Making RC Lawn Mower

I used a 173cc gas engine, this engine has a battery charging function, the charging is too weak to cope with the current consumption, but it significantly extends the working time. The mower is powered by two 200w 350rpm motors, the electric motors are powered by two rc brushed motor speed controller. I used an electric lift with a maximum lifting capacity of 200 kg to adjust the height, I powered the rc brush motor speed regulator, it is less powerful than the ones I powered the motors with. The gas engine is turned off by a two-channel rc relay that I connected to the coil, After the remote control is turned off or the range is lost, the relay closes the contacts, which causes the engine to stop working. I adjusted all dimensions to the size of the mower housing and wheels mini quad. Working with a remote-controlled gas mower is a pleasure and great fun, the range of the remote control is large, so your legs will thank you for such work :) Control parts I used: Controller RC Electric engine -https://amzn.to/4aME1oi Controller RC electric lift - https://amzn.to/44ebZ2x Remote Transmitter - https://amzn.to/3Wb9EU4 Gear Reduction Brushed Electric Motor - https://amzn.to/4bafXLR Electric Linear Actuator DC 12V - https://amzn.to/3xI0Fj6
