I would have loved to do the trade in with a Losi RTR radio but their fine print stated that RTR radios would not be accepted. I have two 3PKS and really wanted to buy the 4PKS but I'm not parting with those to get $150 in credit, I'll just wait for a rebate or really good deal to come around.
I was ready to pull the trigger but bought a car,ESC, and some batteries.
