No, in your opinion they are garbage Tall Paul. Then again, having never flown a correctly configured one, which I'm guessing is the case for you, you would have a biased opinion. Everbody knows they have some flaws, and most know what they are and can take care of it. When done, they (reflection, RCU bipe, and turmoil) fly great. I'm not sure a 350 mah lipo will even be able to supply the amperage to fly the plane. It may get really hot really fast and exploade... If it does have the dicharge rate to handle the motor and ESC, then your looking at maybe 4 minutes. My 640 mah only gets about 8 or 9 minutes...
