See, now no one needs to do this to find out if the VPS system cancels out GPS.I would suggest to NEVER do what this guy did!! He got really lucky that the blanket didn't fly up into the quad.
I've seen it happen when a buddy used a piece of carpet as a landing pad for his T-Rex heli. Completely destroyed the bird. All it takes is for the wash to get under the blanket and it's game over.
Edit: Here ya go!! Not my buddies crash but pretty much the exact same scenario.
I took the risk so that other people don't need to.
You are welcome.
