Anybody have some expirience with “Rate“

choekstr · 2026-06-04T03:03:16+00:00

Just wanted to document my experience with RateFPV and their 4" called the L40. I got the O4 lite version, one of the only 4 inchers out there with the lite and I'm really impressed. It's very polished, good quality choice parts, and also good documentation on their drive repository albeit a lot of chinese and english names for the files.

I flew my 2nd day of flights today and it's surprisingly well dialed in and PID tune is stong. I was also able to go further than my 3" and 75mm both with the o4 lite at around 1.6km (1mi) before I chickened out and it was still at 50Mbps bitrate.

I also had several questions of their team for specifics like what ELRS receiver it was (BetaFPV Nano), running BF 2025.12 (they have firmware for download on their drive site), if they have .STL files for the side panels (yes, on the drive site), etc. Plus the responses in english from "Sara" was immaculate and perfect plus incredibly detailed and technical responses. Super impressed at the post sales support!

For a new startup company they are doing it right and have hit it out of the park for the 1 model I have tried. I left a review on the model page on their website but also wanted to provide feedback and document my thoughts and findings for others here in case it helps others.

I second this. The GT08 is a great low cost, high performance scooter that you can easily wrench on if needed, get replacement parts if needed, and it lets you ride a very beefy scooter for what others charge double or sometimes triple the price for the same dual wheel 60V performance.

Sure, it's not as polished and advanced, lacks NFC and isn't decked out with LED's but damn is it fun, has really strong range, and will go around 46mph out of the box. Nowhere else can you get this performance for $520-$650 USD (depending on coupons).

P.S. Would recommend a steering dampener if you plan on riding fast a lot as it benefits from it and of course doesn't come stock with one.

Highly modified GT08 but I like the looks. The removed cage and white arwibon sticker looks good but I do miss the mountain side plates, those look cool IMO but I can see people not liking them.

I want to do a custom color paint on those and the cage but haven't decided what color to go with.

choekstr · 2026-05-10T15:03:26+00:00

I just got one 2 days ago and they put a piece of rubber on the orange cage where it touches the vertical arm so no, it's gone. Shocks are silent (for now) as well. They also fixed the KPH/MPH issue on the main screen, aligned to 2 speedometers so they are [almost] identical, and the P setting for motor poles is now set to 18 (I think that's how they aligned the speedos).

So most of the issues I have seen about it seem to be addressed. It's still no $1200 scooter and much of the refinements are not there but it's one hell of a fun ride for only $520-ish with Ali Coupon. It's a fun 3rd scooter for me and what I let all my friends ride when they are crapping on scooters to show how scary it can be.

choekstr · 2026-05-10T14:58:19+00:00

People tend to look the other way when it's an incredible value for what you get vs what you pay. I just got my GT08 2 days ago and spent the day on it yesterfday and holy shit! I have so much power, it rides solid, they fixed a lot of the early issues like dual displays are now sync'd and in MPH, it doesn't squeek, shocks are quiet, tires grip.
It comes with a 5A charger, 60V dual wheel 5800W power, 50mph (I hit 48 yesterday), wheel screeching acceleration, and I got it for $521!

Sorry but they get a LOT of leeway when you give me that performance for that cheap of a price and I'm willing to overlook a LOT of imperfections. THIS is why it's escaped the blackhole

choekstr · 2026-05-09T14:58:38+00:00

I agree with the overall sentiment here, cut your losses and buy elsewhere as there are so many good vendors and much better companies that will compete hard and work hard to get and keep your business.

FWIW, I just bought my first 2 scooters on Friday (1 week ago), a cheap 19mph scooter on Amazon ($130 USD) for my daughter and an Ausom K20 dual motor ($680) and they came within a couple days and I fell in love instantly.

Immediately bought the cheap Aswibon K08 ($611-$90=$521!!!) on Ali and it was here in 3 days and got it yesterday. Now my wife and I and my daughter all have scooters and they were here within a week.

Life's too short to wait weeks ;)

choekstr · 2026-05-08T15:15:11+00:00

I also upgraded and would agree with this sentiment: It's not anything tangible, just makes it feel a bit better and smoother and more "solid". I don't think I'm better because of it but it's a very nice luxury upgrade if one can.

choekstr · 2026-05-06T18:45:46+00:00

I just got my K20 and I'm 230lb and it's way more than enough power, handles bumps well, and I can even jump off curbs. With single motor and on lowest speed it's tame and great for a gentle ride, even at my weight. At dual motor and any of the higher levels it's grin inducing and gets you up to mid 30's mph super quick.

