Hope you are doing better. I have question regarding Dual rate setting shown in the video. Is it done specifically for your application? the part that confused me is the part where you set 30 from 1024 and 70 respectivily from the Global variable

[@BeaversHobby]

@@adityamody8942 Yes, the value is specifically what I want in this application. That's because I assign the trim switch to change (adjust) the global variable directly in the special function. Basically 1 press will increase or decrease it by 1 value. So, I need to set the min and max value on each GV. For example, if you want the dual rates (weight) to go from 0 to 100 then you can change the values, min = 0, max = 100 then assign a switch to adjust the GV. Then assign that GV to weight of the channel (or input) you want.

hello Beaver Can it be used as a multi-transmitter for turbo racing?

[@BeaversHobby]

Unfortunately, no. At least not at the moment. We're gonna have to wait until the Multiprotocol project finally include the turbo racing protocol.

[@Mstom178]

thank you!

[@linushsiao1693]

IS THAT CHASSIS FR? So cool!

[@BeaversHobby]

Yes, it's called BMR-X. It's front motor rear wheel drive and really easy to drift as well. Here's a short review. kzbin.info/www/bejne/oKWXaYKId6edfLs (Don't worry, this one is actually short.)

[@michaelstronghand7584]

I stick with my Radiolink RC4GSV3 that thing is simple and it works 🎉🎉🎉🎉

[@BeaversHobby]

Things that usually take a few button presses to access on RC4GS is a menu within a menu on MT12. Don't get me wrong, MT12 is great if you actually use the open-ended customization effectively. Otherwise it's overly complicated.

[@putulis9474]

Hello mr Beaver, i think about purchasing the mt12 4in1 variant but do you know if the irangex external module is better than the one integrated on the transmitter?

[@BeaversHobby]

It'll work the same. I don't see any difference when using the internal module (of the TX16S) and the external. Basically it depends what will you use the most, ELRS or 4-in-1. If you mainly use it with cars that support 4-in-1 protocols then getting that version is better because you don't have to keep plugging in and out the module. Mostly because it doesn't fit inside the carrying case and you'll have to take the module out when putting the transmitter in the case. I use the ELRS because I install my own receiver and it's one of the fastest protocol available.

[@TheAlros100]

Hi great video. What car is that. I am looking for a small drift car that I can use my own transmitter mt12 and receiver

[@TheAlros100]

Oops just saw you answered this below ! Thanks for great video

[@angelikakurowicka7182]

Would you rather buy the Flysky nb4 or the radiomaster mt12 (4in1) for mini z (standard not the EVO version). Thanks already!!

[@BeaversHobby]

MT12 4-in-1 Multiprotocol version because it will bind to the car directly without having to buy an extra part. Sure, the initial setup can be difficult but it will work great with the car.

[@angelikakurowicka7182]

Thank you for the answer. Will the Radiomaster have the same latency of a Flysky? @@BeaversHobby

[@BeaversHobby]

@@angelikakurowicka7182 The MT12 ELRS version is within 4.16ms difference between it and Flysky NB4 running on AFHDS3. While using with Mini-Z it should have the same latency due to the protocol.

[@angelikakurowicka7182]

Again thank you for your answer!! Think am going for the mt12 (4in1) then. 1 more question! 🙂 what receiver is then recommended to take if i buy a EVO later on. Just the normal one or can you bind up with the flysky one? To have better latency for example? Thank you again!! @@BeaversHobby

[@BeaversHobby]

@@angelikakurowicka7182 To use the MT12 4-in-1 with Mini-Z EVO you'll need the Mini-Z FHSS receiver part number 82041, the one with white antenna for KT-531P. Basically you'll run the same protocol as Kyosho Mini-Z FHSS.

[@tl924]

I used your model back up and for some reason my servo will not work. Dp302V4 Gyro functions and gain is adjusteable but servo will not function.

[@BeaversHobby]

Some servos and gyros that can be programmed via SBUS are not compatible with ELRS receiver. I don't know which one is at fault so you can try and connect the servo directly to the receiver and see if it still works. If so then the problem is at the gyro. If you use a 4 or 5 channel receiver then you can config the output of channel 1 (where you connect the gyro/servo) to pin 4 or 5 on the receiver to avoid the glitch.

[@tl924]

@@BeaversHobby well it's 4into1, agfrc 19kg servo, and Yokomo Dp-302 V4 gyro.

[@BeaversHobby]

@@tl924 Try using only the servo first to see if channel 1 works correctly.

