thats a good question as far as bang for buck im not sure i know where i am the MG a anywhere form 100-150 $ cheaper then other motor out there with the big names and yet the MG delivers and just keeps delivering ...

the new gx series are awsome to i really liked my gx5 heaps of power and run time but i forgot to charge my receiver pack or it failed , if theres a new go tech to try i will certainly always get one thats for sure
