I went back to the off-road RC track today with my son who's 10 and was a new born when I was doing this before. Stopped in 2015 after a bit of a catastrophic accident there and lost interest.
Daughter was originally going so there are two controllers in the pic but we left one at home. I had two Tekno buggies and down to 4 of my 6 batteries.
Everything still worked well and we finished everything race. Good to use them old stuff again and I have plenty of tyres and spares.
