It is the 1/5 that is 72"---same as the Stearman---I have both----It appears Pica may not be Pica anymore & may have sold out to another company as thier site is no longer accessable & the sale of the company has been mentioned in other forums. Grab a kit while you can---Quantum RC had the best price @$209----or buy mine----it's never been flown & cowl is cut for a Saito 100.
