Bar one ...
This odd one out is called the Junior, a smaller Stunter produced in the UK. There is very little information on this particular version on the internet. Sleuthing by a member of the Peter Powell Kites Owners Group on Facebook unearthed announcements for prize draws in two comics magazines from 1976 where 500 Peter Powell Junior Stunters could be won.
One in Cheeky Weekly:
and one in Crazy Comics:
The drawings of the Junior Stunter in these two announcements suggest a fundamentally different design for this PP Stunter: no leading edges, upper bridle lines connected to the cross spars, and cross spars behind the sail.
With thanks to Paul Powell, who alerted me to a Junior offered for sale on Gumtree, I managed to get my hands on this 'odd' Stunter! Wing span is around 3' (92cm), compared to the 4' wing span of a standard PP Stunter. And indeed, the kite does not have leading edges as well as cross spars. A single pair of spars performs both functions, is situated behind the sail, and the upper bridle lines connect to it through a circular hole in the sail.
Time to fly it to see how it behaves in the air. At some point in the past, Mark or Paul mentioned to me that Peter didn't particularly like the Junior; curious as to why ...
Of course, we did fly it with original lines and handles.
The Junior handled well in very blustery wind (mostly 14-27mph). It's faster than a standard-sized PP Stunter, turns quicker, and generally feels nimbler on the lines.
I honestly can't think of why Peter didn't like the Junior based on its flying characteristics. And I'm very pleased to have been able to add a Junior Stunter to my collection. Thanks again, Paul!
