Retail orders above $80 may be eligible for free shipping, including contiguous United States, Alaska, Guam, Hawaii, Puerto Rico, and APO addresses. We will use either USPS or UPS that most packages can be delivered in 3-5 working days, but not guaranteed. However, for packages contain large and heavy items, such as power supply, we may use parcel post service or UPS Surepost that may take up to 7 working days to be delivered.

If you have not received a tracking information E-mail, please log into your account and click the "view order" link, then click "Track your order" link to find out the tracking number and ship method.

USPS Priority Mail is typically delivered in 3 working days. But very occasionally a priority mail package may be delayed for several days in the mailing system. If delivery time is extremely critical to your order, we would recommend Priority Mail Express or other couriers.

Domestic First Class Mail is only 1-2 days slower than Priority Mail in delivery. We suggest domestic customers choose First Class Mail for an order under 15 oz to save shipping cost.

Real shipping cost is calculated according to package weight and distance, and can be found in the checkout page after delivery address is specified in the fields.

BuddyRC is always a pleasure to do business with!

Very nice radio. I'm coming from years of Spektrum DX6i and DX6 and the 10 additional channels are awesome for like $100 less! It's taking me some time to get used to the new user interface, but it seems very capable. I've just not been able to spend much time with it. I did get two of my quads setup and bound to it and have no complaints at all :) It's about 1/2" narrower than the DX6/DX6i, meaning the sticks are about 1/2" closer to each other in the X direction if that matters to anyone.

Fantastic receiver for flying at the park

I have put a few flights on these and really like them, Granted I fly usually no more than 350 meters away as my flying area is fairly small but these little receivers work great and as far as I do fly the RSSI is still reading in the high 70s to lower 80s so impressed I bought 3 more of these and a couple of the R161s to try out. Id bet in a lower interference environment these will pull off the 1K + advertised range. As for Pricing, Availability, and Shipping speed Buddy RC took it out of the ballpark.
