DIY Su-57 Felon with Ducted Fan or Pusher Prop : Which One is Better?

I made this Sukhoi because I already made an F-22 Raptor plans, because I think it would be interesting if I made its rival too which is Sukhoi Su-57 Felon or in Russia known as T-50 PAK FA. This model is not design specifically for neither EDF or pusher prop, I just design the model airfame that can be built with 5-6mm foam board or depron or polyfoam, without any propulsion mounting design. You have to figure out yourself, but you can see on the build video how I install a single 70mm EDF on center between the two exhaust. For this setup I use FMS 12 blades 6S 70mm EDF, with 2.6 kg thrust with 80A ESC and 6S 2200mAh Lipo, I think it’s more than enough than the weight itself. I also convert it from EDF to pusher prop using DXW 3536 1200kv brushless motor, 10 inch prop, 50A ESC and 3S 2200 mAh Lipo. Both perform well, while there’s some problem in the beginning, you can see it on the build video on Youtube. Download plans files : Join this channel to get access to perks: Specs : 1.
