Hey, been running hyper 7 on 20% and needed to get some more. So i let my dad get some more from the hobby shop and that man gives him 16% saying your gettin 20% more heat and 2% lmore speed with 20 rather than 16. Is he right? I am personaly really anoyed because i said to my dad DONT let him give you 25 and DONT let him give you 16. Its so stressfull. Is this hobby man right?
