    My son testing the Vtechtuned Spark on the CC track

    So far he is doing really well on it. Takes allot of adjusting coming off the XP from last year.
    We need to start working on handling now. When turning too hard in race conditions, the ski will either roll over, or it completely comes unhooked and slides sideways for a long distance.

    Nice, Are the stock sponsons adjustable to some degree?

    Not really. Looks like they left enough room to drill out holes above the existing holes if you want.

    Did you let off midway? Looks like he pulled a good chunk all of a sudden...

    No. Once it hooked and got into the higher rpm it took off great. .The slower spark did lift before the other. ..right at the very end of the video
