This guy was doing flat spin on the RV?
He was doing all kinds of spins including a flat spin (upright and inverted) on a training Pitts S2C
Do you undestand what flat spin is? No difference than any others in reality as far the aircraft (any model) is concerned....
Since your are thinking "DEAD TRAP" "AIRCRAFT OVERSTRESSED" let's explain further........on a Lycoming/Continental powered aircraft you can only Flat Spin to the Left. You can spin to the right all you want, but it will never ever be a Flat Spin...Opposite for Russian Engine Driven aircraft (propeller turns opposite) You can only Flat Spin to the Right....
To achieve a Flat Spin, you need first enter a normal spin by reducing all power, holding your stick back and pressing your full LH pedal (causing the aircraft to YAW left). Once you are on a fully developed spin, place your stick in the 5 o'clock position and add power. The prop wash over the elevator will push the nose up (FLAT FUSELAGE IN RELATION TO THE GROUND) and slowing your rotation speed...
VOILA...you just achieved your FLAT SPIN. (SAME INVERTED but Stick needs to be in the Upper 2 Oclock) ...to stop, cut power commpletelly, place the stick back to the 6 o'clock position and apply full opposite or RH rudder until rotation stops. Easy your stick position back to center until you acchive 80 to 100 kias and return to SL flight...
If you forget what to do pleas apply the Emergency Recovery Procedure.... ...cut power, center and hold everything (DO NOT RELEASE LIKE OTHERS RECCOMEND SINCE IT WILL TAKE LONGER) and wait, wait wait until aircraft stops rotating on its own, achieve 80 to 100 kias and return to SL flight. YAW controls everything on a SPIN and once you remove YAW (center the pedals) the aircraft tendency will be to start flying again....
Let me ask you another question....how many G's do you think the RV or any other aircraft experiences during a spin? you might be surprise by the correct answer. I have several videos to proof my statement but during the entry and during the Spin less than 2 g's you will get more G's at pullout if you are anxious.
I am not an expert of Spins myself but have flown several of them in all different attitudes in different aicraft....I have a great level of confidence during spins having attenteded Bill Spin and Emergency recovery procedures for many years. We start all our SPINS at 7,500 ft. AGL and recover no lower than 3000 Ft AGL....
Sorry for any english language or grammar errors...English still my addopted language!
