Does anyone knows what is the max supported voltage for a Taranis X9D first version? I bought it back in 2014.

Appreciate it.

Hey out there, I have a stupid problem. Sometimes my Spektrum transmitter is not connecting to my receiver. There is just no reaction - the servos are not moving at all, the ESC is not beeping … nothing.

A few hours or days later everything is back to normal

It happens with both my Spektrum (DX7S and DX8) transmitters, and different receiver, in at least 2 different foam only models

Any idea?

I really wish I could own a Goosky E2, this helicopter is so beautiful. The sound when flying is also very crisp, just like a real helicopter.

I do very little flying so I don't want to shell out for a fancy transmitter that I won't know enough to properly use the features of. What is a low cost option that will get the job done?

Does anyone know of an LED Dimmer module that also has a memory function so if power is switched off to it, it can restore the same level of brightness upon power restoration?

Hi RC folks - I'm a climate scientist working on thinning ice in polar regions. I have developed an instrument that measures the thickness of floating lake ice and sea ice using radar waves. The instrument weighs around 5kg and is mounted on two skis set about 60 cm (2 ft) apart.

I am looking to pull it with an RC car so that the operator doesn't have to travel on the ice, which might be too thin to support them. Does anybody have any advice or car recommendations for this? The wheels would have to be specially adapted to snow (spiked tyres), but I'm really looking for car recommendations. Ideally the range would be up to 500m (we can have a fairly big, fixed aerial) and the battery life would be perhaps 20 mins?

Can anybody recommend a car/manufacturer for this?

Has anyone had any luck binding a the new Losi Micro-B SPMXSE2825RX 2 in 1 to a RadioMaster MT12 transmitter 4in1. Any help would be great. I thought I read somewhere that it is possible but I’m not having any luck tracking that back down. Thank you for any help or guidance you can give.

Is it a crappy battery or am I just an idiot?

What is everyone running now? I've always used spektrum but after an incident the other day involving my brand new edf jet, I'm moving over to something else. My plan is to use ELRS but I don't have the external module yet.

I posted a similar question earlier but my original account was hacked and deleted so please excuse my repost.

the reason why I can't just use servos and control horns is because of the tiny budget that's shared between the working model, the 2x size display model with a visible interior, and booth decoration. we also only have a few weeks to make everything so I can't order stuff online, the only place where I could cut corners was the working model since I'm part of the team that's working on it, I have seen people repurpose drone hardware to make steering this way possible but since we're making it from the ground up I was wondering how we'll need to implement this? the only part that we have so far is the radio transmitter and receiver which we're borrowing from someone since I don't know everything that'll be needed for this.

The controller in question

Hey everyone, I'm hoping I'm asking this question at the right place. I'm looking at one of those cheap 1:43 drift cars (the jiabaile ones) and though I'm not too interested in the RC hobby yet, I want to tinker a bit with the device and tie it in with a linux running sbc. I want to give usb controls without compromising the original function of the device, so I don't want to open the cars itself. I'm kind of aware that these transmittesr use propietary protocols (correct me if I'm wrong please) so I can't just use another controller.

I've seen people using digital potentiometers controlled from an arduino. I'm thinking of something like this, but potentially less invasive, and with a button to switch controls from the rc to the microcontroller, which has a usb port or bluetooth connection or whatever.

What do you think of this approach? Has anyone here tinkered with the controller like this?

TIA!

Edit: it's 2.4GHz if it makes a difference. Kind of stops me from designing my own tx device I guess.

I; have a 4000mah s3 12 Volt lipo battery. can I use it to power a 14.8 volt ELECT ENGINE without causing damage.

I paid the $100 through Steam to get RealFlight, and I'm not super impressed with it. I hooked my TX16s up to it through a USB, and everything works fine, I just think that the simulator feel very dated.

I used to fly on PhoenixRC back in the day, and I don't feel like RealFlight is that much better, despite there being a 10-year gap between when I last used PhoenixRC. In the (almost) year 2025, for a $100 download, I was expecting something that looked, felt, and had models that were more modern.

My main problems are that the the graphics don't look very good, the panoramic flight environments create weird depth perception issues that make it hard to see the model, and the available models are dated (surprisingly few helis don't have flybars despite flybars becoming obsolete in RC helis about 10-15 years ago).

Overall, it just doesn't feel like anything close to what a modern simulator should be like. Compare RealFlight to any $100 video game that's released today, and it just falls really short in all of the metrics I listed above. If you're in the market for a flight simulator, please look into other companies before going with RealFlight.

I'm building a remote control model airplane from scratch using a laser cutter. It will have an 800mm wingspan. I was originally planning on using 1/8" balsa for everything, but now I'm realizing that balsa likely won't be strong enough for structural components, and was considering making those out of basswood. With that being said, what parts experience the greatest load as a model airplane flies/what should I use basswood for instead of balsa?

Thanks.

What specs should I look for? Id like to find one locally available on prime ASAP. Transmitter says x55 gfsk

I'm trying to get into RC and looking to buy an ELRS Radiomaster Pocket. I live in Sweden and it seems like all webstores that are deliver here have at least 30% higher prices. Are there any stores or places which sell reasonably priced RC items?
