dunno... the aircore trainer flew pretty well IMHO...unless a plane that flies itself (no engine) after a direct high speed headon for a good while...because I was convinced it had perished as well..is what all palnes would do...

ugly?..yes....(though IMHO less so than a self constructed SPAD)...useful?..definitely.

to furthe my point..I had convinced a friend of mine to get into flying...his plane lasted ONE flight...(control linkage failure)a complete writeoff...he quit. Maybe he would have all the same...with the aircore... but I doubt it...

my .02...
