I bought this at an estate sale a couple of years ago. It was mated to a model ground tractor that seemed made as a support system for a radio controlled airplane setup.

It’s very nicely made, quite heavy, battery powered (batteries go in the hose tubes), nicely detailed.

I think the idea was to actually use it to fuel a model airplane. It has a working pump, fueling hose with nozzle, etc.

The tractor it was paired with was one that looked to have been modeled after those small, low tractors found on air fields. There were models of men in (or on) the tractor. Life size, this would be a smallish fuel tanker of about 12 feet in length (guessing).

Are these, were these, a thing? I was surprised at the quality and detail. Any ideas of what it is, who made it, what it’s worth? Is there a better sub for such things?

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.
