I bought the Rc concept a few months ago and couldn't be happier  . Maybe it's the newer software because latest software update from SP is from 2014...
Price wise they are about the same but I will never go back to SP |
4 years is a long time in terms of development in electronics and software.
Did you try re-flashing it? You can put the correct hobbywing software on the old SP esc's, where the models are similar.
The RC concept ESC's are a much later generation, and do perform excellently.
