I also adjusted the screw on the tranny to stay in 1st gear, truck flies even on just 1 gear. I had it at the track yesterday and it did about 10 cartwheels at about 30mph at the end of the straight away, flipped over a two foot wood wall and landed on all 4, unscaved. I've read some posts that redcat or himoto cars are cheep and break a lot and I was very carefull with the truck when I first got it. After about two months I've only spent about $6 on broken parts and jump and flip it all the time. These things last. Any Tsunami owners out there also have hurricanes or Torpedas, can they also take the beating?
