Ive been torturing my self to make this(im not a very good builder so it was very hard for me to make this). The plane has a few problems that i could not fix. When ever you try taking off, dont pull up too hard or else the plane will do a cobra and stall out.
Second, if you do manage to take off, for some reason the plane wants to go down, and then at slightly higher speeds, it starts going up, and then at higher speeds it starts going down.
Third, do not try landing in the water with this, if you do, the plane will blow up.
Fourth, this does not have any stabilzing vizzy so you will have to stablize the plane all by yourself.
Fifth, if you try doing a cobra or any extreme manuver past mach 1, most of the plane will explode from the G-Forces
Anyways, the plane can reach mach 1 for sure, but its hard for it to reach mach 1 since the problems i listed above(most of them) make it difficult too reach. The plane can do a cobra pretty easily, it can fly at low speeds, and the turn rate is good too
And uhh thats all
Note: if you do experience any problems, please reply with feedback, and ill try to fix it.
