Latest decision from the USRA listed below. Please uderstand that we are growing as we learn about the Sundowner.
Mine is 14 lbs with a Lipo for the ignition battery and a 2500 Mah NiMh, nice digital servos, Radial engine mount.
To get to min weight run Lipos all around, lighter small servo's, Hollow tail rods. You can't remove any material from the planes structure. we have one guy who is sub 13.5 so it is doable.
Mike S. With all due respcect I think your speed gun is reading a little high we are having a tough time breaking 100 MPH using the Evo 35
