Ultimate Hobbies is a large hobby shop with a tremendous selection, lots of parts/accessories and electronics for the R/C modeling community at lower-than-average prices.
I was referred to Ultimate Hobbies by, of all people, an employee of another well-known hobby shop that didn't/couldn't carry the equipment I needed. Thanks to them for a great referral.
It was suggested to me that I specifically speak with Topper. Topper is an older gentleman that I found to be extremely knowledgeable and helpful when it came to R/C, aircraft in particular, at least as I experienced during my visit.
During the hour or so that I was there, the store received at least two phone calls where the caller specifically asked to speak to Topper. Other customers who walked into the store while I was there all came to speak directly to Topper as well. It was a "take a number" situation, so to speak . . . Topper was well worth the wait and devoted full attention to my concerns when it became my turn to be helped.
My overall experience with Ultimate Hobbies was quite pleasant.
Only drawback I can think of is that they have a strict return/service policy. If there is a problem with your radio, for example, a little sticker on the box informs you that you are to deal directly with the manufacturer. I was also informed by a third party that Ultimate Hobbies penalizes returns with a 25% re-stocking fee, regardless of reason or even if the seal on the merchandise has never been broken. Caveat emptor in this regard.