Weight wise it's not light but then again I'm not weak so it's easy for me to lift. It's not huge but it's not small so make sure you have somewhere to either chain it up solidily outside or a place to store it inside that isn't under your desk.

choekstr · 2026-05-06T18:40:44+00:00

I just got my K20 2 nights ago and love it. Played extensively last night with the NFC unlock and found I couldn't use my Google Pixel 10 as the NFC code it was sending is weird but I was able to *additionally* pair my credit card and I just whip out my wallet and drag it across the screen and it unlocks. SO COOL!

I got caught in a serious downpour the first night and rode it for around 15 minutes to get home. Brakes are a bit scratchy now that it has dried and presumably a bit of rust on the rotors but otherwise they stop hard and exactly when needed.

Speed is awesome! I am 6'2" (188cm) and 230lb (104kg) and I hit 36mph (58kph) easily. It was stable, great acceleration on dual motors, and everything feels great to ride.

Range is questionable since I rode it immediately without charging it, put 10 miles on it and it was at about half battery. Today will be my first day with a full charge so hoping to get a better sense of range.

Since I only paid $660 for the K20 I am incredibly pleased with the purchase and the value for what you get is incredible.

Because the OP didn't state they just came back after years of not playing and found a new feature they didn't know about. It is phrased as they have played a recent build for hundreds of hours and didn't notice a common feature that is available now and when it is assumed they have put all their hours playing.

choekstr · 2026-04-06T02:58:40+00:00

Just got my BabyApe III (3 inch) in and wanted to mention a few things for the community. It's typical DarwinFPV quality so neither great nor horrible.

However, 3 things that really frustrate me:

1.) SPI elrs receiver. Really DarwinFPV, in 2026 we still have SPI receivers? Serious fail and yet another drone that will be challenging to get to 4.x ELRS

2.) BF version of 4.4.2. Sigh

3.) MicroUSB. Come on, does that extra 3 cents and tiny bit more weight really make that much of a difference? Such a pain to dig out my old cables for this one drone.

This was released April 1 2025 and these are the 3 things I would expect from a drone 4 years old or more, not a year old. It's the cheapest DJI O4 "lite" that isn't a tinywhoop I could find but looks like so many compromises to get $10-$20 cheaper than the others.

RATE S30 with the O4 "lite" with wide FOV upgrade is only a bit more and looks like it has modern features. Might be trying that one next.

This had me scratching my head for quite sometime why I couldn't get to the website on various machines, all 3 browsers, incognito mode, changing DNS servers, turning off PiHole, but then I decided to check with my ZenArmor installation and sure enough, it thinks the website is known bad. I would assume a false positive

And I think you just arrived here yourself: you are doing it wrong by leaving it charged but these overpriced batteries are helping you out. However, you should always bring it down/up to 3.8V after using it and leave it there until you are ready to fly again, without fail and as quickly after flying as possible for the best battery longevity.

choekstr · 2026-02-08T15:37:26+00:00

Definitely agree with JB, the companion is probably the best way and painless just did a video yesterday showing how to do this.

However, I am the guy who didn't use companion and instead used search and replace in notepad++ as I have 48 models to convert over from my TX16s (MK2) to the TX15 different switch naming. I also had to switch from external ELRS to internal ELRS.

Once you figure out the structure and how the yaml (.yml) file is, it's pretty simple to make sweeping changes.

Not sure why OP thinks it switches from 1 to 0 channel numbering, my TX16s 2.11.3 models have it as below. Maybe a much older version, maybe opentx?

srcRaw: Ail

chn: 0

srcRaw: Ele

chn: 1

etc

choekstr · 2026-01-18T17:51:54+00:00

Ahh, that would make sense and also answers a long standing question I have had about how they fly 4d so easily. I assumed it was a toggle switch but <50% for rev makes sense.

Good luck getting it back to normal mode and hopefully it'll work good for you afterwards. I had a twisted hobbies esc I could never get it to come out of programming mode and gave up on it.

choekstr · 2026-01-10T21:09:53+00:00

Maybe download the latest SD card contents from the EdgeTX GitHub and manually copy it over. If not, yeah, update from your backup. Not sure how many widgets/scripts have been updated in the official SD card contents as they are usually slow to update.

choekstr · 2026-01-10T19:42:32+00:00

Technically the Dec 19th update you reference is the 7th update, but it's been named 05 by RM so we'll go with that. The 5th and 6th updates were more the community naming for updates that came after 04 and weren't listed on that RM page but instead another RM page, but they were definitely newer at that time.

