Thanks
If I remember correctly 200 gsm was the minimum weight I found for structural fiberglass cloth. Which one are you using?

after a long waiting the shop did the repairs and mods i requested to the Stephens Akro wing > general check; > repair of some cracks; > increase in main spar height by 19 mm / 0,75 inch (max possible without modifying the fuselage), so now the max thickness is about 13% in the center section, decre...

There is one in Italy. It is an original design i do not think the plans are for sale.

It happened something similar to me: my pitts flies straight with the stick centered but if I release the stick it moves to the left slightly and the aircraft rolls to the left, with or without spades. It did it also after a complete rigging so I ended in placing a rubber strip P shaped (the ones us...

Usually you try to have the airplane balanced, i.e. no roll, without spades but maybe it is better not to fly without spades with the laser since spades are balancing the ailerons weight. Other thing you can do is to check whether the spades are parallel so if there is a roll it is not because of th...

Thanks Dave
