Sure it is.... Regular zippy quick and highly responsive 300 series Lancairs have about a 23' wingspan.  The extensions make it about 27'.  There ya go....

 

Grayhawk

 

PS.  If I remember correctly, the wingtip attaching rib is at about BL129 (10' 9") and the standard tips are about 8"-10".  The extensions are 24".

 

I'll take a real wild guess and say that that was probably not the missing bit of information Mr. Arjad is looking for.
