Well that was a close call

I was flying my parkzone radian glider in a field by my house and all was going well till i lost all control of the plane, it was odd it stayed level and brought it self back into radio range where i once gained control again, then lost control yet once again. This time the plane went full throttle and nosed itself into the ground from an altitude of about 150ft at 50mph.I found the plane about 5 minutes after the crash in the grass sitting upside down about 9ft away from the bay window of an apartment. The odd part is that the plane is still in one piece and still flyable. This is not the first time the receiver has crashed a plane, the first time was with my nitro plane, so i figured it was the fact that i put a parkflyer receiver in a nitro plane
