Fly a 45-degree upline at 60 to 70 percent throttle and do a slow half roll without rudder. The right CG holds the 45-degree line with no heading drop.\u003c\/p\u003e\n\n\u003ch2\u003eRC System Requirements\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e6 channels, 5 servos \u0026amp; 1 ESC\u003c\/li\u003e\n\u003cli\u003eAileron servos ×2, 6 kg or more\u003c\/li\u003e\n\u003cli\u003eElevator servos ×2, 3 kg or more\u003c\/li\u003e\n\u003cli\u003eRudder servo ×1, 4 kg or more\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSuggested Setup\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConventional nose:\u003c\/strong\u003e \u003ca href=\"\/products\/precision-aero-products-pck-f3a-drive-with-4-blade-prop-hub\"\u003ePrecision Aero Products PCK F3A Drive\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContra nose:\u003c\/strong\u003e \u003ca href=\"\/products\/adverrun-avr-xs-v4-contra-drive-with-egodrift-4025ec-570kv-motor-1-pack\"\u003eAdverrun AVR XS V4 Contra Drive\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eServos:\u003c\/strong\u003e \u003ca href=\"\/products\/mks-hv747-high-torque-digital-servo-for-airplane-jets-electric-models\"\u003eMKS HV747\u003c\/a\u003e ×3 for the ailerons and rudder, \u003ca href=\"\/products\/mks-hv69-high-torque-digital-servo-for-airplane-jets\"\u003eMKS HV69\u003c\/a\u003e ×2 for the elevators\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery:\u003c\/strong\u003e 2 × \u003ca href=\"\/products\/precision-power-f3a-5s-30c-5250mah-lipo-battery\"\u003ePrecision Power F3A 5S 30C 5250mAh\u003c\/a\u003e for 10S\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eNot sure which nose or drive suits you?
