I currently have and operate two of these receivers, they work great. I build stick and tissue model airplanes with roughly 24 inch wingspans, just right for park flying. I have had no issues with these receivers so I bought two more from FPV. The receivers were packed and shipped quickly and safely and are now ready to install in my next project. Note: If you are not proficient at soldering then I would not recommend these, but if you are, these are great.
