Dear Sirs, I would like to have your opinion on an idea. Forgive me if is a stupid idea. We have an AXE & a BRUTUS all stock with brushed motor 550 12T and 4500 mAh 60c lipo. I have in stock two motors 540 17T. If I replace the stock 550 with the 540 17T using the same stock gears, should I have longer running time? How much longer? How much would be the performance decrease in percentage more or less compared to stock 550 12T? Thanks for help in advance.
