It also lets air out which can make a difference with ballooning. I know what you're thinking but I've actually seen this with a freshly glued set of tires I spun up on the bench to check. They all ballooned a little differently and one significantly more than the others and was sort of triangular. After venting they all ballooned in a matching way and the "triangular" one ballooned in a proper 'U" shape instead of a "v" shape.

I vent the rim. During wet weather, I cover the vent. 👍

Ok my friend this is the radio I’m looking at, what do you all think

Sweet I don’t wanna go crazy on a radio this several here have suggested, just don’t want to spend $500 like on my aircraft radio much less the $100 plus for each 8-10 channel receivers I have to use

Interesting - that may explain why some tyres look more like pizza cutter Vs balloons? 🤔

The only set of tyres I own that balloon with me now are the stock XTR tyres. They're nice off road and on grass, so I'll live with it. The wheels are all balanced up and that makes a huge difference.

My Prolines, James, Sweeps Truggy size tyres are wheel vented and 'prepared' to reduce ballooning.

My Proline 40 series on 22mm hubs are also 'prepared' with wheel vents and well balanced.

I think the thing to remember is that putting holes in tyres not only lets water in/out more readily, but dirt, dust and sand. Vented tyres on a 1/10th buggy at a carpet national may make sense, but not so much on a 1/8th basher Truggy off road on all manner of crap. 😅

The joy of vented tyres off road:

There's no right or wrong to this - it's personal choice. But choose wisely according to your use.

And did I mention - balance your wheels? 😝

I have one. Great radio, amazing hardware quality for the money. But it's NOT "plug and play" like a Flysky or a Radiolink radio. Like all EdgeTX radios it is a tinkerers radio. If you want somthing you can just take out of the box and use then it's probably not what you want.

If you get the Express LRS version then YOU MUST update the firmware on the receivers and transmitter module inside the radio to the latest firmware (V3.51 or later). The V3.1 firmware has a dangerous bug with PWM receivers where it rarely can lock you out while holding the PWM channels at the last position ignoring failsafes. This will continue fort as long as 10 seconds until the watchdog determines that the receiver has frozen and reboots the receiver reestablishing the link.

This is NOT the same as the transmitter firmware (Edge TX, though you should update to the latest too). The radio (the MT12) and the transmitter part (the internal radio module) are separate systems that each have to be updated. To update the radio module you download the firmware file and place it in the /firmware directory on the MT12's SD card and then update the module from within the EdgeTX operating system (there are YouTube videos on this)

The easiest way to update your receiver is with wi-fi mode, if the receiver sits for longer than 60 seconds with no connection (radio not turned on) it goes into wi-fi mode and will appear as a wi-fi device to your PC or phone. You then just connect to it and then navigate to it's web page address with a browser where you can adjust all it's settings and update it's firmware. I would also reccomend setting a bind phrase (the uniqe identifier for your transmitter and recievers) to a 32 character long random string generated by random.org and NOT an "easily remembered word or phrase" as the Express LRS tutorial pages tell you to, that is a terrible idea because if two transmitters or recievers have the same bind phrase then they will conflict. Just put it in a text file and save it somwhere so you don't forget it.

You can also use USB to update the Express LRS recievers but I could never get it to work.

Note also that the PWM bug is not Radiomaster's fault it affects all ELRS PWM recievers by any manufactuerer, it does not affect serial recievers. the bug is with the firmware from the Express LRS development team. Radiomaster does not do software development they just make hardware that runs on open source software.

Express LRS has basically the longest range of any current RC link protocol. It was developed by and for FPV drone guys. The range at 100mw is insanely long somthing like 20km under ideal conditions and it can output up to 250mw. Some peoeple have gotte over 100km out of it at full power with a directional antenna. For line of site R/C I would leave it at the default 100mw and set it to "dynamic" where it adjusts output power to maintain the link.

I think that's less of an issue with on-road tires. How big are the vents? I use a 2mm drill bit and it's plenty.

Also "pizza cutter" is a good description, that effect went away as soon as the tires were vented and they all ballooned by the same amount in a proper round profile.

Most wheels are already vented at the heavier side with 1-2mm hole.

Some manufacturers prefer not to vent their wheel or tyres and leave it entirely for the user to decide. The Kagama LE is one such example - and in the recent live event, Luke discussed the reasoning.

There are valid pros and cons to allowing tyres to breathe. If users choose to vent the tyre rather than the wheel/rim - it's a one-way decision.

If users choose to vent just the wheel/rim - they can generally be sealed to the elements on wet days or for use on dirt tracks.

Ballooning tyres can pull away from the rim regardless of vents and when they do, it's highly likely that the tyre will rip apart.

Ingress of dirt and/or water causes entirely different problems. Severe out of balance wheels and tyres will cause other mechanical failures and negatively impact performance.

I believe the Crossfire system still has the longer range, in real world terms, due to better penetration at 865mhz or 915mhz frequencies - simply down to the physics of the wave. It's still used for scientific purposes - as far as I know.

IMG_20201119_133016.webp

The other thing of course is that the full fat version can transmit upto 2000mW.

Obviously, this will far exceed what most FPV systems' video range is, but the fact remains.

Express LRS is open source and much cheaper and has a 900mhz option, so I suppose at that frequency the 2 are essentially the same thing - one open source, the other proprietary.

At 2.4ghz, the Express LRS has extremely low latency (5ms) and 1000hz refresh rate. Plus being open source, it's constantly being updated, where as the 'industry standard' Crossfire is more......sedatary.

The crossfire setup I have to say was fairly streamlined and slick to get up and running. I love the little OLED screen on the full module! 😎🤩

Whilst not difficult according to users, Express LRS definitely takes more time to get sorted. Joshua Bardwell is a huge fan, so it must be good!

Extremely helpful and informative post right here ☝️

Getting stuff setup on these kind of radios is a bit of a faff when you're used to KO, Sanwa, Futaba, Spektrum etc but it's well worth the effort.

I'm still using OpenTX on my Taranis SE. I've been delaying the inevitable switch over to newer stuff because I hate fixing things that aren't broken.

I much prefer the mechanical side of things over fussing with firmware and downloads and rooting etc - but it's definitely an essential part of hobby people have to wrap their heads around when getting into drones etc.

Joshua Bardwell has been an excellent source. 🤣
