I want to give my HSP crawler to my brothers grand kids, but it has issues. At first I thought it was the RC transmitter so bought a new one, still no dice. The steering seems to work but no proper drive power. When I first got it out after 5 years in storage it seemed to get stuck in hyper drive, now it barely goes anywhere. Have spent $150 on new charger (I lost the old one) now beginning to wonder. Next try would be to replace the ESC I suppose but I'm right out of my depth. Can anyone help? Can you still get parts? It could even be something simple but I'm clueless now.
