Hi my friend, my F4 came out at 4.3 KG. I'm using all ABS and lots of adds on like center burners, jet sound module with 2 speakers and, Jet fly 80 mm, operational front LDG doors. I need your expert opinion please, will it fly, okay? Thank you.
Sorry for the late reply. The flight weight of my plane is 3kg (including 700g battery).I think it will fly with 4.3kg, but it is not a light flight weight, so you might want to check the power by taxiing, etc. ^ ^
PLA filaments tend to deform easily... It's also hot in Japan, so they tend to deform easily, so I'm currently printing an airplane with ASA filament ^ ^
Thank you 😊 By reducing the weight of the fuselage, processing the upgrade from 70mm to 80mm and setting the vectors, we can make this kind of flight ^^ We will continue to improve it 😉.
Looking good! Few questions: 1) Twin 70mm option? 2) Specs on battery? Im curious because freewing 90 doesnt accept some bigger battery (6000-6200). Maybe battery bay is enlarged for more room? 3) Seems there was alot of wing rock. Windy day and lighter plane? 4) Diameter size of the exhaust nozzle? Seems its the same nozzle from FW F-15.Reducer to lower nozzle to 59mm output helps the FW 90mm and wondering if would help on twin 70 or 80...
1) twin 70mm is an option yes 2) yes larger battery is possible.. mine has a 6s 7000mah battery, RC.Hiro used up to 2x 6s 4500mah 4) Nozzle is about 90% FSA for 80mm and 70mm EDF (2 Versions)

Thank you 😊 I am using OVERTURE AIR PLA but already the F-15 is deforming due to heat and has a habit of flying 😥3D Printed F-4E Phantom deformed due to heat and was retired 😥. Both fly very well so I will print again with filament that can withstand heat 😏.
