HI I'm building a kit sig 4* 60 and I'm to the point of installing the motor mount to the firewall and building the fuselage around it. the mount is installed by using hidden nuts type setup. the problem is, I wouldn't be getting the O.S 61 FX 2-stroke until Christmas Is there anyway I could continue building the plane without the motor? I would like to use the motor mount that came with the Sig kit. Also would this be the right motor for this plane? thank you
