Thanks , Both model are close in size , the x-1 is 36" ws 38" long
built several of these - most were E-F rocket powered 4 motors
fired 2 at a time , one model was Freon Powered .Both have
the second had a 38"ws and was 40" long this was powered by
a cox 15 racing nitro engine connected to a centrifugal system .
the fan unit is shown in foreground - air inlet was under model
to allow starting the nitro motor, both these model had crude AP's
the newer jet had a auto duel rate system .
both models were in the 3 lb range , since these were built in early
70's it was before video .
I thinking of building another x-2 here in the scratch built section
soon to show off our now working centrifugal fan.
tryed to build a new version of this 3 years ago but ran in to problems
now working properly , just needs some more development to increase
top speed , whick is why I'm thinking of building another.
the videos below are of the fan flying
building a seethrough model for testing /demo's will post when complete
