@HKAerodynamics I fixed It already, but thanks for the tips .P.

i hope this was useful... i probably just explained to you all life's problems... and the instructions on how aircraft work. put this method to good use, it works wonders and i'm very proud of it. well. see you later!

also, try to move the entire wing back as far as you can to the back of your aircraft and move the control surface allllll the way behind your plane. this will give both stability and mobility, which is a rare combonation in most conventional planes. i see that your rear stabilizer is far too forward on your fuselage. if you move it all the way to the back so does the COL and hence, more stability and the controll surfaces get more leverage.

and how big are the control surfaces? if they are more than 3 ticks, all they do is throw off your balance. its either 3 ticks on your control surfaces or you make the entire stabilizer pitch with a rotator, i use rotators on my most advanced aircraft and my most recent generation of aircraft.

wings may be too big. one of them must be getting thrown out of whack when you pitch. happens to me sometimes.

@Glaceon
move the CoM forward, away from the CoL.

@Glaceon that is my assumption based on the description of the problem. I'm mobile, so I can't download it.

@EternalDarkness Okay.

@Glaceon it happens to me often in the balancing stage of my buidls (the part where I make it fly). You need smaller pitch control surfaces or to move CoM and CoL further apart

@EternalDarkness At first It'll start with a small roll, then a second or so after It'll turn into a rather violent spin.

@SimpleTechAndResearch Nothing really BETA here besides some adjustments in the 0.75 region.

Does it roll a little bit or violently spins out of control?

@Glaceon If it wasn't beta maybe I could've

@SimpleTechAndResearch Kay.

Well I can't help
