Sky RC GSM020 GNSS Performance Analyzer Speed Meter for RC Car Helicopter Drone

This is an awesome tool!! I race radio control model boats and use this product for speed testing. Follow the instructions and it works perfectly. My friend and I both have the same GPS system. We've done some testing with this GPS course is a different system altogether and it is very accurate. The single most important thing is that you have it in a waterproof radio box and I also put it in small ziplock baggie to keep it absolutely dry. If you don't you'll have instant junk!! Just ask me!! :-) :-) Been there done that!!!

Works really nice I just don’t like that sometimes when I turn on my Bluetooth that will come on and kill my battery. I think it’s still a little expensive but it does what it says

Very nice tool to have. Speedo and drag use is very nice!
