge your laptop with this using a lipo, and the USB info page is really neat.
@ToolkitRC when will you have bluetooth and a mobile app like the SkyRC charger. M6d, I notice balance has some issues when one cell gets away from the others it doesn't hold it on full balance, so it hits 4.2 well ahead of the other cells and reduces the overall cell charge rate. End of charge can then take quite a while to finish. :-(
Great video. I got my few days ago. Tested most of the "extra" features,working great. But unfortunately mine balance port is not working. When I connect battery (3cell),and balance port in correct order,it reads only No.1 cell. If I connect it from the opposite side,it reads 6 cells,but not in correct order. Tried calibration procedure,not possible on "missing (0,0 v reading cells)". Any idea what can be the problem?
Balance ports on chargers are pretty much solid state. Try a different battery perhaps? Just to make sure it's not a defect with the balance leads on the one you tested. There are no adjustments for voltage readings on balance ports.
@@RCVideoReviews I have tried many batteries. I have even build 8 cell battery pack to test it. Strange. On 3 and 4 cells,it reads only No.1 cell. On 6 cell,it reads No.1.4,6. On 8 cell battery,it reads No. 1,2,3,4,6,7,8...
Have you trie the signal output function to test/drive servos? I have tried this function on several different servos both analog and digital and haven't had a good servo response. This has been especially true when using the Auto functions whee the servos become very erratic or stuck in a position.
I just received my m9, and on the second day, it only boots up to the voltage calibration screen and doesn't let me do anything, has anyone seen this issue?
Great review John. Very informative. Covered all the features well.
Thanks Dave.
Thanks for the calibration reminder.
Any time!

Thanks Robert. I appreciate the sentiment. It may be a long climb but I’m trying to do things the right way. Appreciate your engagement. Thank you.

Love your reviews.👍🤠
Awesome, thank you!

Great job John. Nice little tool.
Thank you Bill. Good to hear from you.

Yes. I like how so many Toolkit products are now providing USB charge ports. Very handy.

That sounds like a defective charger then. I'd try and get it replaced. There are no configuration options for the balance port that I am aware of.
Thanks for the review.
My pleasure!
I like it not so much as a charger but for the other features. Unfortunately I have not seen it for sale anywhere
hi
do you have the htrc ht208 ? to compare them ?
thanks
I do not.

Sounds like a stuck button. Do you hear/feel the detent on the jog dial when you press down?
"Main port disconnected"
Toolkitrc m9 ошибка
Что делать?
Not sure. Make sure your input voltage is sufficient...?
