Make sure you do the break in. Do not take it out of the box and just run it.

can you tell more about what you mean it needs to be run to break it in ????????

whatever dont bother

Nitro engines need to be ran in a certain procedure when there new so the piston and piston sleeve can develop a precise fit. I'm pretty sure when you buy the Hyper there will be directions on how to break it in.
Example: My t-maxx i had to run one tank idling, then, let it cool, then another tank running it at 1/4 throttle for 3 seconds untill the tank is done and so on.

No problem, just if you have anymore questions, just ask them here so you do not ruin your new rig. I know if i would have never joined here, I wouldnt have a t-maxx in running condition anymore..
