I too was not sure of the spool up with the 16X4W... But man it throws alot
of air... which I did notice on hovers of the 4*... Tho, the spool up was slower
the added air made up for it so I'm still checking it out, I also picked up a
15X6, but did not try it yet....

Yeah.. They are sure building a lot here... We thought with all this heat.....
It may still be a while... They can only play with dirt now..., piping work is
1-2+yrs away.... But with the playing of dirt... It may shorten the runway by
40'........ Maybe that's why I got the 100... The 4* can get up in a few feet,
with the 100 on the UCD I could problely hand launch it And you could
always do an "upright" flat spin landing
