burito, I recently ordered one of these. Not sure if it was the first batch or not. It was from Superior which was the onsite hobby shop for Snowbirds. Does the speed control need to be updated regardless if it doesn't have the latest firmware or just if you are getting the stuttering? My concern is that since I don't know what causes the error (say its the receiver you use) it might work for me initially and then down the road begin to not work? Or is it just some kind of corruption that either exists or doesn't?
Thanks.
