Playboy Sr. CG

Postby Tex Mike » Sun Oct 09, 2011 3:47 pm

I am a new mwmber and have been building rc since 1963, and am now BACK to oldtimers. I have a new Playboy Sr I built from plans with a os 40 four stroke.
I would like to know where to CG this radio assisted plane. I built off 1941 plans for free flight. The 25% rule looks to far faward. Can someone give some help????
Thanks
Mike

yes my Favorite competition model here in oz oldtimer.ok mine fly best with CofG at 50% of main wing {both pylon and Cabin model}
the tail is set at 0deg in relation to the main wing.
be brave stick a mccoy 60 on glow running 60% nitro and 13*4 prop and watch her go vertical 1
have fun they a great bird to fly.
