I have had nothing but speed passion in my tool box ever since brushless came out. Now have 4 esc and 4 motors a 2 Fantom 17.5. I have not had one problem with software or any problem with downloads. Have not tired any other products so I do not get confused with other stuff and try to apply that to Speed Passion. Have asked Charlie Barnes and Ritchie R. a few questions. They have been very helpfull.

Have had better drivers drive my cars and they are faster with the same car.

I feal if a person sticks with the same product and understand it there will be fewer problems.

Regonials this Sat will run 2.0 and a 21.5 speed passion.
