Steven Wilk designed & built the Septzilla for Dave Fisher.
It's powered by 7 Fora 15 F2D motors. That is 105 cu in of motors.
Lines are .037 x 65' the LE has reinforced Carbon fiber main & LE Aspen spars.
It was designed to fly like a combat plane, provided that Dave Fischer could hang on to it.

Dave Fisher was flying Septzilla.

I always wanted to buy Fora motors but I never bought them because they're quite expensive.

Each Fora 15 F2D motor costs $240
