To the Wasp I must say that it was good to hear that your B2 lifted off so well at such a low speed, I have been concerned about the the airfoil since its so thin. Have not flown mine yet but Im getting very close to that day. Now that there are several guys out there flying with the Valach 60 and posting on you-tube and whatnot, I see that this motor has power to spare and a beautiful sound but it might not be a good choice for someone who wants any speed. Im glad thats not my need at all, many years ago that might have bothered me but these days just up and around the patch is all I ask. With a higher pitch Prop this engine might surprise us with some decent speed, I will look into that after I get things off the ground. Happy landings. JIM
