Been trying to find a good propulsion powered plane and I found this one
https://createmod.com/schematics/b-2-spirit-bomber-v2 , https://www.youtube.com/watch?v=9ikyawDrM-c . It looks good but the issue is once I try to use the thrusters at the max setting only 3 get the energy and its not enough to lift it, can anyone help fix this?