[@tl924]

@@BeaversHobby I did that and it works. Could it be a setting In your backup that's stopping the gyro from working the servo?

[@BeaversHobby]

@@tl924 I'm not sure what could trigger the gyro to not working but I think you should try using the gyro without channel 3 or the gain connected first to see if the gyro works correctly. Also try and plug the servo into channel 3 or whichever you set the VR (for gyro gain) to see if that also works. If the gain adjustment moves the servo then use that channel for the gain adjustment. It might be that the output isn't mapped to the channel correctly in the settings so the gyro stays at 0 gain.

[@BigTomi98]

Hey Beaver! heard your MT12 made a custom sound on startup...how the hell did you do that?! scouted the internet trying to find a way but couldn't. thanks for the help in advance...and great video, very informative!

[@BeaversHobby]

Oh... the Obi-Wan's Hello there. You'll need to name the file hello.wav. Then insert the EdgeTX SD card into your PC, navigate to \SOUNDS\en\SYSTEM and replace the original file with yours. You might need to play around with the bitrate to get it working. The one I use is 16 bit, 16 kHz sampling rate and 250 kb/s bit rate. drive.google.com/file/d/14ZuEQbFtVH7sDa-JgkqpHMpa4i72byiT/view?usp=sharing

[@Alex1066-1]

Hi! I enjoy your very informative and useful videos very much. Followed your upgrade advice with WLtoys cars, it was helpful. Could I ask for help? The car doesn't move backwards, the breaks don't work either. What could be the problem? The forward and turns work perfectly. Thanks in advance!

[@BeaversHobby]

It might be possible that the throttle trim is off centre. The new version shouldn't have that so it should work as long as you don't push or pull the throttle when binding or turning it on. If the problem still persists, try and pull the throttle a bit then bind it to the car. If nothing works then I'm afraid the all in one unit might be faulty.

That's gonna be difficult because there are many parts. I highly recommend you get a manual like Atomic DRZ3 then replicate what they do. www.rcatomic.com/atomic/index.php?main_page=page&id=26&chapter=20

[@fulltang1]

Will this work with the gt55 gyro/rx combos?

[@BeaversHobby]

Only the 4-in-1 version and you'll have to select the AFHDS protocol to use with a receiver like this. www.gt55racing.com/products/gt55racing-flysky-afhds-built-in-gyro-nano-rx?DIST=RUZBGw%3D%3D It doesn't work with the Futaba, Sanwa and NB4 combo with V5 gyro integrated.

[@Limitless_Potato]

I followed your guide and am really liking how everything feels! I do, however, have an issue with the gyro gain with my yokomo v4. It seems my gyro adjustment is somehow also changing the endpoints on the gyro... any solution you may have for this?

[@BeaversHobby]

The gyro doesn't reach the same angle after adjusting gain sounds normal. That's the same with or without EPA. You can check if the EPA is still the same by steering the car while it's stationary and see if it can still reach the maximum steering after adjusting gain. If you turn the gain down and somehow you can't steer to the max while it's not moving then there's a problem and maybe you'll need to reset the gyro or try another channel/output frequency.

[@Limitless_Potato]

@BeaversHobby yes this is what I mean. The epa changes along with the gain. The higher the gain, the higher the endpoints. I have the channel at 333hz atm

[@BeaversHobby]

@@Limitless_Potato That is so weird. Usually the 2 are set separately and EPA is controlled outside of the dial. There's nothing on the manual either. Can you try using it without the gain channel connected and adjust it on the dial on the gyro unit? If the problem still persists on that dial too then it might be faulty or it just doesn't really like ELRS receiver.

[@Limitless_Potato]

@BeaversHobby I checked the settings. Looks like on ch3 x on the graph adjust end points and y adjust the gain

[@BeaversHobby]

@@Limitless_Potato A channel only outputs 1 axis. Basically it outputs the pulse from 1000 to 2000 where 1500 is the neutral or centre. The graph in the menu shows x axis as the input value and y axis as the output value.

Im looking for mini z drift tyres that are hard rubber not plastic so lower noise. Any ideas which? Actualy for wl toys k series and 22mm prefered

[@BeaversHobby]

There's one manufacture from Greece that does it. It also increases the grip as far as I know. There are more effective ways to reduce the noise. As long as there are tyres spinning there will be noise so one way to do is to dampen the surface. Use short hair carpet/office carpet or moketa and the noise will go away. If you have a vinyl drift track then put some EVA mats or freight mats under the vinyl sheet will help a lot.
