I just got a M05, finally!
I did the build last night, and I really like it! An upgrade over the M03 for sure!
Also bought enough parts to build another M03, which will be mine. The M03 chassis pictured above will be setup for my daughter to play with. She is 6 now, so we will see how she does with RC.
M05 next to the newer MF-01x 4wd M chassis, which is awesome in its own right!
