@TMach5 thx also I fixed the engines just after so here's the new aircraft: https://www.simpleplanes.com/a/o1e6Rx/The-biplane-mark-2-fixed
@Skua no your doing nothing wrong it's just that I didn't build a good vtol for this, although I am working on the engine
@Skua I just built a XFV-12
This prototype is really good considering it doesn't break at fast speeds ( above sound barrier 760mph).
