no offence to the guy that made 5D but since when have planes been able to travel through time too?

strictly speaking its still 3D but i think 4D would be a good name for it, god knows where 5D came from...

in respect to the 40%er question, i'll be flying a 40% funtana at the freestyles in september in the UK with vari pitch props all being well

if not then i'll have to settle for a .90 sized with vari pitch prop
