Hi,

I don't understand why you would run a rigger on 8 cells. I run riggers for competition and you have the choice between 7 cells ( H1 rigger ) or 12 cells ( H2 rigger ).

I can tell you - that's for 7 cell use - to aim for about 4000 , max 5000 kv motors. Ifnot , you have to use way too large or too small props with all disadvantages that come with them like propwalking and more bad stuff .

pick the one you like best or try them both. If you try the 5300 you have to keep an eye on the battery and ESC temperature because they will get very very hot.
