Hi David,
Thanks, I'm searching on the web to collect true and complete info about these 4 models which they all belong to almost a same era
1) mystic
2) supra fly
3) joker ( as you know it's not Prettner's design and belongs to W. Matt)
4) supra star
mystic plan seems to be very rare , i couldn't trace it on the web instead of a low res 3-view
supra fly 25 plan is available at outerzone.co.uk
joker 25 could be found there too
but the supra star, i personally like its profile and think its building project would be much easier than the 3 others
infact i was aiming to do a complete thread after my incomplete tiny curare
And my first candidate was mystic but because the lack of enough data i prefered to have a brief look on supra star
if i start its project it'll be a 50 size bird
and about tiny curare
its progress stoped because i just work on my birds when i have a mind full of interest, a strong stimulator that forces me to do what should be done, and now i guess any trying to complete that project will result in a low quality bird and thread because of the lost interest
Some day it will be finished the way it must be
Regards,
Ehsan
