Hand propping is inherently dangerous and ANY attempt to start the engine in this manner could kill you. The following is not an endorsement or recommendation of any procedure. It is merely an observation after seeing many techniques tried. Walt is right...and I've seen it happen. No air but a perfect alignment for ignition and the engine springs to life when the start button is pushed. With just the wrong timing your hands (or worse) can be good material for the latest Ginsu commercial. Another technique that seems to lower the risk (again, do not attempt this at home) is to get the plane set up and stand clear of the prop while the start button is pushed. Once the "Bzzzzzzzzz" of the exciter is heard and the prop still dead, then walk up to it and give it a whirl. I've done the other way (the Russian Roulette technique) and just been plain lucky to not get hurt. Seeing the thing fire without air convinced me to never do it the old way again...and count my blessings that I didn't get a call from Ginsu. -- Barry Hancock Worldwide Warbirds, Inc. office (909) 606-4444 cell (949) 300-5510 www.worldwidewarbirds.com ________________________________ Message 2 _____________________________________ Time: 08:08:57 AM PST US From: Markus Feyerabend Subject: Re: Yak-List: Hand Propping Heres a clip of Jurgys Sukhoi getting hand/rope propped... http://www.youtube.com/watch?v=Azi0VP8IFg0 Id think that when wearing proper gloves and paying attention not to loop the rope around your hand etc. it looks safer to me than by hand propping directly at the prop...

However, I would fell a little more comfortable being a bit further away from a 360/400hp shredder... He used to run a 4 blade prop some time ago, but the more recent pics show a 3 blade again. And the plane on your picture shows his SU-26, whereas the one in the clip is was LY-LJK, his SU-31... > -----Ursprngliche Nachricht----- > Von: "pilko2" > Gesendet: 23.03.09 17:24:47 > An: > Betreff: RE: Yak-List: Hand Propping > Jurgis normally runs a 4 blade prop not a three as illustrated here. > > No matter the CAUTION note to hand propping still applies ! > > -----Original Message----- > From: owner-yak-list-server@matronics.com > [mailto:owner-yak-list-server@matronics.com] On Behalf Of Markus Feyerabend > Sent: 23 March 2009 15:08 > To: yak-list@matronics.com > Subject: Re: Yak-List: Hand Propping > > > Heres a clip of Jurgys Sukhoi getting hand/rope propped... > http://www.youtube.com/watch?v=Azi0VP8IFg0 > > Id think that when wearing proper gloves and paying attention not to loop > the rope around your hand etc. it looks safer to me than by hand propping > directly at the prop... > Ive got no experience hand propping a radial engine though and Im already > intimidated enough to pay extreme caution hand propping a Lycoming or > similar engines.... > > just my 2 (Euro)cents, > Markus > > > > -----Ursprngliche Nachricht----- > > Von: "Barry Hancock" > > Gesendet: 23.03.09 15:53:28 > > An: yak-list@matronics.com > > Betreff: Yak-List: Hand Propping > > > > --> > > > > Guys, > > > > First, a disclaimer.

Are you willing to part with it for a price? Or is there a way I can get the details to have one made locally? Regards, Anthony.
