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 ?? http://www.youtube.com/watch?v=Hl0EXJ0RUkA Title: Re: Freestlye RC aerobatics -explanation required Post by: anwar on May 28, 2013, 09:51:44 PM http://www.rcindia.org/search2?search=vpp
VPP = Variable Pitch Propellor. Same way RC Helicopters hover/fly inverted. Title: Re: Freestlye RC aerobatics -explanation required Post by: RCNeil21 on May 29, 2013, 12:11:25 AM 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 - http://www.hobbyking.com/hobbyking/store/__6298__Variable_pitch_prop_motor_set_9_Type_B.html 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 http://www.youtube.com/watch?feature=player_embedded&v=NfTdbbTE77A Title: Re: Freestlye RC aerobatics -explanation required Post by: santhosh-r on May 29, 2013, 06:55:22 AM 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?? Title: Re: Freestlye RC aerobatics -explanation required Post by: rcpilotacro on May 29, 2013, 09:41:52 AM Santhosh-r
