Question
how would this work for a set up for a really heavy fomie

my dad and i had this crazy idea
we were flying an f22 one day and crashed the nose into the ground
i said "lets build this plane out of fiber glass"
i know i know crazy but we think we could make it work
i want to know how this set up would work for a really heavy fomie
our plan is for this to take a while to plane out and build
this is what i have picked out for this plane

motor:

speed control:

battery:

two servos:

i know it says heli but i was looking for cheap metal gear servos
if these wont work please let me know

and i need a suggestion for a good prop
it recomends a 11x6 but i dont think i want it that big
so i liked this setup but i dont really know much about picking parts out so if anything on here doesnt work with something else please help me out

thanks guys its much appricated

I'm not sure it counts as a foamie if it's not made of foam .

D'you want to be a bit more specific about "really heavy" ? If it means 3 or 4 pounds that setup might be o.k. If it means 34 pounds it definitely won't. And that motor will typically be running at around 25-30A so an 1800mAh battery will give pretty short flights. And if the plane is too heavy for its wing area it won't fly at all .

BTW fibreglass doesn't take crashes nearly as well as many foams. You get millions of splinters all over everywhere.

I'm kind of a newbie to RC and my experience with a foamie F-22 is this: There is a critical banking angle for every speed, and if you exceed this angle, you enter immediately into a death spiral which 99% of the time is not survivable.
You can barely sense when it's starting to increase the bank on its own and that's the point where you reduce that angle or increase the speed.

the inner parts of the f22 are made of foam
its gonna be kind of like a shell
we are planning on making it look really pretty
with some nice retractable landing gear and it prolly wont be a very slow flyer
my dad and i are thinking somewhere around 2 pounds
as long as you fly fast enough it will fly right?
