Yes, absolutely. Hoverfly products are made to be as compatible as possible with as many different brands of radios as possible.
However, be aware that you may need make adjustments depending on what type of radio you purchase. The specific adjustments to be made will vary depending on the brand you purchase, and are well beyond the scope of our FAQ.
We recommend Spektrum radios because, in addition to being a great product, this is the brand that we most often use in our in-house builds. Therefore, we are usually better able to troubleshoot problems that may arise with your radio because we have these products on-hand at our facility.