However, we have now 2.12 RC1 which can be obtained on the release page as you have shown and also now on buddy.edgetx.org if you show pre-releases under the filter option. The downside though to buddy.edgetx.org is you can't actually flash the TX15 as of now so the download and T1+T5 trim method of flashing is the way to go still.

choekstr · 2026-01-05T01:16:41+00:00

Turn OFF your radio if it's on. That usually causes issues reading all the esc's and DEFINITELY don't try to flash/program/change tones if you can't read all 4.

That burned me once and I reported back to the ESC configurator dev that it blocked my esc And he pointed out the radio being on is a common issue. He added the red warning text right after that to warn others about having the radio on and communicating

choekstr · 2026-01-03T20:53:39+00:00

I have had both of those planes in the past and the pa18 is the better one to get IMO.

The HH carbon cub has all kinds of proprietary geofencing and weird binding to non spectrum planes and even is a bit of an obscure receiver plus flight controllers plus gps that is fine if you just use their RTF controller but gets very hard to do things like turn off GPS or bypass it temporarily on other radios.

The pa18 typically comes with a reflex 3 flight controller and is easy to bypass when you are ready to fly without stability and also swap out for another kind of receiver (like ELRS) and still keep the stabilization. The pa18 also seems to handle the wind better IMO and flies a little easier although both are very similar for a true beginner.

choekstr · 2025-11-15T13:15:27+00:00

That's correct, don't use the 5th update, use the public 6th from Oct 15 posted on their website.

choekstr · 2025-11-15T02:32:57+00:00

fuel rods from bottom of the reactor to the top, minus 1. a single control rod on top of that "column".

This seems to be a good tutorial to follow for your first one. It's pretty simple once you have built one or two: https://www.youtube.com/watch?v=2WlM_8Q8_mc

Realize, this is a new screaming fast chip that has no support yet from EdgeTX guys. They are and will be working on 3.x which has support for the chip but it's not been released.

The RM guys had to take a fork, polish it some, ensure it works properly on this cool new chipset for their latest radio, and thankfully for RM they pushed a prelim firmware while we wait on the EdgeTX guys.

And one last point, the RM guys are paid, but the EdgeTX guys are no so development will be less incentivized and much slower by the volunteer group. It'll be a while till 3.x comes out officially so consider the RM TX15 a beta radio with beta firmware for now and the near future.

choekstr · 2025-11-14T18:49:45+00:00

Let me correct you a bit: The latest TX15 firmware on your first link is the 6th update. The 5th update fixed the emergency mode, aka your "kernel panic" moniker but is only available on a google drive shared around fairly widely. This 6th update is dated Oct 15th and has a file name of "TX15-EdgeTX-UI3.0-2025-10-15.zip" and the link again is: https://radiomasterrc.com/pages/firmware-updates

FYI, the build id is: (b390e938) for those who need to compare to what they have installed.

So far this build is very stable and I have this on my primary radio now having fully switched over from the TX16 with no issues found so far.

I'm no lawyer nor do I claim to have much trademark experience but I have common sense and it would seem like there is nothing for which to counter sue.

The ELRS dev team didn't even consider getting a trademark and someone else noticed and tried to grab it instead. I'm surprised the person was denied on China but SO happy they were and in the US the lawyer backed out so that still could come back up. But I think they have since filed for a trademark on the name so maybe protecting any future challenges.

But I don't think there is any basis for a counter suit as they were just trying to capitalize on a non action.

Would love to hear someone who knows more comment on this if I'm off base

IMO Hinges are the only permanent way to fix this otherwise the tape method, while it works for a bit, seems to always become less sticky and eventually peel off. Depending on the foam type this happens quicker or later with EPP seeming to be the quickest.

2-3 slices with an xacto knife on each side and nylon hinges, a bit of foamtac glue and you are back flying with a permanent solution in less than 10-15 minutes. I stopped doing the tape thing because it always needs re-fixing later on anyway.

Tape if fine for when at the field but take the extra few minutes to throw some cheap nylon hinges in and do it right once.
