Help needed: Running in Nitro engine

    Hi all,

    I just got a HPI Trophy 3.5. Brand new.
    So I got myself some nitro15%; read the manual.

    Following the instructions, the engine starts straight away. However how do I get the engine to 'calmly' without the wheels turn around too much?
    Once I start the car with the throttle 1/4 open the car nearly lifts of it's stand. I then push the throttle servo back a bit but this stalls the engine.
    Any help appreciated....

    Thanks a mill

    Bring it back to the shop where you bought it. They will re-tune it free I expect.

    If you bought it long distance, you have some study ahead of you!

    Hope this helps. :-)

    I used to follow the engine manufacturer's break-in method - until I discovered the heat cycle break-in method.

    Here is a very good tuning guide, written by a guy who mods engines.
