I have just received a new GP.07 and the instructions call for 15%-20% nitro and I fly all my engines on 10%. Question is, will it run ok with 10%, or do I need to step it up to 15%? I'm not looking for "all out performance", just a reliable engine run. Is there anyone out there that has tried a lower nitro fuel in their .07 engine and how did it do?
Thanks for any help you my have.
