Randy,
Whatever you decide to do with the Stunt Machine I am sure it will be very cool and I am looking forward to seeing it. I have also been a fan of this model for quite a while, beginning with when I first saw it in flying models. I have to admit I am getting a little confused on the development history as there were a few versions, some of them quite a bit larger than the published version. And then the published version had some variances from the actual shown with Gene in this thread. I have posted pictures of mine here before and have added another today as it may help to generate interest in "the machine". When I first built mine I installed a Magnum 36 but I have since switched to a Brodak 40. I am working on getting a 35S (as was used in the original) and will put it in if I can provided I don't have to rebuild the motor mounts and cowl.
Regards,
