to make it simple ground control is great and the formula 1s are good since you just have to replace the block in the middle and you have a new frame or if you want freestyle you can buy that h block and vwala! or the new create originals frames they have a awsum! h block groove and they slide very well,you can also customise your fram with your own personal graphics on both sides. worth every $$$.
