I just read through your entire thread and noticed a few things. First, what a great fleet and a lot accomplished!
You asked me way back when what kind of run time I get out of a 8400.
Now that I have motor speed correct and some time at the controls, I get a solid hour and a half run time. I've got 2 of them. A .gens ace and a traxxas. The gens fits nicely, the traxxas is a little bigger and a snug fit.
I'm glad I did read through, I don't know where the heck I was but I had missed a lot of great info from you and Joe about radio settings for the 4200!
Thanks again for sharing and can't wait to see what's next.
