    I emailed Horizon and this is the answer I got.

    Jim,

    Does it have a clear backing that you have neglected to remove? Maybe they switched from the paper backing to a clear material.

    The Taipan is an ARF, and most Ultra Sports are kit or scratch built, so I can see that...

    The OS 160 twin was one of the originally recommended engines for the Ultra Sport 1000 and I believe that a firewall position for it is shown on the plans. The problem is that the airplane looks odd...

    Thereby removing yourself from the "responsible person" category.

    You might also note that FAA is delegating responsibility for enforcement of it's UAV rules to your local police department.

    Restrictive rules are made to control the "idiots", but unfortunately, they cover the "responsible person" as well. You seem to be in denial, but I assure you, FPV flight beyond the pilots unaided...

    Success!

    RECAP:
    The Ultra Sport has been in constant production for 25 years and clearly its flight characteristics have a lot to do with that. The Ultra Sport is groovy, flies on rails, feels locked-in,...
