FAN:
Complete ducting is designed to fit our new 3W-1200 SpiderFan. At 6s Lipoly this Fan produces about 17N static thrust at only 32 Amps! This is enough for good sport /aerobatics performance and even enough to make a take-off from short grass without the use of a bungee: just "skating" on the 2 wheelcover fairings at full throttle! If you use a 7s battery, performance will be optimal for giant loopings and high speeds. Current at 7s is still very low at about 37 Amps: this gives you plenty of flight time(6-7 minutes) for a good aerobatic flight with about 21N of thrust! If throttle is used this Fan can also run on 8s but than current is over 43 Amps and flight times are shorter. 7s is most optimal for a high performance JePe A-4 Jet, 8s is for the speedfreaks who care less about aerobatics nor about lifetime of their Lipoly battery. Every battery salesman will tell you their battery can handle 50 or 65 Amps easy but in practise all cells that reach discharge temperatures above 45-50 degree Celsius have a reduced life time. This means that EDF models which run much of there flight time at full throttle should have a motor current of about maximal 40 Amps for cool running at a nice summer day.
