I need a bit of 'major' help...

Hello SimplePlanes community.

I need some help. I'm making two aircraft (one propeller and one jet), but I'm having issues with them both which has only happened on these two aircraft so far. Both of them have the same type of issue. When I'm pitching, the jet will star violently rolling and I can't stop it unless I stop pulling back. The propeller aircraft will flip backwards and can also have the same rolling problem as the jet.

If someone could have a look at these two planes and see if they could fix them, that would fantastic. :3
(Note: you can put landing gear on the jet aircraft for testing purposes)

    I know this was yesterday, but after inspecting the crafts I concluded the following:
    .
    .
    For the prop plane, the problem was that the CoM was too close to the CoL, which could be easily solved by adding weight on the front.
    .
    .
    For the jet, I really don't know, but I noticed that it has very big elevators, which could be the problem.

    Your Pitch Control Surface Were Probably Too Big, Just Make Them Smaller

    The wing load of both aircraft is incredibly high, around 40lbs/ft2. You should be aiming for around 20lbs/ft2 generally. Try adding more wing area or decreasing the mass of your aircraft. Also changing your wings to flat bottom helps too.
