UHU...flying wings aren't really beginner models. You have to be really easy on the sticks else you will dork it. I would get really good
with what you have now and then get a Unicorn or Wing Warrior. Just go with a speed 400 6 volt motor at first. Get used to it then
put in a brushless motor. Those are about the 2 best wings that I know of. I have a brushless powered 'Corn myself.
