Sanwa transmitter and futaba receiver will this work?

[daz75]

Sorry for the daft question but it's probably 15 years since I did this. I've got my old losi xx all wired up with a futaba 40mhz receiver in it. I always used a sanwa exces which I've found and charged up. First time I switched everything on the car went mad, thought it might be crystal related so found some new sanwa crystals and now the cars steering works but power is constantly on, trimmed it right back with no joy

Do I need to be using a sanwa receiver or is something else wrong?
