    I bought these servos for my 6mmflyRC F-18 park flyer and they are awesome! They all work great and are an extremely good value. They keep me flying on a budget. (Posted on 5/27/2009)

    These are actually SG91R servos. They are the same as the ones from You-Know-Who, but are stocked and shipped to your door from right here in the Good Ol' US of A. Don't waste time trying to find a better deal. Just buy these and build your planes. (Posted on 3/21/2009)

    Review by Carl Noble
    Without a doubt, these are much better than HS-55. I bought 12 and have been using them since Dec 07 with out any problems. You can get 12 HS-55 for around $156 wheres 12 of these cost only $40. I saved over $116 on servos alone for the same or better quality. (Posted on 3/25/2008)
