for maxium outside 3d 50%throttle hovers The first option will be the High Power Motor Setup. E-Flite recommends using the included 6.6:1 gearbox and 10T pinion gear, along with the included 12 x 6 propeller"(i use the 11x8 with this setup)". You just need to purchase the E-flite Park 370 Brushless Motor, 4100 Kv (EFLM1000) and the 3-cell 1200 – 1320 mAh Li-Po battery and you will not be disappointed. This is the most powerful setup option for the Yak54F and will give you the most power between the three options.
that hacker motor has too much load on your esc and batt the above combo
is what i use on the tribute and yak 54f flys for 15 to 20 minutes on 1320 and hovers at 50% throttle thats all i wanted in life and the 4100kv w/loud 6.6.1 gearbox &20amp esc made it happen
