Great programmer for out in the field changes for your esc.
Works great for making changes out in the field. You can actually confirm yoiu are making the right change while looking at your setting on the lcd display. Way better than using the set up button to get into your programming options on your esc.
Wow what a great product it does the job if its being able to modify the esc settings or even updating your esc firmware this thing does it all did i mention also can check battery voltage and cell count i would highly recommend this product for all your spektrum products
