Here is a video of me testing the plane with different configurations. i also built a little rocket with wheels using a separator engine (not in the video) just to see if it was a part like the cockpit or something that is doing the same thing.

hmm just tried again made sure to lock my steering. removed anything not required to fly. also rebuilt the plane just in case i rotated something strange. with locked steering i am able to go a little faster before blowing up. however the forces are still there. i also checked F12 everything looks normal. something else that i noticed now that i have been able to go a little faster. i can't get it to take off. everything shows that it should fly no problem. and i can reach speeds that should let me take off but it will not take off. as a side note i rebuilt the same plane in vanilla + the few mods that are used in the plane. it flys just fine. no weird forces. takes off beautifully. i think i am going to remove all mods and install them one by one and see when the bug comes back(if ever). ill let you know of the results.

Hello, I am running into a bug and was curious if anyone else was having this issue. i recently reinstalled RO via ckan and am trying to build my first plane. the plane checks out with FAR's stability check. but when i go to take off once i reach about 20 kph the plane is impossible to steer and in fact acts like there is a very strong cross wind that changes directions every couple of feet causing the plane to roll and crash. i even took it off the runway thinking maybe the non upgraded runway was just too rough. but same thing happens. really interestingly in i go off the runway and get the speed up to about 15 kph the plan will make a wide circle on the ground. sometimes clockwise others counterclock wise. i tried reinstalling KSP and RO. and i copied Scott Manley's plane design that he shows in one of his recent videos...but it didnt help at all. the same thing is happening. i also noticed that my sounding rocket seemed to be affected by these weird forces also though not as bad. after launch the rocket would pitch random directions as it was falling through the atmosphere(didnt notice as much while going up). Any clue as to what could be causing it?
