I'm having an issue with a trijet I built a while ago. It has a similar design to the Boeing 727. For some reason, it can't lift off during takeoff. This can become worse if flaps are extended. The engine used is the J15 (XML modded to increase power). It's takeoff speed is literally 500kmh+. Is there a way I can fix this?
Can you upload it unlisted and tag me? Maybe I can help but I'm not good
Either you have too much weight
You have a smol wing
You don't have enough lift
Wt happened?
