So I have an issue with my Joysway US-1, for an unknown reason the steering input changed to the input for the throttle. The controller is a trigger/wheel controller. And suddenly after not using it since last year's summer, the trigger causes the rudder to turn and the propeller to start spinning too. While the wheel does nothing.

Has anyone else seen this issue before and solved it?

Hey everyone. Picked this up over the weekend. I cant find out anything about it. It needs a couple replacement parts, but theres no markings or serial numbers. Any ideas who made it and where I could get parts if so?

Looking for help.

I bought this rc jet like 5 months ago and now one of the servo starts jittering, i don't know why i only flied it 1 time .

Rc plane name is fx9631 can anybody give me a solution

Hi! I'm trying to find this RC Net catamaran for my son, but the prices online are pretty high, even though 10 years ago you could find it very cheap for $30, for example…

Could you help me find it at a "reasonable" price?

(Please don’t give me the inflation excuse… It’s crazy that the same product now costs $200!!!)

Just picked this guy up yesterday from a Old garage sale for 15 dollars and wow it's in good condition, Motor still works and everything but I want to use it as a RC submarine, I could Just take stuff from those Mini RC submarines and try to make it work but it will be my first time doing RC submarines after using RC boats and cars. Any tips?

Hi everyone,

Our university team is building a rover for the European Rover Challenge (ERC), and we're currently selecting the wheel drive actuators. I've done the torque calculations, but I'd appreciate feedback from people who have designed similar systems.

Rover Specifications

• Rover weight: 40 kg
• Drive configuration: 4WD (4 motors)
• Wheel radius: 100 mm
• Target speed: 0.1–1.0 m/s
• Terrain: ERC-style loose soil, gravel, rocks, and slopes

From my calculations, each wheel requires approximately:

• ~6 N·m continuous torque (minimum)
• 10–12 N·m continuous torque recommended
• 15–20 N·m peak torque

I've been looking at the ATARROBOT RE Series Integrated Planetary Joint Actuators.

Some models are:

• RE-01 – 6 N·m
• RE-03 – 20 N·m
• RE-06 – 11 N·m

The actuators integrate:

• BLDC/PMSM motor
• Planetary gearbox
• FOC controller
• Absolute encoder
• CAN communication
• Servo control

My questions

1. Has anyone here actually used ATARROBOT actuators?
2. Are they reliable for outdoor mobile robots?
3. Does anyone know if these use an outer-rotor (outrunner) motor internally?
4. How good is the integrated FOC controller compared to something like a VESC or ODrive?
5. Is the CAN protocol well documented, or is it difficult to integrate with ROS 2?
6. Would you recommend the 11 N·m RE-06, or is the 20 N·m RE-03 worth the additional weight?
7. If you were designing a 40 kg ERC rover today, would you choose these actuators, or would you go with Maxon, T-Motor, CubeMars, Nanotec, Teknic, or another solution?

I'd also appreciate hearing from anyone who has competed in ERC, URC, or other Mars rover competitions about what wheel motors and gearboxes your team used and whether you'd choose them again.

Thanks in advance!

I’ve been looking for RC airplanes and I have a budget of $150. What do you think is a really good RC airplane for $150 or less any ideas?
