The Scientific F-100 Super Sabre - Everything about it is all wrong

I'm with you Robert! I also enjoy fixing-up a neglected article.. particularly if it's something old. I believe that you were check-fitting a faux jet-engine/tail-cone to this model; made from the cap of a squeeze-type apple sauce snack container. I can relate (fully) to what you were after.. and your full-scale/rear-view F-100 photos backed it up.

I've been struggling with my T33-Dee.. to muster the testicular-fortitude to fly it with a Tee Dee .049/.051 engine, which is what I designed it for. It's a smaller model than your Super Sabre; at 15" span and 13" length. I designed it for the CEF Speed Contest Tee Dee class.. but still haven't got a fuel-delivery system worked-out..  

You likely discovered that your F-100's nose-gear (wire) incorporated a "loop" between the engine/firewall in order to lock its position/attitude securely. I would personally replace the gear-wire with one having a "coil" wound into it.. which would provide some "spring-suspension".

My P-38 has this arrangement.




This may add weight.. but if you're planning to lengthen the fuse for a more scale-look.. (as well as adding the missing elevator) then you may well need some added nose-weight.

Maybe you're not planning to make the model airworthy.. but you could.. (while you're thinking..)
