I have to agree with Konrad (at least this one time
I have had great luck with Castle's products. I use their ESC's (Thunderbird) almost exclusively. I do have one or two others, but any new ones are Thunderbirds. I have the PC attachment so that I can "Program" the ESC without having to hook up a receiver.
Also, when I first started back into the hobby a few years ago, I electrified a few of my Freeflights so I could fly them out of a local ball field. I didn't want to buy a new radio, and all I had was an old Futaba Skysport radio. I got a few of Castle's Berg receivers, and they have worked a charm since. Light, reliable and pretty inexpensive. (Not cheap!)
I did have a few minutes panic, though... I need a couple Thunderbird 18amp ESC's and they are out of stock everywhere. I went into my local shop and they guy said something like "I think that Castle is having some problems..." Well, no, it's just that the 18 amp was on back order. Supposed to be in mid-April.
How could any one not agree with me?
I’ve been with CC since the beginning with their brushed motor ESC like the Sprite 25 and Pegasus 55. I also had the Dragon sensored brushless ESC. It was smaller than the Aveox ESC.
So in the intervening 20 or so years you might imagine I’ve had a few customer induced customer support issues. Dave Castle of CC has been customer focused since the very beginning. I remember burning up one of his ESC at a contest (BEC failure). He gave me a replacement and said be careful and look for a burned up, damaged servo amp. The true cause of the BEC failure.
Wow, the Berg. Now that is an obsolete product but was/is a great one . I still use a few as I’m too lazy to dig them out of my planes. They were/are the best non-Dual Conversion (DC) 72 MHz (DSP) Rx period. And their later DC 72 MHz Rxs are some of the best. CC took over the Berg line at a time when the Berg Rx was suffering “sleeping sickness”. CC put in a lot of time and effort to over come this and at the same time never accused the end user of being the source of the issue.
Love the Castle link! The ease in which one can up date the firmware is worth the price of the CC product.
Note: CC products are not throw away products, for that we have a lot of choice in the many products sold by HK and the like. Again Quality pays it does not cost!
All the best,
