ya today i got it broken in and i ran about 4 tanks before i started giving it gas and on the sixth tank it could hit full throttle very easy. I live at a very high altitude (8,995 ft) so it stalls often. But my friend has a mgt and he said it took him about 10 tanks to be ajusted to the enviornment.
Iv got the RC10 and its great! My friend have that XXX-NT and it comes with a good radio but has less aftermarket parts... But they are hard to break! That RC10 has the most.
