Hello friends,
Please explain me how this guy in the video can make the plane go in reverse vertically ?? Did he use a ESC with reverse like a Car ESC ??

VPP = Variable Pitch Propellor. Same way RC Helicopters hover/fly inverted.

Yes anwar sir is right. It is known as 4D flying. And usually goes by the name 4D VPP
Here is a link to a motor that has VPP for 4D -

I think type B means that the VPP assembly is a pusher when the controlling line is not shifted and is at the lower most position. As i am not an expert in 4D VPP i could be wrong. :(

And that guys video is not as good as this ones he does spot takeoff

Ok...so it is variable pitch prop in a outrunner with a servo to control the pitch of the prop....Got it...

But if it goes in reverse won't the ailerons / elevator( trailing edge) first hits air than the leading edge ?
There will be problem in control inputs isn't it??
