i got a tsunami and ive seen every one say they are 2 speed but i have never herd mine change gears and when i start it, it will run good for like 5 mins and then it starts to bog ive messed with trying to tune it better but i don't know if its that or not. also when i hold it up in the air and hit the gas it seems to take off relly fast and do nice but when i put it on the ground it will hardely spin the tiers in dirt.


Thanks, Dustin Swords
