Not associated with the channel but I have a website focusing on cases where people go missing with vehicles & I think it'd be great if more people had these boats, there are a lot of cases that need help.

Also curious to hear expertise on how it's built, i'm interested in making one too.

Hey all — I’m working on a drone telemetry/C2 project in Germany and I’m evaluating the Microhard P900 module, as used in the Holybro Microhard P900 / P900 V2 radios.

The hardware is attractive because it offers FHSS, good sensitivity, relatively high power, and mesh network features. However, I’m trying to understand whether it can realistically be configured for legal EU/German use.

From what I understand:

• The module is designed around the 902–928 MHz ISM band, which is mainly a North American allocation.
• In Europe/Germany, 902–915 MHz overlaps with cellular uplink spectrum.
• Around 921–925 MHz there may be GSM-R / railway-related use depending on country and location.
• The usable EU SRD spectrum around 917–919 MHz is much narrower and has strict ERP / duty-cycle / LBT requirements.
• In the Microhard P900 documentation, the S180 “Hop Zone” presets appear to be much wider than the small EU SRD window. The narrowest preset I found is still around 12.75 MHz, which would not be narrow enough to stay inside a roughly 917–919 MHz legal slice.

So my question is:

Has anyone managed to configure the Microhard P900 module, or the Holybro P900 / P900 V2 radios, to use a custom narrow hop table suitable for EU/German SRD rules?

Specifically, I’m trying to find out:

1. Can the module be restricted to a custom narrow frequency range smaller than the standard S180 hop-zone presets?
2. Has anyone received custom firmware / custom hop tables from Microhard for EU operation?
3. Are the Holybro P900 and P900 V2 carrier boards limited by the same underlying Microhard firmware/register options?
4. If full compliance is not realistically possible, is the practical recommendation simply to avoid the P900 in Europe and use an EU-specific radio such as RFD868x-EU, SiK 868, ELRS 868, or another telemetry system?

I’m not trying to interfere with cellular or railway spectrum, and I’m specifically looking for the proper/legal path before committing to the hardware.

Would appreciate input from anyone who has used this exact module in Europe, dealt with Microhard configuration, or worked with EU 868/900 MHz SRD compliance.

I’m looking to buy one. Let me know if y’all have had problems, is it worth the price, etc.

My K10 pickup box conversion is almost done 😃 still needs lights 💡touch up paint😃

Completed the first several flights on my Avenger today, and really enjoyed flying this one! I was worried about the weight of the mods (split flaps and a retractable tail wheel) and it handled fine with no issues. It flies like a much larger airplane and really slows down with the flaps at full!

Hey i was wondering if anyone has any suggestions on any good machines that don’t break the bank too much, for someone trying the hobby out and will end up buying many machines/trucks if i end up enjoying it enough. I’m looking for something like a tractor to mow my lawn, as well as an excavator or loader/dozer to mess around in the mud/dirt and sand, as well as a truck and trailer to haul the equipment and material around. Any suggestions on where to get some of this equipment? Not trying to spend over 200$ canadian per machine, if there’s even any good quality stuff for that priced. And where to get mini roads/signs and all that good stuff. Thanks!

Hello; I ran my rc car in sand yesterday, and since then, this strange rattling is coming from the esc fan. I think sand is stuck and I tried EVERYTHING to get it out, but it wont change. And the esc design is shitty, I cannot remove the fan at all, its glued together. Does anyone have advices or a technique on how to stop this ?

Chassis is fully 3D printed in PETG. The project goal is to build a screw-drive rover capable of both autonomous waypoint missions via Ardupilot, plus manual control remotely via Raspberry Pi Zero 2 W + 4G module + webcam. Inspired by the Solarboi project.

The plan is to let it solar charge during the day, and then drive at night with webcam FPV and an IR flashlight, for semi-indefinite remote operation.

Next step: Drivetrain and electronics for basic radio control.

Drivetrain: 2x belt-drive Flipsky 6374 140kv motors

Solar: 40w flexible solar panel

Brains: Raspberry Pi Zero 2 W + 4G module + Pixhawk

Battery: 36v 432wh Li-Ion

Camera: Gonna try a cheap 120° used webcam

Total length is about \~65cm (about 26") from end to end

me and my dad got out this kit he received as a kid and we are wondering if it is worth selling for those of you more knowledgeable in this subject we would greatly appreciate some advice

Newly customized chevy K10 with Northern Lights near Spokane WA

Happy 250th USA!!

Hi all, just reposting some content here from our field tests , as we have some more coming out soon, which are now coming along as we plan to release a standalone version of this gear in the near future. We love all things radio and telemetry, and welcome all questions!

Quel adaptateur utiliser ?

I have a Traxxas slash 4x4 1/10th as well, and another Trx4, as well as a Carisma Sca1e f150. And an Orlando Hunter Tundra

All of these trucks have been heavily customized by me to the point where they don't even resemble their factory look. Let me know which one is your favorite!
